  • Two-part die for producing sheet material incorporating smaller areas defined by elongated slits and means of attachment
    Patent number: 5298010
    Abstract: In one aspect, an article of manufacture constituting a flat planar sheet of material having slits cut therethrough in selected patterns to define the configuration of a subsidiary portion of the flat planar sheet of material, while means of attachment are provided at each change of direction of the perimeter of the subsidiary portion of the sheet. Formed in the flat planar primary sheet of material are lines of flexibility formed by linear compression over a very limited area of the flat planar sheet of material to diminish its thickness along the lines of fexibility thereby permitting flexure of the planar sheet of material along the lines of flexibility.
    Type: Grant
    Filed: May 19, 1993
    Date of Patent: March 29, 1994
