Abstract

A polypropylene injection molded staple, which are melted together by a heating process in strips, for use in a mechanical staple-driving machine. The individual staples have sufficient strength and flexibility to secure plastic tubing to polystyrene insulation for radiant floor and snow melt heating systems.

Claims

1. A staple formed from a resilient plastic material and adapted to be used in a mechanical staple-driving machine for fastening plastic tubing to polystyrene insulation for radiant floor and snow melt heat systems, said staple packs comprising of;

(a) a backspan with a 0.375 internal radius; and

(b) two prongs integrally connected and extending perpendicular from said backspan in substantially parallel relationship to each other, each prong having a shaft portion with one barb, and a rounded tip portion with two barbs; and

(c) melted together on the upper outside radius by a heating process to keep flexibility upward and rigidity sideways.
