Definitions

  • ring yarn is a good quality type of yarn which is more resistant and thinner comparing to other types of yarn.
  • ring yarn has been considered as an ideal yarn for so long, microscopic analysis has shown that the structure of this yarn was not that perfect and the amount of fibers not embedded to the yarn structure were in fact much more than of thought.
  • compact yarn spinning was emerged as a method that provides a distinctive quality yarn.
  • a compacting area is provided right after the main drafting area to keep the fibers together as much as possible and in a parallel way, the yarn is kept under control via a roller and then sent to twisting. Thus the area called "spinning triangle" has almost been removed.
  • the object of this invention is to provide a system to modify the current ring spinning machines to manufacture compact yarn.
  • one spindle of the machine or some spindles may not produce standard compact yarn.
  • the aim of this invention is to lessen or eliminate the problems encountered in the current compact yarn systems and to provide an easy modification system for current ring spinning machines to manufacture compact yarn.
  • it will be possible to modify the ring spinning machines without a substantial structural amendment and in a reversible way to manufacture compact yarns.
  • this modification there will be no need to amend the parameters such as drafting pressure, drafting intervals, etc.
  • a strong plate spring is used in order to press the delivery top roller upon the front bottom roller and to carry and fix the system to the current pendulum arm. That spring is not fastened to the pendulum arm directly but is attached to the top roller carrier arm. The pressure thus evolved increases the stable pressure of the top roller for drafting and creates improper drafting. Also, it creates additional load on the front bottom roller and middle bottom roller which in return forces the motor- reductor groups which drive these rollers and increases power consumption.

  • a compacting area is provided by placing a mechanical compactor on the front bottom roller between the top roller and delivery top roller.
  • the material of the compactor must be wear resistant but less than the front bottom roller (6) .
  • the bulge diameter of the front surface of the compactor (10) that is firmly seated onto the front bottom roller (6) must be equal to the diameter of the front bottom roller (6) .
  • the proposed modification system is carried by the pendulum arm frame (1) (See Fig. 15) .
  • the diameter of the delivery top roller (8) is reduced and thus the deformation of the yarn geometry is eliminated to a greater degree.
  • top roller rod (9) a different type of delivery top roller rod (9) is used. Namely, the rod of the top rollers is normally stable and top rollers are rotated on the rod by the ends placed into bearings.
  • the rod (9) holding the delivery top rollers (8) is centrally born and rotated. Delivery top rollers (8) are fixed to the rod (9) holding them (See Fig. 5) .
  • the diameter of the delivery top rollers (8) made of flexible material is 19 mm or smaller.
  • This bearing system (36) can be any type of bearing or a sliding bearing.
  • the delivery top rollers (8) and compactors (10) are fixed rigidly to a system carrier (3) which is stably connected to the U-carrier (2) in order to prevent the sliding and lateral movements thereof. (See Fig. 1,3 a, 3 b) .

  • the distance between the delivery top roller (8) and front bottom roller (6) will be equal and thus the pressure applied to the front bottom roller (6) by the delivery top rollers (8) and compactors (10) will be equal as well.
  • the system carrier (3) ( Figure 3a) is hung loosely to the intermediate piece (15) fixed between the arms (12) of the U-carrier (2) internally (See Figure 4a, 4b, 4c) ( Figure 1, 15) . In this manner, the lateral movements of the system carrier (3) are prevented.
  • the outer distance between the arms (23) of the system carrier (3) is shorter than the internal distance between the arms (12) of the U-carrier (2) . Thus, this provides a smooth rotation of the system carrier arms (23) between the U-carrier arms (12) .
  • the axis of the intermediate piece (15) is parallel to the axis of the front bottom roller ( ⁇ ) .
  • the body of the intermediate piece (15) that stays between the two arms (12) of the U-Carrier(2) is cylindrical but the ends thereof is quadrate.

  • a rod (9) holding the delivery top rollers (8) and a spring rod (20) holding the compactors (10) are attached to the ⁇ system carrier (3) .
  • a protrusion (22) in the shape of a reverse, outward "U” letter is provided centrally on the plate spring rod(20) .
  • the system carrier (3) is pushed down towards the front bottom roller (6) by means of a plate spring (17) which is hung to the intermediate piece (15) and thus the delivery top rollers (8) and spring steel rod (20) along with the compactors (10) press upon the front bottom roller (6) (See Fig. 1,15) .
  • the pressure exerted by the spring that is pressing the delivery top rollers (8) and thus compacted yarn towards the front bottom roller (6), is as minimum as to prevent the rear movement of the twisting after delivery top roller (8) .
  • Helical spring or a pneumatic system can be replaced with the plate spring (17) .

  • the spring steel rod (20) that holds the compactors (10) also presses the compactors (10) to the front bottom roller
  • the pressure of the spring is sufficient enough to hold down the compactors (10) to the front bottom roller (6) at the front side.
  • the hooked end (35) of the spring steel rod (20) is inserted into a bulge (21) provided in the compactor (10) and also on the compactor channel (19) and the compactors (10) are placed onto the rod (20) loosely.
  • the protrusion (22) provided on the spring steel rod (20) loosely enters into the grooves (45) (Fig. 3a) on an undulated structure (44) mounted between the arms (23) of the system carrier (3) and the position of the compactor rod (20) and thus the compactors (10) are stabilized.
  • the width of those grooves (45) is wider than the diameter of the rod (20) and the distance between the axes is equal to the out-to-out distance of the protrusion (22) .
  • Spring steel rod (20) is attached to a circular channel (24) provided at the ends of the system carrier arm (23) through a flexible channel (25) diameter of which is smaller than the diameter of the rod (20) (See Fig. 3a, 7, 8) .

  • the bottom zone between the bands (43) is hollow except the compactor channel (19) area and thus it is out of touch with the front bottom roller (6) . Consequently, the friction surface is diminished and besides the elastic range of the spring steel rod (20) is obtained.
  • Figure 6b shows the cross sectional view of the compactor (10) .
  • a round single piece press rod (inflexible rod) (27) made of a relatively non-resilient material can also be used.
  • Rod (27) made up of two pieces (27a, 27b) and these pieces are connected through an intermediate piece (28) and it is inserted through the channels (63) on the arms (23) of the system carrier (3) .

  • Single piece rod (27) presses the compactors (10a, 10b) attached to its ends onto the front bottom roller (6) thanks to a plate spring (30) mounted to the system carrier (3) .
  • the position of the compactor (10a, 10b) is adjusted at one direction via circlips (34) on the rod (27) and via abutting the roller (29) to the channel of the single piece rod (27), which has a smaller diameter than the roller (29), at the other direction.
