Definitions
- the problem which the invention proposes to solve is to produce a textile support having one or more decorative effects.
- a support woven generally on a Jacquard loom or a mesh support produced on a loom with hooks is used.
- Such techniques require the use of heavy organs and complex kinematics.
- the loom In the mesh technique, the loom generally implements a barrel and a bar guide, which constitute a mechanical assembly, requiring a significant processing time, and a reduced production rate.
- the wire reserve capacity is very limited, so that it is difficult to use large section wires. Last but not least, these techniques are ill-suited economically and in terms of speed.
- Patent FR 2 339 011 discloses a process combining the techniques of the loom and those of the hook loom. Essentially, this document teaches the execution on a trade, of a basic textile support, and simultaneously, the realization of any decorative effect. The decorative effect is blocked on the textile support by means of meshes which are executed simultaneously with said support. However, the solution for achieving these objectives is not satisfactory, the means of implementation being complicated, so that the results obtained are not satisfactory.
- the object of the invention is to remedy these drawbacks in a simple, safe, efficient and rational manner.
- the problem which the invention proposes to solve is to obtain a textile support with decorative effects, using rapid looms, including without shuttles, to obtain very high production rates, by combining weaving and mesh.
- a process has been designed and developed for the automatic production of a textile support with decorative effects, according to which: - the textile support of based,
- the binding needles are raised to form the blocking mesh through the ply of the warp threads of the base support
- the binding needles are raised to form the blocking mesh and simultaneously, in a circular arc movement, the thread of blocking mesh is moved by means of passers to cross the path of said needles, which has the effect to form the blocking mesh of the fancy weft,
- the binding tapes for forming the blocking mesh are moved in translation, which has the effect of causing the wire to be pressed fancy weft against said needles,
- the binding needles for forming the blocking mesh are lowered, which entrain the mesh forming wire, by creating a loop of mesh by tightening the fancy weft,
- the binding tapes for forming the blocking mesh are moved in translation for a new cycle.
- the device comprises:
- the means for distributing the fancy frame (s) comprise at least one wire guide, supporting said frame, said wire guide being coupled to a transfer carriage movable in translation and whose command is controlled by a programming unit.
- the thread guide (s) are integral with guide bars for translational movement of the carriage, perpendicular to the warp threads of the basic textile support, the carriage cooperating with a system drive coupled to a programmable motor.
- the means for controlling the binding needles for forming the blocking mesh are constituted by an oscillating support receiving the said needles mounted in a needle bar , said support cooperating with drive and movement transformation members, to subject all of said needles to vertical and translational movement, back and forth through and under the basic textile support.
- the means for subjecting the blocking thread (s) to a circular arc movement are constituted by a system of controlled rods and cranks when the support receiving the binding needles for forming the blocking mesh is controlled, said system acting by means of a link on an axis on which the supports receiving the blocking mesh wires are mounted.
- the means for moving in a rectangular movement the members capable of temporarily retaining the weft (s) of the decorative effect, are constituted by a deformable parallelogram system.
- the programmable control means able to act on the means of distribution of the fancy weft to modify will its displacement, are constituted by a stepping motor, electronically controlled integrating two parameters, namely an amplitude of the fancy weft of direction perpendicular to the warp thread and according to a movement to the right or to the left and a frequency of movements or not at each revolution of the profession.
- Figure 1 is a large-scale view showing the principle of the manufacturing method according to the invention.
- Figure 2 is a cross-sectional view taken along line 2.2 of Figure 1.
- Figure 3 is a view similar to Figure 2 of an alternative embodiment, especially at the textile support.
- FIG. 4 shows an example of the manufacture of the article according to the programming chosen.
- Figure 5 is a front view of a machine equipped with the device according to the invention.
- FIG. 6 is a top view corresponding to FIG. 5.
- FIG. 7 is a side view corresponding to FIG. 5.
- FIG. 8 shows the means for moving the binding needles for forming the blocking mesh.
- FIG. 9 shows in particular the means for controlling the members capable of temporarily retaining the frame (s) of the decorative effect.
- FIG. 10 shows an exemplary embodiment of an article obtained according to the method of the invention.
- FIG. 11 shows an example of programming of the control motor for the guide wire of the fancy weft, according to the effect decorative obtained.
- Figures 12, 13 and 14 show the clamping of the fancy weft between the back of the needles and the locking thread on the textile support.
- Figure 15 shows an example for producing loops of different amplitudes, depending on the program chosen.
- a textile support is produced on an automatic loom, of any known and appropriate type, comprising weft threads (1) and warp threads (2). Simultaneously, at the formation of the support, at least one decorative effect (3) is produced, blocked on the textile support by means of meshes (4) executed simultaneously with the base support.
- the stitches (4) are executed by needles (5), driven by a determined movement.
