Definitions
- the invention relates to a lifting wire for a device for forming a Leno edge on a woven or knitted fabric, comprising two lifting strands and one mutually entrained by the lifting healds Half strand, the lifting strands in the area of one end for controlling the Half strand has at least one magnet, and to take the Half strand has a web, the distance between the web and the magnet corresponds approximately to the length of the legs of the half strand.
- a lifting cord of the type mentioned is from DE-PS 38 18 680 known.
- the device for forming a leno edge consists of two lifting healds, one on two reciprocating heald frames Loom are arranged.
- the device for forming a The leno edge also includes a half strand, which extends from the lifting strands alternately depending on the movement of the heald frames is taken away.
- the half strand has two legs, which on her upper end with the formation of an eyelet for guiding a standing thread converge.
- Such a half strand is also made of one made of metallic material.
- Each lifting wire has at least one magnet at its lower end, the controlled entrainment of the half strands by the respective lifting strands causes that the magnetic force ensures that the Half strands from the lifting strands during the respective movement is held by the lifting heald.
- This principle is - as already executed - known from DE-PS 38 18 680. The is taken Half strand through the lifting heald and one arranged in the lifting heald Bridge on which the half strand with its upper end eyelet during the Carriage movement by the respective lifting heald.
- the invention is therefore based on the object, a lifting wire of the beginning mentioned type to create an increased lifespan even at very enables high-speed weaving machines.
- the lifting wire for the magnetic deceleration of the half strand has at least one second magnet which points in the direction of the web spaced from the first magnet is arranged in the lifting heald.
- the lifting heald shows two legs, the one leg with the lifting wire has a slot, the magnets in the wall of the leg of the lifting heald forming the slot are arranged. From this it is clear that the magnets their magnetic force Apply laterally to the legs of the half strand. The magnetic force of the second upper magnet and thus the braking effect of this magnet on the half strands, must naturally with the number of strokes of the loom correlate. This means that a high number of strokes has a large magnetic force conditionally.
- the magnetic force of the second upper magnet is always like this dimensioned so that the legs of the half strand still in the area of bottom magnets, otherwise there is no control of the half strands is more possible, with the result that the leno thread is no longer with Security from one side of the half strand to the other side of the Half-strand arrives during the reciprocal movement of the lifting strands.
- the means that usually the second magnet has a lower magnetic Has force than the first lower magnet when installed.
- each wall Leg of the lifting heald opposite two brake magnets arranged, which ensures that the leg of the half strand at least by one of the two magnets to achieve braking is used.
- the frictional force is independent of the Speed.
- ferromagnetic Braking material becomes material for the legs of the half strands caused the magnetic field between the two itself opposite magnet is changed.
- the strength of the Attraction is proportional to the product of field strength and Change of the field strength and thus only of the position of the Magnets and the half strands are interdependent.
- the forces that are generated increase proportionally to Speed at which the legs of the half strands through the area of the are passed through two opposing magnets, on.
- prerequisite for braking using eddy current is that the material of the half strand is electrically conductive, and - as already executed - is passed through the magnetic field.
- Magnetization losses of hard magnetic material can also be used to achieve a braking effect be used, the braking effect with the number of Magnetization increases proportionally per path or per time.
- the Braking effect is therefore also proportional to the speed with which is the leg of the half strand in the magnetic field of the two opposite magnets moved.
- the half strand must consist of hard magnetic material, and the leg must be through a certain field formation in the field of magnets is particularly high Have number of magnetic poles to change the direction of flow, so that As many magnetic reversals occur when passing the magnets.
- the device 1 for forming a leno edge comprises two lifting healds 2,3, which can be connected to reciprocating heald frames, and take the half strands 50 mutually accordingly.
- the principle of operation is known, for example, from DE-PS 38 18 680 which is hereby expressly referred to.
- Each lifting heald 2, 3 consists essentially of two legs 10 and 20, each of these legs 10 and 20 being a hook-shaped element 11 or 21 for attachment to the heddle support rails (not shown) correspondingly alternately moving heald frames of the weaving machine having.
- the half-strand 50 shown in FIG. 4 shows two legs 51, the ends converge to form an eyelet 52, one below the eyelet roof-shaped connecting web 55 can be seen. At its free end show the legs 51 of the half strand 50 plate-shaped lugs 53.
- the leg 20 of the lifting heald 1 shows a slot 22 for various inclusion of the leg 51 of the half strand 50 (Fig. 3) trained.
- At the upper end of the leg 20 is one Guide opening 30 is provided, which is the entrance to the slot 22 of the Legs 20 represents. That means that through this guide opening 30 Leg 51 of the half strand 50 is passed.
- the guide opening 30 also has the leg 20, the web 23, on which the semi-heddle sits with its roof-shaped connecting web 55.
- Such a magnet pair 40 consists of two magnets 41, 42, which are opposite each other in the walls 25, 26 of Leg of the lifting heald 2, 3 are arranged.
- a further pair of magnets 60 consisting again from two magnets 61, 62, which correspond to the Magnet pair 40 also opposite each other in the walls 25, 26 of the leg 20 of the lifting healds 2, 3 are arranged.
- the distance of the Magnet pair 40 to the web 23 corresponds approximately to the length of the Leg 51 of the half strand 50.
- the leg 51 When the legs 51 of the half strand are moving along the slot 22 in the lifting heald 20, the leg 51 now reaches Half strands 50 first the magnet pair 60. Since the half strands as a whole is made of a magnetic material, the leg 51 with the plate-shaped lugs 53 from the magnets 61, 62 of the magnet pair 60 tightened and slowed down before the half strands with the Connecting web 55 to lie on the web 23 of the respective lifting heald 2, 3 comes. Then the plate-shaped lugs 53 arrive Leg 51 of the half strand 50 in the area of the pair of magnets 40 where these plate-shaped approaches then also by the magnet 41 or 42 are tightened, and the half strands during the take-along movement hold it by the respective lifting heald 2, 3.
