Title: Apparatus for and method of producing continuous foamed plastic bunstock
IPC: B29C39/16
Filed: 1974-07-04
Abstract: 1472916 Continuous casting of foamed bunstock UPJOHN CO 4 July 1974 [23 July 1973] 29703/74 Heading B5A To obviate "doming" of the upper surface of a foamed bunstock during continuous casting of the bunstock in a generally U-shaped mould defined by side and lower conveyers, the lower conveyer is supported so that it inclines downwardly immediately following the position at which the polymer mix is deposited in the mould, and attains a maximum downward inclination between the position at which the foaming commences and the position of attainment of maximum rise; the means supporting the lower conveyer is adjustable to enable the gradient of the lower conveyer to be altered, during operation, between the positions at which the polymer mix is deposited and begins to rise. As shown in Fig. 4, adjustment is made so that the lengthwise configuration of the mould approximates to the mirror image of the rise profile of the polymer mix. In the apparatus described (Figs. 1, 3), side conveyers 34 and lower conveyers 26, 28 are provided with continuous paper lining sheets 38, 36 which define the mould cavity. Polyurethane polymer mix is deposited on to the lower sheet 36 from a reciprocating mixing head 10. At this position the lower sheet 36 is supported on a platform 48 whose inclination may be adjusted by jacks 44, 46. Further adjustment of the configuration of the lower surface of the mould may be made by means of a telescoping platform 51 provided to support the lower conveyer 26 at the area of maximum inclination. In a modification of the arrangement of Figs. 1-4, at least one transversely extending weir is provided in the support means between the positions of polymer mix deposition and commencement of foaming (Figs. 5-8, not shown).

Title: Improvements in and relating to method and apparatus for extruding continuous metal members
IPC: B21C23/21
Filed: 1966-07-01
Abstract: 1,146,909. Extruding. REYNOLDS METALS CO. 1 July, 1966 [7 July, 1965(2)], No. 29739/66; Heading B3P. In the extrusion of a continuous length of product from separate billets 62, a secondary container 40 smaller than the billet is disposed adjacent the die 22 and the extrusion is stopped when the rear end of the billet is flush with the rear end of the secondary container. The secondary container 40 is movable axially by hydraulic pistons 46 and the primary container 50, which may be heated electrically, is movable axially by hydraulic pistons 58; both pistons are pressurised by oil gear pumps. If a long secondary container is used it may also be heated. In operation, both containers are moved to the right Fig. 3 (not shown) to provide a seal against the die 22 and a metal-tight but non- air-tight seal between the two containers. A pre-heated billet 62 of aluminium or aluminium alloy is placed into the primary container bore followed by a dummy block 60 which is fixed to or preferably seats upon a projection 66 of an hydraulically actuated extrusion stem 14. The latter presses the billet against the die face, upsets it within the container bore and then extrudes it through die 22 to form a product (63) which may be hollow or solid and may be of angle or channel shaped cross-section. Any air trapped in the container bore can escape between the two containers. The die 22 is cooled by coolant such as air supplied through pipe 36 to groove 32. When the rear end of the billet is flush with the rear end of the secondary container, Fig. 5 (not shown), extrusion is stopped, the primary container is retracted, the dummy block is removed by a shear 70, the primary container is again moved to the right, a fresh billet and dummy block are inserted and extrusion recommences. Since no air is trapped in the container bore, pressure welding of the billets takes place thereby providing a continuous length of extruded product. When a sufficient length of the product has been extruded the discard is severed by a shear 72 or, after pulling back the extruded product, by the shear 70. The dummy block may be lubricated with high temperature oil and then heated in air before being placed into the container bore. A single axially movable shear may be used instead of the two shears 70, 72. In other embodiments, Figs. 7-9 (not shown), the secondary container is incorporated within the die housing and is stationary. The extrusion press may be horizontal or vertical.
