Title: Apparatus for molding articles from a paste-like material
IPC: B29C43/00
Filed: 1969-01-28
Abstract: Articles are made from paste like material e.g. wood pulp and binder by delivering a charge of material into a moulding tunnel closed at one end by a movable insert and advancing a two part piston in two stages along the tunnel to press the material against the insert. Moulding material is fed from hopper 8 into the tunnel 7. Insert A 1 closes one end of the tunnel and the other is closed by a two part piston comprising pistons 10 and 11. Two horizontally opposed pistons 17, 18 and a vertically acting piston also operate to compress the moulding material. The operation of the apparatus in moulding the end for a box having a flat portion and a surrounding rib is shown in Fig. 9 from which the tunnel has been omitted. Piston 10 first moves in the direction of arrow 20 to form the flat portion of the box end against insert A 1 which is held in position by stops 15. Side and base plungers 16, 17 and 18 are moved in to define the rib portions and these portions are compressed to their final density by part 11 of the composite plunger. Plunger 10 has an outstanding rib which forms a groove in the moulding to co-operate with a rib 12 on the adjacent insert A 2 in the curing tunnel. The plungers 16, 17, 18 are withdrawn, stops 15 are raised and the plunger 10 forces the insert A 1 and moulding 1, together against the previous moulding and into the curing or drying tunnel 24. At the end 30 of the drying tunnel 24, the end moulding and insert A 6 are separated from the others by a plunger 27 with a wedge shape head which engages projections 25 on the inserts A. The moulding is separated from the insert and removed by conveyer 32 and the insert is pushed by plunger 33 on to conveyer 35. The insert is moved along conveyer 35 in the direction of arrow 36, until it is fed back to the moulding tunnel 7 by plunger 40 the drive of belt 35 incorporating a slipping mechanism so that it advances an insert to position A 9 only when the previous insert and the plunger 40 are clear of the conveyer. In another embodiment (not shown) the whole of a box is moulded in one operation, the hopper being moved laterally to the right and a feed plunger supplied so that a pressing plunger acting vertically downwards on the moulding may also be used. The insert is made in two relatively slidable parts to assist ejection of the moulded article.

Title: Snap attaching apparatus
IPC: A41H37/10
Filed: 1972-12-07
Abstract: An improved feed arrangement is disclosed for feeding two component fasteners, such as buttons, snaps and the like having a pronged element and a backing element, to an apparatus which attaches the fasteners to material, such as a garment. The feed arrangement for each component includes a hopper-chute assembly, a guide channel and a driving means. Each hopper-chute assembly is readily detachable from the apparatus to provide rapid substitution of one type or style of fastener for another and includes means preventing discharge of elements from the chute when the assembly is detached from the apparatus. The guide channel and drive means are arranged to receive elements from the chute and move them successively in a single step to a setting station where an anvil and a ram forcefully bring the elements together. The guide channel for the pronged elements is formed by a pair of spaced, opposed wall members spring biased towards each other. The wall members have faces of non-linear shape and taper towards each other in the direction of feed to form a labyrinth configuration therebetween. This configuration serves to align the prongs with the axis of the channel so that they will not be prematurely and unwantedly deformed by jaws on the anvil.
