Stitching Tolerance
July 4, 2022
Dave asks,
We have an old foot pedal stitcher we manually stitch boxes with. Is there a standard spacing between staples that we must maintain?
Dave, this was a new one for me. Took a bit of research using a number of resources, but this should address your question.
Singlewall: Starting and ending staples shall be 1 to 1½ inches from the flap score lines. Intermediate staples shall be spaced no more than 2½ inches apart.
Doublewall: Starting and ending staples shall be double stitched no more than 1 to 1½ inches from the flap score lines. Intermediate staples shall be spaced no more than 2½ inches apart. For products weighting 100 lbs. or more spacing of intermediate staples shall be reduced to 1 to 1½ inches apart.
Triplewall: Starting and ending staples shall be double stitched no more than 1 to 1½ inches from the flap score lines. Intermediate staples shall be double stitched and spaced no more than 1 to 1½ inches apart.
