Abstract

A method of and apparatus for bending a corrugated sheet transversely of the direction of corrugation, the corrugated sheet being of the type having a plurality of parallel ridges and troughs formed by ridge tops (17) connected to ridge bottoms (18) by intermediate side walls (19 and 20). The apparatus comprises a first tool (11) in the form of a pressure bar formed along the length thereof with alternating projections (16A) and notches (16B) and a second tool (10) in the form of an elongate member (12) carrying a plurality of projections (13), a channel (14) being provided in each projection (13) to receive the first tool (11) in use of the apparatus. In use of the apparatus, a cor­ rugated sheet is pressed between the first and second tools so that each projection (13) of the second tool (10) enters a re­ spective valley between two ridge tops (17) of the corrugated sheet and the first tool (11) enters the channels (14) of the pro­ jections (13) to form a fold (22) extending transversely of the corrugations and into the valleys of the corrugated sheet. The trough bottom (18) of each corrugation is brought into contact with the base of the respective notch (16B) during the pressing operation and at the same time the side walls (19 and 20) of the respective valley contact the edges of the notch (16B) whereby the portions (19A and 20A) of the side walls between the point of contact with the notch edge and the trough bottom (18) are moved away from the valley (21) and the portions (19B and 20B) of the side walls between the point of contact and the ridge top are moved into the valley.
