Abstract
1,081,694. Feeding foamed material to moulds. GOODYEAR TIRE & RUBBER CO. Aug. 4, 1964 [July 17, 1963], No. 30525/64. Heading B5A. [Also in Division G3] A method of making foamed elastomeric synthetic resin articles, e.g. cushions and crash pads, comprises dispensing foamable mixture at a substantially constant rate into a mould and moving the mould at a variable relative speed with respect to the dispenser so that deeper parts of the mould receive a greater quantity of the foamable mixture than do shallower parts. In the embodiment shown, various moulds 11, 12, 13 are moved on rails 15 by an endless chain 16, each mould being provided with a system of bars 21 on which cams 22 may be preset to operate trip switches 23 on a switching unit 24 in a predetermined manner. Switching unit 24 is electrically connected to a variable speed motor 18 so that each mould moves at speeds beneath dispensing unit 25 commensurate with the internal configuration of the mould. In addition dispensing unit 25 may also be movable longitudinally or transversely of the mould, its movement being predetermined by settings of cams 22. Likewise may be controlled starting and stopping of the flow of fomable mixture and flushing of the nozzle.
