Abstract: In the method for production of scored punched parts from a material sheet by a punching and scoring tool the formation of scores in the material sheet is started before the punching process is initiated. The punching and scoring tool has a carrier board, on the underside of which punching elements and scoring elements are provided, and a punching/scoring plate under the carrier board, in which scoring grooves are formed under the scoring elements. The scoring elements in an initial position, in which the scoring elements and punching elements are arranged at a distance from the punching/scoring plate, project further from the carrier board towards the punching/scoring plate than the punching elements. The scoring elements are also mounted flexibly on the carrier board in the lifting direction.

Abstract: The punching and scoring tool produces scored punched parts from a material sheet and has a carrier board, which is provided on its underside with punching elements and a scoring plate, on the underside of which scoring projections are arranged. A punching/scoring plate, in which scoring grooves are formed under the scoring projections, is provided under the carrier board. Leveling bushes are provided in the carrier board and bear against the scoring plate to provide an accurate supporting plane for the scoring plate.

Abstract: An embossing set-up system is disclosed for setting the position of at least one embossing die on the working side of a working die plate, in which system the embossing die features through holes extending perpendicularly to the working side of the die plate, and through which holes extends a threaded element. Each such threaded element is provided with a threaded shank and a head, the free end of the shank engaging a tapped hole in the die plate, and the cross section of the head being larger, and the cross section of the threaded shaft being smaller, than the cross section of the relevant through hole.

Abstract: A device for removal of knockouts from a material sheet has a support plate for the material sheet having openings with continuous vertical walls. Each knockout overlaps the pertaining opening resting with its marginal bearing surfaces on the support plate. Knockout tools with vertical and horizontal narrow sides on a tool holder plate movable toward and away from the support plate are so arranged that their disposition is essentially vertical to the coordinated knockout and symmetric as regards the bearing surfaces. Each knockout tool on its support plate side features at least one point as an end of the one vertical narrow side. The angle between the point and the face extending from the point to the adjacent horizontal narrow side ranges from 20.degree. to 50.degree. projected in the side center plane.
