Abstract

1,257,797. Moulding cellular articles. TENNECO CHEMICALS Inc. 5 Jan., 1969 [5 Jan., 1968], No. 39850/68. Heading B5A. [Also in Division B8] The subject-matter of this Specification is contained in Specification 1,246,940, but the claims are directed to an arrangement and method of changing the transverse contour of a longitudinally moving web without changing the relative longitudinal positions of points which lie in the same transverse plane. The web forms the surface on to which the resin is poured for expansion as it is carried through a mould formed by mould segments on endless conveyers and the change of contour is effected with minimum wrinkle formation. [GB1257797A]
