    Abstract: In a method and apparatus for cutting expanded graphite sheet material, at least one cutting tool is urged against the sheet(s). The cutting tool has at least one ridge extending therefrom, that includes a substantially tapered cross-section having sloping sides and an edge surface. At least a portion of the sheet material is displaced as the ridge is urged against the sheet. A region of the sheet material in contact with the ridge is compressed so that the density of the region reaches or exceeds the breaking density of the sheet.

    Abstract: A method for cutting openings in a sheet of thermoformed containers. The sheet of containers is indexed into a cutting assembly. The cutting assembly includes a shear plate having a plurality of openings formed therethrough, and having an upper surface which defines a cutting plane. A locating means including a plurality of anvils is raised so that the anvils enter the containers and raise the sheet toward the shear plate. The end portions of the containers are located within the openings of the shear plate, and a portion of the containers is positioned in the cutting plane. The cutting assembly includes a blade mounted on piston/cylinder assembly for sliding movement along the upper surface of the shear plate. The cylinder is actuated to move the blade along the cutting plane. The blade cuts off the portion of the containers and creates an opening in the containers.

    Abstract: When a blank is cut from metal sheet which suffers from crystallographic anisotropy, there is a tendency for ears to be formed during subsequent forming operations, such as drawing or pressing. In order to compensate for this tendency, there may be used a metal blank which is not completely round, but has lobes at positions to cancel at least some of the valleys between the ears. There is described a punch and die which may be used to form such a lobed blank. The punch has four circumferentially extending lobe-forming sections. Each lobe-forming section is constructed by forming a stepped recess in the cutting edge of the punch. In each lobe-forming section, the depth of the recess varies from a maximum at the middle of the section to zero at the ends. The die is conventional.

    Abstract: A pair of rotary dies with lands having coacting cutting edges which cut blanks of material from a web passing between the rotating dies. To provide a clean cut and improved squareness of the cut ends, a side face of the land adjacent the cutting edge has a positive rake. To insure that the cutting edges can be brought into coacting relationship to produce a clean cut, they are located and arranged on the dies so that they can be varied and adjusted axially and in rotary phase relationship to each other. A die stand for positioning, adjusting and driving the rotary dies, and a method for making negative electrode cylinders for producing the rotary dies by hardening, grinding and electric discharge machining blank cylinders of tool steel, are also disclosed.

    Abstract: A process and apparatus for cutting, creasing and/or embossing sheets of cardboard, paper of similar material is disclosed. The apparatus includes a tool plate or die having steps therein in the form of parting steps and ribs and/or grooves to form creases. A resilient elastic member is employed to press the cardboard web down against the various steps in the tool plate. The size and configuration of the steps and the tool plate causes severing or cutting of the cardboard or creasing or embossing. Apparatus for use with rotational as well as planar or reciprocating blanking machines and a variety of different tool plate constructions are disclosed. The process includes resilient urging of the sheet against the die piece with the elastic member causing deformation of the sheet to conform to the tool plate.
