Definitions

  • the present patent application refers, as indicated in its statement, to a loom or a weaving machine.
  • the present invention refers to a weaving machine, of totally new design, which, essentially, is studied to simultaneously manufacture two independent, parallel and vertical fabrics; are also and essentially common to these two fabrics, very numerous and main functions of the weaving of the machine.
  • object of the invention weft crushing, weft insertion control, crowd formation, weft density adjustment and engine control are common to both. fabrics.
  • This new design which also allows easy and convenient access to the two fabrics, also allows a significant reduction in motive force, then also, more remarkably, a total floor area occupied by the machine and a manufacturing cost per unit of fabric produced, in comparison with the higher performance machines known and currently marketed for the manufacture of the same textile articles. It is, on the other hand, a machine which, by the simplicity of the mechanical solutions designed and by the characteristic, already indicated, to be common for the two independent fabrics - significant number of the main weaving functions - presents a relatively reduced cost price, which logically has a much lower damping factor for the fabric manufacturer.
  • Another very important characteristic of the weaving machine, object of the invention lies in the ease with which it can adapt to the precise type of fabric which it is intended to produce.
  • the new machine can adapt to very large fabric widths, and a modular leaf control system is provided, which allows to reconcile the number of modules required with the density of the fabric to be manufactured. .
  • the weaving machine, object of the invention is studied, essentially, to simultaneously weave two independent vertical and parallel fabrics, having for this purpose, a rigid frame 1-1 'and next to which symmetrically, two warping beams 2-2 ', a unique crowd forming mechanism 3, which simultaneously forms two crowds 4-4', a single leaf 5, to which two opposite combs 6-6 'are attached, controlled by the mechanism that we will study later, and two weaving beams 7-7 '.
  • Figures 2 and 3 show one of the modules which, according to a characteristic of the invention, prepare to actuate the leaf.
  • the leaf fixed to two, three or more vertical columns 8, distributed over its length adequately and the number of which will depend on the width of the fabric to be woven and the density of weft of this fabric.
  • Each of these vertical columns remains in position to slide freely in the axial direction, between two limit positions which correspond to the limit positions of maximum advance and maximum return of the leaf, guided in this movement by some extreme elements 9-10, which may , obviously, to present any structure considered appropriate, and which are integral with the upper uprights 1 'and lower 1 of the frame, respectively.
  • all of the columns 8 which support the leaf 5 are actuated by the same axis 11, suitably coupled to the general control motor. of the machine, and advantageously broken down into a succession of sections coupled one after the other. It is understood that the mechanical connection between the axis 11 and the columns 8, with a view to transforming the rotary movement of the latter into a vertical reciprocating movement of the others, may be effected by means of a relatively large number of separate mechanical solutions, all of which should be included in the protection of this registration.
  • this movement transmission will be carried out, in each module, by means of a pinion 13, integral with the axis 11, which will mesh with a toothed wheel 12, which, by means of the connecting rod 14, will print in column 8 the indicated movement back and forth. All this mechanism will preferably remain housed in a casing 15, fixed on the upright 1, which will also support the guide elements 10 of the column, forming a compact assembly, which can be mass produced, being incorporated! the machine, during the assembly process, to the number that the weaving characteristics, in each case, recommend when using the machine.
  • the weaving machine, object of the invention is prepared to produce two independent fabrics for each of its two weaving faces, and the leaf will be actuated by three columns or control modules, which will remain located, respectively , the outside of the edges of said fabrics and on the strip or central zone of separation between them.
  • none of the columns indicated should cross the meshes which determine the evolution of the threads for the formation of the crowd.
  • the area of the said columns which is in contact with the meshes 16 may be broken down into two or more arms , parallel, 8'-8 ", of reduced section, and / or may be subjected to any surface treatment, such as chrome plating or the like, which improves its sliding conditions.
  • FIG. 5 is shown schematically, according to what has been said, the relative movements of the leaf, the weft inserters and the two crowds along which these inserters move.
  • FIG. 4 there is shown in solid line the leaf in the position A, which corresponds to the limit position of maximum advance or crushing, and in dotted line position B, which corresponds to the opposite limit position, maximum return.
