Abstract
A machine for wrapping a pipe with tape or another strip of material includes a frame defined by a pair of spaced apart V-shaped ends, which are interconnected at their vertices by a roll of tape, the ends having wheels and straddling a pipe so that the tape can be unwound onto the pipe when the frame is rotated around the pipe, and one of the frame ends is rotatable relative to the other end so that the wheels on one end can be moved out of alignment with the wheels on the other end to change the path of travel of the frame on the pipe from circular to helical or to lengthen the helix.
Claims4
A machine for wrapping a pipe with a strip of material comprising a frame, said frame including a pair of substantially inverted V-shaped ends for straddling a pipe to be wrapped;
- bracket means including axle means located substantially at the vertex of each said end for rotatably supporting a roll of said material between said ends;
- roller means rotatably mounted on each arm of each said end for movably supporting said frame on a pipe to be wrapped;
- and adjustment means on one said end for moving one end relative to the other frame end, so that the rollers on one end are out of alignment with the rollers on the other frame end, whereby when the frame is moved on a pipe with the free end of the material attached to the pipe, the frame and the tape follow a helical path of travel along the pipe.
