Abstract
1476177 Continuous foam casting F H ROMANILLOS 20 May 1974 [22 Aug 1973 3 Oct 1973] 22447/74 Heading B5A Apparatus for preventing "doming" during the continuous manufacture of foamed plastics blocks comprises a regulating means in the form of an element which is rigid transversely with respect to the longitudinal direction of movement of the foam and which is mounted for pivotal movement about two spaced parallel axes in response to pressure exerted thereon by the foam, a separating material being provided between the foam and the regulating means. The element may take the form of an angle plate 7, as in Fig. 1. In the arrangement shown, the plate 7 is pivoted at one end to a connected device 9 which in turn is pivoted to a fixed bar 10. Alternatively, as in Fig. 3, a plurality of flat plates 8 may be used, these being pivotally attached to fixing elements 18 which are themselves pivoted at 19. In both Figures a separating material 11 is interposed between the foam and plate. To ensure that the material moves synchronously with the foam, it is attached at 14 to the sheets lining the side walls of the mould by suitable adhesive or adhesive tape. To ensure that gases given off during expansion are not trapped beneath the material 11, a perforating device 21 is provided.
