Title: Apparatus for the manufacture of caps for closing bottles and the like
IPC: B21D51/44
Filed: 1965-11-26
Abstract: 1,122,197. Stamping. L.ALUMINIUM FRANCAIS. 26 Nov., 1965 [27 Nov., 1964], No. 50415/65. Heading B3Q. [Also in Division B8] Apparatus for producing caps with inwardly rolled edges for containers comprises a pair of pushers 110, 200 between which the cap is gripped and a punch 400 which forces the edges of the cap around the pusher 110 as it grips the cap and around: a toroidal forming surface 304. The caps are formed from blanks 1 and placed between spaced pushers 110, 200. The pusher 200 and the punch 400 are then in their lowest positions. The pusher 110 is lowered so that a portion 12 of the cap is held against the pusher 200 and the punch 400 is moved upwards, compressing a spring 401, and causing the pusher 200 to rise, forcing the pusher 110 up with it. The pusher 110 slides within a sleeve 120 until a stop 111 engages a stop 121. The spring 401 is stronger than a spring 122 between the sleeve 120 and a fixed shoulder 311 on a.housing 300. Accordingly the pair of pushers 110, 200 and the sleeve 120 rise together until a stop 123 on the sleeve engages the fixed shoulder 311. The upward movement of the pushers 110, 200 and the sleeve 120 is then arrested. The spring 401 is compressed as the punch 400 continues to move upwards, until a stop 402 on the punch contacts the pusher 200, Fig. 5 (not shown). During this time, the punch 400 has turned down a zone 13 of the cap, Fig. 1 (not shown), against the sleeve 120 and also forced the edge of the cap to be rolled inwards against the toroidal surface 304 of a fixed guide member 302, to form a rolled edge (24), Fig. 3 (not shown). The cap is then complete. The proceedings are then reversed, the punch 400 being withdrawn, first by decompression of the spring 401, until the pushers 200, 110 are returned to their initial position, Fig. 6 (not shown). The completed cap can then be removed and a further blank inserted between the pushers 110, 200. The sleeve 120 can be arranged with respect to the pusher 110 to have a recess 125, Fig. 6 (not shown), so that an S-shaped zone 25, Figs. 10-13 (not shown), is formed in the cap. In a diagrammatic illustration of the apparatus, Figs. 1, 2 (not shown), a fixed guide member (300) contains a toroidal surface (304) which forms the inwardly rolled portion of the cap. The pushers (100), (200) and the punch (400) act similarly to the pushers 110, 200 and the punch 400 described above. The guide (300) may be in two parts (301), (300) with the portion (301) secured to the punch 400. The pushers 100, 200 may be of any desired shape, and may carry advertising for imprinting on the cap. The punch 400 may have incisions (404), Fig. 7, 8 (not shown), on its upper edges in order to form serrations on the cap.

D4, to any one of a set of outputs S11 ... S14 of controlled elements, particularly for controlling machine tools or telecommunications switching exchanges, comprises a random-access MOS memory M storing in rows thereof binary orders N O, each row of the memory M also storing a respective binary next address number N L. An order read from the memory M is decoded into decimal form at DL and used to select one of the input detectors by means of a distribution network VD. The data from the selected input detector is binary coded at CE and forms one input of an adder AL whose other input is a next address number from the memory M, enabling the address of the next order to be determined. Distribution networks A1, A2 respectively enable the next address number from the memory M to be replaced by a predetermined next address number or by a next address number selected by a console PE. For output, the orders from the memory M are decoded into decimal form at DS and fed to an order generator GO which enables data stored in working registers E1 ... E5 to be transferred to the outputs S11 ... S14. When one output is fed from a single working register, transfer is effected by an order K fed to a gate P; when either of two working registers feeds a single output the required one is selected by an order K1 or K2 fed to a distribution network A3. A comparator C connected as shown determines whether identical data are present at the input and the output of the working register R1. Details of the gates P are given in Fig. 2 (not shown). Distribution networks VD and A1-A3, which are all similar, are given in detail in Fig. 3 (not shown), and details of the comparator C are given in Fig. 4 (not shown).
