METHOD OF COLD SHAPING OF FINISHING ACCESSORIES, AND AUTOMATIC TRAIN FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC B21D5/06 

FIELD: metallurgy.

SUBSTANCE: prior to feed to a roll forming mill the tape is fed through an orienting device. Then gradual, performed with a uniform step bending of end longitudinal edges is performed. Further a shape angle is formed with a definite step. Wherein the position of the shaping rollers is changed. In an automatic train a receiving unit is used in the form of the orienting device made in the form of guides with slots installed on carriages with a possibility of movement in the direction transverse to the rolling axis, the cutting assembly contains a removable matrix and a knife. Wherein work cages are made in the form of pulling, rolling and shaping cages. The rolling cages are installed in turn with the pulling cages, have screw guides, and are made with a possibility of the rollers position regulation. The rollers at next to the last and last rolling cages are located in a staggered order, and in the shaping cages pair rollers with equal seating dimensions and equal diameter are used.

EFFECT: increased capacity and quality, simple design, expanded functional possibilities of the method.
