  • the present invention relates to apparatus for attenuating and winding strand form of filaments of heat softenable material and has particular relation to apparatus for attenuating, forming and winding glass fiber strand material.
  • the spindle shaft has been driven by a motor by means of a belt drive or other mechanical coupling. Although satisfactory for many operations, the slippage occuring in the coupling is undesirable in a fiberglass forming operation where the speed of the spindle is gradually reduced as a package of strand is formed to provide a substantially constant attenuating and winding force.
  • strand winding apparatus is constructed such that the collet on which a forming tube and thus a package is received is directly driven by a motor.
  • a shaft is supported by spaced, enclosed bearings intermediate its ends, such that its ends are cantilevered beyond the bearings.
  • the arrangement and spacing of the bearing support of the shaft and their relation to the length of shaft are such that there is less whip and less deflection of the shaft as compared with prior art direct drive winders.
  • One cantilevered end of the shaft receives the motor armature and a motoi field construction is supported in circumferential relation about the armature, such that the motor of the assembly is essentially bearing-free.
  • the other cantilevered end of the shaft receives the winding collet on which the forming tube is received and on which strand is collected.

  • the size transfer surface in the applicator 36 may be a rotating roller 38 or a moving belt having a film of the size applied to it.
  • the fibers 24 pass over the roller or belt 'at some'tangential location for momentary contact with the sizing solution to transfer the solution from the applicator to the fibers.
  • An example of a suitable size applicator is showri in US? Pat. No. 2,873,718. I
  • each succeeding layer may be substantially the same length as the preceding layer or may be of shorter length than the preceding layer. In the latter case, the end of each succeeding layer terminates short of the endof each preceding layer. The latter wind may be accomplished by shortening successive strokes of the forming tube, as is known in the prior art.

  • the shaft housing composed of housing elements 58 and 58A is mounted on the support 82, as is shown in FIG. 2. Because of the described arrangement, i.e., the shaft and housing conhe cones 22 at The shaft 56 extends beyond the front bearing 60A and has attached to this cantilevered portion the collet 28 which received thereon the forming tube 26, before described.
  • the collet 28 is constructed of spaced, front and rear collet rings 68A and 68B, jointed by a body 70 received on the front cantilevered shaft portion. Suitable means are provided for locking the collet 28 to the shaft 56.
  • Each of the collet rings 68A and 68B is provided with a projecting portion 72 which retains segmented collet fingers 74.
  • each finger has sides which include an angle of approximately 30 so that there are usually 12 fingers for each collet. These rings are loosely held by the portions 72, so that they can move radially under the influence of centrifugal force.
  • the outer surfaces of the fingers receive the forming package 26, generally a paper or plastic tube. Movement of the fingers 74 radially outwardly insures retention of the forming'tube on the collet; movement radially inwardly permits easy removal of the forming tube.
