  • Patent number: 4423823
    Abstract: In a metal container having at least one seam by which two overlapping metal edges are joined together, at least one of the edges (58) has a resilient polymeric layer (56) bonded firmly to the metal, so that when that edge (58) is seamed to a second edge (60) the polymeric layer deforms without destroying the bond, and becomes bonded to the second edge, so creating a seal against leakage. A layer of latex no greater than 0.10 mm thick may optionally be included. Seams to which the invention is applicable include swaged seams, interlocked double seams or longitudinal side seams. In the latter case the polymeric layer may provide the bond to secure a single lap seam.

  • Patent number: 4387747
    Abstract: A high-speed rotary filling machine, for filling containers with carbonated beverages or other flowable substances, has a turret (38) mounted on a horizontal axis (31). The containers (30) are carried in radially-extending positions around the circumference of the turret, open ends facing inwards, and are filled by conventional filling valves (43) within the turret. The centrifugal effect of rotating the turret at high speed is utilized to enable filling to take place over an arc of rotation approaching Spillage problems due to centrifugal effects are avoided by transferring the containers to a linear exit conveyor (58) tangentially at the lowest position (19) of turret rotation, without changing the linear velocity of the container.

  • Patent number: 4246770
    Abstract: In a rotary turret-type machine, in which operations are performed on successive can body cylinders (8) or the like by a mandrel (159) inside the workpiece co-operating with a beading rail (176), each workpiece is guided smoothly into a cradle (151) which so supports and locates it throughout its stay in the machine that axial movement of the mandrel is unnecessary. Each cradle is reciprocated towards and away from the mandrel by a fixed cam (145). Each cradle has a spring loaded support roller permitting eccentric support of the can body during beading. Each mandrel preferably has a quick-acting coupling (200) permitting temporary radial displacement of the mandrel without loss of parallelism to accommodate a can body side seam. This coupling consists of a spring mounted support plate (305) engaging a register plate (304) through three balls (306) mounted in seats (307) in the rings to give radially-yielding tripod support.

  • Patent number: 4049261
    Abstract: A sheet feeder for feeding sheets accurately in correct orientation, especially to a press for blanking pieces from the sheet, has an intermittent sheet-advancing action in which not only the movement of the sheet, but also its orientation with respect to the path of travel and its transverse position, are determined solely by pusher dogs without any need for side guides. The pusher dogs fit in recesses in the rear edge of the sheet in such a way that the transverse position of the sheet is determined accurately by an abrupt discontinuity of the recess or recesses engaging a pusher dog.
