METHOD AND APPARATUS FOR REPROCESSING MATERIALS, PARTICULARLY, THERMOSETTING PLASTICS Russian patent published in 1995 - IPC

FIELD: reprocessing of polymeric materials. SUBSTANCE: method involves feeding components under equal pressure through pipelines, with pipelines being formed as hoses so that pressure of first component acts upon second component feeding hose extending along at least a portion of path leading to mixing chamber within first pipeline. Apparatus for reprocessing of materials, for example thermosetting plastics, has pipelines formed as hoses for feeding components under practically the same pressure for regulation of pressure of second component. EFFECT: increased efficiency by equalizing pressure in hoses in the process of feeding components to extrusion head. 3 cl, 2 dwg
