Definitions

  • the invention relates to a textile machine and to a corresponding textile processing method in which one or more threads under tension are processed.
  • the invention relates to textile machines, such as mattress knitting machines, in which the tensioned thread is processed with varying consumption.
  • a major cause of variations in yarn tension may be that the decrease in the yarn varies on the processing side.
  • Typical examples are here with Jacquardtechnik working textile machines, in particular round or flat knitting machines with jacquard technique.
  • the yarn consumption varies depending on the knitted jacquard pattern: the consumption drops, shoots more thread for a short time (already due to the inertia of the thread or the feeder supplying the thread feeder). This reduces the thread tension.
  • the excess thread can form a loop, which due to vibration, the knitting point in a high speed, in a sense, whip-like, can achieve (so-called whip effect).
  • whip effect the na- del the thread no longer, so that it comes to errors in the knit fabric produced knitwear. The faster the machine works, the more serious the problem.
  • Circular knitting machines preferably mattress knitting machines, have a multiplicity of knitting systems which knit the front and the back of the mattress cover fabric with their cylindrical and rib needles.
  • weft threads can be introduced and trapped in the knitted fabric at the knitting systems.
  • the front side of the mattress cover fabric is often provided with varying and / or complex patterns, which can be accomplished by means of electronic jacquard control of the cylinder needles.
  • the back side is generally simpler or not patterned so that the rib needles can each serve to support one of two knitting systems while being mechanically pre-selected or jacquard-controlled in the subsequent one.
  • the air flow can be generated in particular by an air nozzle.
  • an air nozzle can be used in the textile machine. order that the thread passes longitudinally therethrough. In this case, the thread and the air within the air nozzle are in opposite directions.
  • the air nozzle or another device generating the air flow can also be arranged such that the direction of the air flow of the thread running direction is only partially opposite in the sense that a directional component of the air flow is opposite to the thread running direction.
  • the air flow direction can also run perpendicular to the thread running direction.
  • An air flow opposite the thread causes the thread on the thread processing side in the thread running direction down the air flow device tightens. Any loops or loops of the thread resulting from the excess thread remain on the thread feed side in the thread running direction upward of the air flow device, while a uniform thread tension can be ensured for the thread processing even at high speed.
  • a corresponding air flow device with an air nozzle can also be designed in a way that allows the direction of the air flow to be reversed. This has the advantage that the thread can then be more easily inserted into the air nozzle before the textile machine is taken up or resumed thanks to the resulting suction effect.
  • the air flow device When the yarn course direction and the air flow direction are parallel or antiparallel to each other, the air flow device must be arranged so that the thread is transported through the air nozzle to thereby be exposed to the counter-current air flow. Due to the compressed air connection behind the nozzle, a further deflection of the thread between the air nozzle and the knitting point or thread guide hole to the knitting point may be necessary. To Provide the compressed air connection, necessarily common thread and air flow channel and the other Fadenum- steering is therefore required a certain distance from the knitting point.
  • the undesirable whip effects closer to the knitting point can be prevented; Namely, these are caused, in particular in jacquard-controlled knitting machines, typically by a suddenly reduced thread requirement at the knitting point and then propagate from there counter to the thread running direction.
  • the vertical air flow can be opposite to the opposite
  • a transverse air flow acting on the thread which runs at least partially perpendicular to the yarn transport direction, can therefore ensure a constant yarn tension at high processing speeds and largely independent of surface and material properties of the yarn and effectively reduce whip effects at the knitting point, without the arrangement of the machine elements along to complicate the thread course overly.
  • the emergence or propagation of whip effects can already be prevented directly at the knitting point or at least close to it.
  • the transverse air flow can be generated with an air nozzle arranged on one side of the transport path of the thread.
  • a loop receptacle for receiving the thread loop resulting from a voltage drop of the thread.
  • This loop receptacle can be formed as a slot-shaped opening in an air nozzle with respect to the transport path of the thread opposite side wall (wherein such opening may also have a different shape and may be, for example, round, oval, rectangular or square).
