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.

A thermoplastic adhesive dispensing tape comprising:
- a flexible carrier tape having a transverse width and a longitudinal length including a plurality of contiguous longitudinal segments extending along the entire longitudinal length of said carrier tape, each of said longitudinal segments extending the entire transverse width of said flexible carrier tape, said flexible carrier tape also having opposed first and second release surfaces;
- and
- a plurality of thermoplastic hot melt adhesive segments arrayed non-contiguously on said first release surface of said carrier tape along the longitudinal length of said carrier tape;
- wherein only a single one of said adhesive segments is disposed within each of said longitudinal segments on said first release surface of said carrier tape;
- and
- wherein each of said adhesive segments is individually exposable to an abutting planar surface when said carrier tape is transversely flexed.
