TRAILER FOR MOVEMENT AND UNWINDING OF THREAD-LIKE MATERIAL FROM BOBBIN

摘要

FIELD: mechanical engineering; unwinding of polyethylene pipes, cables, hoses, wire ropes. SUBSTANCE: proposed trailer has frame mounted on running gear and carrying coaxial grips and brake fitted in bearings. Each grip flange with through holes through which removable rods are passed installed for controlled radial displacement relative to flanges. Guide arrangement secured on frame is essentially a row of at least three rollers with axles parallel to grip axle fitted in housing. Middle roller is installed for controlled displacement over plane passing through extreme roller axes. Housing is secured on one end of link hinge secured by other end on frame for turning in space between flanges. EFFECT: provision of controlled feeding of thread-like material from coil fixed by inner diameter. 4 cl, 3 dwg
