COILER DRUM MADE WITH POSSIBILITY OF WIDENING AND NARROWING Russian patent published in 2007 - IPC B21C47/30 

FIELD: equipment for coiling metallic belt.

SUBSTANCE: shaft of coiler drum has wedge surfaces engaging with joined surfaces of segment. Outer surface of segments forms circle for coiling belt. Segments may move relative to shaft in axial direction. In order to lubricate joined surfaces pipeline system is used; said system is connected with pump for lubricating material. Pump has control organ for realizing lubricant supply process. Pump is connected with unit for moving segments or with shaft of coiler drum. Control organ is connected with other of said members in such a way that to realize process for supplying lubricant at operation of means for moving segments.

EFFECT: lowered consumption of lubricant, improved ecology of production process, elimination of scratches, constant friction factor between mutually sliding surfaces.
