Definitions

  • This invention relates to devices for reducing the width of the sliver, used in mechanisms 'for drawing textile slivers.
  • the reducing device has, in thedirection of the current of fibres, a position which depends on its supporting mechamsm and which must be arranged'as close as possible. to the pair of drawing rollers in order to ensure an efficient action of the re- "ducing device. This is very diflicult in practice, and when the correct position is obtained, it does not last, since at the slightest deformation of movement of the supporting mechanism, the reducing devices cease to occupy correct posit-ion and no longer work properly.
  • This type of reducin device may be called therefore a floating reducing device since it is not connected to any supporting member but is perfectly free and merely exposed to the action of the sliver which guides it and causes it to slide whilst resting with its bottom face on the lower'drawing roller. Moreover the reducing device according to the invention is always drawn forward by the front air of these rollers and bythe very jet 0 fibres which passes through its interior during the working of the drawing mechanism.
  • the reducing devlces are connected together in twos by means of a horizontal couling.
  • the corresponding reducing device will not stop its movement of lateral displacement, but on thecontrary the said movement will continue under the action of the ad joining reducing device, and when the broken sliver is introduced again, it will find the reducer in the position which corresponds to the position of the sliver at the moment in question and will automatically pass into the reducer.
  • each reducing device must be capable of freely oscillating round the coupling rod in order not to lose its floating or free position.
  • auxiliary part which may have the shape of a fork which, on the top drawing roller being raised, will hold the two reducin g devices by means of their coupling rod, thus preventing them from dropping on the back of the bottom drawing rollers.
  • This hook or holding part need not be employed in machines such as slubbing frames in-which the top drawing roller is never removed without stopping the machine.
  • Figure 1 is a vertical section through the central plane between two adjoining mechanisms, showing the application of the said reducing devices to a mechanism with great draft, with endless belts or hands.
  • Figure 2 shows in a similar manner the application of the said reducing devices to a mechanism with a great draft in which the holder for the fibres is a set of rollers of small diameter.
  • Figure 4 shows in perspective, looking from the right and from the top, a set of two reducing devices of open type.
  • Figure 5 shows in perspective, looking from the right and from the top, a set of two closed reducing devices for thick slivers.
  • M is the sliver which is being drawn
  • .A are the members for feeding the said sliver, constituted by a pair of rollers a.
  • E are the drawing members which are also constituted by a pair of rollers c
  • R are generally the holding members which deliver the said sliver direct to the drawing rollers e and at the same time hold it back in order that the fibres seized by the drawing rollers 6, should not pull theother fibres of the sliver which, following the feed movement of'the sliver, have not yet been nipped by the drawing rollers in question.
  • the said holding organs are constituted, in a manner already known, by a'pair of endless belts, and in the construction of Figure 2 also in a manner already known, by a pair of rollers of a small diameter arranged very close to the drawing rollers e.-
  • the sliver reducing device 1 is situated in the usual way between the said holding organs R and the drawing rollers 0.
  • the said recess 31 is sufiiciently large to enable the reducin de vices 1 to turn round the geometrical axls'of the rods 2 and to adapt themselves freely to the front drawing roller not shown in the said Figures 3 and 4.
  • top drawing roller limits the forward position of the reducing devices, and therefore the latter are not held by the fork, but when the top roller is removed, the reducing de- Vices are pulled forward by the movement of the bottom roller and the coupling tube 3 comes in contact with the two branches ⁇ l1 bent downwards of the part 4., so that the set of reducing devices 1, rods 2 and sleeve 3 is thus held fast.
  • Figure 5 is shown a set of two closed tween centres of the reducing devices, for the purpose of reducing the length of the rods 2.
  • the set of rods 2 and the tube 3 can be mounted within a tube of a larger diameter not shown in the said figures, for the purpose of protecting the coupling mechanism and strengthening the tube 3 weakened by the recesses.
  • the fork 4 of Figure 3 may be replaced by a similar part made of a plate of brass or other inoxidizable material.
  • the said part of stamped out plate must be provided with a central slot at its vfront end in order to allow the tie member to pass.
  • the material of which these reducing'devices are made may be any desired, provided that it is hard and inoxidizable and allows the finest possible polishing.
  • a reducing device in front of the said holding members which in such a case play also the part of drawing members.
  • these reducing devices may be used in multiple drawing mechanisms in which various successive drawing operations are eflected, for instance in mechanisms with several pairs of endless belts or of rollers. In such a case a reducing device will be used in front of each pair of members which act as drawing members.
  • I claim v 1 In a drawing mechanism for textile slivers, drawing cylinders for the slivers, a pair of floating reducers resting upon the lower drawing cylinders, and means for connecting said reducers together to permit the reducers to move toward and away from each other.
  • drawing mechanism for textile slivers drawing cylinders for the slivers, a pair of floating reducers resting upon the lower drawing cylinders, and means for connecting said reducers together to permit the reducers to move toward and away from each other, said reducers having a groove in the upper part thereof to receive the sliver.
