摘要： 1334168 Dip-moulding; stripping BAXTER LABORATORIES Inc 19 April 1971 [26 Feb 1970] 22465/71 Heading B5A A machine for stripping flexible products, e.g. gloves 115, from dip-moulds 111 attached to a continuously moving conveyer comprises an array 109 of pairs of arms 110, means for moving the array parallel to, and at the same speed as, the conveyer, with each arm pair centered over a mould, means for sequentially moving the array towards the moulds, clamping the pairs of arms on to respective moulds whereby the products are gripped thereby, spreading the arms of each pair and then moving the array away from the moulds to strip the products. Each arm of a pair has fingers 113a, 113b for clamping on to a glove cuff, and when the arms of a pair are brought by means 133 into engagement with the product the fingers are brought together to clamp the cuff. The array is connected to a carriage 116 mounted on guide rods 117 and is lifted or lowered by a piston and cylinder 118, 119. The carriage is driven at the same speed as the conveyer by a chain and sprocket assembly 121, 122, 124, 125 in which dogs 127, 128 on drive chain 125 engage a catch on the carriage, and the latter is driven against the piston-rod 129 of a constant pressure air cylinder whereby when the carriage is disengaged it is returned to its original position. The carriage has trips for sequentially actuating microswitches controlling the stripping operation. The arm pairs act on alternate rows of moulds and the arrangement is such that on return of the carriage to its initial position the remaining moulds become aligned with the mould pairs. A horizontally reciprocable platform is brought below the array when the gloves have been removed from the moulds to receive the gloves from the fingers; the platform is then moved to a position above conveyers which receive the gloves when trap-doors on the platform are opened.

摘要： 1324516 Stripping tubes from mandrels ARMSTRONG CORK CO 31 July 1970 [1 Aug 1969] 37168/70 Heading F2P Apparatus for stripping tubes from mandrels comprises means for injecting a fluid at high pressure into the interface between the tube and the mandrel, means for massaging the outer surface of the tube on the mandrel and means for effecting relative lateral displacement of the tube and mandrel. As shown, tubes 10 on mandrels 12 are fed, by conveyer means, intermittently to stripping apparatus 16. Each tube operates a cycle actuating switch 26 on its way to the valley between drive roll 32 and eject roll 34. When the tube is in position, top roll 48 descends so that the tube on the mandrel is massaged between the rolls 32, 34 and 48. High pressure fluid is injected from the pivoted nozzle 58 at the end of the tube to the interface 62 between the tube and the mandrel which with the massaging effect of the rollers loosens the tube from the mandrel. An axially moving ram (72) (Fig. 1, not shown) is then operated to push the mandrel out of the tube whilst the latter is held axially by the rolls. The mandrel is fed away by rolls (100). Roller 34 is then moved to the dotted line position 110 and the ram (72) retracted so that the tube 10 falls into trough 112. The relative positions of the rolls 32, 34, 38 and the ram 72 are adjustable for different sizes of tubes and the nozzle 58 is so pivoted at 64 that it will always contact the underside of mandrel 12.

