Definitions

  • Pneumatic tuck-in devices are known, for example, from US 4957144 and WO 01/86047 Al.
  • the pneumatic tuck-in devices are located at least partly on the side of the reed before the beat-up line or the edge of the fabric.
  • Figures 17 to 22 show a tuck-in device according to the invention in various positions during two weaving cycles .
  • a number of blowing openings 32 to 37 are formed in the direction of movement A of the tuck-in device 5; more particularly, a plurality of blowing openings 32 to 34 are formed next to one another in a row 38 above the slot 28 and a plurality of blowing openings 35 to 37 are formed next to one another in a row 39 below the slot 28.
  • these blowing openings 32 to 37 are directed principally toward the shed 1.
  • all of the blowing openings 32 to 37 can be directed in the same direction, for example in the longitudinal direction B of the sley 11. As the blowing openings 31 to 37 move together with the sley 11, the air jet from each blowing opening can cover a certain area.
  • a further main nozzle 67 and a thread holder 68 which is attached at the level of the transverse support 65 in proximity to the insertion side 16 of the shed 1.
  • the thread holders 66 and 68 can each be controlled by a valve system in order to be able to exert from the moment of the beating-up of the weft thread 19 the necessary force, for example suction force, on an end of the weft thread.
  • a cutting apparatus 83 in the for ⁇ i of v/cffc scissors Cau. be attached to the transverse support 65 in order to cut a beaten-up weft thread 19 during beating-up in proximity to the end of the main nozzle 67.
  • the shape of the slot 28 also allows the slot 28 to move continuously over the extension of the edge 15 of the fabric 3 in the direction of or toward the reed 13 and together with the reed 13. Furthermore, the slot 28 has a funnel-shaped inlet to allow the end 23 of the weft thread 19 to be taken up by the slot 28 in a simple and operationally secure manner.
  • the tuck-in device 5 can move together with the reed 13 still further away from the edge 15 of the fabric 3.
  • the cut-off part of the end 23 of the weft thread 19 can subsequently be removed in a known manner via the thread holder 66.
  • the separate fastening of a tuck-in device and a cutting apparatus allows the distance therebetween to be adjusted in a simple manner and the length of the ends to be tucked in of the weft thread thus to be adjusted. If the tuck-in device and the cutting apparatus are mounted on a single holder, the length of the end to be tucked in can, for example, be adjusted using cutting blades extending over a specific axial distance with respect to their fastening, for example axially extended cutting blades.

Abstract

La présente invention concerne un procédé permettant de replier l'extrémité (23) d'un fil de trame (19) dans la lisière (27) d'un tissu (3) au moyen d'un dispositif de rentrage pneumatique (5). La procédé consiste à faire passer l'extrémité (23) d'un fil de trame (19) inséré et rabattu et s'étendant au-delà de la lisière (27) d'un tissu (3) dans un pas subséquent (1), le dispositif de rentrage (5) étant animé d'un mouvement de va-et-vient le long de la lisière (27) du tissu (3) de manière synchronisée avec le peigne (13). Puis cette extrémité (23) du fil de trame (19) rabattu est passée dans un pas (1) tandis que le dispositif de rentrage (5) effectue un mouvement de va-et-vient le long de la lisière du tissu.
