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.
Claims47
Pipe wrapping apparatus, comprising a tape spindle having a tubular spindle shaft, and a support shaft extending into said spindle shaft and pivotally connected to said spindle shaft at the center of the tape roll widths thereof whereby the angular position of said spindle shaft automatically adjusts in response to the tension of the tape as the tape is withdrawn from the tape roll to be wound onto a pipe.
Pipe wrapping apparatus, comprising carriage means supportable for movement along a pipe, support means surrounding the pipe supported by said carriage means for rotation around the pipe, and tape spindle means supported by said support means being pivotally mounted centrally of the tape spindle means axis whereby the angularity of said tape spindle means is automatically adjusted by the tension of the tape being wrapped onto the pipe so that the tape is wound flatly onto the pipe without wrinkling and distortion.
