Specifications

The overall length of the stitch is controlled by the amount of wire that is drawn from the spool

after each stroke of the stitcher machine. To change the overall length of the stitch, the position of

the Feed Rack (G20527) has to be changed within the Stitcher Head. (Figure 10).

First, make sure the wire feeding is off by turning

the Feed Release Cam (G20519) horizontally so that

the Small Feed Gear (G20512A) on the Feed Lever

(G20532B) is disengaged from the Large Feed Gear

Assembly (G20510A). The wire draw is set at the

factory but if adjustments have to be made for

specific stitcher equipment, turn the Feed Rack

Adjustment Knob (G20173) clockwise to move the

Rack up and counter-clockwise to move the Rack

down.

As the thickness of work being stitched increases,

the length of wire required must also increase. The

longer the length of wire required, the further up the

Feed Rack has to be in comparison to the Feed Slide.

Start by calibrating the G20 Head at a two-sheet

capacity. The overall length of wire is correct when

the gap between the staple legs allows only the edge

of a fingernail to pass between them. If your stitcher machine has a built-in stroke adjustment, no

further adjustments will be required, even when changing stitching capacities. If the stitcher has no

automatic stroke adjustment then the length of wire has to be adjustment manually every time the

capacity changes.

In order to increase the wire draw or lengthen the legs of the stitch and decrease the gap size, turn

the Feed Release Cam (G20519) to the off position and the Feed Rack Adjustment Knob clockwise.

Inversely, to decrease the wire draw or shorten the legs of the stitch and increase the gap size, turn

the Feed Rack Adjustment Knob counter-clockwise.
