ROPE TWISTING MACHINE Russian patent published in 2007 - IPC D07B3/06 

FIELD: equipment for manufacture of steel ropes.

SUBSTANCE: rope twisting machine has rotor, charging bobbins containing yarns and positioned within bearing supports, three-roller sections, with number of rollers corresponding to number of yarns, said three-roller sections being positioned on output rotor disk, pressure dies for twisting of cables, and pulling block. Rope twisting machine is further provided with adjusting tightening device made in the form of pulley with handle rigidly fixed with its one end on pulley end, said handle being joined with its other end to output rotor disk by means of spring and screw connection. Pulley is connected with L-shaped double-armed spring-loaded lever through flexible member. Ends of flexible member are rigidly connected through pressure planks with friction surface of pulley at its both sides. Double-armed L-shaped spring-loaded lever reciprocates in radial plane relative to immovable guides rigidly fixed at output rotor disk. Middle roller of three-roller section is located at one end of lever so that it rests upon yarn, and roller surrounded with flexible member is located at other end of said lever.

EFFECT: increased efficiency and improved quality of ropes.
