Abstract: 804,751. Printing processes; stencilling apparatus. MURRAY CURVEX PRINTING, Ltd. March 22, 1955 [March 22, 1954], No. 8245/54. Class 100(2) A process for printing or decorating in two or more colours, comprises first depositing two or more colours of the required pattern on a flat intermediate surface to form the complete two or more coloured pattern, the resulting design being then offset from the intermediate surface by a resilient pad by means of which the pattern is printed on to the curved surface of an article. As shown, a table 15 has troughs 16, 17, 18, 19 carrying silk screen stencils 16a, 17a, 18a, 19a. The table 15 is rotatable about a base 20 and has stops 22, co-operating with a fixed stop 23, to register each stencil directly above a plate 11, preferably of stainless steel, whereby parts of a design carried by each stencil may be transferred to the plate 11. The stencils may be individually adjusted with respect to the axis of rotation of the table by adjusting screws 27 in threaded lugs 28 provided on the table. Colouring agents, which may be thermoplastic, are pressed, by individual squeegees 26, after heating by infra-red lamps 29 or by electric current if the screen is wire mesh, on to the plate 11. When four colours, one for each stencil, have been deposited on the plate 11, the plate 11 is moved on a carriage 12 along a bed 10 beneath a resilient pad 13, Fig. 3, reciprocable towards and away from the plate 11. The pad 13 removes the composite design from the plate 11 and subsequently desposits same on an article, e.g. curved ceramic ware, carried by a carriage 14. The plate 11 and pad 13 may be coated, before receiving part or the whole of the design respectively, with a film of material which remains tacky under normal atmospheric canditions. In a modification, Fig. 5 (not shown), the table, instead of being circular is rectangular and is movable transversely of the bed to register each stencil above the plate 11. In each case, the table may be moved manually, or automatically or semiautomatically by mechanical, electrical or fluid operated mechanism. The design may be deposited on the plate 11 by spraying the colours through stencils. Specification 735,637 and 736,312 are referred to.

A guide-fork 49 is provided for the cable 24. The pulley 11 is carried by a cable 10, Fig. 7, passing round pulleys 9 mounted on fixed spindles 55. The cable 10 has its ends attached to springs 13, the ends 15 of which are attached to cables 14 partly wound around spring- controlled rollers 16 attached to guides 21 and normally holding them in the lower position. The tension on the cables 14 during cutting rotates the rollers 16 and raises the guides 21 to the position shown in dotted lines, Fig. 3, the cutting-wire being then drawn down through the gap 44 into the slot 7 between the two tables 6. Cams 34 on the guides are held in the raised position, during the cutting operation, by levers 35. Fig. 2, which carry a bridge 40 at their free ends. When the cutting operation is finished, the cutting-wire strikes the bridge 40 and sets free the cams 34, thus allowing the guides to return to their normal positions. When the cutting-wire 30 is not in operation, a separate cutting-wire attached by means of a hole and slot to a rotatable cross-bar may be fitted in opposite recesses 60, the tables 6 being slid back to uncover the recesses and then moved forward to hold the bar in position. A cutting-wire with two handles mav be used for cutting extra large cheeses, one end of the wire being passed beneath the guides 21 at 44 to the end adjacent the hinged door 50, which is dowel-pinned at 52.
