MACHINE FOR COILING STRIP Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: machine has casing 1 accommodating mechanism for forming a roll fashioned as lower bending rollers 2, 3, upper bending roller 4, support rollers 5, 6, pivot axle 10, and two-arm levers 8, 9 provided with idle pressure rollers 14 and 19 intended to embrace the roll 20. Pivot axle 10 is connected to drive in the form of hydraulic cylinder 22. One arm of lever 8 and 9 has through grooves 21 through which roller 13 is passed. This roller is rigidly secured in additional levers affixed to shaft 7. The machine has vertical row of idle rollers mounted on shafts in mechanism for side fencing the roll, and removing roller table 28. The machine can also be provided with additional pressure member in the form of power cylinder. Shafts of idle rollers are located in the plane of movement of the shaft of roll 20 as strip 29 is being coiled. During uncoiling of the roll the center of gravity of the roll is reliably secured between the shafts of the support rollers. EFFECT: enhanced efficiency of coiling. 4 cl, 4 dwg
