Abstract
Hot melt thermoplastic adhesive is predeposited on a carrier strip having front and back release surfaces. The carrier strip is rolled into a coil compressing the thermoplastic hot melt into disks which may later be removed for use. The disks are spaced so that the carrier strip may be deformed to expose a single disk to a planar surface permitting simplified dispensing of the disks.
Claims6
A thermoplastic adhesive dispensing tape consisting of:
- a flexible carrier tape extending longitudinally, having a transverse width, and having opposed first and second release surfaces;
- and
- a plurality of thermoplastic hot melt, adhesive dots arrayed longitudinally along the first release surface, each separated from other dots by a gap extending transversely across the entire carrier tape;
- wherein the thermoplastic adhesive dots are arranged in only a single line transversely centered on the release surface;
- whereby the carrier tape may be transversely flexed to expose a single adhesive dot to an abutting planar surface;
- wherein the adhesive dots are substantially identical.
