Definitions

  • the web condenser - or "condenser” for short as it is called in carding - is a complementary apparatus to the card set, and its function is to divide the web coming from the finisher card, as it leaves the doffer, into a plurality of ribbons having the same width and count. These ribbons then undergo an operation of rubbing in which the textile fibres are gathered and compacted into a cylindrical shape to form rovings strong enough for the next processing stage. The rovings are in fact normally collected onto spools which are then used to feed the spinning machines.
  • the condenser comprises:
  • each tape is guided around one of the rollers in the space between two successive tapes running around the other roller; the tapes that travel around the top roller and enter in a downward direction emerge on the bottom roller, also in a downward direction, and vice versa.
  • the web coming off the doffer is fed between the take-in rollers, or rather between the opposing tapes, it is cut by these tapes into ribbons which follow the tapes along their path from the rollers to the rubbing leathers.
  • French Patent no. 1,143,965 describes, however, an arrangement which may be defined as a "horizontal condenser" in which the card web is guided in a downward direction between a pair of horizontally adjacent take-in rollers and then the ribbons are fed to a plurality of rubbing leathers which are also horizontally adjacent.
  • the web arriving from the finisher card (which is located above the horizontal condenser) is then fed directly to a spinning machine located beneath it.
  • Figure 1 is a diagrammatic rendering of the final part of a card set, in which the finisher card C of the set, the doffer P and the condenser D can be seen.
  • Figures 2a and 2b illustrate a known kind of condenser (for example according to BE-A-564,197), in which arrangement a pair of take-in rollers 1 and 2 are vertically arranged in contact with each other. Guided around these rollers are the tapes 3: the arrangement illustrated is of one tape for every two rovings (but the same considerations apply for an arrangement with a single tape for all the rovings), where each tape is guided around an endless path passing from the take-in roller 2 around the smaller rollers 4, 5a or 5b and 6 (towards the lower rubbing leathers 7a and 7b), then around the roller 8 and back to the roller 2; from here around the take-in roller 1, then onto the smaller rollers 9, 10a or 10b and 11 (towards the upper rubbing leathers 7c and 7d), and from here around the roller 12 and back again to the roller 1, where it resumes its journey around the take-in roller 2.
  • the tapes 3 the arrangement illustrated is of one tape for every two rovings (but the same consideration
  • the rubbing leathers - which, as is known, are given a forward and parallel movement for roving transport and opposing sideways movements for rubbing - convert the ribbons into rovings which are then wound onto the bobbins or spools 13.
  • This figures also shows that, compared with the width in plan view of the rollers 1, 2, denoted l 1 , the total width l 2 occupied in plan view by the spools 13 is noticeably greater: this is in order to allow for the lateral separation, fan-wise, of the rovings as they leave the rubbing leathers and for their winding onto the spools separately from each other, that is avoiding superimpositions.
  • the condenser device which radically alters the vertical condenser design used hitherto by arranging the take-in rollers adjacently in a horizontal plane and the aligned banks also horizontally, while the card web is fed vertically both to the take-in rollers and to the rubbing leathers, which latter are arranged such that their rubbing planes are vertical.
  • the two take-in rollers 15 and 16 are horizontally adjacent and there are eight banks approached individually through the two series of rollers 17 and 18, which are adjacent in horizontal succession (rather than vertically one above the other, the form adopted in all prior art condensers). These eight banks feed the ribbons to the rubbing leathers 20 whose working surfaces are oriented in vertical planes.
  • each tape is guided in a closed loop which begins for example at roller 16 and, travelling inwards, passes around the roller 15 and then (travelling to the left in the drawing) passes around the smaller rollers 17 and 17a or 17b, then around the rollers 18a or 18b, or else 18c or 18d, and then around the rollers 19 and back to the outer side of the roller 15; from here the tape, passing under the roller 16 in an inward direction, runs (travelling to the right in the drawing) over the rollers 17 and 17c or 17d, then over the rollers 18e or 18f, or else 18g or 18h, then around the rollers 19 and back again to the outer side of the roller 16 to resume its path underneath the roller 15.
  • These cloths are made of a special material, for example Transilon, and are very thin, have smooth surfaces without the least asperity and are treated to make them antistatic; these are mounted on and travel around perfectly cylindrical rollers and maintain the integrity of the web, keeping it free of folds or creases, exactly as it emerges from the doffer.

  • These cloths are made of a special material, for example Transilon, and are very thin, have smooth surfaces without the least asperity and are treated to make them antistatic; these are mounted on and travel around perfectly cylindrical rollers and maintain the integrity of the web, keeping it free of folds or creases, exactly as it emerges from the doffer.
  • the horizontal condenser system overcomes all the problems of the prior art in relation to the forming of the fan as seen above with reference to Figure 2b.
  • the horizontal condenser enables the web to be subdivided over a number of banks distributed lengthwise along the delivery axis of the card, which means that no fan need be formed at all.
