Abstract

A material guide jaw, for two co-operating rolls of a rolling mill or calender, particularly for processing rubber or synthetic plastics material, comprising a jaw plate which forms a guide for the material and is so mounted on an intermediate plate which is mounted on a base plate that the jaw plate can be adjusted in three different ways while remaining in the same plane. Thus the base plate is displaceable at right-angles to the plane of the axes of the two roll spindles and carries a pivot shaft which is so secured in bearing lugs on the base plate as to prevent longitudinal displacement of the pivot shaft; the intermediate plate is mounted on the pivot shaft and is longitudinally movable thereon for adjustment in a direction transverse to the direction in which the base plate is displaceable; and the jaw plate, one face of which forms the guide surface for the material which is to be processed in the rolling mill or calender, is mounted on the intermediate plate for rotation with respect to the intermediate plate about a pivot axis located at a middle part of the intermediate plate and extending perpendicular to the plane of the intermediate plate.
