Abstract (en)

[origin: EP0205992A2] Plane, rectangular sheets (10) are bent around a driven bending roll (32) by a number of back-up rolls (34) and pressure rolls (52, 56). The almost completely rounded sheet (10) is bent resiliently away from the bending roll (32) by a deflecting member (62) to prevent its front edge (10a) from re-entering between the bending and back-up rolls before its rear edge has travelled through between them. Then the deflecting member (62) is retracted and the front region (10a) of the sheet (10) springs back towards the bending roll (32) to be gripped again by the rolls. When the front edge (10a) of the sheet (10) has reached the gap between the last two pressure rolls (56), all the pressure rolls are lifted. The sheet (10) is then conveyed axially from the rounding station (31) but continues to be rotated by the bending roll (32) until its front edge (10a) is arrested by catching levers. The rounded sheet (10) is now stripped axially off the bending roll (32). <IMAGE>
