  • Patent number: 4938649
    Abstract: Apparatus and method in which stacks of tin ends are formed and fed longitudinally to a three-endless belt conveyor in spaced relation of stacks with turns in the feed paths after the first conveyor being defined by overlapping separate three-endless belt conveyor assemblies. The stacks of tin ends may be unwrapped or they may be wrapped, in which latter case, an unwrapping station is provided at which the wrapping is both cut and the wrapping peeled away in response to rotation of the stack. The unwrapped stacks in any case are fed into a continuous stream to a closing station where the individual tin ends are applied to can bodies. In one unwrapping embodiment, the stacks are fed to a first conveyor through the intermediary of a pestle and gripper which are fed in unison to travel a stack to the first conveyor and provision is also made to relax the grip of the pestle and gripper while the wrapper is peeled away.

  • Patent number: 4821638
    Abstract: An apparatus for successive printing of cylindrical objects includes a driven carrying wheel; a number of spindles on the wheel freely rotatable about their longitudinal axes parallel to the axis of rotation of the carrying wheel; a printing station radially adjacent the path of the spindles for successively printing the objects; and structure for detecting possible absence of an object and connected to control and deflection structure for temporary deflection of the spindle path out of printing contact. Each spindle is carried by a carriage which can move radially of the carrying wheel and which is guided by a first guide member and a second guide member which cooperates with a guide groove for determining the path of the spindle carried by the carriage. Each spindle is carried such that the pressure force applied thereto during printing of an object can substantially be absorbed without moment by both guide members.

  • Patent number: 4742949
    Abstract: The invention relates to a method of manufacturing a body for a container, in which a body having a weldseam along its longitudinal direction is formed by bending material in sheet form and welding the overlapping edges of the bended material together, and the wall of the body having the longitudinal weldseam is thinned.Preferably thinning is obtained by wall-ironing. It is advantageous that the wall thickness of a wall part close to wall end of the body is larger than that of a remaining part of the body and eventually prior to thinning has been reduced and that prior to being reduced the body is provided with a gripping rim and/or cover.

  • Patent number: 4723681
    Abstract: The invention relates to a metallic container particularly for foodstuff or beverages comprising a circumferential wall, a bottom and a lid, in which container is prevailing a lower pressure than the atmospheric pressure in the filled and closed state.The invention has for its object to construct a metallic container in a manner such that the desired mechanical strength can be obtained even with a very small wall thickness and hence at very low costs of material.The invention has furthermore for its object to design a metallic container in a manner such that the probability of undersirable deformation is substantially excluded.For the above-mentioned purposes the invention provides a metallic container the circumferential wall of which has at least one zone that can be pressed inwards by the effect of the difference between the atmospheric pressure and the pressure inside the container.

  • Patent number: 4693658
    Abstract: The disclosure relates to a method of manufacturing a body formed of a shaped sheet metal blank having an opening tear strip terminating in a tongue. Overlapping edges of the blank are welded together and at the tear strip melting of a tin coating of the blank occurs so that at the tear strip the edges of the blank are linked by melted tin, or welding is completely interrupted to form a slot at the tear strip between the overlapping edges of the blank and the slot using a sealing material. Further, the disclosure relates to a metal blank for a can body having a tear strip formed there across by two weakening scores extending transversely to the edges of the blank and terminating in a tongue. The tear strip at one of the edges of the blank is provided with a covering and/or oxide layer which has a relatively low electrical conductivity.
