Definitions

  • the present invention relates to devices for forming the crowd of a weaving loom comprising a plurality of assemblies intended to form the crowd of the weaving loom.
  • European patent 0214075 discloses a device of the type in question, the assemblies of which each comprise two hooks connected by a funicular element, an electromagnet and retaining hooks located between two separating partitions connected to one another by view of making an autonomous assembly or module which is perfectly illustrated and described in the aforementioned European document.
  • pole pieces of the electromagnets placed between two separating partitions are not isolated from the ambient atmosphere.
  • a weaving workshop contains in suspension fatty dust made up on the one hand of waste or fluff coming from the weaving threads and on the other hand fine particles of oil and fat suspended in the 'air. This greasy dust tends to settle on the pole piece of the electromagnets which can cause malfunctions of the retaining hooks resulting in weaving defects.
  • the improvements which are the subject of the present invention aim to remedy this drawback and to place each electromagnet in a casing which is substantially airtight.
  • the device according to the invention is characterized in that, at the level of each electromagnet, each of the faces of the separating partitions has a border so that after assembly of two adjacent separating partitions, their borders facing each other. -screw come into abutment against each other to form a casing containing the electromagnet.
  • FIG. 1 There is shown on an enlarged scale in FIG. 1 one of the separating partitions 1 of a crowd formation device established in accordance with European patent 0214075, but comprising the improvements according to the invention.
  • an electromagnet 2 comprising two pole pieces 2 a , 2 b made in the form of a transverse branch, as well as two tilting retaining hooks 3, 4 which pivot about an axis 5 , 6 produced in the form of a plastic tenon secured to the partition 1.
  • the hooks 3 and 4 are provided for retaining or leaving free the movable hooks 7, 8 connected by a cord 9 and which are moved back and forth - comes by two knives not shown.
  • each separating partition 1 which supports the electromagnet 2 is provided with an edge 10 comprising two elements 10 ′, 10 ′′ extending on either side of the partition and perpendicular to said faces (fig. 2).
  • edge 10 comprising two elements 10 ′, 10 ′′ extending on either side of the partition and perpendicular to said faces (fig. 2).
  • fig. 2 there are clearly two studs 5, 6 constituting the axes of articulation of the hooks 3 and 4 as well as pins 11, 12 engaging in corresponding perforations formed in the body of the electromagnet 2 for its attachment between two adjacent dividing walls 1.
  • the edge 10 is integral with the lateral edges of the separating partition 1, then of the terminal edge of the latter, however leaving a passage 13 in the middle of the latter.
  • the edge 10 affects the shape below the electromagnet of a rounded V whose branches are interrupted to constitute two spaces 14, 15.
  • FIG. 4 a substantially sealed casing which is constituted by the elements 10 ′, 10 ′′ of two adjacent dividing partitions, since the free edges of these elements come into intimate contact.
  • the easiest embodiment consists in providing equal the height of the two elements 10 ′, 10 ′′ of the border 10, this height being equal to half the distance separating the faces opposite two partitions. adjacent 1.