  • FIG. 5 these two limit positions A and B are shown in dotted lines, the leaf being located (in solid line) in an intermediate position C, which corresponds to the first phase of the return movement of the leaf, when the introduction of the inserters into the crowds begins.
  • FIG. 6 the position A is shown in dotted lines, the leaf being located (shown in solid lines) in the limit position B.
  • the evolution of the wires d warping is calculated so that by the time the fulling occurs (fig. 4), the crossing has already taken place and the opening of the crowd has already started, which is fully open at the start of the return of the leaf ( Fig. 5), and already closes when the leaf occupies its maximum return position (fig. 6).
  • the evolution of the warping threads is calculated so that they are the same threads which, following an evolution in accordance with the movement of the leaf, are constantly applied against the sides of the corresponding inserter, which is kept pressed, by simple gravity, on the comb, guiding its movements through the crowd.
  • the shedding mechanism is common for the two independent fabrics, vertical and parallel, which the machine weaves separately, and, according to the invention even, the control of the beams is carried out positively, through a set of rigid elements and belts, with their corresponding guide pulleys, imparting to them a horizontal movement back and forth, from a head of machine control.
  • Figure 7 there is shown schematically a precise practical realization of a determined heald 18, which one could, as it is logical, present there any structure considered as suitable, forming a part of the heald equipment superimposed, whose number and whose evolution would vary, according to techniques already traditional in the textile industry, depending on the specific type of fabric you plan to manufacture in this case.
  • the constitutive frame of the heddle 18, to which the meshes 16 are fixed, which include the eyelets 19, is actuated alternately, transversely, and in alternately opposite directions, by means of the two rigid rods 20 -20 ', located on either side thereof, parallel to its longitudinal uprights, and joined together by their ends by means of a toothed belt 21, which engages at least one wheel toothed 22 or, preferably with two toothed wheels 22-22 ', which rotate alternately in opposite directions, actuated from the machine head by means of any known device for selection or set of taffeta.
  • each of the 20-20 'tigccs is coupled to the corresponding amount of the boom by means of a series of belts 23-23' (the number of which will depend on the warping tension which in each case we propose to make evolve), with its corresponding guide pulleys 24-24 '.
  • the control of the boom will be carried out positively in both directions, eliminating any mechanical fatigue and obtaining maximum precision.
  • the inserter itself 17 is located at the end of a flexible strip 25, while in the representation of Figure 9 it occupies the end of a "lance "rigid 26.
  • the mechanism comprises a part - constituted by all of the kinematics - which is mounted on the fixed frame of the loom, and a part, constituted by the inserter and its direct control organ, which is mounted on the leaf, following its movements.
  • the control of the inserter is effected by means of a toothed wheel, in which the flexible band 25 or the rigid clamp 26 mesh, shaped by corresponding racks.
  • This wheel is mounted together with the leaf 5, this to be mounted directly on a support or extension 28 integral with the latter, or to be connected to the latter by means of any suitable mechanical system for transmitting the movement, describing precisely a back and forth movement in an arc of a circle, which can, for example, be defined by an arm 30 which rocks on a fixed axis 31, and a guide 29.
  • the toothed wheel 27 is integral with a pinion 32 , which is connected, by means of a toothed belt 33, with a toothed wheel 34, which rotates on the axis 31, fixed to the frame of the machine, and subjected to a rotary movement of alternately opposite directions from the general motor control of the loom, by means of a transmission mechanism, of any suitable type, mounted as a whole on the frame.
  • the weaving loom being composed of two inserters (one for each of the two vertical and parallel fabrics which are woven simultaneously), the mechanisms of transmission described must be provided in duplicate.
  • two opposite and equal toothed wheels 34 will be mounted, each of which will actuate one of the two inserters indicated.
  • the "lance" or rigid clamp 26 which always remains meshed in the toothed wheel 27, has at its free end, opposite to that occupied by the insert- tor 17, a pulley or stop 36, which slides along a fixed inclined or arcuate track 37, so that it presses on the wheel and on this track, remains constantly horizontal, exactly aligned with the wing.
