697,071. Moulds for casting confectionery &c. SOLLICH, R. Jan. 8,1952, No. 552/52. Class 87 (ii). In a mould made of flexible material such as rubber (the mould being flexible to permit deformation thereof to effect ejection of the fondant centre &c.), the outer edge or rim of the mould, and the bottom of the mould, are substantially shape-retaining and non-deformable, whereby damage to the fondant centres during ejection is reduced. 'Fig. 1 shows a mould made of rubber and having a rim 2 stiffened by a metal reinforcement 5 which may be sheet metal, wire - or a shaped section. The base is reinforced by a rigid metal plate 4a vulcanized thereto. The intermediate part 3 is flexible. Fig. 2 shows a mould 1b in which the reinforcement 5 is embedded in two sides of the rim. In Fig. 5 the top 9 and bottom 10 of the mould are of relatively non-deformable material such as thermoplastic resin, and the middle portion 11 is of flexible rubber. In Fig. 6 the necessary rigidity of the rim and base is obtained by making these parts of thick rubber, 7 being a frame into which many moulds are slid to form a beam which forms part of a conveyer chain for casting purposes; the mould has a rib 12 which fits into a groove in the frame. Fig. 3 shows a beam construction comprising a continuous metal frame 6 having holes therein in which the moulds are positioned, the longitudinal edges being reinforced at 5 as shown in Fig. 2. Fig. 7 shows a casting machine in which the moulds, formed into beams 14 linked together to form an endless conveyer are fed past a casting hopper 15, air coolers 17 and 18, ejection device 19 and a cleaning and dusting device 22 actuated in timed relation to the movement of the moulds. The device 19 deforms the moulds and the articles fall out of the moulds on to a discharge conveyer 20.
