E. NEEDLE COOLER

Adjust the flow control for the desired air flow to cool the needle and keep the throat plate

knife clean.

F. FOLDER OPENER

Adjust folder opener mounting bracket for required amount of opening.

V. TRIMMER SEQUENCE OF OPERATION

A. UNDERBED TRIMMER

The operation of the underbed trimmer is as follows:

1. Needle positioner stops with the needle thread positioned between the 5 and 6 o'clock

position across the hook. The needle is used for the reference point or 12 o'clock

position.

2. The movable knife is extended into the needle loop and in position to pick up the

bobbin thread.

3. The needle positioner moves the takeup and needle to up position.

4. The tension release, the pulloff and wiper cylinders operate after the positioner

reaches to up position.

5. Then the movable knife is returned to cut both needle and bobbin threads.

B. TENSION RELEASE

The needle thread tension is released so that the thread puller can pull off enough

thread to start the next sewing operation.

C. NEEDLE THREAD WIPER

The needle thread wiper pulls the needle thread above the foot before it is raised. If the

thread is trapped under the foot a long tail will be left at the start of the next sewing

opera-tion.
