摘要： Apparatus is disclosed for wrapping strips of sheet material in tape form around a pipe or conduit having a generally circular cross-sectional external shape. The apparatus includes a frame assembly having a pair of annular frame members connected by a desired number of frame cross members for structural support, each frame member being hinged to open around a conduit; a guide roller assembly including a plurality of drive wheels angularly adjustable with respect to the conduit being wrapped to vary the angle of the drive rollers with respect to the conduit being wrapped for varying the amount of sheet material overlap; a plurality of support rollers connected to the frame; a sheet material feeding assembly; a sheet material tensioning assembly; and a tape backing material take off assembly.
