DE1560693C3 - Method and device for the continuous production of textile composites from a nonwoven base web and at least one nonwoven web - Google Patents

Description

that at the winding point is preferably circular Has cross-section and to the right while maintaining the circumferential length in the shape of a broad, flat rectangle. In particular on the narrow sides of the winding mandrel 16 are driven Conveyor belts 20 are provided, which transport the windings 14 from left to right. At the end of the drain an extended drain tongue 22 is attached, which consists of two side rails, which lie inside the coils and keep them taut. The conveyor belts 20 can be extended so that they extend to the free end of the discharge tongue 22.

Longitudinal threads run from warp beams 24 which are arranged above and below the winding mandrel 16 26 via guide rollers 38 and are placed on the windings 14. You run across more Guide rollers to lap beams 28, which pull them off the warp beams 24, with two needling devices 42 happen. As is customary in the manufacture of needle felts, these have needle bars with a large number of needles with staggered barbs.

In the interior of the discharge tongue 22 are driven conveyor belts 66 two fleece belts 40 introduced, which run off of fleece trees 68 stored behind the tongue 22. About reversing rollers 70 they become the underside of the upper and the upper side of the lower sections of the longitudinal and cross threads of existing scrim and fed through the needling device 42 firmly with connected to these. After the lateral, vertical parts of the yarn windings 14 by two motorized driven, rotating cutting knife 72, 74, which

ίο on the flat sides of the scrim hose are provided, have been cut, you get two individual tracks 48, which are on the winding beams 28 are wound up.

In the embodiment of FIG. 3 become

ϊ · 5 next the transverse threads 14 through two above and below The needle-punching machines 64 arranged on the discharge tongue 22 are connected to fleece tapes 40. Thereafter are on the sides of the transverse threads facing away from the nonwovens, 14 tapes 54, those of tape rollers 56

run like this, put on and using sewing machines 60 sewn with rolls of sewing thread 62. After cutting open the vertical parts of the winding, what for here If a band knife 74 is used, two webs 48 result, which are wound up in the manner described above

as can be.
