Abstract (en)

[origin: EP1184097A2] The opposing guide walls (FW) of the guide channel (FR) narrow down steadily from entry (EO) into funnel shape and then steadily expand from before the center to the outlet opening (AO). With a channel (FR) turning 360 degrees from entry (EO) to outlet (AO) the narrow part formed by the contracting walls (FWR, FWV) accounts for 0 to 110 degrees of the 360 degrees turn so the ensuing expanding parts accounts for 250 degrees . The rear channel (FR) wall (FWR) towards the outlet (AO) rises through 360 degrees at a constant angle ( alpha ) to the outside (AU) of the support (TK) as against the leading channel wall (FWV) which remains level in the 110 degrees region only to rise at angle ( beta ) more steeply than the rise angle ( alpha ) of the rear wall (FWR).
