PCT No. PCT/SE89/00105 Sec. 371 Date Aug. 15, 1990 Sec. 102(e) Date Aug. 15, 1990 PCT Filed Mar. 7, 1989 PCT Pub. No. WO89/09101 PCT Pub. Date Oct. 5, 1989.The invention relates to an apparatus for bending a flange against a workpiece (3). A preliminary bending tool (5) on a first tool holder (7) is carried by a linkage mechanism (8-13) for movement in relation to a stand (1). A bend finishing tool (6) on a second tool holder (14) is carried by a parallelogram linkage mechanism (15-20) for movement in relation to the stand (1). The first linkage mechanism (8-13) forms a parallelogram having a line between the axes (10,11) of the links extending perpendicularly to a line between the axes (17,18) of the second linkage mechanism (15-20). One single drive member (21) is connected to the parallelogram linkage mechanism (15-20) to drive the second tool holder (14). A drive link (28) is connected between the parallelogram linkage mechanism (15-20) and the first tool holder (7) to drive this. |
