    • 771,712. Making wafer sandwiches. WOLF, P. July 4, 1955 [July 13, 1954], No. 19259/55. Class 28(1) Filled wafer strips are made by placing a layer of standard-size wafer sheets on a table or conveyer with the sheets abutting one another longitudinally and if desired transversely, spreading a layer of filling over the wafer sheets and then placing a further layer of wafer sheets on top so that the joints between separate wafer sheets in the upper layer do not coincide with the joints between wafer sheets in the lower layer. As shown, wafer sheets are deposited on to conveyer belt 1 and are fed, assisted by a feed roll 2, under a device 3 to receive a layer of filling. A layer of wafer sheets is placed on to the filling and the strip is then compressed by a roll 4. A second layer of filling may be deposited from device 5 on to the strip and a further layer of wafer sheets deposited on the filling, the joints between these wafer sheets being offset from the joints between those of the layer immediately beneath. A further roller 4 1 compresses the strip again. Further layers of filling and wafer sheets may be added as required. The finished strip is cut up.

    • Dough &c. is moulded by means of a roller the moulding part of which consists of one or more polymers and/or copolymers of unsaturated organic compounds, e.g. polymers of acrylic and methacrylic acid esters, especially methacrylic acid methyl ester, acrylic nitrile, vinyl chloride or acetate, vinylidene chloride, styrol, allyl esters of acrylic and methacrylic acid, allyl diglycol carbonate and diallyl esters of phthalic acid, succinic acid, oxalic acid and phenylphosphinic acid, with or without fillers, colouring matter &c. In examples, (2) a hollow metal roller 1 has circumferential ribs 3 which define circumferential hollows. These hollows are filled with a composition 4 comprising polymethyl methacrylate (95 per cent), graphite, talc and carnauba wax. The mould recesses 5 are then filled in; (3) a roller is provided with square depression in its surface. These depressions are filled with a polymer-monomer methyl methacrylate mix containing carbon black, stearic acid and benzoyl peroxide, and a lead matrix the surface of which corresponds to the goods to be produced is pressed into the mix. The roller is then heated to complete the polymerization and the matrix is removed, leaving mould recesses in the hardened polymeric material in the depressions; (4) the monomer-polymer mix comprises a copolymer of vinylidene chloride and acrylonitrile, polymethyl methacrylate and monomeric methyl methacrylate.
