Definitions

  • the invention relates to a lathe device for weaving machines, in particular for double rapier weaving machines for double velvet or carpets, in order to obtain corrugated edges.
  • Twisting devices are used in fabrics to position part of the warp threads, the so-called leno threads, once on the right and once on the left of the standing threads. As a result, the leno threads are twisted or wound around the standing threads.
  • DE-GM 80 05 822 describes a solution in which standing threads are positioned by needles on the one hand, and leno threads are positioned on the other by combined movement of levers provided with eyes and a guide plate provided with oblique slots that form the leno threads.
  • This lathe device requires three shed forming elements with the associated weaving frames, namely a weaving frame with movement 1/1 for the needle bar (standing thread grid), a weaving frame with movement 1/1 for the linkage of the thread eyes and a weaving frame with movement -2/2 for the leno thread positioning device.
  • the object of the invention is to realize a lathe device in which the drive is independent of the dobby, which does not require additional looms, and in which the angle-synchronous adjustment with respect to the main shaft is possible.
  • the lathe device for a weaving machine according to the invention is characterized by four-bar parallelograms with vertically standing front sides, to each of which the needles, the thread eye holders or the thread positioning eyes are fastened, while the rear side carries the joints around which the other bars of the parallelograms extend. and move so that the needles as well as the thread eye holders and the positioning eyes make a vertical movement and only describe a very small arc.
  • the linkage forming the parallelograms can be built modularly next to one another, the joints being connected to the frame and adjustable in width.
  • the warp threads are in standing threads 1 and 2 ... and in leno threads 3, 4, 5, 6 ... divided.
  • the lathe device consists of various parallelograms formed by rods.
  • the rod parallelogram of the standing threads 1 and 2 carries a needle holder 8 and a needle holder 9 at both ends of its vertical front side rod 7, wherein the upper needles 10 and the lower needles 11 are vertically adjustable.
  • the needle holders 8 and 9 are provided with a positioning device 12 and 13 ..., through which the corresponding standing threads 1, ... and 2, ... are guided, in order to then along the needles 10 and 11 and the needle tubes 14 and 15th to be directed to the weaving reed (not shown) of the weaving machine.
  • the vertical front side rod 7 of the parallelogram assigned to the standing threads is provided with joints 16 and 17 and their axes 18 and 19.
  • the rods 20 and 21 of the corresponding parallelogram can rotate back and forth about these axes 18 and 19.
  • the rear vertical side is formed by a rod 22 having an upper axis 23 and a lower axis 24 about which the corresponding upper associated rod 20 and the corresponding lower adjacent rod 21 can rotate back and forth. This has the consequence that the front side bar 7 of the standing threads can be moved up and down, whereby the needles can be held in a vertical position.
  • the leno threads 3, 4, ... and 5, 6, ... continue through the associated slots 34, ... and 35, ..., the holders 36 and 37 attached to the outer ends of the vertical rod 38 are.
  • This rod 38 is the front of the parallelogram associated with the slot holders 36 and 37, which further consists of the rods 38 and 39 and the vertical rod 22 serving as the rear.
  • the parallelogram linkages are arranged modularly next to each other on hinges connected to the frame and the width can be adjusted to the fabric width to be woven.
  • the position of the needles, slits and eyes can be adjusted with the help of set screws on the vertical pull rods.
  • the lower parallelogram rods 21, 33 and 38 each have an extension piece 40, which carries a joint 41, ... at its end and is connected to a pressure wheel 44, ... by levers 42 and 43, ..., respectively that by means of cams 45 when the cam shaft 46 rotates and by the tension springs 47 an up and down movement of the vertical front bars, the corresponding needle parallelogram, the slot holder parallelogram and the positioning eye parallelo gramms is caused.
  • the angularly synchronous setting is achieved by rotating the cam disks 45 on the cam disk shaft 46.
  • This shaft rotates 1/4 in relation to the main shaft, so that the needles 10 and 11, ... a movement of 1/1, the slots 34, ... 35, ... of 1/1 in Push-pull and the thread positioning eyes 25, ... and 26, ... perform a movement of 2/2.
