Tips and Tricks for Your Stitching Job
By Keith Voigt // July 30, 2020
A chrome finish stitching wire made of galvanized metal wire is often coated with a friction-reducing additive that ensures no flaking or peeling for a seamless binding. This additive also helps yield a properly forming wire that can be bent into the ‘staple’ shape. Some machines can’t handle all types of wire, so be certain to make sure you are using the correct type wire for your precipice stitcher. If unsure, check your machine user manual or contact a tech team so they can help you find your compatible wires.
Tensile refers to the pull required to break the wire from the spool. Tensile is measured in PSI (pounds per square inch), and is a good indicator of the quality of the wire. High-quality wire generally has a higher tensile but stays within the range of 130,000-165,000 PSI. Below this range and the wire may be too soft and not properly formed into a stitch. Above this range and the wire may damage your machine or snap when forming to the ‘staple’.
Helix refers to the curve of the wire as it is unwound from the spool. A curve is often caused by the round-shaped spool the wire has been wrapped around, this is the Cast. The Camber is the axial component of the helix and is measured at the ends of the free-handing wire. The importance of these components is that the ratio between the camber and cast should be a large cast and small camber. This ratio will lead to a smoother running stitching machine.
Finally, the path of your stitching wire is crucial. An incorrect path could lead to catching and chipping of your wire as well as a prematurely worn out blade along with other parts of your stitcher. To ensure a clean path, make sure there are no flat spots on your guides and that your felt pad wiping system is clean.
