Maximum economic efficiency in superlength

Sophisticated drive technologies for long and superlong machinesSuperlong machines are increasingly in demand for commodity production. However, superlength places considerable demands on the system because the torsional forces occurring must not affect the quality of the yarn. The bottom rollers in particular are subjected to a torsion that the Zinser 351 counteracts with stronger middle bottom rollers. An auxiliary motor at the centre of a machine, which is generally used on other machines, is not an option for the Zinser 351 because it takes up space – impairing productivity per sqm – and requires additional maintenance.

Only with Zinser: 1,680 spindles with maximum use of spaceA cost-effective way of neutralising torsional forces is put into effect by the Zinser 351’s stronger middle bottom rollers. Their diameter of 30.5 mm, instead of the conventional 27 mm, makes them 20 % more resistant to torsion.In addition, drive motors fix the middle bottom rollers in place when the machine is stopped. This ensures high Zinser spinning stability at super-length – cost-effectively, without auxiliary equip-ment and without requiring extra space. As a result, the Zinser 351 is the most economical ring spinning machine in the world. Make maxi-mum use of your square metres, for more pro-duction per sqm.

Process reliability at the highest speeds

Higher speeds with OptiStepEnsure maximum productivity with OptiStep. The start-up, tip and main spinning speeds can be defined very accurately by a 10-point speed curve. This means you can operate far closer to the technological spinning limit across the entire bobbin build and achieve peak production. The traveller service life is also extended.

Low maintenance, energy efficient and highly productiveFor Schlafhorst, quality technology means highest quality compo- nents at the crucial points. The main distinguishing feature of the Zinser 351 is therefore the drive technology. With its maintenance- free, energy-efficient tangential belt drive, the Zinser 351 combines highest productivity with outstanding efficiency.

The low energy consumption is the advantage of the Zinser tan-gential belt drive. This is the result of the low number of deflec tion points, which ensures a straight-running belt without twists and a small belt surface – for less friction and minimal air turbulence. The highly uniform surface of the belt is crucial for quality. The spindles are steadily driven in a gentle and completely vibration- free way. The advantage: the variation of the spindle speed is below 1 % with uniform yarn twist.

Without additional cooling circuitsThe engines make a difference, too: The spindle and drafting system drives are powered by energy-efficient motors. The drives are designed specifically for the output called for in the spinning machines and they do not heat up. This means: costly energy is converted to speed, not heat.

As secure as a gear wheel: Monitoring and control through sensor technologyThe fine tuning of speed, twist and draft is essential for productivity and quality when ring spinning. It must be assured at all times that the values set are actually realised across the entire length of the machine. That is why the Zinser 351 relies on state-of-the-art, fully controlled drive technology: All speeds are sensor-monitored online and precisely readjusted on an ongoing basis in real time. As a re-sult, the drive concept combines the operational comfort of electro-nic control with the accuracy and dependability of a gear wheel.

Software-supported control circuitSpindle speed, draft and twist are controlled online. The system sensor-controls both the motor speeds and the actual speed of the drafting system’s bottom rollers, synchronises the values among themselves and readjusts, if required, in split seconds.

Maximum productivity, satisfied customersThe Zinser 351 achieves extremely low yarn break rates on account of this highly precise all-round control of every spinning parameter. The yarn count cannot change subtly and unnoticedly – consistency in the yarn quality from spindle to spindle is guaranteed.

Precision and quiet running at highest speedsZinser high-speed spindles are another reason for the high productive capacity of the Zinser 351. The precise and highly stable high-speed spindle bearings in particular ensure absolute quiet run-ning at top speeds.

The spindles are economic because of their low energy consumption. They do scarcely require maintenance and have a long service life.

Spindles with the new Zero Underwinding concept ensure the prevention of underwound yarn ends. For precise functioning during all stages of a spinning cycle – no wharve cleaning is required.

