Definitions

  • the invention relates to an apparatus for a continuous ring loom by means of which the same piece of wick is simultaneously subjected to both real twisting and drawing.
  • the stretching cylinders of said pair are at most horizontal axes, at least one of the two cylinders is rotated by a bevel gear, which, in turn, engages on a ring gear with vertical axis: the two rollers drawing being mounted on a member rotating around the vertical direction of movement of the wick.
  • Patent GB-163,353 further provides a device for simultaneous twisting and drawing of cotton, wool, silk and other textile fibers, by means of a pair of cylinders with a vertical axis, one hollow and aligned with the winding spindle, the other mounted on a sled sliding in a frame, fixed to the shaft of the first cylinder.
  • the wick which comes from the food cylinders slides around a fixed bar, then passes between the two stretching cylinders and finally, sliding on the upper end of the hollow cylinder of said pair of stretching rollers, passes , inside of it and goes to the winding spindle.
  • the grazing friction of the wire on the head of the hollow stretching cylinder opposes the low tensile force available to the spindle-winding ring group; consequently, and this especially under certain operating conditions, such as for example with a light ring and a low speed of rotation of the spindle, it can happen that the wire is recalled with difficulty inside the hollow stretching cylinder and in addition the wire tends to form loops at the exit of the stretching cylinders.
  • the wire in formation is subject to heating and to wear, which reduce its quality.
  • the present invention aims to eliminate these drawbacks.
  • the invention solves the problem of producing a device capable of simultaneously twisting and drawing a wick, which allows, despite the detours imposed on the wire in formation , a high production speed (40 m / min. and more) with a high rotation speed (10,000 - 12,000 rpm), with uniform stretching (12 m / min. equal to 40% of the feeding speed ) and with a uniformity of the wire, that is to say a regularity of its section, greater than that currently. obtained by means of the ring spinning machine and even slightly higher than that obtained by means of the self-acting loom.
  • the detours of the wire in formation are carried out without friction and, in addition, it is avoided, in a safe manner , the concentration of the stretch on a short piece of the wick and the damage caused to the wire in formation as a result of friction and heating of the wire.
  • the advantages obtained thanks to the present invention essentially consist in the fact that it is possible to work textile fibers of any type, even short and regenerated; that at a production speed equal to and even slightly higher than that of the continuous spinning mills, it is possible to obtain a quality equal to or greater than that obtained by means of intermittent looms; that it is possible to twist the wire further; that a device according to the invention is capable of being adapted to all the known continuous filier.
  • Figure 1 shows the overview of a possible embodiment of an apparatus according to the present invention.
  • This device essentially comprises a pair of rollers 2, 2 'stretchers, with vertical axes, the motor and hollow roller 2, rotating around its own axis, on command of a pulley 30 with belt 30' and the roller 2 ' presser, mounted idle on a plate 4, horizontal, rotating in a concordant and coaxial manner with said roller 2, on command of a pulley 40 with belt 40 '.
  • Said plate 4 is integral with a vertical support 41, carrying several (eg four) deflection pulleys 42, freely rotating about their own horizontal axis; two of these pulleys 42 are equidistant from the plate 4 to allow the wire in formation to pass horizontally between the two drawing rollers 2, 2 '; the other two pulleys 42 are at a distance from the plate 4 greater than that of the two first and placed so as to collect the wick 1 on its arrival from the food cylinders 11 and to direct the wire 1, at its exit from the drawing rollers, towards the hollow cylinder 2, in the vertical direction of advance of the wire 1.
  • An opening 43 is provided in said support 41 to allow contact between the two stretching rollers 2, 2 '.
  • the difference between the speed of rotation of the plate 4 carrying the pressing cylinder 2 ′ and that of the driving cylinder 2 determines the traction speeds of the wick 1 and therefore the percentage of stretching with respect to the pair of food cylinders 11.
  • the rotation of the plate 4 and of the support 41 with the return pulleys 42 determines the twist of the wick 1: the two combined movements of the driving cylinder 2 and of the plate 4 determine the simultaneous twisting and drawing of the same piece of wick 1.
  • a spindle 6 for winding the wire 1 with a ring bench 7 and a rail 8, rotating around a vertical axis which is in the direction of advancement of the wire 1 in formation and rotating in accordance with said plate 4 so as to maintain and make final the torsion effected by the drawing rollers 2, 2 '.
  • the speed of rotation of the spindle 6 will be equal to or higher / lower than that of the plate 4 depending on whether one wishes to obtain only the winding of the wire or an addition / minus modification of the importance of the twist of the wire, carried out by said pair of rollers 2, 2 '.
