Definitions

  • the invention relates to a spinning machine drafting system with lower rollers and with upper rollers and with Unterriemchen and Oberriemchen according to the preamble of Ansprüchs. 1
  • the present invention is based on a pneumatic Luntenverdichtungsaggregat, in which the fiber composites is summarized by sucking on a line of fibers extending along the row of holes through which air is sucked by means of induced draft.
  • This row of holes can be in a drafting roller and both in one. Under roller as well as in a top roll or in a fiber dressing leading straps be arranged. The invention is described below with reference to a device in which the row of holes is arranged in a top roller assigned straps.
  • Changing the positions of the drafting rollers is particularly simple if the bearings of the lower rollers or the holders of the upper rollers are of the same design, so that they can be easily moved to other positions and used. Also advantageous is an at least approximately the same diameter of the lower rollers of the drafting system, because thereby their peripheral surfaces are in other positions at least approximately the same height and the usually flat fiber surface remains at least approximately flat.
  • the drafting system 1 in its arrangement for compaction spinning four generally corrugated bottom rollers 2, 3, 4 and 5 made of steel.
  • the lower roll 3, which is often "tied”, i. is grooved, is wrapped by a Uriterriemchen 11, which is also performed before the subsequent pair of rollers around a turning rail, not shown here.
  • the output sub-roller 5 is usually in the punch 6, the other lower rollers, however, are mounted in slides 7, 8 and 9, which are adjustable in the punch in the direction of fiber passage.
  • the bearings of the lower rollers 2, 3, 4 and 5 are the same, so that each lower roller in each of the carriage 7, 8 or 9 or in the bearing in the punch 6 can be inserted.
  • the lower rollers 2, 3, 4 and 5 also have at least approximately the same diameter, so that when displacing the lower rollers, the drafting plane of the drafting system 1 is at least approximately maintained.
  • the lower rollers 2 and 4 are associated with normal top rollers 10 with elastic cover.
  • the upper roller 10 associated with the lower roller 3 is surrounded by a top apron 12, which is guided by a common apron cage, not shown here, with deflecting rail.
  • the drafting 1 is a Vorgarn concerned23 upstream and downstream of a yarn guide 24 and a not dargesielltes ring / rotor / spindle assembly of common construction.
  • the supplied roving 25 between the successive pairs of rollers ie the pair of input rollers 2/10, the Oberriemchenwalzencru 3-11 / 10-12 and the pair of delivery rollers 4/10 continuously refined and as a roving 17 in its final fineness of the the lower roller 5 and the compression unit 19th existing compression and output roller pair delivered.
  • warping this roving 17 has gone in the width.
  • the compression unit 19 and the lower roller 5 can be removed.
  • the remaining drafting rollers are advanced by one position in the direction of the run of the roving 17.
  • the lower roller 4 is added to the previously occupied by the lower roller 5 bearing in the punch 6, the lower roller 3 in the bearing of the carriage 9 and the lower roller 2 in the bearing of the carriage 8, the carriage 7 remains free.
  • the distances between the carriages 8 and 9 to the test position of the new output lower roller 4 in the punch 6 are adapted. Accordingly, the top rollers 10 are to be placed in the roll holder 22 of the corresponding arm 20. From Fig.
