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.