All-round protection for your quality

Operating technology assuring the highest qualityAll Schlafhorst machines stand out because of their market-leading, ergonomical operating concept. Your employees have the status of the machine, including all current process data, in view at all times on the big coloured EasySpin touchscreen – for maximum quality assurance.

Your staff are routed to the right setting quickly and securely: with images and icons and in various languages. Every input screen of-fers practical tips. Illustrated messages provide targeted information about actions that are required.

Central setting, consistent yarn qualityWith the Zinser 351, you produce quality bobbins that are as like as two peas in a pod. EasySpin and ServoDraft make mechanical set-tings unnecessary – they ensure the consistency of every machine. Every important spinning parameter and machine component, e.g. spindle drive, FancyDraft and CoWeMat, is centrally controlled. Central settings minimise adjustment errors and eliminate inac-curacies. Store your lot data in the EasySpin article data archive or use a USB stick; this ensures maximum reproducibility at all times.

EasySpin Safety in case of power failures

Maximum productivity in case of power failure The Zinser 351 buffers short power failures up to 2 seconds and continues running without yarn breaks. For this purpose, the mains power failure support system continuously monitors the power supply and the speed of the machine. If the power fails, the spindle drive motors operate in generator mode and supply the rest of the machine’s motors with energy.

In case of a longer power failure, the machine shuts down gracefully. After the energy supply has been restored, the machine starts running steadily again without further yarn breaks. As a result, no additional effort to remedy yarn breaks is needed and thus no extra labour input required.

ZINSER 35112

Highest flexibility

Networked quality and production managementBy using the Plant Control System, you are always up to date as to the staff deployment and the effi-ciency level your system is currently operating at.

Your Schlafhorst product lines are linked up via a system network employing a central computer. All production and quality data are acquired online and are available by mouse click as shift or pro-duction reports. With information prepared in detail, you optimise your operational application flows and thus increase the economic success of your company.

Central data management

Create room for decisionsWith the Zinser 351, you are investing in a technology platform that provides you with maximum freedom. With additional options like FancyDraft, FancyDesigner, CoreSpun and SiroSpun, you are making your ring spinning machines fit for new fashion trends at any moment and expanding your product portfolio with new yarns. Because a niche application today can already be standard tomor-row.

Simply upgrade to 2Impact FXThe Zinser 351+ model can at any time be upgraded to 2Impact FX, the unique self-cleaning compact spinning technology, with little effort:– automatically self cleaning– equipped with a separately controlled vacuum unit– variably adjustable in its compact characteristics.

Lower spinning costs

Reduced friction, maximum energy efficiencyThe most important advantage of the Zinser multi-motor single tangential belt drive system: It consumes less energy than other drives. Thanks to fewer deflection points and belt deflections, fric-tion is minimised and energy consumption is reduced as a result.

Maintenance-free tangential beltThe Zinser 351’s multi-motor single tangential belt drive system does not require maintenance. If the belt change is made a part of the routine maintenance of the machine, you reduce mainte-nance-required downtimes to an absolute minimum – for the maximum economic efficiency of the system.

Spinning, not cleaning Additional advantages of the tangential belt drive: It is encapsulated and the belt surface area is very small. That is why it does not ge-nerate any air whirl in the machine, such as the drum shaft of a 4-spindle belt drive. The staff costs for cleaning the Zinser 351 are therefore minimal.

Energy-saving, low-maintenance drive Energy efficiency with OptiSuction

Less energy, more incomeThe intelligent OptiSuction sensor-monitored yarn break suction system ensures maximum energy efficiency. Its vacuum control always supplies the precise amount of vacuum needed, independent of the fill level in the filter box for fibres.

Actual value equal to nominal value – at all times Settings can be configured conveniently on the EasySpin touchscreen. As a result, you produce economically and reliably because the vacuum is always optimally adjusted to the raw material and the yarn count. Constant negative pressure across the entire bobbin build is ensured with this closed control circuit.

