Spiral zipper chain cutting tool "Gappy"

Spiral zipper chain cutting tool (Gapping Tool)
If you often shorten separable (open end) zippers, this tool removes completely the spiral chain and its sewing thread from both zipper tapes of sewn spiral zippers in seconds. As a result you obtain a neat top tape extension, which allows you to process further the zipper more easily. Application video

The tool is only available for 4 to 6.7 mm wide spiral chains. Each chain width requires a separate tool. The tool is not suitable for woven spiral zippers.

The name "Gappy" comes from the gapping process in the industrial zipper production. (Privacy notice: The video at the following link opens on the YouTube website.) external A gapping tool punches gaps in the endless zipper chain, before it is cut into finished lengths. Our "Gappy" tool does not punch gaps, but it has the same purpose: It removes the zipper chain from the zipper tape.
