In an industrial sewing operation there is likely to be a very diverse
assortment of manufacturing processes. I'll post only one for you,
followed by sage advise. If you require more detail please respond to me
directly.
JOB DESCRIPTION FOR FINISHING SEW
The finishing operation can be done in a sitting position or standing
position with the stock located to the operator's left. Machine height
depends on worker's preference. Acquiring the stock requires thirty
degrees of trunk rotation as well as partial shoulder flexion and
abduction and elbow extension. The final part of the operation involves
attaching two seperately designed pieces. This particular movement
involves a slight elbow extension with minimal to no effort. The other
part of the operation involves sewing the facing to the back of the
part. The right arm is in an abducted position holding the material with
a lateral grip under the left arm. The left hand is usually flat against
the material, however lateral gripping is occassionally necessary when
sewing around corners. The left wrist is usually radial deviated, when
sewing around corners wrist abduction is necessary. These movements
require slightly higher than moderate effort by the sewer. The sewing
machine is operated through planter and dorsi flexion on the foot pedal
which can be operated using the left or right foot. The finished piece
is discarded forwards requiring left elbow extension. A certain
percentage of the time is also given to walking to get stock and
material, changing thread, changing needles or performing tasks not
directly involved in the sewing process.
- It is most important to have the sewing machine properly set up. A
good mechanic can make all the difference in ergo matters. The feed-dogs
must be adjusted to diminish the act of feeding or pulling the material.
- much consideration must be given to proper stock location within the
sewers work environment.
- A lot of focus must also be placed on not only what type of seat is
utilized, but more importantly, the worker must understand the necessary
adjustments and settings in relation to body size.
- If it is a stand-up machine, it should have a proper ergo foot pedal
and pad in place.
Hope this helps. Unfortunately the information you need could literally
fill many books. We have experienced a very high rate of injury at our
plant.
