The selected work space works on production offelled seams.

This type of seam is commonly seen as the inseamin denims.

The Commonly used machine for this type of seamis Feed of the arm machine.

A single operator is required for the process.

Pick up the first piece

Place it through the folder under the pressurefoot.

Pick the second piece

Place it through the folder under the pressurefoot.

Hold both the pieces with hand applyingpressure tangentially to let the fabric pieces

pass through the folder. Stitch

Assembly tasks have many differentcomponents that

Must be considered in an ergonomicassessment including:

Supply and removal of garments,

Sewing table,

Chair,


11/42

Floor surface,

Foot pedals,

Lighting,

Hand tools and

Work organization.

We will look at ergonomic problems andsolutions for

Each of these components.

Table Dimensions length*width*height = 25.5*20.5*29.5

Chair Dimensions length*width*height = 16*12*19

Gap between two consecutive machines = 21 All Dimensions are in inches


21/42

Basic Considerations - Do the employee have sufficient strenght to

perform the task?

Do the employee report significant musclefatigue performing the work?

Do the employee become physicallyexhausted performing the work?


22/42

Are there any work-related musculoskeletaldisorders?

Are there psychomotor and cognitivedemands that may cause accidents?

Do the workstation layout cause limits onmotion, excessive motion or postural fatigue?

Are there environmental conditions, such asheat, cold, vibration, noise or inadequateillumination, that may reduce performance?

Checklist for elements of ERGONOMICS.

the muscles

Tendinitisinflammation of a tendon (e.g.,

shoulder tendinitis, tennis elbow) Tenosynovitisinflammation of a tendon and its

sheath (e.g., in the wrists,hands, or fingers)

Carpal tunnel syndromeswelling and entrapment

of the median nerve in the wrist

Thoracic outlet syndromesqueezing of the nervesand blood vessels between the neck and shoulder.

Hand-arm vibration syndromedamage to blood

vessels and nerves in the hands and arms. Degenerated, bulging, or ruptured (herniated) disks

in the neck or back

Sciaticabulging or ruptured disks in the lower

back causing lower back pain that also extends tothe legs and feet

Degenerative or osteoarthritiswear and tear onthe spine, joints, vertebrae, and disks, associated

with long-term physical loads on spinal structures


37/42


38/42

The dimensions of the sewing table thatshould be considered are the:

Height, size, shape, (adjustible)

Tilt (tilted 10 to 25 towards the operator)

And leg room.


39/42

The best chairs have these features: A stable 5-point base of support;

Firm cushioning on the backrest and seatpan;

The seat can be adjusted in height and tiltquickly and easily;

The seat does not have a hump on the front

edge;


40/42

The backrest can be adjusted in height andfrom front to back;

The seat pan is large enough to support theoperator but small enough so that he or shecan use the backrest;

The backrest does not interfere with the

movement of the shoulder blades or arms; The chair can swivel when operators have to

turn sideways frequently; and

The chair has castors only where appropriate,and not where it makes operators slide awayfrom their workstation.


41/42

Use proper tools Keep repetitive motions to a minimum

Avoid awkward postures

Get proper rest
