Abstract: A method of crushed ground-wood processing comprises charging the input between two relatively revolving and displaced conical surfaces with simultaneous dimension separation variation by circulating vibrations causing the surfaces to apply variable squeezing pressure and lateral or normal forces to effectively compress and rub the bark from the wood surface.

Abstract: A squeezing caster comprises a bed which carries a bottom plate, an intermediate carrier member, and two dies. The intermediate carrier member is of the split type. Each of the dies is mounted on a crosspiece and provided with a mechanism which drives it along the intermediate carrier member. The crosspiece is rigidly attached to said mechanism accommodated in a housing which is mounted on the intermediate carrier member. The die driving mechanism comprises a rack and four pushers. On the external surface of each pusher there is a buttress thread meshed with an internal thread of a gear whose outer teeth are meshed with the rack. One of the racks is intended for connection to a rod of a drive cylinder and provided with a link which is kinematically coupled to the other rack. The caster also contains a means for a preliminary advance of one of the dies.
