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.
