Definitions

  • This invention relates to a device for varying the traverse for the production of bobbins with windings tapering conically at both ends.
  • the device consists of a spindle or shaft and a movable and practically symmetrical heart-shaped cam arranged round it.
  • a traverse varying' device is employed by the aid of which the material is obtained wound in any desired predetermined form.
  • This traverse varying device may for example operate in such a way that the ends of the wound bobbins receive a conical form.
  • various traverse varying systems have already been adopted, for instance a heart-shaped cam is utilized, upon which there rests a small eccentrically arranged rollwhich makes it possible to alter the amplitude of the traverse during the winding.
  • the same object can be attained in a systematic manner by making the amplitude of the deflection of the traverseyarying regularly smaller.
  • a heart-shaped cam which may be regarded as being composed of a large number of thin heart-shaped cams which are displaced in a regular manner in relation to the axis. Owing to the fact that a different portion of the end or narrow edge of the cam is allowed to come into action each time, a modification of the amplitude of the traverse varying can be obtained.
  • the device according to the invention is characterized by the feature that the shaft is displaceable in the longitudinal direction and is connected with one or more elements having oblique bounding surfaces, which, when the shaft is displaced in its longitudinal direction, shift the heart-shaped cam in such a way that the difference between the longest and shortest radii of the cam, measured from the center of rotation, is thereby altered.
  • the device according to the invention may also be so con- For the purpose of attaining the fi Serial No. 532,386, and; in the Netherlands April 25, 1930.
  • Figure 1 shows a longitudinal section thiglough a device according to the invention
  • Figure 2 a side view, looking in the direction of the arrow in Figure '1, but with the cover removed. I
  • the shaft is denoted by 1. This is slidably arranged in a bearing sleeve 2.
  • the bearing sleeve 2 carries a flange piece 3', and encloses elongated cavities 4.
  • the flange piece 3 is formed with ledges 5, shown in Figure 2, to which the cover plate 6 is secured by means of bolts or otherwise. This cover plate is only shown in Fig. 1.
  • These rollers are according to the present invention adjustable by means of a screw 10.
  • the sliding piece 7 carries by means of bolts 11 a heart-shaped cam 12, which has a large aperture 13.
  • the shaft 1 passes freely through a notch in the cover plate.
  • a wedge piece 14- which is secured by bolts or otherwise to the shaft.
  • the rollers 8 can run along the inclined are exchangeably edges of the wedge piece 14: while the shaft 1 is being displaced.
  • a great advantage of the device according to the invention consists moreover in the fact that in a simple manner an alteration in the deflection of the traverse varying device can be obtained by inserting a different wedge piece. In this way it is at the same time pos-. sible also to modify the form of the bevel, since in place of an insertion piece with straight edges an insertion piece with more or less curved lateral surfaces is selected.
  • a traverse varying device for the production of bobbins with conical ends comprising a heart-shaped eccentric, an opening in the said eccentric, a shaft movable in a longitudinal direction and adapted to pass through the said opening, a member having inclined surfaces secured to the shaft, a bearing sleeve for the shaft, a sliding piece fixed to the heart-shaped eccentric, a slot in said sliding piece, the said member with inclined surfaces being adapted to fit into the said slot and impart movement to the sliding piece, guides on the bearing sleeve for guiding the sliding piece, and rollers secured to the sliding piece, said rollers bearing on the member having the inclined surfaces.
