Abstract
A filament-feeding apparatus for a wet freshly dyed yarn has a feed wheel centered on and rotatable about an axis and having a pair of side parts having generally circular peripheries lying in parallel spaced-apart planes perpendicular to this axis, and a plurality of angularly spaced center parts axially bridging the side parts and having outer edges axially aligned with the peripheries. The wheel is open and free of structure in zones radially inward of the peripheries and radially outward of secants extending between the outer edges. A flexible endless belt having a width equal at least to the axial spacing between the peripheries is held by a plurality of pulleys in a circular arc radially against these peripheries so that the belt forms upstream and downstream nips at the ends of the circular arc. A filament is fed under tension tangentially of the wheel to the upstream nip between the side parts of the wheel and is withdrawn under tension and tangentially of the wheel from the downstream nip between the side parts. The filament is thus stretched over the outer edges into a succession of straight-line secants along the engagement arc and only engages the belt at the outer edges along this arc.
