Abstract (en)

1. Apparatus for forming the beads (23, 23', 51, 51') and water-retaining folds (24, 24', 52, 52') by automatically curling and bending of the protruding, trimmed, free longitudinal edge protions (2, 2', 3, 3', 28, 28', 29, 29') on deepdrawn blanks (1, 27) for one-part gutter angles having side walls which are shaped like arcs of a circle adjacent to the corner joint between the abutting gutter angle members, characterized by a) a lower die having aa) a stationary lower die member (5, 31), which conforms to the exterior profile of the blank (1, 27) ; ab) a raising die member (13, 38), which is adapted to be raised and lowered and disposed on that side on which the water-retaining folds (24, 24', 52, 52') are to be formed. b) an upper die having ba) an upper die member (8, 33), which is adapted to be raised and lowered and conforms to the interior profile of the blank and is adapted to be clamped against the lower die member ; bb) a backing bar (10, 35) , which is adapted to be raised and lowered and disposed in a recess (1, 36) of the upper die member on the side on which the water-retaining fold is to be formed ; c) respective curling rods (20, 20', 48, 48'), which are longitudinally and transversely displaceable and are rotatable and adapted to be slidably fitted on the edges of those free longitudinal edge portions (2, 2', 29, 29' which are intended to form beads (23, 23', 51, 51') ; and d) respective bending rods (21, 21', 47, 47'), which are longitudinally displaceable and rotatable and adapted to be slidably fitted onto the edges of those free longitudinal edge portions (3, 3', 28, 28') which are intended to form the water-retaining folds (3, 3', 28, 28').