  • Figure 4 shows that the transverse width requirement l 2 of the spools arranged two by two is no more than the width l 1 of the card web.
  • the roving 41 emerging from a pair of rubbing leathers 42 descends under gravity in a downward direction to a transfer roller 43, passing via a roving guide 44.
  • the roller 43 is parallel to and in contact with a spool CA which consists of the winding of the rovings 41 onto a spindle 45 that acts as a rigid supporting base.
  • the function of the roller 43 is therefore on the one hand to transfer the roving onto the spool, and on the other hand to drive the spool round by simple peripheral contact.
  • the roving 41 is controlled in its descent by the roving guide 44 which oscillates in an essentially vertical plane (arrow Fg in Figure 6), which corresponds to the plane of alignment of a series of rovings descending from the rubbing leathers.
  • the roving guide 44 oscillates in an essentially vertical plane (arrow Fg in Figure 6), which corresponds to the plane of alignment of a series of rovings descending from the rubbing leathers.
  • each cheese is equal to the product of the number of banks multiplied by the width of the tape.
  • horizontal arrangement of the condenser it is possible, as already stated, to use a sufficiently large number of banks that the rovings can be fed in a straight line towards the spools so that no fan need be created.
  • an oscillating spool supporting system Adjacent to and underneath the roller 43 is an oscillating spool supporting system: this is formed by a first pair of arms 46 attached pivotably to a common shaft 46a parallel to the axis of the roller 43. At each free end of these arms 46 is a groove in which the two opposite pin-shaped ends 45a of a spindle 45 rest. When winding begins, the arms 46 are raised to their full extent (the position indicated by the dot-dash line 46') and the spindle 45 is resting directly on the roller 43 (position 45"').
  • the spool CA grows in diameter and the arms 46 swing downwards anticlockwise to keep the spool periphery in constant contact with the transfer roller 43 with a controlled pressure (the control of this pressure will be considered later), eventually coming to the position shown in solid lines.
  • the change-over unit also comprises a feeder 49 for holding and inserting spindles 45 which is composed of a trough 49a and two opposing guides, each formed by a first oblique or almost horizontal guide part 49b and a second curved guide part 49d whose centre of curvature is on the axis of the roller 43, with an interposed resting and releasing device 49c.
  • the trough 49a can tilt about one of its axes 49'a, which is parallel to the axis of the roller 43, in order to insert and position a spindle inside the guide 49b.
  • the spindles are engaged by the ends 45a of their shafts and are guided freely downwards purely by means of gravity, initially to a position where they stop and wait 45', and later to the starting positions 45" and 45"', as explained below.
  • the automatic change-over unit is completed by the following parts:
  • Figure 7 shows an alternative embodiment which in part is simplified in comparison with that shown in Figure 5, but which requires more floor space, for example up to 900 mm. Identical or equivalent parts are indicated here by the same reference numerals. The following therefore reappear:
  • This alternative also has the pair of arms 47 oscillating as one about the common axis 47a but does not have the arms 46.
  • the spool CA is moving directly on the arms 47, which are held up in an inclined position (indicated in solid lines in Fig. 7). They are then swung downwards (arrow F) into position 47" only during the discharging of the completed spool, under the control of control means (not shown).
  • the pins 45a projecting from the ends of the spindle 45 rest freely on the top surface of the arms 47, on which they can rotate. Because of this support the spool CA moves automatically, as it grows in diameter, along the arm 47 towards the end furthest from the axis 47a.
  • a shoulder or tooth 47b formed on the top edge of the oscillating arm 47 acts as a safety stop, specially in the starting position.
  • FIG 8 shows still another alternative embodiment which, at least in certain respects, is also simplified: here too, parts identical or equivalent to those shown in Figure 5 are indicated by the same reference numerals. The following therefore reappear:
  • the arms 46 oscillating as one on the common axis 46a, are L-shaped: the top part of the L pivots at 46a and is basically rigid, while the lower part is formed by a telescopic part.
  • This part which during the winding of the spool CA is retracted, carries grips (not shown in any greater detail) at its ends for gripping the pin ends 45a of the spool.
  • the arms 46 swing anticlockwise from the starting position 46' to position 46" at the conclusion of the winding. Having reached this position, the arms 46 are again briefly swung towards the discharging position 46"', where the spool CA is briefly separated from the roller 43 and is ready to be discharged.
  • the telescopic system of the lower part of the arm 46 is now actuated: it grows longer in a downward direction, as indicated by the dot-dash lines 46"", taking the spool to position CA' where it rests in the support 51 of the carriage 52.
  • restarter bar 54 is not supported by oscillating arms (in contrast to the two embodiments shown in Figures 5 and 7) but engaged by its ends with a transporting system formed by two belts 61 travelling around rollers 62, at least one of which is powered.
