Definitions

• the invention relates to a texturing machine for crimping threads according to the preamble of claim 1.
• Such textile machines are used to curl and stretch a smooth thread in a texturing process.
• the texturing machine has, in one of several processing stations, several process units and a winding device, which are arranged in a machine frame combined to form a thread run.
• the process units such as delivery plants, heating devices, kuM Huber, texturing units, tangling devices and
• Preparation devices are often arranged in the machine frame over two floors.
• the known texturing machines therefore require special auxiliary devices in order to put on the thread in the process units at the beginning of a process up to the winding.
• the thread is passed through a guide tube until just before the winding device and blown out at the end of the guide tube by a blowing opening.
• a baffle plate is arranged in the blowing direction at a distance from the blowing opening, which causes the thread to be deflected toward the winding device.
• the thread is then taken over by a suction device in the winding device.
• the known devices generally have the disadvantage that the thread undergoes a directional deflection only when the blowing action is very strong, or that the loose thread can only be picked up by a very high suction action.
• the thread sticks to the baffle plate due to the preparation residues adhering to the thread from the pretreatment. It is therefore an object of the invention to further develop a texturing machine of the type mentioned at the outset in such a way that the thread can be guided and put on automatically in the winding device with great certainty and in a simple manner before the start of the process.
• the invention is characterized in that the thread is guided without transferring to the winding device for transfer.
• the blowing opening of the guide tube and the receiving opening of the suction device are arranged opposite one another.
• the guide tube is designed to be adjustable in such a way that the blowing opening can be held in several positions relative to the opening for transferring and applying the thread.
• the functions "transfer thread” and “apply thread” can thus advantageously be carried out from different positions.
• care must be taken that the loose end of the thread can be securely picked up by the opening of the suction device.
• the thread can be easily put into the winding device without additional thread feeding devices immediately after transfer to the suction device.
• the threading and the application of the thread in the winding device can thus be made possible in a very short time, so that for example, very short process interruptions can be realized after a thread break.
• the guide tube In order on the one hand to be able to bridge a long distance between the blow opening and the receiving opening and on the other hand to prevent the thread from sticking to machine parts, it is provided according to an advantageous development of the invention to adjust the guide tube with the blow opening between two positions.
• a transfer position of the blowing opening the thread is blown out for transfer in the direction of the opening.
• This position is advantageously chosen such that the best possible trajectory for the thread is given.
• the guide tube After the thread has been taken over by the intake opening of the suction device and is guided between the blowing opening and the intake opening, the guide tube can be moved into the application position. In this position, the thread is advantageously fed into the reel for application.
• the positions are preferably arranged in a plane that is oriented vertically, horizontally or as desired.
• an end region of the guide tube with the blow opening be designed telescopically or elastically. Pneumatic delivery within the guide tube is thus unaffected by the adjustability at the end of the guide tube for positioning the blowing opening.
• the movement is preferably carried out by a controllable actuator, which is assigned in the end region of the guide tube.
• the blowing opening of the guide tube is arranged on an inlet side of the winding device in front of a winding point and the receiving opening of the suction device is arranged on an outlet side of the winding device behind the winding point.
• the thread is advantageously passed directly through the Winding point led.
• the thread can be taken over, for example, by a catching device and wound onto a sleeve.
• the thread is guided from the transfer position into the contact position into a traversing plane by the movement of the guide tube.
• a thread guide is provided for traversing the thread during winding onto a bobbin, which thus automatically takes over the thread held in the traversing plane and leads to application and catching.
• the method according to the invention is characterized in that the thread can be guided with high security and reproducibly in the winding direction and can be put on in a short time.
