A process for producing a resinous panel which is for use as at least some of the front panel of an article, the process including (A) a step in which a resin sheet having a thickness of 0.5-10 mm is fixed to a working table and (B) a step in which the resin sheet is punched out by forcing a Thomson blade into the resin sheet approximately perpendicularly thereto from the side where the surface of the resin sheet is to be the outer surface of the article, thereby obtaining the front panel, wherein (C) the Thomson blade is a double-edged blade having an edge angle of 30-60 degrees. The resin sheet has a tensile modulus of preferably 1,500 MPa or greater. Preferably, the resin sheet includes a transparent resin sheet layer and a colored resin sheet layer in this order from the surface that is to be the outer surface of the article. The colored resin sheet is one which does not break when a DuPont impact test was conducted in accordance with ASTM-D2794 in a 0° C. environment under the conditions of a height of 50 cm, an impactor diameter of 1 inch, an impactor weight of 1 Kg, and a pedestal diameter of ½ inch.

A sheet material processing unit (20, 22, 24) comprises a transport system (32) for transporting sheets (12) or parts thereof from a respective input end (20i, 22i, 24i) to a respective output end (20o, 22o, 24o). A gripper unit (46) is releasably coupled to the transport system (32) and is configured for holding at least a part of one of the sheets (12). Additionally, at least one handover mechanism (47d, 47r) is provided being configured for decoupling the gripper unit (46) from the transport system (32) and providing the gripper unit (46) to a neighboring sheet material processing unit (20, 22, 24) and/or receiving a gripper unit (46) from a neighboring sheet material processing unit (20, 22, 24) and coupling the received gripper unit (46) to the corresponding transport system (32). Additionally, a sheet material processing machine (10) is presented which comprises at least two such sheet material processing units (20, 22, 24).

A puncher capable of fast and accurate positioning is provided, which includes a cutter unit, a pressing plate, a bottom seat and magnetic attracting units. The cutter unit, a pressing plate and the bottom seat are each provided with magnetic attracting units. The cutter unit is attracted on the bottom seat, and the pressing plate is attracted on the bottom seat, for clamping the object to be punched between the pressing plate and the bottom seat. The present application has the beneficial effects that the pressing plate is arranged between the cutter unit and the bottom seat, and the magnetic attracting units are arranged on the cutter unit, the pressing plate and the bottom seat, such that the object to be punched can be quickly clamped for being accurately drilled, and the cutter unit, the pressing plate and the bottom seat can be easily assembled and disassembled.

The invention relates to a method for cutting up punching scrap running as waste from a punching device, in particular from a fine blanking press, by means of a waste-cutting device, in particular which is arranged as a progressive tool with respect to the punching device, wherein, by way of the waste-cutting device, the punching scrap is completely cut through perpendicularly to the running direction thereof at a cutting edge by a cutting knife and in this way punching-scrap portions are formed, wherein, together with the stroke of the cutting knife, at least one scrap web of the punching scrap that is spaced apart from the punching-scrap boundaries is cut through by at least one punch which is spaced apart from the cutting knife, preferably by at least two punches, in particular so that each punching-scrap portion is subdivided into at least two punching-scrap sub-portions. The invention also relates to a waste-cutting device of a punching device, comprising a cutting knife and a cutting edge, wherein, by way of the interaction of cutting knife and cutting edge during a stroke of the cutting knife, punching scrap which can be passed through between cutting knife and cutting edge in a running direction can be completely cut through perpendicularly to the running direction, in which, spaced apart from the cutting knife, provision is made of at least one punch which is arranged in a locationally fixed manner with respect to the cutting knife and which can be moved together with the cutting knife, in particular by way of which at least one scrap web of the punching scrap can be cut through in the punching scrap.

A thermoforming packaging machine includes a forming station for thermoforming troughs in a film web, a filling path for filling products into the troughs, a sealing station for sealing the troughs, a chain guide for guiding a transport chain for the film web, a transverse cutting device for cutting the film web in a direction transverse to the transport direction, a longitudinal cutting device for cutting the film web in the transport direction, and a control device for controlling processes running on the thermoforming packaging machine.

In a method of operating a flat-bed die-cutter a printing substrate in the form of a web is fed to a die-cutting module of the flat-bed die-cutter, a web section is severed from the web and removed as waste. The web is guided through the die-cutting module and the web section is severed from the web in or downstream of the die-cutting module and removed as waste. Products are thus formed by die-cutting a web while reducing waste and periods of standstill.