Automating means profiting

Producing independent of personnelIt is becoming increasingly more difficult for spinning mills to find steady employees. As a result, the automation trend is gaining greater momentum worldwide. But automation also increases, ensuring yarn quality.

Schlafhorst provides you with cost-effective and customised automation solutions:– for the roving frame and roving bobbin doffing– for transporting roving bobbins to the ring spinning machine– for doffing and the transport processes at the ring spinning

machine – for transport solutions from the ring spinning machine to the

winding machine

Flexible with the stand-alone solution or maximum efficiency with linked systemsDoffing automation with full flexibility or maximum economic efficiency for large lots – it is your choice:

The Zinser 351 as a stand-alone machine with CoWeMat 395 F fits any space situation because it is spatially independent of the package winding machine. It enables you to produce flexibly and saves on personnel in particular thanks to CoWeFeed, the unique unsorted tube feeding.

The Zinser 351 linked machine with CoWeMat 395 V can be linked to any commercially available pack age winding machine and reduces your labour and space requirements to a minimum.

Doffing automation with maximum efficiency: CoWeMat

Uniquely time-saving: CoWeFeedZinser has the solution with the lowest labour input: CoWeFeed, the unsorted tube feeding. The empty tubes are simply dumped into the feed container – no sorting is required. One filling is sufficient for a full takeoff, even with superlong ring spinning machines.

Operates without problems thanks to clever designJammed tubes will not cause CoWeFeed to malfunction, regardless of their position and orientation. Even with 1,680 spindles, removing the bobbins and feeding the empty tubes is carried out rapidly between two doffings – for maximum productivity.

No controls requiredWorldwide, the Zinser CoWeMat stands for the most economic doffing technology. In the case of other doffing systems design-related malfunction risks are known, which require persistent controls. Here, individual leaks can even cause machine stoppage. Not so with CoWeMat: If a gripper malfunctions, the CoWeMat and the machine continues to run. This is because every outer gripper is supplied compressed air separate from the machine’s vacuum system. Moreover, the safety membrane in each gripper ensures that no air-ducting elements are not subjected to mech-anical stress.

Even for high-tenacity yarnsA light barrier monitors the smooth application flows of the doffing. In case of a malfunction, the machine shuts down automatically. Even high-tenacity yarns are safely cut.

Zinser BobbinTray – for greater productivityThe Zinser BobbinTray system transports bobbins and empty tubes without contact, thus ensuring high Zinser yarn quality as well as highest productivity.

Lowest labour input, highest reliability

Maximum economic efficiency in linked systemsA linked system involving superlong ring spinning machines pays, particularly for the continual production of big lots without many changes. Many efficiency factors can be taken optimal advantage of, e.g. use of space, synchronisation of winding and spinning capacity, minimisation of the labour requirement and quality management. As a result, efficiency is increased and production run times are significantly reduced.

Little effort is required on your part to link the Zinser 351 with CoWeMat 395 V with all commercially available automatic package winding machines.

Higher package quality, highest efficiencyThanks to contact-free transport of the bobbins, the quality of the yarn spun remains retained at 100%. The advantage: Thanks to yarn-protecting bobbin transport, trouble-free unwinding with the lowest yarn break rates and highest efficiency and quality can be expected.

Maximizing efficiency in linked system solutions Roving bobbins transport

Transport automation made to measureSchlafhorst provides you with custom roving transport automation for the Zinser 351 from any commercially available roving frame, suitable for both your spatial requirements and your budget.

Up to 35% less personnel costsCompared to manual roving transport, you can save on personnel costs, e.g. for coarse yarns with CimTrack 3/4 creel automation, up to 35%.

More productivity, more reliable quality– No roving bobbin contact, no package surface

damage– No intermediate storage that could cause

damage to or soiling or aging of the roving– No mix-ups– Clearly structured material flow, acceleration of

your processes– Equalisation of work application flows and

smoothing of peaks in the labour requirement
