FIELD: process engineering.

SUBSTANCE: invention relates to metal forming and can be used for transverse cutting of shaped steel. Proposed device comprises bed supporting lower stationary knife that serves to support shaped sheet so that shaped ledges get aligned and upper movable knife secured at top part of the device. Top knife consists of two parts with their cutting lines equally inclined at α =(1.5-3)° to horizontal line of lower stationary knife to make cutting start moment coincide with moment of contact between RH and LH of upper and lower knives and make cutting termination moment coincide with passing of scissors upper knife central part through lower knife central part.
