Compactor shoe adjustment for compressive shrinking machines

Abstract

The disclosure relates to the provision of improved and advantageous facilities for the on-line adjustment of the length of the compressive shrinking zone in a so-called two roll compactor. The compactor shoe is supported at each end, by a pair of primary levers arranged to pivot around the axis of a feeding roll. By movement of the primary levers, the tip of the compacting shoe, forming the upstream end of the compressive shrinking zone, is movable toward or away from a roller nip, formed by opposed feeding and retarding rollers and constituting the downstream end of the compressive shrinking zone. A simple, reliable and precise adjustment feature is provided, enabling the operator to easily and quickly effect precision adjustment of the position of the shoe tip, while the equipment is in full speed operation, so that the processing of materials in the compactor may be optimized. The physical arrangement of the new adjustment feature is such that, in addition to its significant functional advantages, it is readily adaptable to the structure of standard forms of equipment in the field, for on-site upgrading of machine performance.
