Disclosed herein is a rotary cutting system, components for the system, including a die board and a scrap ejector, and methods of assembly of the system and components. The system includes a die board including a substrate and a scrap ejector. The die board includes at least one oblong fastener receiving hole that receives a fastener to couple the die board to a die drum. The oblong shape of the fastener enables movement of the die board relative to the die drum after insertion of a plunger through a hole in the scrap ejector and into the die drum while the fastener remains within the oblong fastener receiving hole and an aligned recess of the die drum. The die board is rotatable such that the hole in the scrap ejector is no longer aligned with the plunger, preventing the plunger from exiting the die drum through the hole.

Machines and methods capable of producing diced products from a variety of materials. A stripper plate for such machines and methods has one or more slots sized to accommodate one or more circular knives of a circular cutter. The stripper plate has a base and an oppositely-disposed second surface. The slots are defined in the second surface and extend from the second surface to the base so as to define individual openings in the base. The slots are defined by multi-tiered walls so that the slots are wider at the openings thereof than in another portion of the slots.

A telescopic compression device (10) for flat bed die-cutting, stripping and part separating machines is provided, comprising a socket (12), at least one guide element (14, 15) which is slidably guided in the socket (12) and an elastic bias means (34) which biases the at least one guide element (14, 15) towards a furthest extended position and an elastic security element (44) which has an inherent stiffness and secures the at least one guide element (14, 15) to the socket (12). Furthermore, an exchange tool (2) of flat bed die-cutting machines, flat bed stripping machines or part separating machines is provided.

A material handling system is presented having a frame member and a pair of fork members that form a holding area configured to receive sheet stock therein. The sheet stock includes a plurality of parts that are connected by small tabs of material. The material handling system is used to remove the sheet stock from a cutting tool and dislodge the parts from the sheet stock by impacting the sheet stock with the fork members by rotation or movement of the forks. This arrangement eliminates the need to remove individual parts from a cutting tool, and instead allows for removal of the sheet stock and parts in a single operation thereby improving the utilization rate of the cutting tool and streamlining the manufacturing process.

A stripper clip (100) for a die board (300) of a stripping machine, the stripper clip (100) comprising: a hub (110) to be fitted into a corresponding socket (320) of the die board (300); a bridge extending from the hub (110) to a distal end (122); and a cantilevered arm (130) extending from the distal end (122) of the bridge. The clip (100) is dimensioned to fit into a socket (320) of the die board (300) with the cantilevered arm (130) extending from an underside of the die board (300) into an aperture (310) of the die board (300) for receiving waste pieces from blanks. The clip (100) is formed of a resilient material so that the cantilevered arm (130) is deflected towards the hub (110) as a waste piece (410) passes through the die board (300) and so that the arm (130) reflexes as the waste piece (410) passes the cantilevered arm (130) to assist in disposing of the waste piece (410).

The line comprises a feed path (P) of the web material (N) and, along the feed path, a transverse cutter (5) for cutting scraps (FS) from the continuous web material (N). The line includes a system for removing scraps of web material cut by the cutter. The system for removing scraps is fitted with a scrap accumulator member (21). The accumulator member (21) is movable in a direction generally parallel to the feed path (P) of the web material between: a position for receiving scraps, wherein the distance between the accumulator member (21) and the cutter (5) is such that scraps (FS) generated by the cutter (5) are collected by the accumulator member (21); and a standby position, at a distance from the cutter (5) such that scraps (FS) generated by the cutter are collected in a space (D) between the cutter (5) and the accumulator member (21).

A machine for separative machining of a plate-shaped workpiece that has: a first movement unit for moving the workpiece in a first direction (X); a second movement unit for moving a machining head for the separative machining in a second direction (Y); and two workpiece bearing faces for bearing the workpiece. A gap that extends along the second direction (Y) is formed between the workpiece bearing faces. The machine has a push-out unit having a push-out element, wherein the push-out element is movable at least in the second direction (Y) within the gap so as to press, at a predefined push-out position (AP), against a workpiece part that was cut free from the workpiece during separative machining. The disclosure further relates to methods for pushing out a workpiece part which, in particular, was cut free on such a machine.

An insert assembly is received in a recess on the outer surface of a rotary cutting cylinder. The insert has a hole for a slug ejector pin which is slidingly engagable with the insert. The hole is arranged on the insert to communicate with a through hole in the recess that extends into the interior of the cylinder. When the slug ejector pin is inserted in the pin hole, the pin proximal end is received in the recess hole adjacent to the compressible core and the pin distal end projects from an outer surface of the insert. When the pin is assembled with the insert and the insert is assembled with the cylinder, the pin proximal end operatively engages the compressible core when the pin retracts into the pin hole of the insert and the pin proximal end operatively engages the insert when the pin projects from the pin hole.

A method punches out a damper from a damper material set on a punching stage with use of a hollow punch so that the punched damper is positioned within a hollow inside of the punch while vibrating a member composing the punching stage on which the damper material is set at the high frequency. The damper material includes a viscoelastic body layer and the constraint layer laminated on the viscoelastic body layer and the viscoelastic body layer includes an attaching surface through which the damper material is detachably attached on the liner.

A method for manufacturing a material strand assembly for a vehicle. The method includes: extruding strand material in an extruder so that an extruded material strand is produced; monitoring the quality of the extruded material strand so as to detect faults of the extruded material strand; in case of a detection of a fault, cutting out the fault from the material strand and re-joining cutting end faces, thus producing a joint, so that a faultless material strand is produced. The cutting-out step is conducted such that any two adjacent joints are at a minimum joint distance from each other. The faultless material strand is stored in a storage unit so as to produce the material strand assembly. The extruded material strand is passed through a first strand accumulator between the extruder and the cutting arrangement and through a second strand accumulator between the cutting arrangement and the storage unit.
