Abstract

822,746. Moulding telephone finger plates. GENERAL ELECTRIC CO. Ltd. Oct. 4, 1957 [Oct. 4, 1956], No. 30307/56. Class 87(2). [Also in Groups XXXV and XXXIX] A telephone finger-plate is made of rigid P.V.C. by a pressing operation. A blank 29 is placed on an annular jig 30 and heated until it is pliable. A die 13 is lowered and the several holes punched, the die depressing member 31 against spring pressure to remove the heating jig 30. The supply of air through a part 32 holds the plate firmly against the fixed die until the plate is cool. The upper die 13 is then lifted and the plate 29 is ejected by air supplied to part 37 driving rubber disc 38 and pins 40.
