Stops 33 are adjustably mounted on the disk in position to be engaged by the fingers 30 which are held against the stops by the springs.
  • the traversing disk is so positioned with respect to the strand l3 that each of the fingers 30, as it rotates with the disk, traverses the path of the strand I 3.
  • the spindle I 6 is vertical so that the spool i4 rotates horizontally and the spool is located at a lower plane than that at which the strand 13 leaves the coating device or guide I5.
  • the strand l3 extends from the guide l toward the spool in a downwardly inclined direction.
  • the rotation of the traversing disk causes each finger 30, as it moves downward, to engage the sliver or strand l3 and carry it downwardly so that it is wound spirally on.
  • the finger 30 engages a releasing device 35 'or trip in the form of a stationary stop arm or lug 35 in the path of the finger so that the latter is swung upwardly and inwardly about its pivot 3i and releases the strand as the latter reaches the lower end of the spool.
  • the finger is thrown upwardly with extreme rapidity to the dotted line position (Fig. 3) and held in such position until it passes beyond the range of the strand.
  • the strand When the strand is thus released, it immediately commences an upward movement, owing to the inclined direction in which it is being drawn to the spool as the latter rotates. As a result, the strand is wound spirally from the lower end of the spool upward until it reaches the upper end, when it is engaged by the next succeeding finger 30, which again reverses the traverse. In this manner,- the strand as it is wound on the spool is caused to travel up and down, thereby evenly distributing the material as the package is built up.
  • the speed of the traversing fingers 30 is preferably the same as the.
  • each two adjacent fingers 30 is thus substantially double the length of the package being wound. This arrangement provides for uniform and even distribution of the material. It will be understood, however, that the apparatus can be modified to provide a different ratio between the up and down traversing movements.
  • Fig. 4 illustrates a modification in which two traversing disks 23 and 23 are provided, with means for rotating them in opposite directions so that the traversing movement of the strand l3 may be positively controlled during both its up and down traversing movements.
  • the disk 23*, the fingers'30 thereon, and the trip device 35* may be constructed and operate substantially in the same manner as the disk 23, fingers 30 and trip 35.

  • the disk 23 is mounted on a shaft 43 extending through and concentric with the shaft 40.
  • the shaft 43 is driven by a belt 44 running over a pulley 45 on the shaft, the belt 44 being driven in the opposite direction from that of the belt 4!.
  • the belts 4i and 44 may be driven either by the motor which drives the spool carrying spindle IE, or by separate motors driven in synchronism or at constant speeds. Any suitable speed changing mechanism may be employed for adjusting the speed of the traversing means as may be required to provide a properly timed relation between the traversing disk and the winding spool in order to obtain an even distribution of the material as it is wound.
