Abstract
A method for anchoring a metal tape-cutting blade to a thermoplastic resin frame of a tape dispenser. The plate is pierced to produce a plurality of plate portions projecting around an opening. The projections are positioned against the frame. Ultrasonics are used to locally heat the frame while the projections are pressed into it, whereupon a portion of the thermoplastic frame material flows into the opening between the projections and upon solidification holds the blade in place.
