Drywall Trim Autofolder, Mastic Applicator and Cutter

Abstract

A drywall trim application device that can hold a large role of drywall flex corner trim material and, as the material is being dispensed, pre-crease or form the material for use on an inside or outside corner, or any angle within the range of the trim material, apply a mastic material (drywall mud, adhesive or any other bonding medium) to the flex trim material, and cut the material at any desired length automatically. Measurements may be either input by hand or downloaded from an electronic measurement tool into this device. This invention can generally store multiple measurements such as length and angles, measure the length of flex trim material as it is dispensed from the device, crease the material, apply predetermined amount of mastic, and automatically cut the flex trim material to each length previously input.

         3 . The drywall trim application device of  claim 1  wherein said drywall trim is constructed of a rigid or semi rigid core with a outer surface prepared to accept a mastic, texture, paint or other finishing material. 
     
     
         4 . The drywall trim application device of  claim 1  wherein said drywall trim is constructed of a rigid or semi rigid core with a inner surface prepared to accept a bonding medium for adhering to the drywall corner. 
     
     
         5 . The drywall trim application device of  claim 1  wherein said device can apply drywall joint compound, adhesives, or a medium that activates an adhesive already present on the surface of the drywall trim. 
     
     
         6 . The drywall trim application device of  claim 1  wherein said device can store multiple measurements and angles. 
     
     
         7 . The drywall trim application device of  claim 1  wherein said device can dispense a piece of folded, coated and measured trim material automatically or on command. 
     
     
         8 . The drywall trim application device of  claim 1  wherein said device can dispense a piece of folded, coated and measured trim material in a manual mode. 
     
     
         9 . The drywall trim application device of  claim 1  wherein said trim material is has a metal core. 
     
     
         10 . The drywall trim application device of  claim 1  wherein said trim material is has a plastic core. 
     
     
         11 . A drywall trim application device comprising: a drywall trim roll; a means for feeding drywall trim from said trim roll; a folder mechanism; a mastic applicator; a cutter; wherein said drywall trim is fed into said folder mechanism, said mastic applicator and said cutter so that said drywall trim is folded to a predetermined angle longitudinally, coated with mastic and cut to a predetermined length and wherein said device can apply drywall joint compound, adhesives, or a medium that activates an adhesive already present on the surface of the drywall trim. 
     
     
         12 . The drywall trim application device of  claim 11  wherein said device can dispense a piece of folded, coated and measured trim material automatically or on command. 
     
     
         13 . The drywall trim application device of  claim 11  wherein said device can store multiple measurements and angles. 
     
     
         14 . The drywall trim application device of  claim 13  wherein said device can dispense a piece of folded, coated and measured trim material automatically or on command. 
     
     
         15 . The drywall trim application device of  claim 11  wherein said drywall trim is constructed of a rigid or semi rigid core with an outer surface prepared to accept a mastic, texture, paint or other finishing material. 
     
     
         16 . The drywall trim application device of  claim 11  wherein said drywall trim is constructed of a rigid or semi rigid core with an inner surface prepared to accept a bonding medium for adhering to the drywall corner. 
     
     
         17 . The drywall trim application device of  claim 15  wherein said drywall trim is constructed of a rigid or semi rigid core with an inner surface prepared to accept a bonding medium for adhering to the drywall corner. 
     
     
         18 . The drywall trim application device of  claim 12  wherein said drywall trim is constructed of a rigid or semi rigid core with an outer surface prepared to accept a mastic, texture, paint or other finishing material. 
     
     
         19 . The drywall trim application device of  claim 18  wherein said drywall trim is constructed of a rigid or semi rigid core with an inner surface prepared to accept a bonding medium for adhering to the drywall corner.
