Abstract
Improved method and apparatus for cutting or severing thin webs, especially adhesive transfer tapes, and other relatively thin materials which prevents or minimizes tearing.
Claims8
A method of handling a continuous, elongated web subject to possible tears upon being transversely severed, comprising:
- moving said web longitudinally along a path from a source through feed means and thence to engagement with a first rotating cylinder;
- rotating a cutting cylinder carrying at least one blade to bring said blade into contact with a portion of said web supported by said first cylinder thereby to sever said web along a cut line and to form discrete segments of said web on said first cylinder, and characterized in that said blade is moving faster than the feed rate of said web from said feed means, thereby inducing a tension spike in a section of said web between said feed means and said cut line during severing said web;
- and
- providing sufficient length in said section of said web between said feed means and said cut line to reduce the tensile stress in said section of said web between said feed means and said cut line to prevent tears in said web incident to severing of said web.
