Abstract

1495961 Sheet forming PLASTONA (JOHN WADDINGTON) Ltd 30 Sept 1975 [4 Oct 1974] 43080/74 Heading B5A [Also in Divisions B8 and F4] Articles 2 are formed from a web 16 of plastics material in a machine 1, after the sheet has been heated in an oven 3, the web being progressively extended by the action of laterally-spaced conveyer chains 5. The latter each comprise spike members 14A which have flanges 17 running on rails 18. A cam surface 18A engages follower portions on alternate chain links, and so causes tucks to form in the chain, thereby bringing the spike members closer together. After this happens, the web 16 coming off a roll 4, engages the spikes over the point of entry to the oven. As the chains pass through the oven 3, a cam surface 18B causes the chain tucks to progressively diminish to zero, thus balancing out in the web, the effect of expansion due to the raised temperature.
