An apparatus for perforating a panel of material comprising a driver assembly; a perforation assembly comprising a cutting edge for cutting the panel of material; an impacting surface moveable with respect to the cutting edge; and, means for holding the panel of material in a material plane between the cutting edge and the impacting surface, wherein the driver assembly is arranged to drive the cutting edge through the material plane into the impacting surface to cut the panel of material.

A paper-made staple binds a sheet bundle subjected to folding processing by a folding blade and a folding roller. The paper-made staple includes a pair of leg portions inserted into the sheet bundle and then bent inward; and a connection portion that connects the leg portions in a staple longitudinal direction. The connection portion has, at an edge portion thereof, a cut in a direction crossing the longitudinal direction so as to correspond to a predetermined folding position of the sheet bundle for the purpose of facilitating the folding of the connection portion, and the cut is formed inward from the edge portion so as to have a substantially triangular shape and is provided on both edge portions of the connection portion of the paper-made staple.

A Carl punch system for a vehicle seat cover. A guide (104) is installed above the upper surface of a base (102). A controller (106) is installed on the outer surface of the base (102) to control the Carl punch system according to a predetermined program. A Carl punch means (108) is disposed on the central upper surface of the base (102) to punch a seat cover to produce vent holes with a pattern desired by a user in the seat cover. A press (110) is vertically slidably installed on the guide (104) and electrically connected to the controller (106) so as to press the Carl punch means (108) disposed on the central upper surface of the base (102) according to a control signal from the controller (106). The Carl punch system has improved productivity and workability.

The present invention relates to a cutting tool (100) for providing holes in a core material layer (10). The cutting tool (100) comprises a cutting knife (110) having a cutting edge (112) configured to cut through the core material layer (10), and a support structure (120) onto which the cutting knife (110) is attached, wherein the support structure (120) is at least partly formed by an elastic material.

An apparatus (10) and a method are described for producing a closing system (100) for containers comprising an anti-tampering strip (101) configured to be attached to an opening of a container, and a re-closable closing body (102), configured to hermetically close said containers. The apparatus (10) comprises a welding and deformation station (11) in which it is provided to weld a barrier element (108) to the re-closable closing body (102) and to fold a flexible annular portion (109) of the anti-tampering strip (101) back toward the inside of the closing system (100) while the latter is stationary in a same predetermined position in the welding and deformation station (11).

A method for realizing articles having a predetermined area and aesthetic appearance uses frames to each of which a portion of material having a prevalent flat extension can be removably hooked. The method includes stitching or punching operations and cutting operations implemented on each portion of material in a first station, a second station and a third station sequentially. Cutting operations are executed on a first portion of material hooked to a first frame in a third station, while stitching or punching operations are carried out on a second portion of material hooked to a second frame and punching or stitching operations are performed on a third portion hooked to a third frame situated in the first station in phased relation.
