Abstract A starburst pattern die is provided for cutting starburst patterns through one or more layers of sheet stock, in the formation of package liners or pads of the sheet stock for nestably receiving fragile articles in the starbursts. The starburst is characterized by an arcuate center cut with all but one of the rays of the pattern terminating at the circumference of the cut. The arcuate piece produced by the cut is integral with the remaining ray and together these resemble a keyhole shape which is retained in the starburst pattern to preclude the need for stripping any material from the cut starburst area during manufacture. The die for this pattern consists of a radially disposed keyhole shaped knife with a partially circular cutting edge at the center of the die and a plurality of radial knives butted to the resulting partial cylindrical outer wall portion of the keyhole knife and extending outwardly therefrom, all mounted in the face of a cylindrical base block.
A PACKAGE LINER FOR FRAGILE ARTICLES, COMPRISING: SHEET STOCK INCISED WITH STARBURST PATTERNS PREDICTABLY CUT THROUGH SHEET STOCK PROVIDING COMPLETELY CUT THROUGH STARBURST PATTERNS WITHOUT WASTE MATERIAL EACH OF SAID STARBURST PATTERNS NESTABLY RECEIVING SAID ARTICLES COMPRISING A CIRCULAR PATTERN OF CONVERGENT RAYS OF SAID SHEET STOCK SEPARATED BY SUBSTANTIALLY RADIALLY DISPOSED SLOTS FORMED THROUGH THE SHEET STOCK THEREBETWEEN, ALL BUT ONE OF SAID RAYS AND THE SAID SLOTS DEFINED THEREBETWEEN TERMINATING IN ARCUATE INWARDLY FACING EDGE PORTIONS, SAID EDGE PORTIONS THEREBY DEFINING THE MAJOR PORTION OF THE OUTER PERIPHERY OF AN ARCUATE PORT THROUGH SAID SHEET STOCK AT SUBSTANTIALLY THE CENTER OF SAID STARBURST PATTERN, AND ONE SUBSTANTIALLY KEYHOLE SHAPED RAY HAVING A ENLARGED INNER EDGE PORTION CUT OUT OF THE CONVERGENT RAYS OF THE SAID STOCK CONFORMALLY SHAPED WITH SAID ARCUATE PORT, SAID ENLARGED INNER EDGE PORTION AND SAID RAYS OF EACH PATTERN BEING COMPLETELY AND PREDICATBLY CUT THROUGH WITH NO WASTE MATERIAL.
