CUT BEFORE EDGING MACHINE
UPPER THREAD DRAW-OFF
AND TENSION DETAILS
Keep Tension tight enough to break the
upper thread at the last stitch, and to prevent
thread from being drawn from the source of
supply through the needle as the gartment is
removed from the machine. Make sure that
Lever releases Tension when machine
starts sewing, so that only Tension will be
effective during the sewing cycle.
The required length of Starting Thread at
is provided by the movement of Upper
Thread draw- off Tension . This Tension
should swing in the direction indicated by
arrow X immediately after the machine
starts, and in the direction of arrow Y when
the machine is at the far end of its travel.
ADJUSTMENT OF UPPER
THREAD DRAW-OFF

Thread at proceed as follows:

stopping position. Loosen screws and
rotate Cam to the point where Pin is at
the very top of the Cam rise at as shown
Fig. 1. Then tighten screws and

OPERATION OF UNDER THREAD
GRABBER
Thread Grabber , Fig. 2, should be positioned to
catch and lightly hold the Under Thread against the
back beveled edge of the Throat Plate as the machine
stops.
A slight tug on the garment as it is removed from the
machine will cause the thread to break at the knot of
the last stitch. A sufficient end of the thread will
remain held by the Grabber above the Throat Plate as
shown in Detail A to start the next sewing cycle.
Important: In order for the thread Grabber to
swing through its full arc end hold the thread as shown
Detail A, the machine must be adjusted to stop in its
extreme forward position. For instructions to obtain
this adjustment refer to Sheet 19, Fig. 1.
With the machine in Stop Position as described above,
make sure that Lever is engaged in the notch of
Latch with no more than paper thickness clearance
existing at point . To obtain this clearence loosen
screw and turn Eccentric as required. Then
tighten Screw securely.
