Abstract

613,473. Coiling. LOCK JOINT PIPE CO. May 14, 1946, No. 14518. Convention date, Oct. 15, 1945. [Class 83 (iv)] In a method of applying a tensioned line, e.g. wire &c., winding to an object such as a pipe core, a loop 19 is formed in the wire between its anchoring point 20 at one end of the object, and a few snubbing turns 17 temporarily applied to the core. A weighted sheave 18 is received in the loop 19 and applies balanced torques to the object so that although the wire is greatly tensioned the power required to rotate the object is low. The sheave 18 and a wire guide 16 are traversed longitudinally as the core is rotated to apply the main winding 29. The movement is stopped when the snubbing turns 17 run on to a mandrel or chuck face at the other end of the pipe and the wire is anchored to the pipe at this end. Specification 582,553 is referred to.
