Definitions
- the invention relates to a device for regulating the thread tension of the leno and upright threads guided by a leno selvedge device.
- a leno selvedge device is exemplified as a combination of lifting strands and half flash.
- two lifting strands in connection with a half flash are known to be used to produce a so-called leno edge.
- Such heddles are attached directly or indirectly to the heald frames of a weaving machine.
- the leno thread is guided between the half-strand and the lever strand, the upright thread being passed through the eyelet of the half-strand.
- the weft thread is passed through in combination with the upright thread the resulting leno edge is tied off.
- the leno edge prevents the fabric from touching this area.
- the leno or upright thread is put under tension due to the lengthening of the path when the compartment is opened.
- Both the upright thread and the leno thread are deflected several times on their way from the lifting healds to the bobbin, whereby it has been found that due to the many deflections and the resulting friction losses, the thread tension of the thread on the bobbin is compensated by the one arranged there Spring device is no longer made at all. This means that the lengthening of the thread when the compartment is opened is essentially provided by the inherent elasticity of the thread.
- the invention is therefore based on the object to provide a device for regulating the thread tension of the leno and leno threads guided through the lifting healds, with which it is ensured that when the compartment is opened, the elongation of the thread does not have to be applied by the thread itself, but rather that the thread tension in Remains essentially the same without, as already stated, the thread itself being steered.
- the object is achieved in that the upright and / or leno thread is held elastically resiliently under tension by a holder arranged directly in front of the leno selvedge device.
- the arrangement of such a holder directly in front of the leno selvedge device or the lifting strands means that the thread tension can be compensated for due to the spring action of the holder when the compartment is opened. This means that the thread itself is not elongated. Rather, it is the case that the thread path required at the compartment opening is provided in that the holder is designed to be resilient.
- the holder comprises at least one eyelet for the passage of the thread or threads, the eyelet being under the tension of a spring element.
- the holder also holds the thread down, similar to a thread hold-down device, that is, the thread is pulled downwards.
- the spring element is designed as a resilient arm, the end of the arm being designed in the shape of a hospital to generate the spring force.
- the angle between the respective arm and the thread is approximately between 70 and 110 °, preferably approximately 90 °. This has the advantage that when the thread tension and thus the deflection of the spring element changes, the height of the upright or leno thread changes minimally, and the correct function in the action as a hold-down device is not impaired.
- Figure 1 shows a schematic representation according to the previous one
- Figure 2 shows the training according to the invention.
- the bobbin holder is generally designated 1; the bobbin holder 1 has the two bobbins 2 and 3 for receiving the standing or leno thread 4, 5.
- This bobbin holder 1 also shows resilient arms 7, 8 to compensate for the different tensions of the threads 4, 5 during unwinding from the bobbins 2 , 3rd
- the threads 4, 5 are deflected twice at the points 10, 20 before they reach the thread retainer designated 30, from where the threads are guided to the lifting strands 40. Downstream of the lifting strands 40 is the reed, designated as a whole by 50.
- the hold-down device 30 has the task of ensuring that the threads 4, 5 are held under tension in the direction of the arrow 70.
- the arrow 69 is intended to indicate what the deflection of the resilient arms is when the leno or upright thread is put under tension due to the deflection of the lifting strands. It is important here that the angle between the alignment of the individual threads 4, 5 and the arms 62, 66 is approximately 90 ° in order to keep the thread tension essentially constant in each position of the arms. That is, the subject now changes from the closed subject position to the "subject open” position, then the resilient arms 62, 62 are able, due to their resilient design, to yield the required lengthening of the thread by tensioning the spring, without the thread itself being essential must absorb higher voltage.
