Definitions

  • Half heald of a leno edge device with lifting healds the half heald has two legs, which at their upper end to form one Head are connectable, and one foot each at its lower end have, the foot with the at least one magnet Lifting wire works together magnetically.
  • a leno selvedge device of the type mentioned is known from DE-PS 38 18 680 well known.
  • the device for forming a The leno edge consists of two lifting healds, the two alternately moving heald frames of a loom are arranged.
  • the A device for forming a leno edge also comprises a Half strands, which from the lifting strands according to the movement of the Heald frames are taken alternately.
  • the half strand has two thighs that form at their top end forming a head converge with an eyelet to guide the upright thread.
  • Such Half strand is made of metallic material.
  • Each lifting wire has their lower end has at least one magnet that is controlled Carrying the half strand through the respective lifting strands in such a way that it is ensured by the magnetic force that the half strands of the lifting strands during the respective entraining movement by the lifting strands is held.
  • this principle is from DE-PS 38 18 680 well known.
  • the half strand is carried by the Lifting wire and here in particular by one arranged in the lifting wire Bridge on which the half strand with its end head during the Carried by the respective lifting heald.
  • the invention is therefore based on the object, a half strand of the input to create the type mentioned, which increases the lifespan of the lifting healds also possible with very fast weaving machines.
  • the foot of the Half heddle has a shape such that that on the foot of the half heddle Magnetic force acting in the stroke direction of the lifting strands is smaller than in the opposite direction, with the foot in the form of an upper end has a trailing edge, so that the semi-strands through the lifting strands is mutually magnetically braked.
  • the magnetic resistance against a Submerge the half strands against the lifting direction of the lifting strands so far is increased that it is ultimately greater than the resistance to the Lifting the foot of the half strands out of the magnetic field is required.
  • the result of this is that during this movement the half strands no longer enter the a lifting brace dips and onto the web of one lifting brace - like this is the case with the prior art - comes to rest. That is, it finds consequently there is no more wear on the web of the lifting heald, so that in principle this bridge can also be dispensed with.
  • the means that such a leno edge device comprising two Lever strands and a half strand work essentially without wear.
  • the foot of the half strands tapers downward, ie counter to the lifting direction.
  • the type of taper can be done either in cross-section or in a top view of the foot of the leg of the lifting heald.
  • the shape of the foot advantageously shows the shape of a triangle, the downward tip of which points to the center of the magnet of the lifting heald. Upwards, that is, as the upper end, the foot has the end edge.
  • the Legs cranked in the lower area to accommodate the foot is. This ensures that the foot upwards, d. H. in the stroke direction can form a free trailing edge with that already described above Consequence that the corresponding magnetic through this terminating edge Resistance to submerging the half strands against the stroke direction the leverage is increased so that it is ultimately larger than the Resistance used to lift the half strands out of the magnetic field is required.
  • leg is cranked outwards is trained. This means that the bow created by the cranking after shows outside. Such training is advantageous to the extent that in Area of the lifting heald is more space available.
  • the device 1 for forming a leno edge comprises two lifting healds 2, 3, which can be connected to reciprocating heald frames, and the 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 of essentially of two legs 10, 20, each of these legs 10, 20 a hook-shaped element 11 or 21 for attachment to the heddle support rails (not shown) of the corresponding alternately moved Has heald frames of the loom.
  • the half-heddle 50 shown in FIG. 4 shows two legs 51, 52 at its upper end to form a head 53 converge.
  • the head 53 shows an eyelet 54 for receiving the through the half-strand 50 guided thread.
  • the legs 51, 52 are on hers lower end each cranked to form a foot 70, 80 educated.
  • the offset (arrow 55, 56) is chosen such that these each form an arc outwards so that these feet 70, 80 point inwards.
  • the feet 70, 80 are designed such that taper them downwards (arrow 90), but taper them upwards Form end edge 71, 81.
  • Other embodiments of the foot can be found in FIGS. 5 to 8.
  • the leg 20 of the lifting heald 2, 3 shows a slot 22 for slidably receiving the leg 51, 52 of the half-heddle 50 (Figure 3).
  • a guide opening 30 provided the entrance to the slot 22 of the leg 20 for the Legs 51, 52 of the half heddle 50 represents. It follows that the thigh 20 in principle, forming the slot 22 from two walls 25, 26 exists, which on a long side of the slot to form the web 23rd are held together.
  • each leg 20 Magnet pair 40 Such a magnet pair 40 consists of two magnets 41, 42, which are opposite each other in the walls 25, 26 of Leg 20 of the lifting heald 2, 3 are arranged. It is now essential that the length X of the leg 51, 52 of the half strand 50 is greater than that Distance Y from the magnet pair 40 to the upper end 24 of the web 23 ( Figure 2). Because this ensures that the semi-heddle 50 with their Head 53 and here in particular with the roof-shaped connecting web 59 no longer comes to rest on the end 24.
  • a tip 76, 86 is shown, which also enables a continuous increase in material.
  • FIGS. 8a, 8b differs from that other embodiments than here the leg of the half strand from not magnetic material is formed, the tip 78, however, from magnetic material.
  • the end edge 71, 81 is thus by the Transition from non-magnetic to magnetic material.
