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.
Claims12
A method of manufacturing thermoplastic adhesive dispensing tape comprising the steps of:
- (a) unrolling a flexible carrier strip from a first reel to expose a first release surface, said flexible carrier strip extending longitudinally, having a transverse width, and having a second release surface opposite the first release surface;
- (b) dispensing molten thermoplastic adhesive at periodic intervals on the unrolled flexible carrier strip to provide at least two separate portions of thermoplastic adhesive at transversely separated locations;
- (c) providing an indicator to separate the flexible carrier strip into multiple segments having at least one portion of thermoplastic adhesive;
- and
- (d) compressing the upper surface of the flexible carrier strip against a non-stick surface to compress the dispensed molten thermoplastic adhesive into flat pads.
