ABSTRACT:
An improved apparatus for forming plates of irregular cross-sectional shape has a plate-form die which cooperates with a plurality of reciprocating rollers for forming a strip of plate material which is passed incrementally between the rollers and the die. The die includes a plate surface portion having a wedge-shaped leading end portion for forming a groove in the plate material. The rollers reciprocate with a stroke which is less than the length of the plate surface portion.
