Most waste in the nonwovens industry is generated during web consolidation and conversion in the form of edge trims, bad rolls, and off cuts. There are two basic methods of reopening waste in nonwovens manufacture. For on-line continuous processes, one cylinder openers are used. The material is fed between a wired feed roll and a dish to a wired opening roller. The opened fibers are blown back to the beginning of the line and mixed with virgin stock. Laroche manufactures three sizes of such openers: minitrim(200 millimeters), supertrim(500 millimeters), and hypertrim (1000 millimeters). In off-line batch processing, waste are collected and taken to a central waste processing line of 500, 1000, or 1500 millimeter width for cutting, feeding, opening, and baling.
