Abstract
A machine wraps pipe as it travels along a substantially linear path between a feeder reel from which the pipe is unwound to a take up reel onto which the pipe is rewound. A pipe wrap assembly for wrapping one or more layers of tape about the pipe is rotatably mounted on a carriage. A mechanism mounted on the carriage and engaged with the pipe drives the carriage along the pipe as the pipe travels from reel-to-reel. As the carriage is driven along the pipe, the tape is spirally applied to the pipe by the pipe wrap assembly. The carriage is supported for lateral horizontal movement in response to variation in the unwind and rewind points on the feeder and take-up reels. The carriage is also supported for longitudinal horizontal movement in response to changes in the rate of travel of the pipe relative to the rate of travel of the carriage. A drive control mechanism permits variation in the rate of travel of the carriage to compensate for variations in the rate of travel of the pipe between the reels to maintain the carriage in generally constant position as the pipe travels between the feeder and take up reels. The controller may be manually operated in response to visual observations by the operator or may be automatically operated in response to sensor or computer data to determine the longitudinal position of the carriage.
