Abstract: 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.

Abstract: The invention relates to a device for reshaping and/or folding bodies of cans (11) by means of two shaping tools (12, 13) which rotate in opposite directions. One of said shaping tools is arranged on a lever (14) such that said shaping tool can be radially displaced. The lever is connected to a controllable actuator (15, 16, 17).

Abstract: The invention relates to an apparatus for spreading and shaping can bodies, having a pin-like shaping tool that is forced from one end into the can body to be widened and a counter tool.

Abstract: A knife holder unit combined with a rotary knife pair includes a frame composed of an upper frame part and a lower frame part; and an upper and a lower knife holder assembly supported in the upper and the lower frame part, respectively. Each knife holder assembly includes a bearing shaft composed of a first bearing shaft part having a longitudinal axis and an adjoining second bearing shaft part. The first bearing shaft part is received in a recess of a respective frame part for turning motions therein about the longitudinal axis. A first securing arrangement immobilizes the first bearing shaft part relative to the respective frame part. A rotary bearing surrounds the second bearing shaft part and has a rotary axis which is offset relative to the longitudinal axis to define an eccentricity therewith. A rotary knife is mounted on the rotary bearing.

Abstract: An apparatus for flanging an edge of a can body includes a flanging tool which has an inner tool part having an outer circumferential flanging face for engaging an inner surface of a circumferential edge zone of the can body; an outer tool part surrounding the inner tool part and having an inner circumferential abutment face surrounding the flanging face for abutting a periphery of the can body edge during flanging of the can body edge by the flanging face; an axially hollow, non-rotatable spindle to which the outer tool part is affixed and which has a first axis; a rotary shaft received in the spindle and having a second axis coinciding with the first axis; and a shaft stub affixed to and extending from the shaft. The inner tool part is rotatably mounted on the shaft stub which has a central, third axis disposed at an inclination to the second axis.
