A feeder is provided for a punching or embossing apparatus. The feeder has a configuration for feeding sheets from a multiplicity of stacks. The stacks are disposed next to one another in the transport direction. In a method for punching or embossing sheets using a punching or embossing apparatus, sheets are fed to the punching or embossing apparatus from stacks disposed next to one another.

Feeder for a punching of embossing apparatus and method of operating the apparatus

A sheet punching and embossing machine includes a device for stripping waste from a punched and embossed sheet at a stripping station, the device having a stripping plate for supporting the sheet. Also included are gripper carriages fixed to revolving chains, for gripping the sheet at a leading edge thereof and for then pulling the sheet intermittently through the stripping station and further stations in the machine. The stripping plate has, in an inlet region for the sheet and before stripping openings, at least one suction opening to which vacuum is applicable from below.

Sheet punching and embossing machine

A sheet punching and embossing machine has a gripper carriage and a positioning device for the gripper carriage. The gripper carriage has grippers for clamping sheets, being fixed with limited springing to a transport chain and, by the transport chain, being movable intermittently between the processing stations. The machine further has at least one stop face on its leading side in the running direction. The positioning device contains at least one stop that can be pivoted into the movement path of the gripper carriage and is fixed to a driven pivoting shaft. A pivoting drive of the stop used being at least one electrically operated, controllable servomotor, which is connected directly to the pivoting shaft.
