APPARATUS FOR MAKING CORRUGATED STRIPS Russian patent published in 1997 - IPC

FIELD: plastic metal working. SUBSTANCE: apparatus for making corrugated strip includes mechanism for preliminary corrugation with sets of shaping rollers and knocking out rollers, braking mechanism with assembling and upper pressure rollers, mechanism for drawing corrugations together having body, lower feeding roller and upper and lower guides. Mechanism for preliminary corrugation includes slide spring-loaded from upwards. Flanges of knocking out members are mounted on axles in slides. Said axles have fixing grooves. Mechanism for drawing corrugations together includes jaws with grooves supporting upper guide mounted on axles with possibility of vertical motion. In walls of said mechanism rams with additional jaws are mounted with possibility of horizontal motion. EFFECT: enlarged manufacturing possibilities due to corrugating strips having different width and thickness, enhanced quality of corrugated strips sue to increased accuracy of their corrugations. 2 cl, 3 dwg
