TITLE: METHOD AND APPARATUS FOR AUTOMATICALLY CUTTING A WEB OF FOAM MATERIAL INTO SHEETS AND FOR DISPENSING THE CUT SHEETS INVENTORS: JOSEPH J. D'ANGELO JOSEPH J. D'ANGELO, JR. ABSTRACT A web of foam material which is to be cut into sheets and then dispensed is fed to a cutting station by upper and lower draw rollers in contact with the web for drawing the web from a roll and for pulling it along a low-friction surface on a table. A cutter station has a downwardly movable knife bar carrying a knife blade and a clamp bar coupled for movement with the knife bar. The lower draw roller has its axle mounted in a pair of pivoted arms which are adapted to be depressed by a pair of presser feet mounted in a presser foot bar which is carried by the knife bar. Accordingly, when the proper length of the web has been drawn past the cutter station, actuation of the knife bar lowers the cutting blade into a grooved anvil, while at the same time moving the presser feet down into contact with the respective pivoted arms for swinging these arms down, there- by to depress the lower roller down away from contact with the web to stop drawing the web. Immediately after the drawing ac- tion is thus interrupted, the web is clamped by the clamp bar which moves with the knife bar, and then immediately thereafter cutting occurs. The table is provided with bridge-like fingers which extend downstream from the table through grooves in the movable lower feed roller. These fingers support the foam web when the lower roller is swung down away from contact with the web for interrupting the drawing action prior to its being cut. The cut sheets are conveyed through a static eliminator and then pass between staggered corrugation rolls for temporarily impart- ing effective longitudinal stiffness to the momentarily cor- rugated sheet of foam material for enabling the temporarily cor- rugated sheet to be longitudinally projected through the air for dispersing into a desired position of utility, for example such as landing in the open top of a box packed with delicate items for providing resilient padding to such items. -2-
