Definitions
- the invention relates to a take-off device with elastic bands for producing curved fabric composites on band looms.
- One conveyor belt is required for a fabric section with a clockwise curvature, for a fabric section with a counterclockwise curvature and a straight fabric section.
- the conveyor belts for the tissue sections with a curvature run over conical deflection rollers.
- the invention has for its object to eliminate the disadvantages of the prior art and to provide a trigger device in which it is not necessary to change the conveyor belts when changing the sense of curvature and the radii of curvature.
- the object is achieved in that the take-off device consists of two circumferential endless elastic belts, each of which is guided around a drive roller and around deflection rollers, the belts in addition to the drive rollers having expansion drives on both sides in the edge region, which act only on the outer edges of the belts ,
- the belts preferably have transverse teeth on the side facing the drive rollers in the edge region or continuously.
- the side of the belts facing away from the drive rollers is structured.
- the deflection rollers consist of individual roller disks which can be rotated independently of one another.
- the axes of the deflection rollers can be spring-loaded.
- Fig. 3 shows the deduction device with the same speed of the right and left expansion drives of a belt
- Fig. 4 the take-off device with different speeds of the right and left stretching drive of a belt.
- the trigger device consists of an upper band 1 and a lower band 2. Both bands are made of an elastic material, for. B. rubber. Both belts are each around a drive roller 3, 4 and guided around three deflection rollers 5, 6, 7 or 8, 9, 10. The axis of the deflection roller 5 or 8, which lies opposite the drive roller 3 or 4, is resiliently supported. The deflection rollers 5, 6, 7, 8, 9, 10 consist of individual, independently rotatable roller disks.
- the belts 1, 2 are finely toothed on the side facing the drive rollers 3, 4, which is not shown, as are the drive rollers 3, 4
- Expansion drives are also provided on the edges of the belts, which are also finely toothed.
- FIG. 1 only the left expansion drives 11, 12 are visible.
- FIG. 2 the left expansion drive 11 and the right expansion drive 13 of the upper band 1 can be seen.
- the expansion drives of the lower band are arranged
- a support roller 15 or 16 is arranged on each belt
- the belts 1, 2 are driven uniformly over their width by the drive rollers 3, 4 (cf. FIG. 3 - only the lower belt is shown).
- the drive rollers 3, 4 are set in such a way that the fabric composite located between the belts is clamped the band supports the adhesion of the fabric composite
- the area of the material clamping begins at the outlet point of the belt 1, 2 from the drive rollers 3, 4.
- the stretch drives 1 1, 12, 13 14 act on the straps, each of which only act on the outer edges. All stretch drives run at the same peripheral speed as the drive rollers Es creates a straight section of the tissue composite, the material length s, is subtracted in one time unit (FIG. 3)
- the stretch drives on one side of the belts 1, 2 are driven at a somewhat higher speed than the drive rollers.
- This process is shown schematically in FIG the lower band is shown, the left stretch drives 11, 12 run at a slightly higher speed than the drive rollers 3, 4.
- the bands on this side are stretched, with the result that the warp threads clamped on this side in the Unit of time can be subtracted by the length s a > Sj.
- the spring-loaded mounting of the deflection rollers 5, 8 ensures that the tapes do not warp when stretched.
- the sense of curvature is selected by increasing the speed of the expansion drive opposite the sense of curvature.
- the left expansion drives 11, 12 must be set to the same speed as the speed of the drive rollers 3, 4 again. Instead, the right-hand expansion drives 13, 14 are to be accelerated.
- the radius of curvature can be adjusted by changing the speed difference between expansion drives and drive rollers.
- the loom does not need to be stopped to adjust the sense of curvature and the radii of curvature.
