ABSTRACT:
A processing shaft for screw machines for working materials of solid, liquid, plastic or highly viscous consistency, which processing shaft comprises a driving shaft with several sleeve-type work segments mounted thereon. Clamping means are associated with each two of adjacent end faces of said work segments for sealingly pressing said adjacent end faces against each other in axial direction, and a gas-filled O-ring received in grooves of the adjacent end faces for being compressed between said end faces. Each of the grooves has an annular zone against which said O-ring is pressed and in which any machining indentations having a peak-to-valley height of more than 2 .mu.m extend concentric to the driving shaft.
