Definitions

  • these known devices make it possible to produce pieces of fabric of dimensions larger than those of the device itself, provided that it proceeds in successive sections and that the sections are connected to one another in a suitable manner.
  • the object of the present invention is to provide a light and robust hand weaving device, of practical use, making it possible to produce large fabrics by the simultaneous use of several devices coupled to each other.
  • the present invention relates to a hand weaving device of the type comprising two plies of needles (1) parallel nested one inside the other and means for causing a relative and alternating displacement of the two plies in the longitudinal direction of the needles, so as to allow the deposition of a weft thread alternately on the ends of the needles of each ply, apparatus comprising a rigid frame (4) for supporting the needles and connecting means connecting the needles together of each ply, so as to allow the interlacing of the weft thread of the needles to pass over the warp threads, apparatus in which the needles have an eye to which a warp thread is attached, characterized in that the needles of the 'one of the plies are integral with the rigid frame (4) while those of the other ply are connected together by groups by drive members (12) movable back and forth relative to the frame (4) said organ drive nes (12) being connected to the frame by guide (15, 28) and stop (15a, 26) elements which extend between the needles and which are arranged
  • the apparatus comprises two plies of needles 1 which are arranged parallel to one another in the same plane, and which are intended to receive the weft thread. These needles are carried, on the one hand, towards the front by a sliding support 2, and on the other hand, at their rear end by the rear cross-member 3 of the frame of the apparatus which is generally designated by 4.
  • the frame comprises, in addition to the rear cross member 3, a front cross member 5 and two parallel beams 6.
  • the latter will preferably be of circular section and made of aluminum, their ends being molded in the front and rear cross members.
  • the frame thus takes the form of a rigid rectangular frame.
  • the crosspieces 3 and 5 are intended to rest on a table or any other flat surface.
  • the frame can also rest, for example, on the user's knees.
  • connecting elements formed, for example by lateral studs 7 and housings 8.
  • the housings are arranged so as to receive the lateral studs of another frame which would be arranged parallel to that which is shown in drawing.
  • the sliding support 2 comprises a lower cross member 9 which is fitted with tubular slides 10 engaged on the side members 6.
  • the cross member 9 has a series of parallel notches (9a) (fig. 3) with an arcuate profile. circle in which not feels the needles 1.
  • These needles are held in place by an upper cross member 11 which is removably attached to the cross member 9 by means which will be described in more detail with reference to FIG. 3.
  • the assembly 2 can be moved by hand along the side members 6 as the work progresses as will be seen below. Although it supports the needles at their anterior end, these are not rigidly fixed to the sliding support, which moves without entraining them.
  • the needles 1 are in a stretched and anodized light alliggel, of circular section. Their front end is curved upwards so as to hang the weft thread and their rear end carries an end piece 34 in the shape of an eye. The latter will for example be made of plastic.
  • Each needle has a thinned part 1a (fig. 2) limited by two flats in the vicinity of the eye 34.
  • the rear end of the frame 4, that is to say the cross member 3, is arranged so that half of the needles are fixed relative to the frame, while the other half is movable longitudinally back and forth between two predetermined extreme positions.
  • the crosspiece 3 has a series of rectangular notches 3a in which engage the flats of the needles.
  • the flats 1a For a ply of needles constituting the fixed ply, the flats 1a have a length equal to the thickness of the cross member, so that the needles are thus retained longitudinally in place.
  • the flat 1 b is much longer than the thickness of the cross-member 3.
  • a series of drive members 12a, 12b, 12c, 12d, 12e, are mounted side by side on the cross member 3.
  • the exact arrangement and mounting of the various members 12 are visible in FIGS. 2 and 3. All the members 12 being the same, only one of them is shown.
  • It mainly comprises a rectangular plate 13 provided on its upper face with a stud 14 acting as a handle.
  • the plate 13 has two parallel longitudinal slots 15 and at the front and at the rear, transverse walls 16, 17 provided with notches having the shape visible in FIG. 4.
  • each wall 16 or 17 has two semi-circular indentations 18, 19, a quarter-circular indentation 20 and three rectangular slots 21, 22, 23 disposed respectively opposite the indentation in a quarter of a circle 20 between the notches in a semi-circle 18 and 19 and between the notches 19 and 20.
  • the plate 13 immediately set back from the rear wall 17, the plate 13 has a transverse slot in which the two are engaged feet 24 and 25 of a stop member 26 which has a rear flange 27 (fig. 2).
  • the feet 24 and 25 are provided with lateral spouts (fig. 4) which block the member 26 relative to the plate 13 while allowing it to move vertically over a certain distance relative to it.
  • the slots 15 are profiled and have internal flanges 15a which extend to half the height of the thickness of the plate 13. However, these flanges are inter-ruptured at the rear end of the slot where the latter is circular in outline.
  • the length of the flat 1 b corresponds to the length of the plate 13 of the actuating members 12.
  • the needles of one and the other type being interposed, we see that the fixed needles whose flat 1 a is of short length will be engaged in the notches in a semicircle or in a quarter of a circle 18, 19 or 20 of the actuating member, while the other needles will be secured to the members d 'drive since their flat will be engaged in the slots 21, 22 or 23.
  • the drive members 12 will be placed, as shown in Figs. 2 and 3.
  • the stops 26 maintain the rear walls 17 at a certain distance from the cross-member 3, so that the screws 28 fixed in the top of the cross-member 3 are engaged by their heads above the flanges 1 5a.
  • the drive member 12 can slide from the position of FIGS. 2 and 3 backwards. It then drives the three needles of the moving sheet which are subject to it. These needles being longer than the needles of the fixed ply, their curved ends are placed behind the line of the ends of the fixed needles, while in the position shown in the drawing, they are located in front of this end line. .
  • the movable needles driven by the members 12 slide in the notches 9a of the cross member 9 of the sliding support 2 and perform a reciprocating movement controlled by the members 12.
  • the pins 32 mounted in the upper face of the lower cross member 9 are then released, which allows the elimination of the cross member 11.
  • the set of needles on which the interlacing of the weft threads is mounted can then be lifted and transferred behind the comb 33 which constitutes an auxiliary member of the device described.
  • the warp threads will be attached to the eye 34 formed at the rear end of the needles 1, and these will be pulled through the interlacing of the weft threads, which will put the warp threads in place.
  • Each needle 1 will then be successively replaced on the frame 4 after the sliding support 2 has been brought forward.
  • the upper cross member 11 of the sliding support 2 and the drive members 12 will then be replaced, which will allow the laying of the weft thread to continue.
  • the two outer needles which belong one to the fixed ply and the other to the movable ply have at their anterior end a slight offset towards the outside, in order to respond to the slight tension weft thread.
  • the needles which are at the limit between two frames should be replaced by straight needles like the normal needles.
  • the apparatus described can also be constructed in other dimensions and in other materials, for example with finer needles spaced apart, for example, by only a few millimeters.
