A can body is fitted to an inner shaping tool rotatable adjacent a freely rotatable outer shaping tool outside the can body. An arm having an outer end rotatably carrying the outer shaping tool and an inner end is pivotal about its inner end. The inner tool and the can body fitted thereto are rotated to entrain and rotate the outer tool. A motor controlledly pivots the arm and thereby moves the outer shaping tool toward and away from the inner shaping tool. A position detector connected to arm senses the angular position thereof and the relative spacing of the inner and outer tools. A controller including a memory controls the motor in accordance with a sensed angular position of the arm.

A method and apparatus for producing can bodies, wherein blanks are laterally centered after removal from a magazine, are engaged in the center of their rear edge and are transported into a shaping station in which initially the center section of the blank is bent into its final shape. While doing this, a central force and friction lock is produced between a transporting means and the deformed blank to realize reliable guidance of the already partially bent blank. To further transport the blank, it is contacted at its rear edge in the already completely bent region by two lateral transporting devices and is advanced to a seam forming station, while the opposite longitudinal edges of the blank are brought to an adjoining relationship.

A conveyor apparatus for sequentially advancing articles in a conveying direction comprises two parallel-spaced flexible pulling elements, each trained about an upstream and a downstream end wheel. A plurality of parallel-spaced article advancing bars, each oriented perpendicularly to the conveying direction, are supported by the two pulling elements and extend continuously therebetween. A stationary article supporting surface extends from between the first end wheels parallel to the conveying direction for supporting the articles as they are pushed in the conveying direction by respective article advancing bars. The article supporting surface has a starting location adjacent the upstream end wheels for sequentially receiving the articles to be engaged by an article advancing bar. The starting location is positioned relative to the upstream end wheels such that the article dwelling in the starting location is abutted by the article advancing bar at a moment when an imaginary plane passing through the article advancing bar and containing the rotary axes of the upstream end wheels defines, with the conveying direction, an angle of 45.degree. at the most, whereby a velocity component of the circumferential velocity in the conveying direction is at the most 71% of the circumferential velocity at the moment of contact between the article advancing bar and the article dwelling in the starting location.

To make a container with a butt welded longitudinal seam, the side edges of a preformed blank are guided by straight grooves so that the side edges converge at an acute angle. At the point of convergence the side edges are heated to at least to the forging temperature, preferably by a focused laser beam. The side edges are then tangentially compressed before they cool.

Method and apparatus for producing a container body having a butt welded

Method and apparatus for laser-beam welding of longitudinal seams in container bodies feature overlapping longitudinal ends of a metal sheet, the length of the transverse ends of which exceeds a predetermiined circumferential dimension for the container body, into such a position relative to one another that they form an acute angle and define an angular opening, and the edge of one longitudinal end is oriented toward the inner face of the other longitudinal end. At least one focused laser beam, which is capable of relative movement with respect to this angular opening and parallel to the longitudinal ends, is aimed into the angular opening and locally melts portions of the longitudinal ends. The locally-molten longitudinal end portions are pressed against one another before they drop below the welding temperature to form a welded longitudinal seam.
