Pipe joint wrapping machine

Claim 1

In a portable pipe wrapping machine for wrapping a pipe manually which comprises a pipe enveloping frame having a pipe receiving mouth, locking means mounted on said frame for disposition across said pipe receiving mouth to retain a pipe therein, and means mounted on said frame for rotatably supporting said frame concentrically on a pipe, the improvement which comprises a roll assembly that is mounted on said frame and that is adapted to receive and rotatably support a roll of wrapping material preformed with a separator sheet that is strippable therefrom and that in said roll separates adjoining plies of said wrapping material from each other with said roll in position for feeding wrapping material from said roll onto said pipe during rotation of said frame about said pipe, a sheet receiving assembly mounted in said frame that comprises a rotatable member presenting when rotated a moving surface adapted and positioned for receiving said separator sheet that is stripped from said wrapping material concomitantly with travel of said wrapping material from said roll to said pipe during rotation of said frame about said pipe, a wheel rotatably mounted in secured relation to said frame for frictional contact with said pipe and for rotation responsive to rotation of said frame about said pipe with said wheel in frictional contact therewith, means responsive to rotation of said wheel for rotating said rotatable member with movement of said travelling surface presented thereby at a rate sufficient to recieve thereon said protector sheet as it is stripped from said wrapping material during travel of said wrapping material from said roll to said pipe.
