In an example, a clamp may include a chassis, a swingarm disposed on the chassis, a clamp wheel disposed on a first end of the swingarm to engage with a drag portion of the chassis, and an auxiliary bias member to exert a force against the clamp wheel to resist a rotation of the clamp wheel. The force may periodically increase in magnitude.

A method for feeding a web of printing material in a manufacturing system for producing packages, includes feeding the web from a web-fed printing press to a flat-bed machine for die-cutting or embossing while the printing press is in operation. An inserting device is used for winding the web onto an auxiliary wind-up device, moving a web-guiding element having a roller in a compensatory manner to achieve a temporary standstill of the web by converting a continuous movement of the web into an iterative movement by changing a speed of the web through changes of position of the roller, clamping the web while being cut by using a clamping unit, cross-cutting the web creating a cross cut edge by using a cutting unit adjacent the clamping unit, and inserting the web, cross cut edge first, into the flat-bed machine for at least one of die-cutting or embossing.

A method of gripping a substantially planar workpiece while providing compensation for variations in thickness is described. During the process, the workpiece is overdriven into a clamping member before clamping force is applied, and the positions of the clamping member before and after application of the clamping force are measured. These measurements are then used to control a compensating movement of the tooling table and optionally a final lift of the conveyance rails.

Machinery and techniques are disclosed for applying treatment processes to surfaces of objects arranged in a form of an array of objects, and for inspecting surface areas of the objects in such object arrays before and/or after applying the surface treatment processes thereto.

Machinery and techniques are disclosed for applying treatment processes to surfaces of objects arranged in a form of an array of objects, and for inspecting surface areas of the objects in such object arrays before and/or after applying the surface treatment processes thereto. The treated objects are held by an array of grippers/mandrels, each gripper/mandrel is configured to receive a respective object of the array, and to controllably generate gripping contact with internal surface(s) of the received object, for attaching the object thereto. A gripper of some embodiments comprises a body assembly configured to be at least partially received inside the object and comprising a hollow part extending along a length thereof, one or more friction imparting elements located in or on the body assembly and configured to change between an engaged state in which contact with inner surface of the object placed over the gripper is established therewith, and a released state in which there is no contact with the inner surface of the object, and an attachment mechanism configured to cause the one or more friction imparting elements to engage the inner surface of the object when said object is placed over the gripper.
