ABSTRACT OF THE DISCLOSURE A spiral-line press comprising: a support housing, a circularly driven shaft in said housing an axial bearing in said housing supporting said shaft, means provided so that said housing for the axial bearing is simplified and the space requirements can be reduced including; said shaft defining first and second material conveying portions; a first spiral conveyor on said shaft at said first material conveying portion; a second spiral conveyor on said shaft at said second material conveying portion; said first and second spirals are opposingly oriented on said shaft for conveying material from opposite ends of said shaft along respectively corresponding portions; said first and second spiral conveyors having respective length to diameter ratios of not more than 14:1; said first and second spiral conveyors defining corresponding metering zones where conveyed material is output from said press, wherein said metering zones have a phase depth of not more than 1/25 of said corresponding spiral diameter; and means connected to said shaft for driving said spirals along with said shaft at a peripheral speed of at least 0.3 m/sec. The spiral geometry and arrangement of the several parts reduces machine bulk and permits cost reduction.
