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.
