Abstract
A method and an apparatus for strengthening a textile web (8), especially a felt web, by needling parallel yarns (11) in the longitudinal direction are described. In order to provide an advantageous structure of the textile web (8) it is proposed that the yarns (11) are needled onto the textile web (8) at a lateral distance from one another and with a needling limited to the yarn zones.
Description
- The invention relates to a method for strengthening a textile web, especially a felt web, by needling parallel yarns in the longitudinal direction.
- In order to strengthen nonwoven fabric it is known to needle said nonwoven webs with a reinforcing fabric. This is connected to a condensing of the nonwoven caused by the needling, which occurs over the entire surface of the nonwoven because the nonwoven needs to be connected with the reinforcing fabric all over. An additional factor is that substantially only nonwovens can be strengthened which can provide respective fibers for needling with the reinforcing fabric.
- In order to obtain a surface covering for wallpaper for example it is known (U.S. Pat. No. 3,783,479 A) to needle cut yarn sections in an entangled position onto a backing. Yarns positioned parallel adjacent to one another could also be needled onto a backing material (U.S. Pat. No. 4,595,438 A). There is a needling over the entire surface of the backing as in the needling of yarn sections, which thus consequently leads to a consistent strengthening of the backing.
- The invention is thus based on the object of providing a method for strengthening a textile web, and especially a felt web, of the kind mentioned above in such a way that a planar condensing of the textile web to be strengthened is effectively prevented.
- The invention achieves the object in such a way that the yarns are needled onto the textile web at a lateral distance from one another and a needling limited to the yarn zones.
- By needling the yarns at a mutual distance from one another and as a result of limiting the needling zone to the yarns, the textile web can be strengthened substantially in the longitudinal direction without having to accept any consistent strengthening of the textile web over its width. The properties of the textile web are therefore maintained between the yarns irrespective of the needling of the yarns, which is relevant for a number of applications of said textile webs. The yarns which are needled onto the textile web at a lateral distance from one another and usually provide sufficient fiber material in order to ensure an effective anchoring of the yarns with the textile web to be strengthened also form a surface structure which cannot be easily achieved and represents advantageous preconditions for certain applications, e.g. in the use of such textile webs with individually needled yarns for filters.
- In order to perform the needling of yarns onto the textile web it is possible to assume a conventional needling device with a drivable needle board reciprocating in the direction of the needle penetration and a stitch base opposite of the needle board which forms a guide surface for the textile web which can be drawn off in the direction of passage of the textile web. It is merely necessary to ensure a sufficient guidance of the yarns to be needled with the textile web, so that the needles disposed in respective rows cannot miss the yarns. For this purpose the stitch base can be provided in the guide surface for the textile web with parallel guide grooves for the yarns which are aligned in the direction of passage of the textile web, so that the needles of the needle board penetrate the guide grooves and draw fibers from the textile web and introduce the same into the yarn. If fibers of the yarns are to be drawn into the textile web, the yarns must be guided on the side of the textile web facing the needle board, which entails a more complex construction.
- The method in accordance with the invention is explained in closer detail by reference to the enclosed drawings, wherein:
- FIG. 1 shows an apparatus in accordance with the invention for strengthening a textile web in a simplified side view, and
- FIG. 2 shows a sectional view along line II-II of FIG. 1 on an enlarged scale.
- The apparatus according to the shown embodiment is provided with a
needling device 1 consisting of astitch base 2, astripper 3 and aneedle board 4 which is inserted in aneedle beam 5. Theneedle beam 5 is driven in a reciprocating manner by way of an eccentric drive in the direction of penetration of theneedles 6. In contrast to conventional needle boards, theneedles 6 of theneedle board 4 are disposed in parallel rows aligned in the direction ofpassage 7 of the textile web, which rows extend with a substantial lateral distance from one another. - The
textile web 8 to be strengthened is drawn off from asupply roll 9 and supplied simultaneously withyarns 11 drawn off fromsupply coils 10 to the pair ofinput rollers 12 of theneedling device 1 whosestitch base 2 forms a guide surface for thetextile web 8.Guide grooves 13 foryarns 11 are provided in the guide surface. Since the rows of needles extend along theguide grooves 13, thetextile web 8 which covers theguide grooves 13 with theyarns 11 is needled withyarns 11, with theneedles 6 which penetrate thetextile web 8 from above drawing fibers from thetextile web 8 and needling them intoyarns 11. Thetextile web 8 thus strengthened with theyarns 11 needled onto the lower side can then be drawn off by way of a pair of draw-offrollers 14 from theneedling device 1. - If it is not intended to needle fibers from the
textile web 8 into theyarns 11, which requires a textile web with a respective fiber structure, but instead fibers from theyarns 11 to thetextile web 8, it is necessary that theyarns 11 oftextile web 8 are supplied on the side opposite of thestitch base 2. The guidance ofsuch yarns 11 facing thestripper 3 requires special measures. For this purpose finger-like spacer elements for theyarns 11 can be provided which reach into the needle zones, whichyarns 11 are prevented from a lateral migration during the needling between said spacer elements which extend in the longitudinal direction through the guiding gap betweenstitch base 2 andstripper 3.
Claims (2)
1. A method for strengthening a textile web, especially a felt web, by needling parallel yarns in the longitudinal direction, wherein the yarns are needled onto the textile web at a lateral distance from one another and with a needling limited to the yarn zones.
2. An apparatus for performing the method as claimed in claim 1 with a drivable needle board equipped with needles and reciprocating in the direction of the needle penetration and with a stitch base opposite of the needle board which forms a guide surface for the textile web which can be drawn off in the direction of passage of the textile web, wherein the stitch base (2) is provided in the guide surface for the textile web (8) with parallel guide grooves (13) for the yarns (11) to be needled, which grooves are aligned in the direction of passage (7) of the textile web (8) and that the needles (6) of the needle board (4) penetrate the guide grooves (13).
