PRELOADED CRATE Russian patent published in 2019 - IPC B21B31/30 

FIELD: metallurgy.

SUBSTANCE: pre-loaded stand for producing oriented material from amorphous-crystalline polymer in powder form includes first crossbar, first working roll, second working roll, working roll cushions with work roll bearings installed in them, second crossarm, power bolts tightening both cross beams. Improved accuracy of monolithic workpiece, simplification of adjustment and adjustment of stand due to that it comprises first and second spacers, placed between pillows, the first rusk and the second rusk for transfer of pressure from the second traverse to cushions, into one of the said blocks or both are additionally mounted a strain gage for measurement of contraction force. Pads may include adjusting eccentric bushings in which seats for roll bearings are made. Cylindrical rolls have ellipse shape in cross-section, ellipse parameters of both rollers are identical, shafts of rolls are connected by gear transmission ensuring equality of their angular velocities. Eccentricity of ellipses can vary from 0.01 to 5 % of size of smaller radius.

EFFECT: invention relates to processing of composite materials.
