Abstract
602,545. Casting composite articles. PLASCO., Ltd. Oct. 16, 1945, No. 27110. Convention date, Jan. 17. [Class 83 (i)] Casting-machines; moulds.- In casting sliding-clasp fastener elements 12 on a tape 14, a predetermined number of groups of elements are cast and then in casting a final group, to produce a predetermined stringer length, an end stop is cast also. This may be done by. using a die having cavities 11 for the elements 12 and a cavity 15 for the stop 16, a sliding rod 22 being provided to block off the passage 21 leading to the cavity 15 except during the casting of the final group. In a modification the nozzle 32, Fig. 2, has two passages 38, 39 to align with passages 31, 30 of a die 29 leading respectively to a cavity 37 for casting a stop and cavities 111 for casting the elements 12. When elements 12 only are required the nozzle 32 is moved relative to the die 29 to the position shown. In another modification a nozzle having three passages is used with the die 29, two of the passages aligning with the passages 30, 31 in one position of the nozzle and one with the passage 30 only in another position.
