A post-processing apparatus includes: a moving mechanism configured to move a punching apparatus in a width direction orthogonal to a transportation direction of a sheet; and a sensor configured to optically detect a mark formed on the sheet and indicating a position to be punched. The mark is configured such that an interval in the transportation direction between a plurality of feature portions extending in the width direction is configured to be changed depending on the width direction. The moving mechanism is configured to determine a position of the punching apparatus in the width direction based on a difference between respective timings of detection of the plurality of feature portions.

The invention concerns a stamping tool with a tool upper body, an intermediate plate, at least one stamping unit, in particular several stamping units, a tool lower body to guide the stamping unit and at least two guide pillars to guide the tool upper body relative to the intermediate plate, which are solidly connected to the intermediate plate, wherein the guide pillar is arranged eccentrically and the stamping unit has a stamping punch and a stamping die separate from the stamping punch, the stamping die being operatively connected with the tool upper body.

A cutting unit for cutting preparation features in a web of sheetlike material is provided. The cutting unit has a first part with a rigid base portion, at least one first cutting tool configured to cut a first preparation feature in the web of sheetlike material, and at least one second cutting tool configured to cut a second preparation feature in the web of sheetlike material. The at least one first and second cutting tools are attached to the base portion and located at a distance from each other, wherein at least one of the at least one first or second cutting tools is supported by a flexible support that is located in the rigid base portion of the first part.

A recording system includes an ejecting unit, a punch unit, and a control unit. The ejecting unit ejects ink onto a sheet transported by a transport unit to form an image. The punch unit forms two through holes aligned in a Y direction with respect to the sheet. The control unit controls ejection of the ink based on image data. When the two through holes are formed in the sheet, the control unit divides a region where an image can be formed into a first region and a second region that is aligned with the first region in a T direction and in which the two through holes are formed. The control unit causes the ejecting unit to eject the ink to form a part of the image in the first region, and causes the ejecting unit not to eject the ink in the second region.

A separating system for separating individual container products from a frame assembly of plastic material, particularly polypropylene, has at least one stamping device (36) that at least partially separates the respective container product from a frame waste. By the stamping device (36) including a free fall body (52) separating the respective frame waste from the associated container product from an initial position during free fall, the separation can be carried out with very high speed (free fall) and additional mechanical components for applying a constraint force on the stamping body during the creating of the separating line can be omitted.

The present disclosure relates to a punching cell for punching holes in workpieces, the cell comprising an industrial robot comprising a base, a wrist and at least four robot axes between the base and the wrist; a tooling comprising a frame to be detachably attached/mounted to the wrist axis of the industrial robot, an ultrasonic puncher tool mounted on the frame, a die mounted on the frame and aligned with the puncher, and a servomotor configured to drive the puncher tool towards the die; the cell further comprising a support fixture to position the workpiece to be punched, and a control unit to control the operation of the industrial robot to punch a hole in the workpiece.

A filter support sheet extruded from a fluoroplastic material includes a base section having spaced-apart ribs extending outwardly from at least one surface thereof. Segments between spaced-apart ribs provide flow channels and apertures are punched through the sheet in a predetermined pattern unaffected by the structure of the support sheet. A method includes the steps of: (1) extruding a thermoplastic, fluoroplastic material to form of a sheet; (2) passing the sheet through a nip region provided by opposed rollers; at least one having an outer surface with counter-sunk grooves. Counter-sunk grooves in one roller are aligned with an outer surface or counter-sunk grooves of the other roller in the nip region to form a ribbed sheet having ribs upstanding from at least one surface of said sheet; (3) setting the ribbed sheet and (4) punching apertures through the ribbed sheet in a predetermined pattern.
