Abstract

Device for bending the rim (10) of a sheet (9,53), said device comprising a bending roll (7,50), a support block (11,48) for the bending roll, a forming die (6,46) against which the rim of the sheet (9,53) to be bent can be pressed by means of the bending roll (7,50) and a framework (1,42) serving to support the forming die (6,46) on the one hand and means for bringing the support block with the bending roll (7,50) towards the forming die (6,46), said framework (1,42) being executed sustantially U-shaped, the opposite end portions of the legs (4,5; 44,45) of it serving to support the forming die (6,46) and the support block for moving the bending roll (7,50) towards the forming die respectively, said support block (11,48) being provided pivotally or slidably in respect of the web (3,43) of the U-shaped framework (1,42), said support block (11,48) extending over the whole length of the rim of the sheet (9,53) to be bent. Said framework (1,42) can be composed from substantially U-shaped lamellae (2) being provided with holes (25,26,27) in which rods (28,29,34,35) are mounted for holding said lamellae together.
