A continuous punching method comprises: providing a sheet material, applying a first punching process of a first punch station to the sheet material, and applying a second punching process of a second punch station to the sheet material. The first punching process includes: adjusting a punching depth of a punch blade of the first punch station to determine a lateral length to be punched out by the punch blade, and forming two longitudinally spaced apart first punched slits on the sheet material through the punch blade. The second punching process includes: adjusting lateral positions of two punch blocks of the second punch station, and forming two laterally spaced apart second punched areas on the sheet material through the punch blocks. The two first punched slits and the two second punched areas communicate with each other to form a contour of a combined cut-out.

A method for contour punching an output stack consisting of sheet-like material and a punching device for carrying out the method Includes providing at least two punching procedures. A large proportion of an unprinted region is separated from a printed region in a first punching procedure and a first punching waste produced thereby is collected separately, whereby the quantity of the second punching waste which is formed in a second punching procedure is significantly less than if only a single punching procedure were to be carried out. By collecting the first punching waste and the second punching waste separately, it is possible to provide this waste in each case for appropriate disposal or appropriate recycling.

A punching/perforation machine for creating a punching/perforation pattern in a material unit/web comprises a punching/perforation tool that includes an upper tool part which can be moved in a direction of stroke and which includes a plurality of punching dies/perforation needles arranged in a predefined grid in a transverse direction. It can be moved by a pressure beam that is operatively connected to a drive unit via a control device in order to produce a punching/perforation stroke. The material unit/web being supplied between the upper tool part and a stationary lower tool part/female die. Means are provided for generating a simultaneous movement of the material unit/web relative to the punching/perforation tool by a predefinable distance both in the direction of travel and in the transverse direction such that the material unit/web can be placed in a different predefinable position relative to the punching/perforation tool prior to each punching/perforation stroke.

A film cutting apparatus includes: a punch plate including a first punch protruded on an upper surface and a second punch protruded on a lower surface; a first die plate having a first hole corresponding to the first punch, the first die plate providing a surface on which a film is provided; a second die plate having a second hole corresponding to the second punch, the second die plate providing a surface on which a film is provided; at least two guide bars penetrating the first die plate and the punch plate and fixed to the second die plate; a first elastic member between the first die plate and the punch plate; a second elastic member between the punch plate and the second die plate; and an elevator configured to press the first die plate.

A notching machine (1) for making a paper blank from a corresponding paper sheet comprises: a frame (10); a supporting surface (S) defining a worktop (P); a carriage (132), movable in parallel with the worktop (P); a primary cutting unit (141A), associated with the carriage and including a primary blade (141A) and a primary anvil (141A) slidable relative to each other along a cutting orientation (C) perpendicular to the worktop (P) to make a primary shear cut (T1); a secondary cutting unit (142A), associated with the carriage (132) and including a secondary blade (142A) and a secondary anvil (142A), slidable relative to each other along a cutting orientation (C) to make a secondary shear cut (T2); an actuating assembly, configured to move the primary blade (141A) relative to the primary anvil (141A) and the secondary blade (142A) relative to the secondary anvil (142A) along the cutting orientation (C).

The present disclosure relates to the technical field of punch, in particular, to a real-time control apparatus for punch. The real-time control apparatus of a punch includes an upper seat, a middle seat and a base. Its bottom of the upper seat is provided with a lifting seat connecting with an oil cylinder; the upper seat is provided with a driving mechanism, which connects and drives a slider to move towards the base to close to its bottom dead centre of the slider, the oil cylinder is activated, pushing the lifting seat to raise a H distance, thereby lifting the upper seat the H distance. The slider is also raised the H distance so as to compensate the H distance falling due to the inertia of the slider, so that the slider stops at its bottom dead centre.

A film cutting apparatus includes: a punch plate including a first punch protruded on an upper surface and a second punch protruded on a lower surface; a first die plate having a first hole corresponding to the first punch, the first die plate providing a surface on which a film is provided; a second die plate having a second hole corresponding to the second punch, the second die plate providing a surface on which a film is provided; at least two guide bars penetrating the first die plate and the punch plate and fixed to the second die plate; a first elastic member between the first die plate and the punch plate; a second elastic member between the punch plate and the second die plate; and an elevator configured to press the first die plate.
