Definitions

  • the present invention relates to a machine for manufacturing fancy yarns. It also relates to the new type of fancy yarn obtained from such a machine.
  • the invention relates more particularly to an improved machine making it possible to obtain, from at least two threads, both fancy threads having localized effects such as flamed, buttons, loops, as fancy threads having color and / or threads in which one of the constituents forms a core completely covered by the other constituent, the effects thus obtained are preferably linked by means of an additional thread known as a "binding thread".
  • the invention also relates to the new type of wire obtained by the implementation of this machine.
  • the core wire supplied with the parade enters the upper hollow spindle carrying the coil supporting the effect wire.
  • the rotation of the coil surrounds the effect thread around the core, a needle or any other equivalent system possibly being used depending on the effect to be formed, then the intermediate thread thus formed passes inside the second. hollow spindle, the effect being linked by the binding wire coming from the coil carried by this second spindle.
  • means making it possible to modify the speed of passage of the various constituents of the fancy yarn, such as modification of the speed of the intermediate yarn and / or of the winding speed are used.
  • means for winding up the fancy yarn formed characterized in that the control shafts of the core and effect yarn deliverers and of the winding system are driven individually by synchronized motors which are controlled by a computer controlling a divider + converter converter in numerical control frequency so that said wires can either become effect or soul.
  • the machine according to the invention will be described in an installation comprising, arranged on either side of a common support frame, two series of identical working positions. Consequently, the same references will be used to designate the same members of two symmetrical positions. Furthermore, this installation comprises, for each working position, a single hollow spindle and three effect and core wire deliverers, but it is obvious that it is not going beyond the ambit of the invention to produce a machine of similar design comprising several successive hollow spindles and / or more or less than three core and effect wires. In addition, in accordance with the invention, the three elementary wires indifferently form a soul or effect, but it is obvious that it would not go beyond the scope of the invention to produce a similar machine in which one of the wires would constitute permanent soul.
  • the creel is a conventional swiveling creel (deformable parallelogram technique), in order to facilitate the operation of placing the full reels and removing the empty reels.
  • the creel (2) in the position to the right of the frame (1), the creel (2) has been shown in its normal working position while in the position located to the left of the frame (1), said creel (2 ) has been shown in its loading position.
  • the wire feeders (10,11,12) and the call provider (16) of the fancy wire formed are deliverers of the positive drive type, each deliverer being mounted on a line d 'independent shafts (10a, 11a, 12a, 16a) controlled, the control being carried out by means of an electronic assembly, controlled by a programmable microprocessor whose structure and operation is clearly shown in the block diagram illustrated in FIG. 2.
  • Such an electronic control headrest makes it possible, in accordance with the invention, to control the shafts (10a, 11a, 12a, 16a) so that the supplied wires (6,7,8) can indifferently form effect or soul.
  • the speed of the shafts (10a, 11a, 12a) must be adjusted so that the speed of one of the call providers (10a, 11a or 12a) is indexed to the speed of the call (16a) (or the winding system 17 if the machine does not have a delivery device (16) downstream of the hollow spindle) while the other two delivery devices have, in turn, a speed greater than this calling speed but by no means inferior.
  • the drive shafts (10a, 11a, 12a, 16a) as well as the drive shaft of the winding system (17) are driven individually by synchronized motors (for example with a permanent magnet) and are controlled by a computer. controlling, in numerical control, a divider + frequency converter assembly. As shown in Figure 2, each motor is controlled by a converter and a frequency divider. The intermediate power circuits of the converters are preferably connected to a single DC power supply obtained from the AC network. The speed of each of the motors is synchronous with the frequency of their respective converter; the speed setpoints are obtained from a quartz clock whose very stable frequency is divided by each of the dividers and applied -directly in digital to each converter.
  • the microcomputer produces extremely precise speed ratios by continuously changing the division factor of each divider.
  • a screen is associated with the assembly to allow the operator to interact with the machine.
  • this spindle is a conventional spindle with individual control (motor spindle). Furthermore, in order to facilitate the effect of the wire, downstream of this hollow spindle (13), a false twist spindle is preferably driven independently of said hollow spindle.
  • the machine according to the invention has numerous advantages, among which we can cite not only the possibility of producing conventional fancy yarns but also and above all new types of yarns in which the components alternately form soul and effect. .
  • This machine has a very high reliability and the speed control is carried out with very high precision.
  • it is not only possible to produce new products but also to work very delicate wires given the precision of the adjustments (voltage in particular) given by the control system. .
