FIELD: plastic metal working, possibly shaping sections of strip in shape bending mill. ^ SUBSTANCE: apparatus includes rotary shape bending rolls with grooved working surfaces forming roll passes. Each roll is provided with plate of grease material, with mechanism for pressing grease plate to shape bending roll and moving it and also with guides for said grease plate. Said guides are mounted relative to roll at side opposite to rolling plane and they are arranged in plane passing through axes of shape bending rolls. Grease plate is placed in guides with possibility of lengthwise motion by action of mechanism for pressing it to roll and it has working profile respective to roll grooved pass and width consisting 0.1 - 0.3 of minimum diameter of roll grooved pass of respective roll. Graphite may be used as grease. ^ EFFECT: enhanced quality of shapes due to lowered number of rejected shapes, improved strength of tool. ^ 2 cl, 2 dwg, 1 tbl
