METHOD FOR FORMING OF WEAVER'S BEAM AND APPARATUS FOR EFFECTUATING THE SAME Russian patent published in 2006 - IPC D02H13/28 D02H3/00 

FIELD: textile industry.

SUBSTANCE: method involves winding warp threads on warping shafts; comparing theoretic winding radius with actual one and unwinding bobbins on warping column of smoothing machine at equal angular velocity, with unwinding of shafts on smoothing machine being performed at minimal and constant braking moment created by friction in bearings and friction in rigid kinematic connection of warping shafts; providing compensation of draft change in compaction unit-winding body contact zone by changing movement value of compaction unit in accordance with expression: ▵Ρ_a=▵Ρ_n-(Ρ_a-Ρ_m), where ▵Ρ_a is value of actual movement of compaction unit; ▵Ρ_n is nominal value of movement of compaction unit; Ρ_a is actual winding radius; Ρ_m is theoretical winding radius. Apparatus has electric engine, reducer, friction coupling with switching on-off unit, and cam pair, whose first member is kinematically connected to compaction unit and second member is connected through reducer to electric engine.

EFFECT: increased efficiency by providing minimal draft during unwinding of warping shafts.
