The invention relates to a die for cutting a shape or pattern from a material, the die being composed of a base plate (1) comprising an upper surface (2) and a lower surface (3). The die comprises one or more raised edges (4) in the form of a pattern or shape to be die-cut or embossed, on each of the upper and lower surfaces, such that the die can be used to die-cut or emboss two sheets of material simultaneously.

A first sheet panel is folded along a first fold line, and thereby a first folded part is formed in the first sheet panel. Subsequently, the first folded part is folded back along a second fold line, and thereby a folded-back part is formed in the first sheet panel. A corner cut device cuts a second sheet panel and the folded-back part to form corner cut parts. At this time, the corner cut device prevents the first folded part and a base part of the first sheet panel from being cut.

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.

[Problem] To make it easy to attach a counterplate to a specified position on a cutting plate, to prevent the counterplate falling from the cutting die during blanking, and to prevent the counterplate from making contact with a sheet. [Solution] The present invention includes: a housing (2) which includes a hole-side inclined portion (21), and in which an accommodation hole is formed; an engaging means (3) which alternates between a lower lock and an upper lock in the housing (2); and a sliding shaft member (4) fitted in the housing. The inside diameter of the upper side of the hole-side inclined portion (21) is larger than the inside diameter of the lower side thereof. The engaging means (3) is disposed above the hole-side inclined portion (21). In the sliding shaft member (4), the following are integrally formed: a lower-side inclined portion (42) which is disposed above a protruding part that protrudes below the housing (2), and which has the same direction of inclination as the hole-side inclined portion (21) and a different angle of inclination thereto; and a middle inclined portion (43) which is disposed above the lower-side inclined portion (42), and which has the opposite direction of inclination to the hole-side inclined portion (21). When the sliding shaft member (4) is pulled downwards and is stopped at the lower limit position, the lower lock state is engaged, and when the sliding shaft member (4) is pushed upwards and is stopped at the upper limit position, the upper lock state is engaged.

A multi-cavity mould (1) for a thermoforming machine used in the process of high-volume, continuous thermoforming of a plurality of thin-gauge plastic products (2) from a preheated thin-gauge thermoplastic sheet (3) comprising an upper tool (11) and a lower tool (12) arranged in a cooperating manner; the lower tool (12) comprising a plurality of cavities (8) in which cavity moulds (8) are placed and a plurality of base plates (91) from which a plurality of supporting blocks (92) extend perpendicularly over a predetermined total height (a), situated between adjacent cavities (8), each of said supporting block (92) has a stepped profile comprising three substantially rectangular shaped zones (92a, 92b, 92c) and a fourth substantially isosceles trapezoid shaped zone (92d) in a vertical cross section, having a common symmetry axis.

The invention relates to steel-rule cutting dies having a die block with at least one kerf configured to receive a corresponding steel-rule intended to be partially inserted into the kerf. The die block also has at least one element having magnetic properties, such as for instance a magnet, located or embedded in proximity to each kerf for providing a magnetic field that retains the steel-rule when the steel-rule is received into the corresponding kerf. The presence of the magnetic element(s) in proximity to the kerf(s) allows maintaining the corresponding rule(s) in position within its kerf even if the kerf is cut “loosely”. The corresponding rule may be quickly and easily inserted and accurately maintained even if the die block expand or retract under atmospheric variations. Among other advantages, the invention allows better stability of the cutting-die, faster leveling on press, and increased the number of re-knifing and longer run-time.

An anvil is configured to operatively engage with a tooling agent. The anvil includes an outer surface, an opposing surface opposite the outer surface and an inner surface. One or more spring elements are disposed between the opposing surface and the inner surface. The springs provide a compliance to the anvil.
