ABSTRACT:
A compensator is used with a machine frame having a pair of ends, a first mold half secured to one of the frame ends, a second mold half movable along an axis toward and away from the first mold half, and an actuator braced against the other frame end and having an outer end operatively engageable with the second mold half for pressing the second mold half axially against the first mold half. The compensator has an element secured on the second mold half and another element secured on the actuator outer end together forming a substantially closed chamber. The two elements are displaceable axially and tippable relative to each other. A multiplicity of relatively displaceable and substantially incompressible metal balls fills the chamber.
