Definitions

  • the invention relates to a terry weaving machine with a first device for Delivery of a basic warp thread sheet and a second device for delivery at least a pile of warp threads, with fabric threading agents and with compartment-forming elements for the Warp threads.
  • the compartment-forming elements are weft insertion means and weft attachment means assigned to the weft threads at a predetermined distance of the web line or the edge of the goods (partial stop) and then the entered Weft threads in groups on the stop edge, i.e. the edge of the goods (full or group posting).
  • group stop the pile warp thread tension lowered and the warp thread yielded so that the warp threads are too Loops are set up while the weft threads are held between the tensioned Basic warp threads slide until they are attached to the goods edge.
  • the terry weave which is only outlined in its basic features, is a well-known one Weaving technology, which is described, for example, in the book "WEBEREI Maschinen für die Tissue production "by Dipl.-Ing. J. Schneider, Springer-Verlag Berlin / Göttingen / Heidelberg 1961, pages 17, 277.
  • a typical example of a terry weaving machine is from DE-PS 2225604 known, in which the basic structure of such a terry weaving machine is illustrated.
  • the basic warp threads are released from a basic thread warp beam and redirected to the horizontal weaving plane via a spring-loaded spanning tree they are united with the pile of warp threads by one above the weaving plane arranged pile thread warp beam is lowered.
  • the pile warp threads are around their own spring-loaded tensioning boom, which is arranged above the base warp thread coulter, extends across the width of the weave and the pile warp threads from above, essentially tangential, introduces into the basic warp thread family.
  • the basic warp threads and the pile warp threads pass through warp thread monitors arranged in the weaving plane, behind which they work together Pass through shedding elements in the form of healds to pass through them Advised or reed to extend to the fabric edge, the so-called Stop edge forms.
  • the shed produced by the healds lies with the The tip of his front compartment at the stop edge and ends with the tip of his Rear compartment in the area of support rods for the basic and pile warp yarn coulters common warp stop motion.
  • the pile of warp threads runs over one Spring-loaded, arranged above the weaving plane and the basic warp thread family Dancer shaft at a small acute angle from above into the basic warp thread family a, the pile warp threads only in the area of the rear compartment between the base warp threads penetration.
  • the warp thread monitors can therefore only be arranged as described above become.
  • the terry weaving compared to the Smooth weaving is more difficult and complex.
  • the well-known terry weaving machines therefore only the function in the foreground, which ensures that the Loop formation, the warp tension control for basic and pile warp threads as well as the Warp thread monitoring for the production of terry fabrics are perfectly possible.
  • these machines which are often quite complicated, little is paid to Accessibility, for example the warp thread monitor and ease of use. Because of The increasing increase in the performance of weaving machines is becoming more and more Warp beams with a larger capacity are used, which increases the accessibility of the Warp thread monitor for its operation is further deteriorated.
  • the invention is therefore based on the object of a terry weaving machine create that with high performance and operational safety through better Easy to use and maintain.
  • the basic warp thread family and the pile warp thread family are separate from each other separate warp thread monitors assigned, which from at least one machine side, i.e. are freely accessible on the warp beam side or fabric side.
  • the Warp thread monitors for the basic warp thread coulter and the warp thread monitors for the The pile of warp threads can be arranged on two different levels, which means that Accessibility is usually further improved.
  • at least the The pile warp thread in the area of the pile warp guard in a preferably horizontal one Level. Precisely due to the arrangement of the pile and basic warp thread monitors in The warp thread break repair is very different on two different levels easy to use. Because of the between the pile warp threads and the base warp threads formed crosshairs can namely a warp thread break in the rear compartment easy to control and easy to fix by the operating personnel.
  • the pile warp thread family is the basic warp thread family crossing through in an area that passes between that of the compartment-forming elements formed back pocket of the pile warp threads and the delivery device the basic warp thread family lies.
  • the terry loom expediently has deflection means for the Pile warp threads on that of the delivery device for the pile warp yarn sheet opposite side of the base warp yarn sheet are arranged.
  • This deflecting means may at least have a deflecting rod over which the pile of warp threads is guided.

  • the deflection rod can be used to keep the frictional forces low be rotatably supported, as may also be expedient, the deflecting rod resilient to be resiliently stored and, if necessary, adjustable.
  • the arrangement can be made such that the pile warp and the Basic warp thread coulter at the crossing point, seen in the thread running direction, a blunt or enclose an acute angle with each other, the two warp thread groups can also cross at an angle of about 90 °.
  • the pile warp threads achieved a strong reciprocation of the pile warp threads in the area of the warp thread monitor is avoided.
  • the pile of warp threads is conveniently in an area in the thread running direction before the intersection with the base warp thread family lies, passed through a device for forming a pile warp reserve, the a compensation of the length of the warp threads when forming loops and / or changing the subject causes.
  • This device for forming a pile warp thread reserve can be at least one spring-loaded, partially wrapped by the pile warp threads, Have thread length compensation element that, for example, a resiliently mounted Deflection rod is or a resiliently designed and / or stored thread deflection plate having.
  • the described guiding of the warp threads allows the resulting pile warp thread length for loop formation in terry weaving with fabric control or terry weaving with store control in such a way that the pile warp tension before Group stop is lowered and the spring-loaded deflection rod or that Spring plate-like deflection plate partially absorb the pile warp thread length.
