Adjusting the Lower Wire Tube (Figure 8)
In order to ensure the proper feeding of wire through the G8 Stitcher Head ensuring its continuous
operation, it is important that the wire leaves the Lower Wire Tube Assembly (G20199A) in straight
horizontal line and enters the Cutter Block Assembly without assistance. Wire straightness is the
single biggest factor for ensuring good stitches and stitcher head reliability. Although the position of
the Lower Wire Tube is set at the factory, transportation can cause the factory settings to change and
every roll of wire has varying degrees of twist which make it necessary for the user to properly
straighten the wire prior to production as well as during normal production. Follow the steps for
aligning the Lower Wire Tube listed below.
If the wire coming out of the Lower Wire Tube hits
the side of the Wire Straightener Roller (G20208B)
instead of passing over it, the groove in the Wire
Tube has to be aligned with the groove in the Roller
by adjusting the position of the Lower Wire Tube.
Turn the Wire Straightener Eccentric (G20206) so
that the maximum amount of space is allowed for the
wire between the two (2) Wire Straightener Rollers.
Loosen, but do not remove, the two (2) Socket Head
Set Screws (G20191) in the Cutter Block Assembly.
One adjustment that can be made is to move the
Tube up or down. Make sure the Wire Tube is close
enough to the Wire Straightener Roller to ensure
continuous feeding of the wire, but not pressed
against the Roller, which will stop the wire
completely. Leaving a 0.010" (.025mm) space
between the Tube and the Wire Straightener Roller is
a good gauge. Tighten the two (2) Set Screws at this
point and double check the space between the Tube and the Roller before proceeding.
The other adjustment that can be made is to tilt the Wire Tube toward or away from the Cutter Block.
If the wire feeding out of the Cutter Block is curving up then tilt the Wire Tube toward the Cutter
Block Assembly. If the wire is curving down then tilt the Wire Tube away from the Cutter Block
Assembly. Before tightening the Set Screws, verify that there is still at least a 0.010” clearance
between the Lower Wire Tube and the Wire Straightener Roller.
Once the wire is successfully feeding between the two (2) Wire Straightener Rollers, turn the Feed
Release Handle (G20119) to the off position, remove the Middle Wire Tube (G20144A) enough to cut
the wire as it exits from between the Large Feed Gear Assembly (G20110A) and the Small Feed Gear
(G20112) and remove the wire. Turn the Feed Release Handle to the on position again and activate
the stitcher head until the wire feeds out of the Lower Wire Tube. Make sure that the wire feeds
between the Wire Straightener Rollers without assistance, if not, make adjustments to the Lower Wire
Tube until it does.
