Corner bead roller apparatus

Abstract

There is provided a corner bead roller apparatus according to one aspect. The corner bead roller apparatus includes an elongate mount, a first one or more roller assemblies and a second one or more roller assemblies angularly spaced from the first one or more roller assemblies. Each roller assembly includes a shaft coupled to the elongate mount and a roller rotatably coupled to the shaft, with the roller continuously tapers from a distal end thereof to a proximal end thereof.According to another aspect, each roller rotatably couples to and is axially moveable at least in part relative to the shaft thereof.According to an additional aspect, each roller includes an inner portion rotatably coupled to the shaft and an outer portion coupled to and extending about the inner portion thereof, with distal ends of the outer and inner portion aligning flush with each other.

         4 . A corner bead roller apparatus according to  claim 1  wherein each said roller includes an outer wall extending from the proximal end thereof to the distal end thereof, with each said outer wall being frustoconical in shape. 
     
     
         5 . A corner bead roller apparatus according to  claim 1 , including a plurality of shafts coupled to and extending outwards from the elongate mount, with the rollers rotatably coupling to respective said shafts thereof and coupling to the elongate mount via the shafts. 
     
     
         6 . A corner bead roller apparatus according to  claim 5  wherein each said shaft extends along a longitudinal axis, wherein each said roller includes an outer wall extending from the proximal end thereof to the distal end thereof, and wherein for each said roller the outer wall thereof flares outwards at a constant angle relative to the longitudinal axis of the shaft to which the roller couples. 
     
     
         7 . A corner bead roller apparatus comprising:
 an elongate mount; and   a first one or more roller assemblies and a second one or more roller assemblies angularly spaced from the first one or more roller assemblies, each said roller assembly including a shaft coupled to and extending outwards from the elongate mount and including a roller rotatably coupled to and axially moveable at least in part relative to the shaft thereof.   
     
     
         8 . A corner bead roller apparatus according to  claim 7 , wherein for each said roller assembly the roller thereof is slidable relative to the shaft thereof. 
     
     
         9 . A corner bead roller apparatus according to  claim 7 , wherein each said roller assembly includes a pair of spaced-apart protrusions which extend radially outwards from the shaft thereof and between which the roller thereof is positioned and is moveable therebetween. 
     
     
         10 . A corner bead roller apparatus according to  claim 9 , wherein for each said roller assembly at least one said protrusion thereof is slidable relative to the shaft thereof. 
     
     
         11 . A corner bead roller apparatus according to  claim 9 , wherein for each said roller assembly at least one said protrusion thereof comprises a washer. 
     
     
         12 . A corner bead roller apparatus according to  claim 11 , wherein for each said roller assembly the washer thereof is slidable relative to the shaft thereof. 
     
     
         13 . A corner bead roller apparatus according to  claim 9 , wherein for each said roller assembly at least one said protrusion thereof comprises an enlarged end portion of the shaft thereof. 
     
     
         14 . A corner bead roller apparatus according to  claim 9 , wherein for each said roller assembly at least one said protrusion thereof comprises a flange coupled to and extending radially outwards from the shaft thereof. 
     
     
         15 . A corner bead roller apparatus according to  claim 14 , wherein for each said roller assembly the flange thereof selectively abuts a proximal end of the roller thereof. 
     
     
         16 . A corner bead roller apparatus according to  claim 14 , wherein for each said roller assembly the flange thereof extends radially outwards from a proximal end of the roller thereof. 
     
     
         17 . A corner bead roller apparatus according to  claim 7 , wherein for each said roller assembly the shaft thereof includes a first end portion that is threaded and via which the shaft couples to the elongate mount and wherein for each said roller assembly the shaft thereof includes an enlarged second end portion which selectively abuts the roller thereof. 
     
     
         18 . A corner bead roller apparatus comprising:
 an elongate mount; and   a first one or more roller assemblies and a second one or more roller assemblies angularly spaced from the first one or more roller assemblies, each said roller assembly including a shaft coupled to and extending outwards from the elongate mount, and a roller with an inner portion rotatably coupled to the shaft thereof and an outer portion coupled to and extending about the inner portion of the roller thereof, wherein the outer portions of the rollers are more compressible relative to the inner portions of the rollers, and wherein for each said roller the outer portion thereof and the inner portion thereof have distal ends which align flush with each other.
