<p>A web processing machine permits slitting of a wide range of highly extensible materials with low Young's modulus of elasticity characteristics. The slitting function may be carried out under low elongating tensions while yielding highly accurate and repeatable width dimensions in the finished product. The machine incorporates a resiliently coated cylinder with extremely sharp and narrow rotating blades which are commonly adjusted into close contact with the coated cylinder. The blades are driven so that their peripheries slightly over-speed the web as it enters the first contact point of the coated cylinder and the blades as they rotate.</p> |
