Pivoting frame system ELGUIDERFunctionOn an ELGUIDER pivoting frame system, the web changes direction four times, each time by 90°. The system is based on a pivoting frame with two path rollers. The imaginary pivot point is located on the infeed plane. La-teral web corrections can only be achieved by pivoting around this pivot point. The prerequi-site here is always sufficient tension for tracti-on between the web and the guide roller.

Area of useThanks to optimized exploitation of the elast-icity ranges, the pivoting frame is particularly suited to use even in really tight spaces.

ApplicationThe greater the web tension, the module of elasticity and the required correction, the lon-ger the infeed, exit and transfer paths should be designed. Experience has shown that these paths should be the equivalent of 60 to 100% of the web width. The sensor should be posi-tioned behind the positioning roller, as near to it as possible.

Steering roller system ELROLLERFunctionELROLLER steering roller systems already correct the web position on the infeed plane. They consist of a fixed base frame and a mo-vable guide frame. The latter accommodates one or two positioning rollers and swivels round an imaginary pivot point on the infeed plane. The pivot point should, on the one hand, be far enough away from the infeed roller to ensure that the web correction does not in-fluence the infeed roller. On the other hand, it must be far enough away from the guide roller to ensure that the elasticity of the web may be fully exploited but not over-strained. A steering roller is termed a proportional actuator. It must therefore operate friction-locked and must not permit any sliding between the web and the guide roller.

Area of useELROLLER systems are always used where there is a long entry path due to technical pro-cess reasons.

ApplicationDepending on the space available, steering rollers may be fitted with one or two guide rol-lers. On versions with one roller, the web is guided with a wrap angle of 90°. On versions with two guide rollers less wrapping is possib-le. In this case, the web runs at almost the same level as the outfeed roller. The following applies when mounting an ELROLLER: the in-feed path should be the equivalent of two to three times the web width, the exit path should be between 50 and 100% of the web width. The sensor should be positioned behind the positioning roller, as near to it as possible. As a result, improved control dynamics are achieved thanks to the resulting short res-ponse time.

Winding station control ELWINDERFunctionIn production processes with moving webs, there is typically an unwinder at the machine infeed and a rewinder at the exit. During un-winding, the winding station is moved via a li-near drive to feed the web in the desired positi-on. On the other hand, during rewinding, the winding station follows the constantly changing web position via a linear drive to achieve an evenly wound reel.

Area of useWeb guiders with ELWINDER winding stations are used wherever it is not possible to use ELGUIDER or ELROLLER systems due to lack of space.

Application, unwindingDuring unwinding, the sensor is mounted on the machine to define the target web position. Here, the position detection system should be located as close to the final winding station guide roller as possible.

Application, unwinding with synchronous rol-lerIf, for space reasons, it is not possible to fit a guide roller to the winding station, it can be designed as a synchronous electrically coupled roller.

Application, rewindingDuring rewinding, the sensor is fastened to the winding station to set the target position of the winding station for the controller. Here, the po-sition detection system should be located as close to the final machine guide roller as pos-sible. The guiding path L1 depends on the elasticity of the web. The larger the transverse elasticity range, the shorter the path L1 can be. Experience has shown that the guiding path should be the equivalent of half a web width.

Flange load cell ELTENSFunctionThe load cell comprises a stable outer ring with flange cover and centering collar for pre-cision assembly. The inner ring in the form of a double bending beam ensures centered mounting of the ball bearing. The radial forces produced by the web create an imbalance in the strain gauges linked together to form a measuring bridge on the inner ring. This leads to an analog output signal proportional to the web tension.

Area of useFlange load cells are used in practically all pro-cessing plants where web-type materials are processed or finished. In front of processing stations, in particular, it is of fundamental im-portance that the web is transported with a continuous web tension.

ApplicationWith a 90° horizontal-vertical wrapping angle on the measuring roller and a horizontal mea-suring direction, optimum web tension mea-surement is assured. Only detection of the bearing forces on both sides can prevent in-correct measurements caused by the web mo-ving sideways and asymmetrical web tension distribution. Load cells incorporated into a control loop should be mounted as near to the actuator as possible.

CalibrationThe tensile force – path characteristic curve forms a straight line to the mechanical stop. All load cells with the exception of the PD 25 series are calibrated to the nominal measuring force. Between the nominal measuring force and mechanical stop, a safety factor of 50 to 100 % is taken into account to compensate for asymmetrical web tension distribution.

Flange load cell ELTENSFunctionThe flange load cell for cantilever machines consists of an outer and inner ring for one-ended mounting on the machine wall. The inner ring is designed as a double bending beam for force acquisition. A single-ended low bearing friction roller with inner bearings can be mounted on the front. The position of the web or an asymmetric web tension distribution has no effect on the measured result.

Area of useFlange load cell for mounting low bearing friction rollers with bearings on one end are used especially in the hygiene and battery industry. In front of processing stations, in particular, it is of fundamental importance that the web is transported with a continuous web tension.

ApplicationWith a 90° horizontal-vertical wrapping angle on the measuring roller and a horizontal mea-suring direction, optimum web tension mea-surement is assured. Load cells incorporated into a control loop should be mounted as near to the actuator as possible.

Block load cellsFunctionBlock load cells comprise a cast housing for adaptation to the customer's machine and a mounting plate to accommodate the pedestal bearing. The measuring force is detected via a double bending beam to which the strain gau-ges are applied, as a result of which an analo-gue measured signal proportional to the web tension is output.

Area of useBlock load cells are used in practically all pro-cessing plants where web-type materials are processed or finished. Above all in the con-verting sector they offer significant advantages, as the rollers can always be replaced easily due to the very good access to the pedestal bearings.

ApplicationA horizontal mounting position is preferred with symmetrical wrapping between 60 – 180° in relation to the vertical measuring direction. Measurement of the web tension on both sides prevents incorrect measurements caused by the web moving sideways and asymmetrical web tension distribution. Load cells incor-porated into a control loop should be positio-ned as near to the actuator as possible.

FunctionLine scan cameras measure the position of the coating in relation to the outer edge (reference edge) using the incident light process. Positi-ons and widths of the coating are transferred to the customer's control system via Ethernet.

Area of useTypically 3 coating strips are applied to the top and bottom of the substrate in the battery industry. Coating width and lateral position must be measured with a measuring accuracy of down to +/- 0.05 mm. The coating must be positioned in the same place on both the top and bottom.

ApplicationThe position of the coating is measured immediately after the first and second coating application. The opaque substrate (aluminum or copper) is acquired using the incident light principle. The cameras are to be positioned at an angle of approx. 90° and the light transmitter at an angle of approx. 45° in relati-on to the surface of the web. A camera is to be provided for each coating strip to obtain optimal measuring accuracy.

Surface weight measurement ELTIMFunctionBased on ultrasound technology, the surface weight of a moving web is accurately determi-ned online and contactlessly. The detection of the surface weight is performed with the aid of a traversing sensor head across the entire width of the web. In addition, the thickness can also be calculated by entering the material-specific density.

Area of useSurface weight measurement systems ELTIM are used predominantly in flat extrusion and coating systems.

ApplicationA surface weight measurement system is normally installed after a process for quality control. In coating systems, in order to calcu-late the correct material application it is ne-cessary to measure both the substrate before the process and the coated product after the process.
