ABSTRACT:
Apparatus for shaping sheet material such as metal foil includes co-operating rollers with teeth, between which the sheet material is fed. The teeth shape the sheet to form corrugations, and projections on the flanks of the teeth form patterns on the corrugations. In order to free the shaped sheet from the teeth, resilient material projects from the flanks of the teeth and urges the sheet away from the flanks after a shaping operation.
The invention is intended for use in forming the secondary heat exchange surfaces in aluminium radiators.
