Definitions

  • the invention relates to a device for forming a fabric edge provided with a binding, in particular in the case of defenseless weaving machines, consisting of two mutually moving heald frames, one of which has a heald frame as a Guide frame trained needle holder and on the other heald frame a guide guided in the rails of the guide frame is provided, and that a perforated disk with holes for guiding the leno threads is rotatably arranged in the guide.
  • a device for forming a leno selvedge which consists of two heald frames which move in opposite directions, a guide frame for the needle holder of the upright threads being arranged on one heald frame and a thread guide device for the leno threads guided by the guide frame being arranged on the other heald frame.
  • the thread guide device consists of a perforated disc movable between two stops with at least two holes for guiding the threads, with racks being arranged between the stops for generating the rotary movement of the perforated disc.
  • the toothed racks arranged on the thread guide device are also entrained, which are held on the guide frame by magnets and thus set the perforated disk in rotation.
  • the thread slide In the needle-free space, therefore, the thread slide must be rotated, as a result of which the leno threads should jump over from one side of one needle to the other side of the opposite needle.
  • the distance between the two needle ends that is to say the needle-free space, must be chosen to be sufficiently large in the known device, since if the distance between the needle ends is too small and the working speeds are high, there is not enough time for the displacement or change the threads are present unless the needle spacing is increased.
  • Increasing the needle spacing causes a so-called dirty compartment to be formed; unclean because the upright threads in the eyelets of the needles, which should ideally lie in one plane in the theoretical ideal, are at a distance from each other in the vertical direction.
  • the compartment In order to ensure the correct insertion of the weft thread in the compartment, the compartment must be made larger. This in turn means that the lifting movements of the heald frames also increase, with the result that the time required also increases, so that the overall weaving speed decreases.
  • the invention is therefore based on the object of providing a device in which the change of the leno threads between the needles is ensured even at high working speeds with a minimal needle spacing.
  • a control element is movably mounted on the link in the working direction relative to the link, that the control element is connected to the perforated disk, and that the link is guided in the guide frame in a braked manner; the control element has stops for limiting its relative movement.
  • the braking of the movement of the link in the frame rails is brought about by several, for example, four magnets arranged in the region of the frame rail.
  • This embodiment ensures that the leno threads, even with a minimal distance from the needle ends to one another, change over from one side of the one needle to the other side of the opposite needle, since the perforated disk each time the direction changes in the link at the upper or lower end of the frame is twisted, the leno threads thus receive a pretension, and this ensures in any case that the leno threads can make the change when the needle-free space is reached.
  • control element is a frame provided with stops, preferably a C-shaped frame, the legs of which adjoin the central part form the stops.
  • the maximum distance from the inner edge of the leg of the C-shaped frame to the adjacent edge of the backdrop corresponds to the length of the circular arc by which the perforated disc is rotated. To achieve sufficient pre-tensioning of the leno threads, twisting the perforated disc by an angle of 60 degrees is sufficient.
  • the embodiment of this device is made so that the link has a groove in the longitudinal direction for guiding the central part of the C-shaped frame, that the perforated disc has a groove on its end face which extends between two adjacent bores that in the A hole is arranged in the middle of the groove-forming cheeks of the perforated disk, so that the central part of the C-shaped frame also has a hole, so that the perforated disk is positively connected to the central part of the C-shaped frame by a pin, so that the central part connects to both Sides of the bore has recesses, so that the perforated disc is rotatable in the backdrop.
  • the bore located in the central part of the C-shaped frame is an elongated hole.
  • the needles are arranged on the guide frame so that the axis of the eyelets of the respective needle runs in the direction of the thread. This ensures that, in contrast to the known design of the needles, in which the eyelets are arranged laterally, the upright threads can on the one hand be threaded in more easily, and on the other hand the wear of the eyelets by the threads is considerably reduced, since a deflection of the sides of the stand rails guided to the needles are eliminated.
  • the device for forming a fabric edge provided with a binding consists of one heald frame 1 and the other heald frame 2 (FIG. 1).
  • Each heald frame has two spaced heddle support rails 3 or 3a and 4 or 4a.
  • the two heald frames are arranged to move in opposite directions.
