Title: Method of and Apparatus for Producing Insulating Tubes
Inventor: NEUMANN PETER
IPC: B29D23/00
Filed: 1967-11-17
Abstract: 1,174,639. Moulding tube insulation. P. NEUMANN. 17 Nov., 1967 [21 Nov., 1966], No. 52411/67. Heading B5A. [Also in Division F2] A continuously moulded foam insulation tube is provided with a moulded slit through and along the wall thereof and with the interior and exterior tube surfaces and the surfaces of the slit covered with protective foil against which the tube is moulded. Tubular insulation comprising a wall 42 of expanded polyurethane, phenolic, P.V.C. or latex foam contained within outer and inner protective foils 40, 41, e.g. of rigid P.V.C., paper, fabric or aluminium, and the latter whereof covers the surfaces of a slit extending longitudinally through the wall 42, is moulded between the foils 40, 41 as these are drawn into a moving moulding channel 3 and forced by expanding foam into respective contact with a stationary core 22 and a core supporting and slit forming plate 23, and with surfaces 6c, 7c of co-operating mould elements 6b, 7b defining the channel 3 and comprising two moving endless chains. The plate 23 extends through one side of the elements 6b, 7b which are driven, and supported against the expansion pressure of the foam by a plurality of chain driven rolls 13, and slide on a bottom plate 16. The outer and inner foils 40, 41 are are continuously drawn off from respective rolls 25, 26 to the inlet 4 of the moulding channel 3, defining a trough into which the foam is dispensed from an assembly 27, 29, 28. The foil 41 has a coating of heat sensitive material, e.g. waxes, thermoplastic resin or silicone, applied to the surface thereof which slides in contact with the stationary core 22 to minimize friction and which may be softened by heat supplied to the mould channel 3 by the exothermic reaction of a suitable foam; alternatively the coating may comprise a dry lubricant based on graphite or molybdenum. Projecting ends 41b of the inner foil 41 are trimmed from the moulded tube by a chain cutter 30 and a circular sawblade 33 may project through the moulded tube slit to cut into the opposite foamed wall of the tube to an adjustable depth, which may extend to the interior of the outer foil 40 to facilitate assembly of the moulding around a tube to be insulated. An applicator 34 applies one edge of an adhesive strip to the foil 40 on one side of the moulded tube slit and a removable strip to the other adhesive edge thereof which is subsequently to be applied to the tube on the other side of the slit. The continuous tube is cut into lengths by a travelling circular saw 38. As an alternative to the slit cutter sawblade 33, the core 22 may be provided with an extension diametrically opposed to plate 23 whereby the slits are entirely moulded. The moulds may be heated.

Abstract: 1,215,769. Loading and unloading. AMF Inc. 12 Nov., 1968 [27 Nov., 1967], No. 53499/68. Heading B8E. In a device for unloading cigarettes from trays into the hopper of a cigarette packing machine, full trays are fed intermittently by a conveying device 4 to a transferring and inverting device 10 whence they are pivoted to an emptying position over the hopper. Whilst they are in this position each tray is engaged by a pivotally mounted clamping unit 26, the inverting device being pivoted back to receive the next full tray, and after being emptied is pivoted to a discharge device 33. In this way each empty tray is removed simultaneously with the feeding of a full tray to the hopper thereby enabling a high production rate to be obtained. The feeding device comprises a conveyer 5 which in conjunction with pivotable stop levers 11 and feed levers 14 feeds the trays one at a time to the supporting stirrup 9 of inverting device 10 where the open upper end of the tray is closed by a sliding cover 110. The stirrup is slidably and pivotably mounted about a shaft 20 and, after receiving a tray, is pivoted upwardly and moved along the shaft to an inverted position above hopper 1 in which position it is clamped by the clamping unit 26 which is retractably mounted upon a support 27 itself eccentrically mounted on shaft 29. The cover 110 is then opened to release the cigarettes into the hopper and the device 10 moved back to pick up the next full tray whence it transfers it back to the hopper. In the meantime, the clamping unit is pivoted about shaft 29 to deposit the empty tray upon the supporting bars 34 of discharge device 33 and is pivoted back to the hopper to engage the next tray. The empty trays are indexed along the discharge device by a pusher 36 actuated by the shaft 29 through a cam 37 and linkage 39.

In the embodiment shown with the vessel in an expanded condition the container is able to hold liquids whilst when the vessel is collapsed, and consequentially the platform 26 in a lowered position piecegoods may be stored and transported on the platform 26. In an alternative arrangement the sleeve is arranged within the container so that it may be collapsed longitudinally of the container. In the collapsed state of the vessel, the platform 26 is spaced from the base-plate 22 by pillars 30. Uniformly spaced tie belts (80, Fig. 6) are secured to reinforced outwardly directed portions of the pleats. The vessel may be maintained in its expanded condition by engagement between twist locks and slots provided in the platform 26 and in a flange portion 42 secured to the outer walls 16, (Fig. 8); alternatively (Figs. 9-11) bolts passing through holes in the outer walls 16 may threadedly engage the platform 26. Furthermore by the suitable positioning of holes in the outer walls 16 the vessel may be supported in a partially expanded condition. This latter result may also be achieved by providing bracing members twist locks (Fig. 7) for engagement in slots in the platform 26 and the flange portion 42. Bracing members, each comprising three parts 50, 52, 54 and a jack, may also-be used to retain the platform 26 in its lowermost position. The container includes a liquid inlet pipe and an air escape pipe 70. A door (78 Fig. 1) or tailgate is provided in an outer wall of the container. The fluid tight seals are effected by clamping the sleeve to the base-plate 22 and the platform by inflatable members 124, 151. The container may have a substantially rectangular (as shown) or circular horizontal cross-section.
