Definitions
- the present invention refers to a loom and a method of making fabrics.
- threads are used usually made from nylon or polyester, fed from two reels (so-called “big reel”) located on the two sides of the loom, as shown schematically in Fig. 1.
- big reel located on the two sides of the loom, as shown schematically in Fig. 1.
- Fig. 1 Represented in this figure are the big reels R, warp O, weft-feed system T, heddles L, fabric TE and selvages C.
- the threads of the big reels by interweaving with the weft threads in the same way as it occurs for those of the warp, form two ribbons of fabric or selvages, in which the warp threads are actually made up of the threads from the big reels.
- the very fabric that is, the one delimited by the selvages, is in the process of formation, the same selvages are cut in the direction of the warp and removed by an aspirator or "selvage puller" which convey them up to a waste-collection point.
- the cutting of the selvages implies also cutting the end portions of the weft threads by a length slightly greater than the selvages.
- the interlace of the threads from the big reels and the lengths of weft threads thus obtained is in fact inextricable, so that it results practically impossible to remove the lengths of weft threads out of said interlace in order to recycle them. All this brings about a significant lost of raw material and weighs a great deal negatively on the production costs.
- the main object of the present invention is to overcome the above drawbacks. This result has been achieved, according to the invention, by devising an operating method and providing an apparatus having the characteristics indicated in the independent claims. Further characteristics of the present invention being set forth in the dependent claims.
- the present invention allows reducing the costs for producing fabrics and recycling a good deal of material which would be otherwise lost. Moreover, a machine according to the invention is relatively simple to make and reliable even after a prolonged service life.
- a loom according to the present invention comprises an apparatus for feeding weft threads, means (not shown in the drawings) for feeding the warp threads, a reed 2 and a set of heddles 3 upstream of the reed 2, means for withdrawing the weft threads and transferring them from one side to the other of the loom across the warp, with a thread-delivering reel 4 and an opposite needle-shaped movable catching hook 5 which are disposed downstream of the reed 2, and means (not shown) for collecting the fabric as it is being formed.
- the structure and operation of apparatus 1, warp-feeding means, reed 2, heddles 3, reel 4, hook 5, and of fabric-collecting means are of a type known to those skilled in the art and, therefore, will not be described in greater detail.
- the present tool comprises two sets of additional heddles 6 disposed between the reed 2 and the first heddles 3.
- the extension of the additional heddles 6 in the direction of the weft is such that each set operates on a corresponding side band of the fabric in the course of formation.
- the loom is also advantageously provided with means for cutting end portions of weft threads projecting from the warp downstream of the reed 2, and means for the recovery of lengths of weft threads thus obtained.
- said cutting means comprise, for each side of the loom, two circular blades 7 fitted on a support 8 in correspondence of which a suction mouth 9 is provided for aspirating the lengths of threads as they are being cut and conveying them downstream up to a collection point via suitable channels.
- a clamp 10 positioned between the reed 8 and said cutting means 7, is a clamp 10, intended for retaining each weft thread hooked up by said catching hook 5 upon the return of the latter to its initial position.
- a further clamp constructed likewise, is provided in a position corresponding to the side of the weft threads-feeding apparatus 1.
- the thread-delivering reel 4 takes a weft thread from the feeder 1 and delivers it to the hook 5 (Fig. 3A) which carries the corresponding end thereof to the other side.
- the additional heddles 6 are closed (Fig. 3B).
- the first heddles 3 are closed, the weft thread is retained by the clamp 10 and the side heddles 6 open up (Fig. 3C).
- the reed 2 is made to abut and to push the weft thread, already steadily interwoven with the warp threads, towards the unit for cutting and drawing the end lengths (Fig. 3D).
- the latter are clean, that is, not interwoven nor mixed with different threads, so that they can be easily recycled, which proves to be even more advantageous when dealing with valuable or precious yarns.
- An operational method according to the invention implies, therefore, carrying out the weaving by using a set of additional heddles disposed between the main heddles and the reed of the loom, and advantageously acting on two sides of the fabric in the course of formation, while a wider central region being acted upon by the main heddles alone.
- Fig. 4 shows a possible embodiment of an automatic system for controlling'the operating members of the loom, with a programmable central unit 11 connected to the controls of the feeder 1, reed 2, first heddles 3, reel 4, hook 5, second heddles 6, blades 7 and clamp 10, according to a functional scheme known per se to those skilled in industrial automation and, accordingly, not described herein in greater details.
