Abstract

Apparatus for forming a bend in sheet material comprises two pivotally mounted jaws (10 and 12) between which is a gap (13) for receiving sheet material (14) which is fed incrementally or indexed through the jaws (10, 12) in the direction of the arrow 15. Rotation of one or other jaw by a controlled amount, together with a controlled extent of incremental feed of the sheet material (14) applies to the sheet material a number of incremental bends which in total form the desired curved profile to be introduced in the sheet material. Other embodiments use linearly movable heads to engage the sheet material as the latter is incrementally fed, instead of pivotally movable jaws.
