Definitions

  • the present invention relates to a method and a device for manufacturing lace bands on a multi-bar loom, and in particular on a Raschel loom. It also relates to the strips of lace obtained by this process.
  • the invention relates more particularly, although not exclusively, the manufacture of elastic lace bands intended to equip the upper edge of a woman's stocking, in order to keep it in place.
  • the object of the present invention is to remedy these various drawbacks by proposing a method and a device for manufacturing lace bands which makes it possible to weave a monofilament yarn over the entire width of each of the lace bands produced over the width of the needle bed. loom and this while maintaining its normal operating speed, which leads to an excellent yield for manufacturing lace bands having the required transverse rigidity.
  • the method according to the invention has the advantage of allowing a wide screening of each strip of lace manufactured over the entire useful width of the loom, allowing a maximum displacement on 140 needles instead of the 8 needles authorized with known systems using link chains.
  • the method according to the invention can be carried out using the device developed by the Applicant, this device being characterized essentially in that it is adaptable to a multi-bar loom of the conventional type with a view to replacing the usual link chain with a means of actuating the bars authorizing the production of the lace strips while maintaining the normal operating speed of the loom.
  • the device according to the invention comprises for this purpose a combination of means making it possible to transform the regular circular movement of one of the motor shafts of the loom into a horizontal reciprocating movement whose amplitude can be adjusted according to the result. research.
  • the device according to the invention thus offers the advantage of allowing the use of a multi-bar loom comprising as many drawing bars as desired, for example 50 or even 78 bars, by allowing the passage of the frame guide between the needles, and this at the normal operating speed of the loom.
  • the device according to the invention makes it possible to fix with great precision the extreme positions of the weft guide, which is necessary to allow it to pass between the needles at this rate.
  • the device according to the invention comprises a sheave 2 driven in rotation by a motor shaft 1 of the loom, a belt 3 transmitting the rotation to a second sheave 2 ′ crossed by a shaft 4 held by a bearing 5, and rotating a disc 6.
  • the disc 6 in turn drives in rotation an eccentric shaft 7 passing through the lower end of a connecting rod 8, said end comprising a horizontal housing allowing the shaft 7 to carry out a displacement in apparent translation relative to the connecting rod 8 during the rotation of the disc 6, so that the connecting rod 8 performs during this rotation of the displacements in alternative vertical translation.
  • the connecting rod 8 is secured at its upper end to a bar 9 secured by its lower face to two rods 10 positioned on either side of the connecting rod 8 and guided in translation by ball bushings 11 without play.
  • a strip 12 provided with a longitudinal light 13 inside which can be moved and fixed a bolt 14 secured to a rod 15 secured to its other end of a bolt 16 capable of being moved and fixed inside a longitudinal slot 17 formed in a strip 18 secured at one of its ends to an axis 19 around which it can be moved in rotation and fixed at a determined position, as well as a third strip 20 provided with a longitudinal light 21 inside which can be moved and fixed a bolt 22 secured to a rod 23 which actuates the displacement in translation of the screening bar 24 and the guides 25 attached to it.
  • the lace bands obtained according to the method and using the device according to the invention can be elastic lace bands produced by means of threads of any kind, in particular cotton or polyamide, associated with threads of elastane or elastodiene: in this case they are suitable for producing elastic bracelets intended for holding the stockings, because of their good transverse rigidity which avoids the rolling phenomenon when worn.
  • the elastic lace can be provided on its rear face with at least one strip of adhesive silicone.
  • the elastic lace bands according to the invention can also find an application in the production of belts or suspenders for underwear.
  • non-elastic lace bands according to the invention can be used in all sectors of the clothing industry where it is advantageous to use a lace having good transverse rigidity.
  • the lace bands according to the invention can be in the most diverse forms of patterns, colors, etc., and in particular have contrast effects between the background and the lace proper, these effects being obtainable by inserting therein other types of yarn than monofilaments.
