SILICONE MEMBRANE SLITTING MACHINE AND METHOD

摘要

A mechanism and a method for slitting silicone membranes using automated slitting blades is presented. The pattern of slits in the membrane can be adjusted by using a cutting cylinder comprised of a plurality of circular cutting gears assembled in parallel.;The cutting cylinder is of indefinite length, but in the preferred embodiment is approximately 15″ long and 3″ in diameter. The silicone membrane can range in thickness from 0.005″ to 0.01″ inch.
