STRIP HELICAL ACCUMULATOR Russian patent published in 2013 - IPC B21B41/12 

FIELD: process engineering.

SUBSTANCE: helical accumulator comprises horizontal table for outer and inner rings of accumulated metal whereat idle horizontal and vertical rollers are installed, table rotary actuator, master and discharge rollers, inner stationary guide with vertical idle rollers, discharge inclined guide with cylindrical rollers arranged shifted in height relative to each other to form skew helical surface, and take-up roller. Deformation of strip edges is ruled pout by making said guide as elliptic cylinder with round base with rollers arranged on its surface. Every roller apart from the first one is arranged above previous roller by magnitude Δh set by mathematical relation and shifted relative to its center through angle α_n, also set by mathematical relation.

EFFECT: higher reliability in coiling thin strip used in pipe production, particularly, in continuous rolled strip units.
