Abstract
An adhesive tape for use with high-speed webs which provides for adherence between two surfaces before allowing the tape to separate along a specific interface between two non-adhesive layers. The separation of tape along the specific interface results in the absence of any exposed adhesive surfaces and provides for improved performance in a variety of uses.
Claims14
A tape for use with high-speed web reels, the tape comprising:
- a first adhesive having top and bottom surfaces;
- a breakaway-coating covering the top surface;
- a release-coating affixed to the breakaway-coating along an interface;
- a substrate having first and second surfaces, the second surface secured to the release-coating;
- and
- a second adhesive having upper and lower surfaces;
- whereby the tape is provided for holding a reel of a web onto a core, the web having an innermost layer with an inner surface and the core having an outer surface, and wherein the bottom surface of the first adhesive can be adhered to the outer surface of the core and the upper surface of the second adhesive can be adhered to the inner surface of the innermost layer so that a force pulling the web from the core causes the tape to separate along the interface of the release-coating and breakaway-coating so that no adhesive is exposed after separation.
A method of splicing a reel of a new web to a reel of a depleted web which is rotating at a high speed, the new web having an outer layer with an inner surface and an opposite surface and a distal end and an inner layer with an outer surface, comprising the steps of:
- utilizing a tape for use with high-speed web reels, the tape comprising:
- a first adhesive having top and bottom surfaces;
- a breakaway-coating covering the top surface;
- a release-coating affixed to the breakaway-coating along an interface;
- a substrate having first and second surfaces, the second surface secured to the release-coating;
- a second adhesive having upper and lower surfaces, the lower surface adhered to the first surface;
- and
- a release-liner adhering to the upper surface;
- adhering the bottom surface to the outer surface;
- removing the release-liner;
- adhering the upper surface to the inner surface;
- positioning holding tape over the distal end to keep the outer layer from unintentionally separating from the inner layer;
- providing a adhering element on the opposite surface;
- and
- contacting the depleted web to the new web so that the depleted web adheres to the adhering element and causes the tape to split along the interface such that no adhesive surface is exposed.
A method of releasably adhering a reel of a web to a core, the web having an innermost layer with an inner surface and the core having a outer surface, comprising the steps of:
- utilizing a tape for use with high-speed web reels, the tape comprising:
- a first adhesive having top and bottom surfaces;
- a breakaway-coating covering the top surface;
- a release-coating affixed to the breakaway-coating along an interface;
- a substrate having first and second surfaces, the second surface secured to the release-coating;
- a second adhesive having upper and lower surfaces, the lower surface adhered to the first surface;
- and
- a release-liner adhering to the upper surface;
- adhering the bottom surface to the outer surface of the core;
- removing the release-liner;
- and
- adhering the upper surface to the inner surface of the innermost layer;
- whereby the tape splits along the interface when the reel is depleted and the web is pulled from the core.