- the decorative effect (3) is carried out by means of a fancy weft (6).
- the realization of the basic support, by means of the warp and weft system is carried out in a completely conventional manner in combination with a comb (P), but is not described in detail, because on the one hand, this technique is perfectly known to a person skilled in the art and, on the other hand, is not part of the specific object of the invention.
- the needles (5) for binding the formation of the blocking mesh (4) are arranged very substantially perpendicular to the chain ply (2) and are integral with a needle bed (15) or bed of needles animated by a reciprocating vertical movement.
- the needles (5) rise perpendicularly through the ply of warp threads (2) of the base support.
- the needles (5) descend and disappear under the web of warp threads (2) of the base support, they are retracted under the latter at the insertion of the last pick. This deletion of the needles (5) is necessary to avoid coming into contact with the comb (P), which takes their place when arriving at the strike.
- the needle bar (7) slides in two bearings of an oscillating support (8) articulated on an axis (01).
- the needle bar (7) is connected by a crank pin (9) to a connecting rod - crank assembly (10) (11).
- This assembly (10) (11) is balanced and receives its movement from an axis (02), to secure the needle bar (7) with a vertical reciprocating movement.
- the needles (5) can be retracted under the base fabric, as shown.
- the latter is obtained by a cam system (12) mounted on an axis (13) and capable of acting on a roller (14) integral with said support and angularly offset relative to to the hinge pin (01).
- An elastic member of the spring type ensures the return of the support (8).
- the needles (5) when withdrawing, tend to block the base weft (1), by means of the mesh.
- the needles (5) When the needles (5) are under the basic textile support (1) (2), the leaf of the loom being struck, the fancy weft (6) is transferred and deposited perpendicular to the warp threads (2).
- the fancy frame (6) is supported by son guides (15) integral with a carriage (16).
- the device may have four son guides (15) each secured to a carriage (16).
- Each of the carriages is mounted to slide freely, on a bar (17) and on a parallel bar acting as a guide (18), the assembly bars (17) and (18) allow the carriage to move perpendicular to the chain (2).
- Each carriage (16) is driven by means of a toothed belt (19) mounted on a receiving pinion (20) and a motor pinion (21), wedged on the shaft of a motor (22). This arrangement is found for each of the transfer carriages (16).
- each of the motors (22) is electronically controlled by being slaved to a programming central.
- each motor is constituted by a stepping motor, employed in auto-switching of the ESCAP PP 520 type or by a direct current motor.
- Two cells with HALL effect incorporated in the motor allow this type of control.
- the program includes two parameters:
- step N ° 0 of the program which corresponds to the first cycle of the trade, the carriage is brought back to the left, to the value O.
- step N ° 1 of the program this value is maintained so that the carriage remains stationary.
- step N ° 2 of the program departure towards the value 200 pulses, corresponding to the formation of the large loop of the decorative effect and maintains this value until step of program N ° 13 where the value returns to 0, then start again at program step N ° 15 on the value 130 and return of the carriage to step 18 at the value 0, this step being confused with step 0 of the program with the first cycle.
- FIG. 11 shows an example of programming of the control motor of the thread guide of the fancy weft, according to the decorative effect obtained.
- the passettes (23) are integral with an axis (03) coupled to a rod (24) to be subjected to the oscillation movement, via a rod system (25) - crank (26).
- This rod-crank assembly is controlled by a pinion system slaved to the movements of the pin needles (02).
- the passettes (23) move with a needle gauge pitch (5) in translation, which has the effect of making the mesh (4) tackle by making it penetrate into an arrangement of needles (5), for example under the beak of this needle (FIG. 2).
- the needles (5) begin their descent as well as the passettes by entraining in their movement, the thread (4) forming a loop which passes through the previously formed stitch, to create a new stitch.
- the device comprises pins (34) arranged at the end of the needles (5) and son guides (15) receiving the fancy weft.
- These pins (34) are controlled by any known and appropriate system, to subject them to a rectangular movement.
- These pins have the effect of temporarily retaining the threads (6) of the decorative effect during the path of the thread guides (15), for example at the time of the formation of the loop.
- the device has two pins (34) working alternately ( Figure 5). The movement of the pins is combined with that of the wire guides (15) and conditions the width of the loop.
- the pins (34) are mounted in a support (35) subject to a system of deformable parallelograms consisting of links (36) (37) (38) (39) ( Figure 9).
- this mechanical system can be substituted for an electronic control which acts either on a motor with angular movements, or on an electromagnet, acting on the backward advance travel of the pin.
- Such a system is subject to the previously defined program.
- a similar electronic control moves the .picot or not perpendicularly to the warp, moving it away from or bringing it closer, to make loops of different amplitudes, in accordance with the chosen program, as shown in the example of FIG. 5 Obviously, this drawing should not be considered as limiting.
