<p>The invention relates to a device for processing flat objects (40) delivered successively in a delivery direction, in particular print shop products, and/to a continuously advanced material web (42). The device, which is to be used particularly for welding a material web, comprises at least one rigid body (90) that can be pivoted about an axis of rotation (D) and at least one tool (10) having a processing-effective zone (12), said tool being attached to said body (90) and movable along an orbit (U) by rotating the body (90). The tool is attached to the body (90) pivotally or rotatably about a pivot axis (S). The pivot position of the tool can be adjusted as a function of the rotational position of the rigid body by means of a stationary control gate and a control element interacting with said control gate and connected to the tool. According to the invention, the pivot axis (S) has a constant distance from the axis of rotation (D), wherein the processing-effective zone (12) of the tool (10) is disposed in the direct vicinity of the pivot axis (S) and the control element is disposed at a distance from the processing-effective zone (12). The invention allows the adjustment of the pivot position of the processing-active zone and simultaneous precise control of the orbit thereof.</p> |
