Definitions

  • the invention relates to a device for tensioning warp threads on a warp threading machine, with one essentially vertically and next to a thread cutting device to separate the warp threads arranged frame for stretched Warp threads, the thread cutting device in one first edge region of the frame is arranged stationary and the frame in the direction of a in the first edge region Perpendicular to one through the stretched warp threads formed level and performed with the thread cutting device is slidably connected in the direction of a main axis and the frame is movably supported in a second edge area and for a displacement in the direction of a major axis transversely and is parallel to the plane.
  • EP 0 446 326 describes a generic device known in which the frame with the stretched warp threads suspended longitudinally in a base frame is that spans the entire warp threading machine. On The thread cutting device is the same base frame fixed attached. So the frame with the stretched Warp threads in front of the thread cutting device parallel to of the open warp thread coulter are moved, whereby the thread separating device and the individual warp threads after being pulled into a harness to pull it into the harness.
  • a disadvantage of this known device is in particular to see that both the thread cutting device, such also the frame are stored on the base frame and their position to each other about the relative position to the base frame is defined. That means that ultimately the location of the Level of the stretched warp threads as well as the position of the thread cutting device guaranteed by guides and support elements which are attached to the base frame. Such Guides and support elements are sometimes long, deformable and have play. This is the position of the thread cutting device in front of the warp threads only with restrictions. This means that the more precise the position, the stiffer and heavier trained the carriers and guides are.
  • Another device is known from EP 0 541 268. There the frame is also arranged against a stationary one Thread cutting device moved. The frame is in a first, upper edge area ajar.
  • This device includes, in addition to the limitation of usability for certain suitable for the application of the suction technology Yarn, the disadvantage that the frame is guided so that the safe retraction of the thread layer, i.e. the one to be separated Warp threads in the thread separating member or in the thread separating device not guaranteed in every case is.
  • the invention as characterized in the claims therefore solves the task of a simple and easy device of the type mentioned in which to be separated Warp threads and the thread cutting device as precisely as possible lie to each other.
  • the frame in one Bordered area mobile and for a shift is guided in one direction and in a further edge area with the thread cutting device in the same direction slidably and directly connected.
  • the Framework in at least three objections, which in the Corners of a triangle lie, guided, in two places against gravity and lateral displacement in one Direction and at least at one point only against the side Unidirectional shift. This last place is always on or in the immediate vicinity of the thread cutting element or to the thread cutting device. This also applies to another possible place to guide against lateral Shift.
  • Preferred developments of the inventive Device result from the dependent claims.
  • the advantages achieved by the invention are particular to be seen in the fact that the warp thread to be separated is always exactly in the right place in front of the thread cutting device comes to rest. This regardless of whether a base frame is locally deformed by the weight of the frame or whether the frame is warped. On the one hand, the separation of the warp thread can be carried out safely and this with a device that is not particularly heavy and stiff is to be trained.
  • Fig. 1 shows an inventive device with a Frame 1 for stretching warp threads, which are not shown here are.
  • the frame 1 consists essentially of two horizontal beams 2, 3 and two vertical supports 4, 5.
  • guide rails 6, 7 are attached for Warp threads so that they are side by side in one area or Level.
  • On the upper horizontal support 2 is also one further guide rail 8 attached to guide the Frame 1 is used.
  • a thread cutting device 13 stationary.
  • the thread cutting device 13 has a pair of rollers on the housing 14 as guide rollers 15 on, in which the rail 8 can pass.
  • a lower one second edge region 16 of the frame 1 are already called rollers 9, 10 arranged, the frame 1 mobile to store.
  • rollers 9, 10 arranged, the frame 1 mobile to store.
  • another roller 19 is also mounted in a stationary manner, on which one is only partially shown here Clamping rail 27 is supported laterally.
  • frame 1 Devices such as a brush tree 17 for clamping the Warp threads etc. attached. Such devices are on known and not significant for the present invention.
  • Fig. 2 again shows the same elements as Fig. 1, the are therefore provided with the same reference numerals. This are not mentioned again here individually. Indeed is the housing 14 of the thread cutting device 13 only partially shown. But you can see better here that the rail 8 in the pair of rollers 15 or between the rollers 15 is led. Here, however, a warp thread group 18 is shown, positioned by the guide rail 6, 7 is.
  • the frame 1 is due to the stationary pair of rollers 15 and the rail 8 only against displacements in Direction of arrow 23 out.
  • the edge area 16 is the Frame 1 by the fixed roller 19 in addition in the Direction of arrow 23 out.
  • the frame 1 will be there pressed against the roller 19 by its own weight.
  • the roles 9, 10 are preferably connected to the frame via joints 30 pivotally or tiltably connected. These joints are there preferably on the side facing the thread separating member arranged the center of gravity of the frame so that the frame 1 with the resulting, essentially horizontal component its own weight rests securely on the roller 19.
  • the frame 1 is at least three Positions A, B, C and optionally additionally at a position D stored or led. At points B and C is the frame guided along the main axis 22. At positions A and D is the Frame guided in the direction of arrow 23.
  • a guide for the Frame 1 is very close to the thread cutting device 13 and that the frame in point A and preferably also in Point D, in the immediate vicinity of the thread cutting element, across to level 20 is guided particularly precisely. This also ensures that the warp threads are exactly in the thread separating organ enter.
  • the warp thread sheet 18 has near the Thread cutting device 13 at a constant distance 25, which here e.g.
