Abstract
A system and method for efficiently removing and disposing of a continuous web of matrix waste formed during the high speed manufacture of adhesive backed, pressure sensitive label stock on a printing press. As it leaves the press, the web of matrix waste is formed into a generally tubular rope in a cylindrical eductor. A controlled mixture of a high volume, high air and oil is used to pass the rope of matrix waste through an eductor, into and through a flexible hose, and into a compactor where the rope is compacted into relatively compact bundles. These bundles can then be readily deposited and efficiently stored in waste receptacles.
