DEVICE FOR PIPE MANUFACTURING FROM COMPOSITE-FIBER MATERIALS AND METHOD OF PIPE MANUFACTURING FROM COMPOSITE-FIBER MATERIALS Russian patent published in 2008 - IPC B29D23/00 B29C53/56 

FIELD: technological processes.

SUBSTANCE: device for pipe manufacturing from composite-fiber materials consists of self-feeding holder, which consists of sectors, packers of transverse and longitudinal threads, support for pipe coming off the holder, polymer-making furnaces, which are installed along holder axis, circular template. Self-feeding holder, circular template, swivels of longitudinal threads packers are equipped with independent drives, which are connected with automatic system of control and equipped with rotation speed detectors. Method of pipe manufacturing from composite-fiber materials includes longitudinal and transverse winding on sectors of self-feeding holder of composite-fiber material that is soaked with binder, subsequent polymerisation of formed pipe layers, continuous pipe descent from holder. In the process of winding holder rotation speeds are changed, as well as speeds of circular template rotation, swivels of longitudinal threads packers rotation, pipe thickness is measured after winding of external layer from composite-fiber material and after final polymerisation. Then with the help of automatic control system rotation speeds of holder, circular template and swivels of longitudinal threads packers rotation are regulated.

EFFECT: increase of quality of reinforced pipes at the account of its thickness regulation in the process of winding.
