In this video, Philip Shows addresses common slitting questions: where does splicing take place during the process, how does Chase maintain good slit edge quality, and what are Chase’s slit width tolerances?
Most cable manufacturers rely on forming tools to properly fold and align shielding tapes with the precision necessary to meet strict cable performance criteria. As you can imagine, running a foil tape across a metal forming tool creates friction that abrades both the tape and tooling itself. Any debris generated during the process, either from the tape or from its contact with the forming tool, eventually accumulates in the tooling causing unwanted cable defects and/or tape breaks due to space limitations. The typical practice in the wire and cable industry is to attempt to minimize this type of scuffing by directly lubricating either the tooling or the tape with oiling devices.