摘要： 1312019 Moulding by spraying STRUCTURAL FIBERS Inc 24 Aug 1971 39657/71 Heading B5A A fibre reinforced preform, Fig. 1a, comprising a tube 10 closed at one end by an integral wall 12, is formed by directing chopped fibre on to a rotating former 26, Fig. 1, having apertures through which a vacuum is applied to hold the fibres and by spraying the fibres with a thermosetting resin to join the fibres without filling the voids between them. The fibres are generally randomly orientated but with a predominant orientation along a spiral around the tube 10. A filament may be wound round the tube 10 for additional strength. The porous preform is subsequently made into a tank or pressure vessel by completely impregnating it with epoxy resin, placing the preform in a mould which closely conforms to its exterior, and inflating a bag within the preform to compress its walls while the epoxy resin is heat cured. In the embodiment the former 26 may take the form of Figs. 4 and 6 where support 65 has rods 68 mounted on plate 66 and carrying a perforated hemispherical former part 71. A cylindrical part 74 carrying lugs 76 is joined along a longitudinal seam by pins 80 to lie around the support 65. In the form of Fig. 7 the former is in two parts 102, 103 separable along a plane indined to the cylinder axis. Part 103 has lugs 109 and part 102 a mounting plate 101. The machine for moulding the article, Figs. 1, 2, comprises a tube 24 rotatable by motor 29 relative to fixed tubes 31, 37 through which a vacuum is applied. The former 26 is attached by its mounting plate 66 or 101 to the rotatable tube 24 and lies within an openable oven 54. As shown in Fig. 2 there are two tubes 24 and associated apparatus alternatively connected to the vacuum system by flap 38. On the left of Fig. 2 the oven 54 has been closed by sliding the top 61 over the former 26 and pivoting the casing 56 to enclose the former. Glass fibre 82 is cut up and directed on to the rotating former 26 by choppers 44, 46 and the thermosetting resin is sprayed by nozzles 51, 52 carried on arm 53. The choppers and nozzles are mounted on a frame 41 suspended from and driven back and forth along a beam 39. The arm 53 is pivoted to frame 41 so that the nozzles can be moved out of the way to close the oven. After a layer of resin and fibre has been deposited on the former 26 a single filament may be wound round the layer by a filament metering device 111 travelling along the rotating former. The article is then cured by burners in oven 54 after which actuators 78 move stripper ring 77, which engages the projections 76 or 109 on part of the former, to separate that part from the other part and facilitate removal of the article.

摘要： 1278161 Moulding hollow articles ELECTROSTATIC EQUIPMENT CORP 7 April 1970 [7 April 1969] 16518/70 Heading B5A A method of moulding hollow articles on an inflatable bladder in which electrically charged particles are caused to attach to the bladder and fuse into a coherent article from which the bladder is later detached. A chamber 30 contains an inflatable form 116, to which material is supplied from a hopper 20 through a conduit 21. The particulate material passes through the bottom of chamber 30 into an air chamber 42 where it is blown through valves 48 and guns 44 back into chamber 30 and over the form. The form 116 is supported on a tube 54 having an air hose 60 connected to a pressure source. The tube is rotatably supported on a block 52 which moves on track 50, a rack 58 andpinion 56 being provided to rotate the form as the block moves. A voltage source 64 has one pole connected to guns 64 and the other to a contact assembly 62 which in turn is connected to the form 116. In this way, particles passing through the gun become charged and are attracted to the form 116 to provide a layer of material thereon. The coating chamber forms part of a continuous system in which the forms are positioned on a continuous conveyer and move through a pre-heating oven to the coating chamber then through an oven and a cooling chamber to a device where the moulded articles are separated from the moulds. The material may be in the form of a fluidized bed of charged particles through which the form is passed to be coated. Materials which may be used are vinylidenes and vinyls (e.g. polystyrene and polyvinylchloride), olefines (e.g. polyethylene, polypropylene) cellulosics and polyamides such as nylon.

摘要： A machine for producing pulp bats has a rotary shredder, a vacuum drum with small openings in its periphery and duct means to convey shredded pulp from the shredder to the vacuum drum. An inner drum cuts off the openings from the vacuum to release material from the drum. Advantageously air jet means assist in releasing material from the drum. In one embodiment, guide means are adapted to guide a porous sheet to pass over a portion of the drum for the accumulation of shredded pulp on the porous sheet and then from a terminal position away from the drum. Means guide a second sheet adjacent the said terminal position to retain the accumulated shredded pulp between the porous sheet and the said second sheet. In a second embodiment, the shredded pulp accumulates directly on the drum and means guide a pair of opposed sheets adjacent the point of release of the shredded pulp from the drum to entrain the accumulated shredded pulp and carry it away from the drum.
