Definitions

  • a clearing system for cleaning the rollers of a drawing frame, particularly the carrier-lever-mounted top rollers of a drafting system is disclosed.
  • the clearing system comprises an endless clearing belt driven by being passed through the nip of at least one pair of rollers of the drafting system.
  • Means is provided for supporting the endless belt on the carrier lever.
  • the supporting means includes guides for guiding said belt, means for tensioning said belt when in an operative location and means for holding said guides and said tensioning means on the carrier lever.
  • the endless belt merely tangentially contacts the other rollers to be cleaned.
  • This invention relates to a clearing system for cleaning the rollers of a drawing frame, particularly the top rollers of the drafting system which are mounted on the carrier lever arm in such a frame.
  • a fiber sliver is submitted to draft between two or more pairs of draft rollers.
  • the back rollers revolve at a lower speed than the roller pairs following in the direction of draft.
  • the bottom rollers of each pair are generally of solid construction, consisting of metal, and they are axially fluted.
  • the top rollers are provided with jackets made of some flexible material, usually an oil-resistant rubber, cork or leather.
  • the jackets of top rollers and draft belts have in recent times been principally made of synthetic rubber. These materials have a smooth surface and they are outstandingly suitable for the drafting of fiber slivers and rovings, but they have made the problem of cleaning when using fixed clearers more difficult.
  • Another object of the invention is to provide a system that will avoid the accumulation of fiber waste in the above-described undesirable forms.
  • Yet another object of the invention is to provide a system which avails itself of the advantages of a continuously moving clearing system without requiring a special drive means.
  • a still further object of the invetnion is to provide a clearing system which can be easily inspected and cleaned with a minimum of interference with the process of spinning.
  • a clearing system for cleaning the rollers of a drawing frame particularly the carrier-lever-mounted top rollers of the drafting system, which comprises on a carrier lever holding means for guides and tensioning means of an endless clearing belt driven by being passed through the nip of at least one pair of rollers of the drafting system, while merely tangentially contacting the other rollers that are to be cleaned.
  • a preferred feature of the invetnion consists in hingeably attaching the holding means to a small saddle member fitted over the top of said carrier lever, the point of hingeable attachment being located between the top back roller and the next top roller in the direction of draft.
  • the saddle member to which said holder for the clearing belt is attached may preferably be horizontally slidably adjustable on said carrier lever.
  • the guides and tensioning means of the endless clearing belt may be slidably adjustable on the holder parallel to the carrier lever.
  • the tensioning means may have the form of a separate roller on a tensioning arm hingeably mounted on a horizontally slidably adjustable slide on said carrier lever.
  • the endless clearing belt itself may with advantage consist of leather. artificial leather. plastics. rubber or some other appropriate flexible material.
  • FIG. 1 is a side view of a carrier lever and top rollers cleaned by clearing belts according to the invention, the belts being shown slack;
  • FIG. 2 is a plan view of the arrangement according to FIG. 1;
  • FIG. 3 is a side view of top and bottom rollers and of the clearing belts according to FIG. 1 under tension
  • FIG. 4 is a side view of a form of construction modified with regard to the tensioning of the endless clearing belt.
  • FIGS. 1 and 2 there is provided in conventional manner a carrier lever 1 which requires no detailed description as the use of such levers in drafting machinery is well known in the art.
  • the carrier lever l carries a small saddle member 2 fitted with a holder 3 on each side. Connection of each holder 3 to the saddle member 2 is by screw means 8.
  • the hingeably mounted holder 3 has a slot 9 in which the guiding and tensioning roller 1 1 or some equivalent tensioning means as well as several belt guides 10 are horizontally slidably adjustably mounted.
  • the saddle member 2 is releasably affixed to the carrier lever 1 by one of the screw heads 6 or by other equivalent means.
  • the saddle member 2 which is designed to fit over the carrier lever l is formed with a slot 7 in its horizontal web.
  • the saddle member 2 might be releasably affixed to the carrier lever 1 by some other type of quickrelease clamping or screw means.
  • the adjustability of the saddle member 2 and the hinged affixation thereto of the holder 3 ensures that the operator will not be held up or impeded when the drawing frame is in use for spinning.
  • the hinge of the holder 3 is located between the top back roller 4 and the next top roller 12 in drafting direction.
  • the weight of the holder 3 and of its guide and tensioning means land 11 is usually sufficient for ensuring a satisfactory contact pressure of the lower run 5' of the belt on the top rollers 12 of the carrier lever 1. In case of need an additional weight or a compression or tension spring could be provided.
  • the endless clearing belt 5 is driven by being led around the top back roller 4.
  • the top back roller 4 on the carrier lever 1 has a larger diameter than the rollers 12. Consequently the speeds of rotation of roller 4 and rollers 12 differ. Since the endless clearing belt 5 is driven by the more slowly rotating top back roller 4, relative movement and friction occurs between the endless clearing belt 5 and the more rapidly revolving rollers 12, and the top draft belt 13, and their relative movement has a back-rubbing effect.
  • the endless clearing belt 5 which'is flexibly but nevertheless very safely guided picks off lapping fibers and has a positive polishing effect on the rollers 4 and 12 besides being self-cleaning.
  • the correct tension of the clearing belt 5 can be set and readjusted by means of the guiding and tensioning roller 11. This roller 11 could be replaced by a hoop or like means.
  • FIG. 4 A form of construction which differs with regard to the manner in which the endless clearing belt 5 is guided is shown in FIG. 4.
  • the guiding and tensioning means in this instance consist of a separate guiding and tensioning roller 1 1' located behind the top back roller 4 and mounted on the end of a tensioning arm 11" which is horizontally slidably adjustable on the carrier arm 1.
  • the tensioning arm 11" is deflectable about a hinge in the arrowed directions.
  • the upper run 5 of the endless clearing belt 5 may be guided over upwardly directed guide means pivoted to the holder 3 or the carrier lever 1.
  • the endless clearing belt 5 it is possible for the endless clearing belt 5 to be adjusted to different roller positions.
  • An endless clearing belt 5 for long fibers can be shortened by deflecting the guide means to make the belt suitable for short and medium length fibers. Since the disposition and upward deflection of guide means in .the form of arms carrying rollers are already known in the art, a detailed description will not be required.
  • the above-described clearing system can also be applied to the fluted bottom rollers of a drawing frame, as already mentioned.
  • the suspension and method of driving the endless clearing belt 5 require some modifications.
  • the endless clearing belt '5 is driven by a separate top roller and the bottom back roller.
  • the endless clearing belt 5 runs underneath and in contact with the fluted bottom rollers 14 of the drawing frame.
  • the cleaning effect of the endless belt 5 on the fluted bottom rollers 14 of the frame is exactly the same as that obtained on the top rollers 4 and 12 of the carrier arm 1.
  • said supporting means including guides for guiding said belt, means for tensioning said belt when in an operative location and means for holding said guides and said tensioning means on said carrierlever,
  • tensioning means is in the form of a separate roller on a tensioning arm hingeably mounted on a horizontally slidably adjustable slide on said carrier lever.
