Definitions

  • This invention relates to an improvement in or modifioation of the mechanism for drawing textile rovings or slivers claimed in our prior specification Ser. No. 384,245, now Patent No. 2,798,259. These drawing mechanisms are employed both in spinning machines and in preparation machines, in which the roving or ribbon of fibres passes through a series of successive pairs of rollers, and sometimes through other elements which accompany the fibres.
  • a small device which is interposed between two consecutive pairs of rollers, and which acts as a conductor and presser of the fibres, and at the same time as a collector of these fibres, or a condenser of the roving.
  • This device consists of a rigid frame, which depends from a fibre-conducting roller, and such roller bears upon the lower rollers of two consecutive pairs of rollers of the drawing mechanism.
  • the lower part of the frame forms a handle, to facilitate the operations of locating the device on the machine and removing it therefrom.
  • the roving bears against the lower portion of the fibre-conducting roller, and then passes through the condenser, which collects the fibres together and gives them cohesion.
  • the present invention relates to improvements in the construction and mounting of the frame that supports the conductor roller of the fibres, by means of which substantial advantages are obtained in the use and operation of spinning machines.
  • FIGURE 1 is a perspective view of the device, looked at from the side on which the fibres isue, to be seized by the front pair of rollers;
  • FIGURE 2 is a similar view from the opposite side, that is to say, the side on which the fibres enter;
  • FIGURE 3 is a view in elevation, partly in section, looked at from the exit side of the fibres.
  • FIGURE 4 is a side view of a modification, of symmetrical construction, which can be placed on a spinning machine on one side or the other indifferently.
  • This conducting and fibre-uniting device comprises a roller 1, which has in its lateral faces circularholes 2, in
  • the invention consists essentially in limiting the frame to the lower part 5, which forms the reducer or condenser 6 of the roving, and the two lateral walls 7, which project upwards from the sides of this lower part, and present on their inner faces the circular projections 3 which form the journals for the rotation of the roller 1.
  • This frame may be made of a number of pieces of moulded material, united by a screw 8, as indicated in FIGURE 1, but is preferably made in one piece of a moulded material which exhibits a certain elasticity, sufiicient to enable the two lateral branches of the frame to be easily separated by hand, thereby enabling the roller to be conveniently put in and taken out for cleaning, without it being necessary to use a screwdriver or any other tool.
  • the frame 5, 7 completely symmetrical, as illustrated in FIGURE 4, so that the roving can enter the lower reducer just as well on the one side as on the other, and so that in placing the fibre-conducting device on the spinning machine it will not be necessary to seek the side corresponding to the en trance of the roving, but it can be placed on one side or the other indiiferently.
  • the uniting or condensing of the fibres does not prove so perfect as with the arrangement of FIGURES 1 to 3, it may prove convenient in many cases, thanks to its greater handiness of manipulation.
  • the frame is easier to mould, and proves more economical owing to the smaller quantity of material required;
  • the new arrangement of the frame facilitates for the operatives the cleaning of the roller and frame during the operation of the machine, and obviates, in the cleaning operations, the giving of shocks to the frames, which frequently result in breakages of threads.
  • the frame may be constructed in one piece, thus facilitating the construction, and if a material having a certain elasticity is selected, as hereinbefore indicated, the fibre-conducting roller can easily be withdrawn, whenever this is requisite for the purpose of cleaning it, and returned to its place, without having to dismount the frame.
  • a fiber conducting roller and condenser for a drawing mechanism for textile rovings or slivers designed to be positioned between consecutive pairs of drawing rollers wherein said fiber-conducting roller bears upon the lower rollers of two consecutive pairs of rollers consisting in a fiber conducting roller, a rigid frame depending from said fiber conducting roller, a condenser for the roving forming an integral part of said frame at the lower portion thereof, two integral lateral branches upon said frame directed upwardly and located one at each side of said condenser and trunnions upon the free ends of said branches for said roller.
