In order to ensure the stitches are loaded, driven and clinched properly in addition to ensuring
continuous operation of the G8 style heads, it is important that the wire leaves the Cutter Block
Assembly (G20197A) in straight horizontal line. Wire straightness is the single biggest factor for
ensuring good stitches and stitcher head reliability. Although straightness is set at the factory, 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
straightening wire listed below.
Horizontal Adjustment
Slide the Wire Holder Retaining Spring (G20183)
over to the side and remove the Wire Holder Assembly
(G20559BA or G20301A) from the Stitcher Head.
Make sure the Small and Large Feed Gears are
engaged. Activate the stitcher and observe the feeding
of the wire from the Cutter Block Assembly and take
note of the direction the wire is moving. Use a slotted
head screwdriver in the Wire Straightener Eccentric
(G20206) on the Cutter Block to adjust the wire. If the
wire is feeding upwards, turn the Wire Straightener
Eccentric clockwise. If the wire is feeding downward,
turn the Eccentric counter-clockwise.
Front-to-Back Adjustment
If the Left or Right Wire Guide Bars (G20141 or
G20142) are not properly positioned, the wire will rub
against them as it exits the Cutter Block. Look at the
G8 Head from the side past both the Right and Left Wire Guide Bars. Make sure there is a clear view
of the opening in the Fixed Wire Cutter (G20200) from the side of the G8 Head. If there is not, loosen
the Flat Head Machine Screws (G20215) securing the Wire Guide Bars to the Feed Gear Bracket
Assembly (G20136A) and move them out of the path of the wire. Tighten the Screws after making
sure the Wire Guide Bars are even with each other. Replace the Wire Holder
and re-engage the Wire Holder Retaining Spring. Load a piece of wire into
the Wire Holder. Using a mirror, check to make sure the wire in the Wire
Holder is lined up with the grooves in the Bender Bar Assembly
(G20147BA, G20347BA or G20357BA). If it is not, loosen the Socket
Head Set Screw (G20273) in the front of the Wire Holder and the Hex Nut
(G20226) securing the Wire Holder Adjustment Screw (G20265). Turn the
Adjustment Screw until the wire is aligned with the grooves in the Bender
Bar. Tighten the Hex Nut and Set Screw to secure this setting.
Remove the wire in the Wire Holder and load another piece in the Stitcher Head. Verify that the
setting established is accurate by checking this piece of wire with the mirror.