  • the air nozzle and the loop receptacle can be designed as separate machine components from each other; or they may both be parts of an integrally formed air flow device.
  • the air nozzle may be arranged in front of the thread guide hole leading to the textile processing parts, or at least in front of the preceding last thread guide or thread deflection element on the thread transport path. It is also conceivable to provide the air nozzle immediately in front of the textile processing station, so that the thread runs without further deflection to the processing point.
  • the air nozzle 20 mm or less in particular 15 mm or less, before the last thread guide device, as has been shown that in this way the voltage behind the air nozzle (on the processing side) can be kept particularly well at a uniform level.
  • a distance of about 10 mm has proven particularly useful.
  • the air nozzle When the direction of air flow is transverse to the direction of yarn flow, the air nozzle can be supplied with compressed air in an unproblematic manner, without resulting in valuable space in the course between the air nozzle and the processing. would be lost. It has proven particularly advantageous to provide the air nozzle or the center of the loop receptacle at a distance of less than 5% of the needle cylinder diameter to the textile processing station. A distance of about 3 cm with a needle cylinder diameter of 38 inches (96.5 cm) has proven to be particularly useful. A cross-flow nozzle consumes less compressed air while still maintaining stable and reliable thread tension.
  • the position of the air nozzle can also be designed to be displaceable along the yarn transport path, for example by being fastened to a rail and being able to be moved thereon.
  • the air nozzle can also be provided pivotably, in particular with regard to improved handling or to allow access to the thread guide or the knitting area.
  • the displacement (and / or pivoting) of the air nozzle can then be done manually or automatically controlled. Since the whip effect and the formation of loops are at least partially a vibration-related phenomenon that can vary with speed, nature and base tension of the thread as well as with the distances of the thread guide elements, can be with a position adjustable air nozzle particularly well depending on the circumstances optimal result in terms of Uniformity of thread tension obtained behind the air nozzle.
  • the exact direction of air ejection can be adjustable or controllable, from one to the thread running direction vertical direction up to one in or against the thread running direction.
  • the air nozzle when the air nozzle is positioned or pivoted out of the yarn transport path, it may effectively act as another yarn guide member by being configured to deflect the yarn within the air nozzle.
  • the air discharge of the air nozzle can be constant; but it can also be manually adjustable or controlled automatically. Both static and dynamic controls are possible here.
  • the control of the air ejection may be tuned with the control of the jacquard pattern processing. If multiple air nozzles are provided within a textile machine, the air ejection for the air nozzles can be controlled jointly or individually.
  • the air flow can also be guided by tubes with a constant or varying diameter of the thread.
  • a fluid other than air can also be blown onto the thread, for example another gas or a gas mixture in which a means for surface treatment, dyeing or impregnation of the thread is atomized.
  • the air nozzle of the present invention can be applied to various types of textile machines that process a thread under a certain tension. These are, for example knitting, knitting, weaving or sewing machines or machines for rewinding or further transporting a thread.
  • Mattress knitting machines with a high speed factor have proven to be a particularly advantageous application example.
  • Such machines have a variety of knitting systems with corresponding knitting points, each paired with Knit the cylinder and rib needles on the front and back of the mattress cover fabric.
  • On the front of the fabric often complex or varying knitting patterns are desired, so that here is a pattern-dependent interplay of cylinder and Rippnadeln used.
  • the cylinder needles are electronically selected individually by jacquard control (for E and EE selection).
  • the present invention makes it possible to maintain the knitting quality of such a mattress knitting machine even at high speed factors (above the above critical values). For this it may already be sufficient to provide the air nozzles according to the invention on every other knitting system, namely, exactly on the knitting systems, where due to the pattern-dependent interplay of cylinder and Rippnadeln the yarn consumption varies in particular. On the knitting systems, where the Rippnadeln are predominantly in the concentricity, the thread consumption is more uniform, so that the air jets are not necessarily needed here.
