Abstract

1339873 Rolling wheels J M PLAGEMANN [trading as PEE-WEE MASCHINENUND APPARATEBAU WERNER PLAGEMANN] 28 Feb 1972 [3 March 1971] 9113/72 Heading B3M A belt sheave or similar article is made by forcing a pair of opposed rollers 10, Fig. 1, against a disc-like blank 12, the rollers progressively forming a groove in the blank, Fig. 3. The shape of the blank is defined by the rollers and a pair of chucks 19 and 20 which support the blank. Lateral recesses may be provided in either the chucks or rollers (Figs. 4, 5, not shown) to accommodate excess material during rolling. The rollers 10, Fig. 6, are driven in the same sense, whereas the blank is freely rotatable. The rollers are supported in slides 105 and 106 which are urged towards and away from the blank by arms 119 and 120. The arms are pivoted at 121 and 122 and are shifted by respective rams 115 and 116 carried on a shaft 109. The shaft is oscillated by a hydraulically operated rack and pinion mechanism (Fig. 7, not shown). The working stroke of the rollers 10 can be adjusted by shims 130, 140 and nuts 141, 142 associated with the two slides. The chucks 19 and 20, Fig. 10, are urged together by a spring 193 and are movable axially on a spindle 192 by means of a pistonrod 205. Movement of the chucks is controlled by stops and micro-switches, the machine being automatically switched off in the event of a malfunction. The operation of the rack and pinion mechanism is also controlled by microswitches in response to the angular displacement of the shaft 109. (For Figures see next column.)
