1323140 Moulding ceramic articles NETZSCH MASCHINENFABRIK Gebr 9 Nov 1970 [8 Nov 1969] 53148/70 Heading B5A Apparatus for moulding and drying ceramic articles includes two shaping machines 12, 121, endless conveyers, 14, 141 and 16 161 extending from one machine to the other in two parallel lines, a drier 18 in which a number of elongated trays 44 each carrying a number of moulds circulate such that each tray in turn is brought to a position between the lines of conveyers, and means for shifting a row of empty moulds from each tray to the conveyers 14, 141 and a row of full moulds from the conveyers 16, 161 to the tray. The endless conveyers in the same line move in opposite directions. At a charging station 8, discs 22, 221 of ceramic are cut from extruded rod and placed manually on conveyers 10, 101 supplying them to turntables 24, 241 rotatable in 90 degree steps and carrying plates 26, 261 against which a ceramic disc is pressed by the upward movement of the end 28, 281 of the conveyers 10, 101 by a drive 30, 301. The turntables 24, 241 overlap turntables 34, 341 having five equidistant moulds 36, and each squeezed disc is dropped on to a mould and shaped. Gripper arms 38, 381 reciprocate to transfer shaped articles on the moulds from the turntables 34, 341 to the conveyer 16, 161, and empty moulds 36 on the conveyer 14, 141 to the turntables. The means for transferring the moulds to and from the trays comprises a reciprocatory carriage 54, Fig. 3, supporting a vertically reciprocable pusher 56 with rows of rollers 58, 60 which engage the empty moulds on the trays and the filled moulds on the conveyer 16, 161 respectively. If one shaping machine fails the two conveyers in each line may be driven in the same direction to provide two endless conveyers driven in opposite directions; the shifting means may be arranged to shift either the whole length of moulds on a tray in one direction to an appropriate line of conveyers or the shifting means is divided into sections co-operating with different lengths of a tray and driven in opposite directions to feed moulds simultaneously on to conveyers in different lines.
