ABSTRACT:
The ejector operating mechanism includes an ejector cylinder and an ejector piston, with the ejector piston extending through an adjusting bush and being fixedly connected thereto. An internally threaded sleeve is mounted in the cylinder for movement axially thereof while being fixed against rotation, and abutments engage with the sleeve to limit the axial movement thereof. The adjusting bush is threadedly engaged in this sleeve whereby the axial position of the sleeve relative to the bush can be varied by rotating the ejector piston, to determine the stroke of the ejector piston.
