From: Patent Tactics, George Brock-Nannestad
I can't believe I am even contributing to this long thread about a s......
bit of plastic. However, I have my bit of experience as well.
For 3" reels, which were used for 8mm film (single-8 to those who are an in-
between age) as well as for quarter-inch magnetic tape, they used to deliver
rubber bands with a tab to hold the pancake. Worked fine, and I have yet to
see one that has deteriorated. They must have been made of synthetic rubber.
Any tape that has a latex (natural rubber) component to the sticky stuff will
harden. Gaffa (gaffer's) tape is only a glorified Duck (duct) tape with a
close-weave fabric that tears easily, but both are latex-gummy. One quality
of a tape is tackiness, another is adhesion. Editing tape needs very low
tackiness and high adhesion. Hold-down tape is only really good if you fold
the end to create a tab.
Have we milked this subject dry now?
