ABSTRACT:
An apparatus and method for forming a hole in webbing constructed of thermoplastic material utilizes a clamping assembly for holding the webbing in a stationary condition for working thereon, a rotatable drilling tool having an elongated shank with a leading end and a flute spiraling along the shank from the leading end, and a burner for heating a portion of the drilling tool shank adjacent the leading end. The drilling tool is supported adjacent the clamping assembly for rotation of the tool about a rotation axis which corresponds with the longitudinal axis of the shank and for movement of the leading end of the tool along a linear path corresponding with the rotation axis into and out of the webbing held by the clamping assembly. After a portion of the drilling tool shank adjacent its leading end is heated to a temperature which is at lesate as great as the melting temperature of the thermoplastic material of the webbing, the leading end of the heated drilling tool is directed along the linear path of movement through the webbing as the tool is rotated about its rotation axis to form a hole in the webbing. The hole formed in the webbing is devoid of melt build-up or flash and readily accommodates the insertion of grommets or eyelets therethrough.
