Abstract

A method and apparatus are provided for automatic and hands-free threading of an elastomeric mix into a calender set of rolls comprising one or more pairs of rolls that have a nip between them. A stripper roll is positioned next to one of the rolls forming the nip and is rotated so that the outer surface of the stripper roll moves in a direction opposite to the outer surface of the adjacent roll. The stripper roll removes all or a desired portion of the elastomeric mix from the adjacent roll and causes the same to transfer to another roll. Variables such as e.g., the relative surface speed of the stripper roll, diameter of the stripper roll, and distance of the outer surface of the stripper roll from the adjacent roll can be manipulated to control the amount of the elastomeric mix that is stripped by the stripper roll.

First claim

What is claimed is:

1. A calendering system for processing an elastomeric mix at a desired calendering rate, comprising:
a first roll having an outer surface and rotatable along a first roll surface direction;
a second roll having an outer surface and rotatable along a second roll surface direction that is the same as the first roll surface direction, the second roll positioned next to the first roll so as form a nip between the first roll and the second roll for the elastomeric…
