Abstract
Spinning apparatus for the production of monofilament yarn includes a spinning tool having a flow channel in the form of a flattened U for providing polymer melt to a group of nozzles, the flow channel having a cross-sectional area which becomes larger, at least in an upper part thereof, in a direction of polymer melt flow therethrough.
Claims16
Spinning apparatus for the production of monofilament yarn comprising:
- a spinning tool having means defining a channel section for receiving polymer melt and
- flow channel means, interconnected between said channel section and a group of nozzles, for widening the flow of polymer melt, said flow channel means having, at least in an upper part thereof, increased cross-sectional area in the direction of polymer flow from the channel section toward the group of nozzles.
Spinning apparatus for the production of monofilament yarn comprising:
- a spinning tool having channel portion means, in fluid communication with a group of nozzles and defining a channel section interconnected with a flow channel, for receiving a polymer melt and for widening the flow of polymer melt, said flow channel having, at least in an upper part thereof, increased cross-sectional area in the direction of polymer flow toward the group of nozzles;
- clamping means for holding the group of nozzles in fluid communication with said channel portion means;
- and
- carrier means for supporting said clamping means, said carrier means being attached to a vertically displaceable mount, said mount being disposed for movement along a spatially fixed and horizontal rail.