  • the guide frame On the heald frame 2, i.e. means on the heddle support rail 3 or 3a (not shown), the guide frame, designated as a whole by 5, is fastened, for example with the aid of clamping pieces 6 and 6a (not shown).
  • This guide frame 5 consists in detail of the two frame rails 5a, 5b designed as U-rails, the two frame rails being arranged opposite one another in such a way that a guide groove 7 for guiding the link 9 is thereby formed.
  • the needles in the guide frame are designated 7a, 7b, 7c and 7d; they have the eyelets 8a, 8b, 8c and 8d through which the upright or warp threads 16a - 16d are drawn.
  • the axes of the eyelets of the needles run according to the running direction of the upright or Warp threads.
  • the link 9 is arranged to be vertically movable.
  • the link 9 has the magnets 11, 12 on its edge in the region of the frame rail 5a.
  • a perforated disk 10 is rotatably arranged, which itself is provided with a groove 10a running on the end face is.
  • a C-shaped frame 15, which represents the control element, with the central part 15a and with legs 15b, 15c adjoining the central part is arranged movably on the link in relation to the latter.
  • the central part 15a which has a bore 16 designed as an elongated hole, projects into the groove 9a of the link, as well as into the end groove 10a of the perforated disk 10 rotatably arranged in the link 9.
  • the rotatability of the perforated disk 10 by the vertical movement of the C-shaped frame is made possible by the fact that recesses 19, 20 (FIG. 3) are provided in the central part 15a on both sides of the bore 16, into which the groove ends of the perforated disk 10 are rotated each come in.
  • cutouts can thus also serve as a stop for limiting the rotation of the perforated disk 10.
  • the frame is connected to the perforated disc by a pin 17 which projects through the bore 10 into the bore 16 of the leg 15a.
  • the length of the circular arc by which the perforated disk can be rotated corresponds to the maximum distance X from the inner edge of the leg 15c of the C-shaped frame to the adjacent horizontal edge of the link 9.
  • the C-shaped frame 15 itself is in this case via traction means 18, 18a connected to the heald frame 2.
  • the device works as follows: When the heald frames 1 and 2 and thus the heddle support rails 3, 3a and 4, 4a move in the opposite direction, the link 9 with the C-shaped frame 15 is moved up and down in the frame 5.
  • the link 9 is located on the leg 15b of the frame 15 serving as a stop (FIG. 2).
  • the thread guide device is accordingly located at the lower end of the guide frame 5.
  • the traction means 18 pulls the C-shaped frame 15 in the upward direction (arrow A Fig. 2); there is then first a relative movement of the C-shaped frame 15 to the link 9, whereby the perforated disc 10 is rotated.
  • the relative movement of the frame to the backdrop is caused by the fact that the frictional force resulting from the movement of the frame in the backdrop and the rotation of the perforated disk in the backdrop is less than the force exerted by the frame rails on the backdrop.
  • This force is composed of the force generated by friction between the frame rails and the link and the magnetic force which is generated by the two magnets 11 and 12 arranged in the area of the frame rails.
  • the backdrop 9 therefore follows the movement of the frame 15 with a delay.
  • the length of the circular arc by which the perforated disk is rotated here corresponds to the inner distance between the two legs 15b, 15c of the frame 15 minus the length of the backdrop.
  • the leno threads 21 passed through the four openings 10b - 10e of the perforated disk 10 experience a horizontal movement due to the rotation of the perforated disk, as a result of which the leno threads are tensioned.
  • the thread guide device moves further upwards, the leno threads get into the space between the needle ends, i.e. In the area between the two pairs of needles 7a, 7b on one side and 7c, 7d on the other side, the leno threads - due to the tension in the horizontal direction - will certainly reach the other side of the opposite needle, which results has that the leno threads can then each take the position required for proper binding.
  • the upright threads drawn through the eyelets 8a to 8d always make exactly one vertical movement. The binding comes about through the horizontal movement of the leno threads and the vertical movement of the upright threads.
  • a closed frame can also be used instead of the C-shaped frame, the vertical legs of such a frame being guided in corresponding grooves in the backdrop. To be able to use the closed frame in the setting, it must then be divided.
