GENERAL INFORMATION

A. INTRODUCTION
The air Operated Underbed Trimmer contains a trimming system that cuts both the
needle and bobbin threads simultaneously. A movable and a stationary blade, mounted
on the throat plate are used in combination to pick up and cut the threads.
Solid state electronics are used to sense the position of the needle and to trigger the
trimming mechanism at the proper time as well as to control footlifting and backtacking
operations.
B. APPLICATION
The underbed Trimmer/Positioner enables the operator to automatically control the
position of the needle in or out of the work, thereby eliminating the need for hand position-
ing. In addition, the top and bottom threads are automatically cut beneath the throat
plate after positioning. This eliminates the need for hand trimming.
