Abstract

1,066,045. Moulding corrugated sheets. BELL MASCHINENFABRIK A.G. Aug. 11; 1965 [Aug. 21, 1964], No. 34418/65. Heading B5A. In a process for producing corrugated sheets, e.g. of asbestos cement, the sheet in a deformable state is placed on a flexible membrane resting on parallel supports the spacing between which is then reduced to cause sagging of the membrane and sheet between the supports. The supports are tubular and are each connected to a source of vacuum and have perforations which co-operate with perforations on the membrane. The movement of the supports between maximum and minimum spacing is effected by hydraulic, pneumatic. electrical or mechanical means.
