What Causes Loose Cores & How to Avoid Them

Posted by Phillip Shows on Dec 4, 2017 11:03:00 AM

What is a Loose Core?

A condition brought about primarily in pad-wound tapes where a reduction in moisture from within the cardboard core causes the wound material to become unstable and/or loose.  This looseness is evident in the surrounding layers of tape near to the core and could create an unsteadiness in the pad.  In extreme cases, the core may tend to slide completely out from the center of the pad.  With no tension against the core, some layers further up the pad diameter could also become loose during handling.

Can SLICKTAPE® solve your tape forming issues?

Posted by Phillip Shows on Oct 30, 2017 10:12:00 AM

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.
