ABSTRACT:
Pipe wrapping apparatus of the so-called hand-wrapping type, having a rotating ring structure which carries spindle apparatuses, each carrying a roll of pipe wrapping tape. The apparatus includes take up spindles for accumulation of the backing stripped from tapes which have backing, and includes brake devices for controlling the tension at which the tape is wound onto the pipe. While the apparatus is of the so-called hand-wrapping type, it may be power driven. The apparatus also provides for applying a coat of primer or other precoating material onto the pipe prior to the application of the tape. A notable feature of the invention is the provision of self-balancing spindles through the use of which the tape is consistently applied to the pipe without wrinkles or other misalignments of the tape and with uniform overlap of courses.
