Abstract:
1. A cassette for use in delivering a continuous length of filament, comprising: a spool having a flange with a recess that is rotatably mounted in a chamber of a substantially closed housing; a length of filament wound around the spool and having a free strand at an end thereof; a path from the chamber to an exit orifice, in which the filament strand is positioned; a floating tubular guide member through which the filament strand passes as it travels from the spool to the exit orifice; means for advancing the filament strand through the exit orifice; and a removable pin that is inserted into a recess in the cassette and the recess in the spool when the recesses are aligned to prevent the spool from rotating with respect to the cassette during transport of the cassette.
