Punch Options
Self-locking Arrow (AP) Design - Single And Double Row Models Available
This style is shift locked in the same manner as the standard design, but will lock only in one direction. Therefore, with this design the leading edge must always be on top or always be on bottom in order to work.
Ideal for operations which are joining a wide range of materials. It can join thin materials with reduced risk of tabs breaking off of the strip. It can join materials up to .250″ thick.
This style of stitch has four point locking, providing approximately twice the strength of the standard design.
Self-locking Standard (WR) Design - Single And Double Row Models Available
Tension must be applied after making the stitch in order to shift lock it into position and prevent the material from coming apart. The stitch will lock if pulled from either direction.
Ideal for operations joining materials up to .1″ (2.5 mm) where the extra strength of the arrow design is not needed.
This style of stitch has two point locking, providing approximately twice the strength of the standard design.
Tapered "T" (TT) Design - Single, Double and Triple Row Models Available
The Tapered “T” punch has tapered sides to reduce the amount of scuffing and fines made during the shifting and locking of the stitch. It also has large engagement areas on the upper part of the T configuration. Larger overlap when the stitch is fully shifted is ideal for thin soft materials. The larger overlap resists bending and pulling apart when being wrapped around rollers.
Straight Sided (SS) Design - Single and Double Row Models Available
This design is not self-locking and requires that a precut strip or rod be inserted through the row of stitches to obtain a holding stitch.
