METHOD AND DEVICE FOR PIPE COIL-WINDING AND FOR WRAPPING OF SAID COIL Russian patent published in 2015 - IPC B65B11/04 B65B25/24 B65H54/58 

FIELD: process engineering.

SUBSTANCE: this method is implemented with the help of appropriate device. Said device comprises translating structure supporting the drum running about lengthwise axis, device for pipe feed to said drum and wrapping paper feeder. Besides, it comprises two aligned discs, distal and proximal and arranged in opposition for limitation of coil sides in lengthwise direction. Note here that said structure is displaced axially to make said drum be located axially closer to distal disc to actuate pipe feeder and to start winding. Pipe is cut at reaching the programmed coil diameter to drive the wrapping paper feeder. Film is secured to the drum to start film winding on formed oil so that its front surface is covered. At winding, film feeder is shifted in both directions of lengthwise axis from one end to another relative to coil. Note here that discs for limitation of the coil and film sides in lengthwise direction are locked relative to running run while the surface of said discs have at least one interval in zone whereat film enters inside said discs. Said two opposite ends of film feeder lengthwise displacement allow said film extend beyond coil sides. Proposed device incorporates structural components specified in above describe process.

EFFECT: simplified wrapping after coiling.
