In some embodiments, apparatus and methods are provided for improved handling of lithography masks including a mask inverter that includes a first contact pad dedicated to inverting masks that have not been cleaned; a second contact pad dedicated to inverting masks that have been cleaned; an actuator coupled to the first and second contact pads and operable to invert the first and second contact pads; and a controller coupled to the actuator and operative to control the actuator. Numerous other aspects are provided.

A sheet-transporting drum includes sheet-supporting areas each being formed of a first comb segment and a second comb segment having segment teeth. At least one of the comb segments is rotatable for adaptation to a sheet format. A mechanical leading-edge gripper is provided on the first comb segment and a pneumatic trailing-edge gripper is provided on the second comb segment. A mechanical trailing-edge gripper is additionally disposed on the second comb segment and is deactivatable in particular by format adjustments. This advantageously allows either the trailing edge of a sheet to be securely held down mechanically or a full-bleed print to be applied to the sheet when the trailing edge of the sheet is held down pneumatically. A sheet-fed printing machine is also provided.

A gripper arrangement for lifting a flexible semi-finished product from a support, wherein the gripper arrangement comprises a flexible semi-finished product resting on a support and at least one pair of grippers with a suction gripper or needle gripper and with at least one clamping gripper, wherein the suction or needle gripper is pivotable around an axis between a pick-up position for picking up an edge of the flexible semi-finished product and a transfer position for transferring the edge of the flexible semi-finished product to the clamping gripper. Furthermore, a corresponding method is described.

A shoe cover dispenser device for installing a plurality of shoe covers includes a frame, an installation assembly installed on the frame, and the locking assembly installed on the frame and is capable of locking the installation assembly, so that the installation assembly can facilitate the installation of the shoe covers on or the removal of the shoe covers from the installation assembly.
