EXTRUDER WITH SEVERAL SHAFTS Russian patent published in 2010 - IPC B29C47/60 

FIELD: machine building.

SUBSTANCE: extruder with at least two, allowing parallel axis drive shafts, on which by means of connection shaft-bushing there are put without ability of turning feeding and/or working nozzled components, by which adjacent shafts coming with engagement into each other. Additionally at least part of nozzled components allows profile of cross section, which consists of circular arcs, which correspond to maximal diametre of nozzled component, diametre of core of nozzled component and maximal distance between nozzled components. Additionally nozzled component in area of circular arc, which corresponds to core diametre of nozzled component, is implemented without moment of rotation transfer by connection shaft-bushing at abutment to drive shaft by surface or partly by surface. For moment of rotation transfer there are provided two groups from at least two connectors or tooth, herewith distance from group up to group is more, than distance from tooth up to tooth.

EFFECT: increasing of volumetric capacity of extruder at equal moment of rotation.
