Abstract
Abstract An applicator is disclosed for applying pieces of tape having a backing on one surface of which is a coating of a heat-activatable adhesive. The tape backing may be a fibrous tape as in hook and loop-fastening tape. The applicator utilizes an applicating pad having a surface which engages the backing opposite the adhesive surface. The pad supports the tape such that the same may be moved into contact with a heater and then moved to apply the tape to a receptor surface. The pad serves to uniformly affix the tape to the surface and force the backing and adhesive onto the surface to which the tape is to be applied. The tape may be applied to the pad and then cut to lengths or predetermined lengths of tape may be placed onto the brush.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
187 words
A tape applicator for applying a length of material coated with a heat-activatable adhesive to a receptor surface, said applicator comprising movable support pad means for supporting a length of said material, means for moving said pad means from a first receiving position to a second applying position to apply said length of material to the receptor surface, heater block means for making wiping contact with the adhesive-coated surface of said length of material supported on said pad means for activating said adhesive before the length of material is placed into contact with said receptor surface, said heater block means comprising a bar of metal having a longitudinal axis and having a bore disposed parallel with said axis, a heating unit disposed within said bore which is thermostatically controlled to maintain a high surface temperature on said bar of metal, and spring means supporting said bar of metal for urging the same toward said pad means during wiping contact between said block means and the adhesive of a length of material on said pad means to afford intimate contact between said bar of metal and said adhesive.
