Abstract

A device for melt-spinning, drawing, and winding a thread group includes a spinning device having a row of spinning nozzles. The threads produced by the spinning nozzles are drawn by means of a godet device with multiple drivable godets. The device is paired with a winding device with multiple winding stations arranged in a row. The row of winding stations is arranged orthogonally to the row of spinning nozzles. The different thread spacings within the spinning device and the godet device are bridged by a thread deflecting device having a first group of thread guides and a second group of thread guides. The thread guides of the first group are arranged next to one another in a horizontal row with a spinning spacing. It is possible to obtain large deflections with a low height. The thread guides of the two groups are made of freely rotatable rollers.

First claim

The invention claimed is:

1. A device for melt-spinning, drawing, and winding a thread group, comprising:
a spinning device, which has a row of spinning nozzles,
a godet device, which has at least two drivable godets,
a winding device which has a row of winding points, wherein the row of winding points is disposed orthogonally to the row of spinning nozzles, and
a thread deflecting device disposed between the spinning device and the godet device, wherein the thread deflecting device has a first group of thread guides assigned to the spinning device and a second group of thread guides assigned to the godet device, wherein the thread guides of the first group are disposed next to one another in a horizontal row with a spinning spacing, and wherein the thread guides of the two groups of thread guides are formed by freely rotatable rollers;

wherein the rollers of the second group of thread guides are held on one or two movable supports, which can each be guided between a spreading position of the rollers and an operating position of the rollers.

2. The device as claimed in claim 1 , wherein the rollers of the second group of thread guides are disposed above one another and/or below one another with an offset.

3. The device as claimed in claim 2 , wherein the offset between the rollers of the second group of thread guides is equal to a thread spacing of the threads of the thread group on the circumference of one of the godets.

4. The device as claimed in claim 1 , wherein the rollers of the second group of thread guides are held in a central region underneath the spinning device in an inverse V-shaped row arrangement.

5. The device as claimed in claim 1 , wherein the axes of the rollers forming the thread guides of the second group and the axes of the godets are aligned orthogonally with respect to one another.

6. The device as claimed in claim 1 , wherein the spinning nozzles of the spinning device are held by two adjacently disposed spin beams and wherein the rollers of the second group of thread guides are held in the central region between the spin beams.

7. The device as claimed in claim 5 , wherein the one or two movable supports are each held by one end on a pivot axis and can be guided in an angular range as far as a horizontal.

8. The device as claimed in claim 5 , wherein the godet device and the winding device are disposed in a central region underneath the spinning device and the godet device is held at a front end of the winding device.

9. The device as claimed in claim 7 , wherein the godet device has a thread suction device, which is disposed downstream of the rollers of the second group of thread guides in the thread run.
