Abstract
1381524 Moulding cap liners SACMI COOPERATIVA MECCANICI IMOLA 17 Jan 1972 [10 April 1971] 2072/72 Heading B5A [Also in Division B8] Plastics material for shaping into a sealing gasket of a crown cap 2 by compression or centifuging is only deposited from a nozzle 43 if a cap 2 is present on a support 3 when the support and nozzle are brought together. When a cap is present a bush 49 slideably mounted on the nozzle is pushed up against spring 50 and, via arms 52, 53 and rods 56, 14, closes a ball valve 17-22. Plastics material supplied to inlet 5 passes through apertures 16, 18 and 17 to fill ducts 9, 23 and 42a. Piston 24 is forced down against spring 41 into duct 23 and raises the pressure of the material until spring loaded valve 46 opens and material is ejected from the duct 42a and out of the nozzle 43. However, if valve 17-22 has not been closed by the presence of a cap 2 the pressure of the material is insufficient to open valve 46 and the material flows from duct 23 through valve 19 to the part of duct 9 vacated by piston 24. Piston 24 is controlled by a cam (not shown), against which a cam follower 40 runs as the device is moved about a rotating head (not shown). Upward travel of the piston is adjustably limited by extension 35 engaging stop 37. Packs of gaskets 13 and 29 in stuffing boxes around operating rods 14 and 27 are subjected only to the feed pressure and not to the ejection pressure.
