Heating tube for heat treatment of yarns

The invention has a heating tube for heat treatment in particular of running yarns, for example synthetic threads to the object, which along at least one plane containing the threadline is divided.

In particular, threads or yarns made of synthetic materials are used in the aftertreatment, for example often subjected to a heat treatment when stretching or fixing twists or elongations For this purpose, heated plates are used in some cases, over which the yarns are drawn and of which the Heat can generally be transferred to the yarns by heat conduction. Such heating plates have the advantage the. Simplicity and the disadvantage that the heat is unevenly transferred to the yarn, that is especially on the side of the yarn that rests on the heating plate.

It is known to avoid this disadvantage in that the yarns are surrounded on all sides by the yarns, in particular tubular heating elements are guided, the heat essentially by radiation from all Sides evenly on the one in the center of the radiator

3J guided yarn transfer

oo I can easily feed the yarn into such a radiator ^ To be able to, it is already known to divide the radiator in "^ a level containing the thread run and

co to design one of the two parts to be movable away from the other » f- However, this version still has the disadvantage that the Yarn when laying in its through the radiator

leading thread run already in the HeiEzone of the stationary Part of the radiator and, as a result of the insertion compared to the later normal run, often lower Feed speed is slightly overheated and burns.

In order to avoid this technical part, the invention proposes, train both parts of the heating pipe to be movable by a common striker. In this way it is achieved that the yarn lies completely outside the heating zone of the heating tube when the heating tube is open and that both parts of the heating tube moved together when opening and closing, i.e. moved away from or towards the twine

The arrangement is advantageously made so that the two parts of the heating pipe are pivotably mounted and pivotable by means of a sole casting piece. In a In another advantageous embodiment of the invention, the two parts of the heating pipe are guided so that they can be displaced in parallel and displaceable by means of a locking piece.

According to the invention, the striker is displaceable on a guide and in its end positions by pressure members or »can be held in place by locking members ·

Another advantageous embodiment of the invention is characterized in that the locking piece by a spring located on the striker and on a collar of the guide of the striker or on a stationary Machine part is supported in one of its end positions, preferably in the position corresponding to the closed position of the heating element and by a releasable lock on its guide in its other end position, preferably in the one corresponding to the open position of the heating element Position that is tenable.

In a further embodiment of the invention it is proposed that the guidance of all strikers of a machine with

several heating pipes can be displaced in such a way that, by moving the guide, the closing parts are inserted into the Positioning of the heating elements in the appropriate position be swept up. In this way, all heating pipes can one machine can be opened or closed together

In the figures of the drawing, two embodiments of the invention are shown by way of example It is clear that the invention is still further advantageous Embodiments is to be realized.

Leaf 4

The present invention is understood by the term "Yarns" textile threads of all kinds such as endless monofilaments or multifiles made of synthetic polymers as well as yarns or threads made from natural or synthetic fibers.

The heating element 25 according to the invention consists, viewed from the inside out, of a heating tube lol, the heating elements Io3 advantageously in the form of electrical heating wires and an insulating layer Io5. These three Jackets of the heating element are divided along their longitudinal axis and from each other and from that in the axis of the jackets running yarn can be moved 9o

For this purpose, the two parts of the heating element 25 in the embodiment according to FIGS Machine frame attached hinges Io7 and Io8 pivotable. Furthermore, the parts of the heating element are by means of struts Io9 is connected to a striker 111 which can be displaced on a guide 113.

In the embodiment according to FIGS. 5 to 8, however, Bind the two parts of the heating element 25 are guided by pins 115 such that they can be displaced relative to one another. They are also articulated connected to struts 117, which can be pivoted on a fixed joint 118 and by means of pins 119 in coulisse of the striker 111 are guided.

A spring 123 attached to one on the guide 113 Disc 124, the striker presses against another disc 125 attached to the guide When moving the closing piece 111 against the effect In the spring 123, a rod 128 under the action of a spring 127 falls into a groove 13o of the guide 113 and holds the sole casting 111 in this position. At the button 129, the rod 128 can be pulled out and the locking piece can be locked 111 to be repealed. The guide 113 is also mounted in brackets 114 (FIGS. 1 and 5) so as to be longitudinally displaceable.

S. F. 5

If a new yarn is to be inserted into the heating pipe, the sole piece 111 is pushed so far to the left that until the rod 128 falls into the hat 13o and holds the striker in this position (Fig. 3 or 7) This causes the parts of the heating element 25 to separate from each other moved away and release the thread run for inserting a new yarn 9o. When the thread is inserted and runs, the rod 128 is pulled out at the button 129 and thus the locking of the striker is canceled. That Sohließstüok 111 is returned to its normal position by the spring 123 and the heating element 25 is closed in the process.

The temperature of the heating element may only affect the running yarn. If the yarn is near the treatment site comes to a standstill, for example by switching off the drive, the guide 113 is moved and thereby the heating element opened (Fig. 4 or 8). If there are several treatment sites on a masohine, each with a heating element 25 are present, are due to this displacement of the running in this case over the entire length of the machine Guide 113 all heating elements open at the same time baw. when restarting the machine by moving back the guide 113 closed again together.

The device according to the invention accordingly allows both the opening and bottom closing of individual heating elements, for example for inserting yarns, as well as the joint opening and closing of all heating elements of a machine equipped with several heating elements when stopping the masohine and the yarn
