US 7,624,782 B2 · Taper tool

Abstract

A taper tool for applying tape to a wall surface is provided. The taper tool may simultaneously advance tape and apply mastic to the advancing tape. The taper tool may include a jam clearing assembly for clearing tape jams occurring along the tape path. The taper tool may include a body for holding mastic and a taper head coupled to an end of the body. The taper head includes a housing defining an opening and a mastic ejection nozzle, both of which are in fluid communication with the body. The opening facilitates introduction of mastic into the body and the nozzle facilitates ejection of the mastic from the body onto the tape. The taper head also includes a valve positioned within the opening to control introduction of mastic into the body, and a cover plate removeably connected to the housing to cover both the opening and the nozzle.

Dependent claims

A taper tool comprising:

a body for holding a supply of mastic;
a spool assembly for supporting a spool of tape;
a drive roller positioned at an end of the taper tool, the tape being feedable from the spool of tape and at least partially around the drive roller to be applied to a wall surface;
an actuator supported by and moveable along the body;
a tape advancing assembly including a transfer member engageable with the drive roller, the tape advancing assembly coupled to the actuator and engageable with the tape to advance the tape toward the drive roller;
and
a mastic application assembly connected to the tape advancing assembly, coupled to the actuator, and operable to apply mastic to the tape;
wherein movement of the actuator moves the tape assembly to advance the tape toward the drive roller and actuates the mastic application assembly to rotate the drive roller via the transfer member to force mastic from the body and onto the advancing tape.
