Abstract

1535781 Corrugating COVRAD Ltd 8 April 1976 [21 Jan 1975] 2529/75 Heading B3E Sheet having corrugations of generally triangular form, so as to include two sets of aligned longitudinal portions interconnected by transverse portions, wherein the aligned longitudinal portions are closely adjacent and outwardly curved, has the curved portions flattened by passage past force transmitting means applied to the portions and having a component of movement in the direction of passage of the material, and a component transverse thereto. In the figure, corrugations initially formed as at 10, are closed up, portions 12 becoming outwardly curved. The material is then advanced between opposed surfaces 18 on arms 19 sliding in bores 22 in freely rotary members 23 and oscillated by crank pins 20 on shafts 25, whereby when the surfaces 18 contact portions 12 to flatten them, they move with the portions in the direction of material advance.
