Definitions

  • My invention relates to a device for winding tubular or can cops which comprises an axially fixed revolving spindle stump over the free end of which the cop continuously is stripped 01f continuously by the yarn which is fed onto it.
  • Winding devices of this type when compared with the known devices fitted with an axially reciprocating spindle, afford the advantage of eliminating the soiling of the material to be wound, which is un avoidable with reciprocating spindles. Furthermore the drawback is overcome which occurs in winding comparatively long cops by means of these known devices, of the cop being withdrawn from the spindle only with difficulty.
  • winding devices fitted with the axially immova ble spindle stumps suffer from the drawback that, especially in winding comparatively long cops or cops of comparatively fine yarn material, bending of the cop cannot be avoided, so that such long or fine cops can be made only on winding machines having vertical spindles, the attendance of which machines, however, is very complicated.
  • the contraction of the inside of the spool ceases and becomes loosened from the spindle core.
  • the cop is then no longer centered and is influenced by the centrifugal forces arising from the high speeds 01' operation, 3000 to 4000 R. P. M.
  • the cop disposes itself eccentrically to the spindle and develops a strong centrifugal force which is capable of damaging the apparatus and the spindle. Aside from the possible damage to the machinery, the texture of the cop becomes loose and thereby unusable.
  • the object of the invention is to provide a guide for the spindle stump which on the one hand prevents a throwing of the cop and on the other hand affects the pressure relations in such a manner that an easy stripping of the spool from the spindle guide is possible.
  • the desired 75. object is attained by providing a suitable prismatic or cylindrical extension of smaller cross section than the spindle stump upon the latter.
  • the cross section of this smaller spindle portion is so chosen that it is adapted to the contracted opening of the spool after the latter is stripped from the main spindle stump, which contraction arises from the elasticity of the yarn material.
  • the cross section of the extension is so chosen that the movement of the spool thereon is not hindered and, on the other hand, no more play than is absolutely necessary for this movement is provided in order to prevent a centrifugal throwing of the cop.
  • winding machines of conventional construction having horizontally disposed spindles operating at speeds of 3000 to 4000 R. P. M. without fearing that the cops will bend and tear apart and with assurance that the growing cop is capable of movement along the spindle, and the removal thereof by hand after it is finished may be effected easily and without hindrance.
  • FIG. 1 is a side elevation of one of the spindle units, showing a spool core in section, at the beginning of the winding operation
  • Fig. 2 is a side elevation corresponding to Fig. l and showing the winding of the spool in an advanced stage
  • Fig. 3 is a side elevation of a spindle unit showing the spool in its finished condition preparatory to its withdrawal from the spindle, and
  • Fig. 4 is a side elevation corresponding to Fig. 3, showing the simple withdrawal of the spool from the spindle guide.
  • - 9' denotes a casing which encloses a gearing as commonly used with cop winding machines and by which a reciprocating motion is imparted to the yarn guide 10.
  • the gearing is driven by friction discs 11 and actuates a shaft 12 mounted in the casing 9.
  • the other end of shaft l21 is” formed with a spindle stump 13 of prismatic cross section.
  • a bevel roller 14 is revolubly mounted on a shaft 15 in a carrier 16 below the spindle stump 13, and acts as a feeler.
  • the spindle stump 13 carries an axial spindle extension 17 of prismatic or circular cross section but of somewhat smaller diameter than the former. Only a rotary movement is imparted to the spindle unit by the driving mechanism.
  • the winding operation is the same as with the known winding devices of this type.
  • a hollow auxiliary core 24 is used which is put on to the spindle stump 13, the yarn being clamped between these two parts.
  • the device is set in motion, with the yarn guide deposing yarn layer on to yarn layer always on the same place and with uniform reciprocating stroke.
  • the feeler roller 14 comes to act from the beginning and owing to its being mounted stationarily causes a continuous outward shifting of the cop as it is formed, thus stripping off of the cop from the spindle stump 13.
  • the cop is supported during the winding operation by the extension 17 of smaller diameter over which the growing cop gradually and loosely is shifted.
  • the cop 25 After the cop 25 has been formed in this manner, it can simply be removed by hand, as illustrated in Figures 3 and 4. This removal does not offer any difiiculty even with very long cops as only a small portion of the cop is carried by the spindle stump 13, whereas the extension 17 of smaller cross section serves only as a loose" guide from which the finished cop can easily be removed.
  • an axially stationary and rotatable spindle consisting of a main portion and an extension on said main portion, means for winding yarn upon the main portion of the spindle and means at said mainportion for shifting the wound cop along said spindle, said extension having a substantially uniform cross section slightly smaller than that of the main portion to permit an effective guiding and easy shifting of the cop along the spindle.
  • an axially stationary and rotatable spindle consisting of a main portion and an extension on said main portion, means for winding yarn upon the main portion of the spindle and means at said main portion for shifting the wound cop along said spindle, said extension having a substantially uniform cross section of the same contour as the main portion and slightly smaller than the cross section of the main portion to permit an effective guiding and easy shifting of the cop along the spindle.
  • a rotary spindle consisting of a main winding portion and an extension on said main portion having a substantially uniform cross section slightly less than that of the main portion to permit an effective guiding and an easy movement of the cop along the spindle.
  • a rotary spindle consisting of a main winding portion and an extension on said main portion having a substantially uniform cross section of the same contour as the main portion and slightly less than the cross section of the main portion to permit an effective guiding and an easy movement of the cop along the spindle.
