There are upsetting crimping devices for endless artificial threads are known in which in a bore of a carrier, a socket is used and a tube is provided in this socket, the Inside serves as a compression crimping chamber.

It is also in the case of upsetting crimping devices in which the crimped material is fed from above via feed rollers introduced into a conically widening chamber and periodically by opening a flap is led out again below, known to provide cross lines in the chamber, which into the Chamber interior open and which with a common supply line for supplying a treatment agent are connected.

The aim of the invention is to provide an upset crimping device in which the time is controlled, during which the crimped threads are subjected to the solidification conditions, and the new one and improved means for introducing a e.g. B. liquid agent in the crimping chamber as well as for Changing the size of the curling chamber.

In the upsetting crimping device for endless artificial threads or the like with one in a bore arranged bushing and a tube arranged in this bushing according to the invention is within this tube arranged a further socket which has a smaller diameter than this and which rests on a shoulder of the same in the lower part of the tube and is longitudinally displaceable at its upper part is held, wherein a ring line is formed from the socket and the tube, which with is connected to a supply pipe for a treatment agent.

According to one embodiment of the invention, a shell for another treatment liquid and one through the wall of the shell and that of the socket extending valve may be provided.

The invention achieves the particular advantage that a treatment liquid or the like can be introduced near the inlet end of the crimping chamber, so that an effective treatment of the material to be crimped is achieved. In addition, the pipe, which is held in a longitudinally displaceable manner, enables precise metering of the amount of treatment liquid to be introduced in a very simple manner. Finally, through the formation of a ring line around the tube forming the crimping chamber, hot treatment agents in the crimping chamber are evenly flushed over most of its length, with uniform radiation in the actual crimping device for endless artificial ones
Threads, thread bundles, yarns or the like.

borrowed curling chamber is guaranteed. Finally, there is a possibility of regulating the treatment agent supplied possible without practically any additional elements of the upsetting crimping device must be assigned.

In the drawing, an embodiment of the invention is shown as an example.

F i g. 1 is a vertical section through one according to the invention Upset curling device;

FIG. 2 is a partial horizontal section along line 2-2 of FIG. 1.

In FIG. 1, 10 is a crimping chamber block which is connected to a support plate 11 by screws 12 is. The block 10 is provided with a vertical bore in which a bush 13 through Press fit is attached. A tube 14 fits loosely into the socket 13 and is adjustable by means of a wedge nut 15 attached, which is screwed onto the conical slotted end 16 of the socket 13. The plate 11 carries a bearing in which a shaft 20 is mounted which carries a feed roller 21. A second feed roller 22 is mounted on a shaft 23 which is mounted in an arm 24 which, for. B. by a Bolt 25 is pivotally attached to a bearing arm 26 which is connected to the plate 11. The shaft 20 is powered by an energy source, ζ. Β. driven by a motor not shown. The shaft 23 is driven by the shaft 20 by means of meshing gears, each on the Shafts 20 and 23 are attached.

The feed rollers 21 and 22 for the crimped material 30 are pressed against one another by means of a spring 31, the ends of which are connected to a bolt 32 on the arm 24 and to a bolt 33 on the plate 11. An adjustment of the spring 31 can α by a threaded stud 33 and a nut carried 34th The yarn is guided to the contact point of the feed rollers 21 and 22 by a fixed guide 35 which is connected to the plate 11 by a screw 36.

The lower end of the tube 14 is slotted and forms a for receiving the rollers 21 and 22 Saddle; it extends below the point of contact of the rollers 21 and 22 and forms an im with them substantially closed end of a curling chamber 40.

The inner diameter 41 of the tube 14 is larger than that of the crimping chamber 40; the tube 14 extends extends to near the lower end of the block 10 and has a conical shoulder 42. A socket 43 is arranged in the tube 14 and is provided at its lower end with a conical end face 44, which rests on the conical shoulder 42 of the tube 14 or is arranged at a small distance from it can be. The socket 43 is held in the tube 14 by means of a sleeve 45 which is secured against the The end of the tube 14 is clamped by a cap nut 46. The outside diameter of the socket 43 is smaller than the inner diameter 41 of the pipe 14, so as to create a ring line 48, which extends around the sleeve 43 from its upper part to its lower end near the shoulder 42. A treatment agent can be introduced into this annular conduit 48 through a tube 49 which is attached to the pipe 14 above the block 10 and its flow rate is regulated by an adjustable valve 50. An appropriate solidifying agent, e.g. B. water vapor or hot water, a chemical solidifying agent or a colored liquid can be in inserting the curling chamber through tube 49; the threads can also be inserted by inserting them regulated amounts of oil can be greased through tube 49 as desired. In the case where no treatment agent is introduced through tube 49, sleeve 43 preferably settles against the shoulder 42 of the tube 14, so that od for the crimped yarn. The like. A continuous line is created.

The block 10 can by appropriate means, e.g. B. be heated by a heating rod 51, which is inserted into a bore 52 in the block 10 and extends parallel to the tube 14, to heat its wall. The heating rod 51 can be adjustable to the threads etc. in Bring the tube 14 to the temperature necessary for the crimping and solidification.

To add oil, paint, a solidifying agent or other treatment agent to the socket 43, a shell 60 above the block 10 is connected to this. The treatment liquid is in the bowl 60 through a pipe 61 held on a particular mirror which extends from a reservoir 62 to the mirror. The storage container 62 is connected to the plate 11 above the shell 60. The stream of the Treatment agent in the socket 43 is regulated by a valve 63 which is in an opening 64 in the wall of the socket 43 is seated, and the shaft of which extends through the wall of the shell 60. This is with a manually operated adjusting button 65 and with an appropriate one Sleeve 66 is provided to guide it in the wall of the shell 60 and the valve 63 in its position to keep.

A hollow plug 67 is inserted into the socket 43 from above and rests on the inside

ίο the crimped yarn 68 located on the bushing. The crimped yarn 68 or the like is drawn off through the bore 69 of the plug 67 by means of rollers 70, which rotate at a constant speed, with a certain ratio to the feed speed the feed rollers 21 and 22 are maintained; this relationship can be accordingly Changes in the location of the plug 67 can be adjusted to keep the plug 67 within the To keep socket 43 at a constant height.

When working, the feed rollers 21 and 20 lead the threads 30 or the like. Into the crimping chamber 40 against the pressure caused by the mass of the crimped Good in the chamber and the plug 67 is exercised. The bulk of the crimped yarn od. The like. Is along the chamber and along the socket 43 by the pressure of the game introduced is moved forward and is under tension from the top of the chamber by the peel rollers 70 pulled out. The yarn in the crimping chamber can be treated by the means, which is inserted through the tube 49 and downwards along the socket 43 through the annular space 48 flows into chamber 40 when sleeve 43 is lifted from its seat on shoulder 42. These Treatment can soften the yarn to make it easier to pucker and solidify in yarns, which also through the pipe 49 through moisture or some other solidifying agent to be introduced.

When the crimped yarn is passed up through the chamber and through the bushing 43 it is held under crimping pressure and is heated to a temperature conducive to solidification the crimping by the heated walls of the block 10 is facilitated. At the same time the yarn can be greased by oil supplied from the tray 60.

The length of the bushing 43 is chosen so that the crimp at the time when the yarn is the Reached the outlet end of the socket 43, is completely solidified.

If it is not necessary to inject liquid into the socket 43, the shell 60 can be omitted will. Furthermore, the bushing 43 can have a different length or a different length Diameter can be replaced according to the type of material to be crimped and selected in such a way that that the most effective curling condition is obtained.
