Definitions

  • This invention relates to a drawing apparatus for spinningframes, comprising two co-ac'ting endless runner bands, of which the upper band runs over a top roll and a guide bar, and the lower band over a bottom roll and a guide bar.
  • the said two guide bars together form transverse guide .forks which are inserted in mounts.
  • the later are held in their position by drawing rolls.
  • the runner bands due to friction between same andthe said forks, have a tendency to take the latter along in the direction of movement of the sliver. 'It thus may happen, particularly in case of thicker drawing frame slivers and.
  • the two guide bars in accord with the present invention are mounted independently of each other, and at least the lower guide bar is adjustably positioned.
  • the position of the lower guide bars of a plurality of heads is made variable from a single common control point.
  • supporting plates may be provided at both ends of the guide bars, which are mounted rockable on a bottom roll shaft and supported, at a second point, on an adjustable base.
  • the latter preferably is constituted by a longitudinally displaceable rail which extends over a plurality of heads of the drawing frame and comprises wedgelike lugs which serve for pivoting the said plates.
  • Fig. '1 is a longitudinal cross-sectional View of a first embodiment wherein the lower guide bars are indirectly Supported .on a rail.
  • Fig. 2 is a transverse sectional view .on a smaller scale, with said rail in elevation,
  • Fig. 3 is a partial view corresponding to Fig. .1,- of a second example
  • Fig. 4 is a similar view, of a third example.
  • Fig. 5 is a top view on a smaller scale, of .the drawing frame of which .Fig. 1 .is a cross-sectional view.
  • the drawing apparatus shown in Figs. 1 and2 comprises .a stationary frame 10 comprising stands Illa in which a lower feed roll shaft Ml and a lower delivery roll .shaft '41 are rotatably supported parallel to each other. These shafts preferably extend through the whole length of the frame it and are driven .in known manner.
  • the shaft 40 carries an integral lower feed roll '42 and the shaft 4] carries an integral lower delivery roll 43.
  • a pressureroll shaft 44 is rotatably mounted .in the frame stands lila, said shaft 44 having at each drawing station, an integral lower pressure roll 4 in alignment with the feed roll 42 and the delivery roll .43.
  • each station may be referred to as the lower roll set, only one .such set being shown in the drawing although the apparatus :may comprise a large number thereof.
  • anendless runner band or apron 2 runs over the pressure roll '4 and a lower guide bar '6 .secured at its ends .in a lateral supportingplate I, which at its rear end is swingably mounted on the bottom roll shaft 44 by means of a semi-circular recess.
  • the supporting plates 1 are supported in front on .a rail 8 which is common .to the plates 1 of a plurality of heads .and advantageously extends over the entire length of the drawing -frame.
  • the rail 8 is supported on the roll stands l'fla through the 'tapering'lugs 9 provided on their bottom side.
  • the front elevation of the plates I and guide bars 6 of the lower bands 2 may be varied as desired within the given limits.
  • Supportarms are mounted each on a fixed pin 3! so as to be upwardly swingable about said pin.
  • An auxiliary saddle 29 carrying a delivery roll axle 46 is hinged to each arm 30 in a known way by a pin 41.
  • a pressure saddle 26 is hinged to the auxiliary saddle 29 by means of a pin 48.
  • axles namely, an upper feed roll axle and an upper pressure roll axle 21 are mounted.
  • the axles 45, 46 and 21 project to both sides of the pressure saddles 26 and 29.
  • the axles 45, 46 and 21 carry an upper feed roll 28, an upper delivery roll 49 and an upper pressure roll 3, re- 6 spectively.
  • An upper guide bar 5 is fixed in the pressure saddle 26 and also projects to both sides thereof.
  • Another endless runner band or apron I runs over each of the pressure rolls 3 and the corresponding end portion of the guide bar 5.
  • the plates I at their rear end possess an upper horn II for laterally guiding the upper runner bands I.
  • a corresponding lower horn serves for laterally guiding the respective lower band 2.
  • the free ends of the said horns laterally are bent off to the outside, whereby the runner bands be laterally guided with only little wear.
  • the lateral supporting plates 7 and, thus, the lower guide bars 6 are set and adjusted by a shaft I2 which is mounted rotatable in the roll stands Ma by means of eccentric rings I3.
  • the upper portion of the drawing apparatus is not shown.
  • the spacing between the guide bars is varied by a corresponding rotation of the said shaft I2.
  • the parts not shown in Fig. 3 are similar to those shown in Fig. 1.
  • the top-rolls 3 of the drawing apparatus are displaceably mounted in holders I 4 which are swingably mounted on pin 3I and supported through snubs I5 on the roll stands I 0.
  • the laterally projecting guide bar and an axle I9 are inserted in a link I8 and the said axle I9 receives at each end a top roll 3.
  • the top roll 3, which is disposed closer to the observer, and the appurtenant top band I are not shown.
  • the guide bar 50 and roll axle is for an upper pair of runner bands form a rigid carrier by means of the said link I8, and such carrier structure is displaceably guided in lateral grooves 20 and 2
  • the said grooves 2I are disposed obliquely relative to the said holders, and are provided in guide members 22 which are mounted displaceable on a bar 23 disposed on the front face of the holders I4.
  • the guide members 22 are displaceable in such a way as to permit swinging of the upper band aggregate as a unit about the roll axis I9 for the purpose of changing the elevation of the upper guide bars 50 of the runner bands I with respect to that of the said roll axis, which itself is defined by the position taken by the roll I9 as it presses the bands I and 2, with the sliver between them, against each other on the lower pressure roll 4.
  • the spacing of the guide bars 59 and 60 is increased when displacing the guide members 22 as indicated by the arrow shown, that is, towards the front top roll.
  • the lower part of the drawing apparatus is similar 4 to that shown in Figs. 1 and 2 and will not be described here again.
  • the top rolls 3 are Weighted from a pressure saddle 24 through the link I8, directly on to the roll axle I9. The weight is transmitted through a snub 25 of the link I8, which snub is offset relative to the roll axle I9, so that guide bar 50 is pressed against the lower supporting face of the groove 2 I.
  • Such grip may be set, in drawing apparatus adapted in accord with the present invention, in all the drawing heads of one and the same frame side from a single control station.
  • the adjustability of the guide bar spacing according to the present invention advantageously also is possible when the drawing frame is in operation so as to permit to set same with corresponding ease on to favourable operating conditions.
