Definitions

  • the invention relates to a raising machine, of the type comprising a raising roller, carrier drum, an intake roller for the input of a piece of fabric to be raised against the drum and a takeoff roller for the output of a piece out of the drum.
  • This invention concerns a process and means to optimize the utilization of the operative surface of raising roller carrier drums of raising machines and the like.
  • raising machines and the like comprise at least one drum including a number of raising rollers each one driven to rotate each around its axis and altogether around the axis of the drum as parts carried by the same.
  • a fabric intake roller and a fabric takeoff roller are provided with their axes parallel to the raising roller carrier drum axis so as to include a convex angle with vertex at the axis of raising roller carrier drum of about 290 degrees.
  • FR-A-89593 discloses a raising machine of this type.
  • the fabric length runs around intake roller, raising roller carrier drum and takeoff roller, the fabric length engages the raising roller carrier drum along a 290 degrees arc which corresponds to the surface of the raising roller carrier drum, which raising rollers, comprised in such arc, keep into raising working engagement with the fabric loop being fed thereupon.
  • Working effectiveness depends, among other factors, upon pressure urging the fabric upon the raising rollers and the pressure, at its turn, is a direct function of fabric feeding stretch and an inverse function of raising roller carrier drum diameter. Moreover such a pressure is not constant all over the raising rollers engaged by the fabric. In fact, the raising working pressure is relatively low at the first raising roller, i.e.
  • the one being closest to the intake roller and thereafter increases up to a constant value which is maintained along an angle of about 120 degrees.
  • the pressure rapidly increases along the top central part of the fabric loop and then, symmetrically to the increasing trend, decreases along next 120 degrees and at takeoff roller it assumes the same value than at the intake roller. Due to this unsteadiness of radial centripetal raising working pressure the diameter of the raising roller carrier drum can not be designed smaller, while a true effectiveness of raising working takes place only when the pressure is comprised in a very strict optimal field. In fact, when lower pressures, as at fabric intake, and too much higher pressures, as in correspondance of the top of the fabric loop occur, the result is substantially null.
  • the solution is characterised by the fact of comprising at least two pairs of intake and takeoff rollers (4,5';4',5), in which the intake and takeoff rollers (4',5') of each pair are placed so that the planes passing through the drum axis and the respective intake and takeoff roller axes of each pair define an angle, so that the arc of the piece of fabric extending between the intake roller and the takeoff roller is pressed agains the drum (1) with a pressure sufficient for the raising, and by the fact that the leading speed of each intake and takeoff rollers (4,4',5,5') of each roller pair is independently adjustable.
  • a known raising machine comprises substantially a raising roller carrier drum 1 which is rotatable about a drum shaft 10 and carrying on its substantially cylindrical periphery a number of raising rollers 11 and 11'.
  • Raising rollers 11 and 11' rotate in the same direction, each about its axis but each is provided with raising fillets which teeth points are pointing in opposite direction referred to the raising fillet teeth point applied to the previous and next raising roller.
  • the fabric lump to be worked e.g.
  • the fabric lump 2 partially worked on its side 2', could be worked on the same side by intaking the fabric lump in another machine (Figure 2) as the one described of the same line comprising two (M2, M3) or more machines or the leading end of fabric lump 2 could be attached to the rear end of same to provide a loop to be run indefinitely completing the raising operation.
  • Figure 2 This arrangement is shown in Figure 1 and is such that the fabric lump 2 is carried again on the chute 3.
  • At least one additional takeoff roller 5' and preferably at least one additional intake roller 4' are provided.
  • the same raising roller carrier drum may engage two or more surfaces of the same fabric lump or of more separate fabric lumps: as many as the pairs of intake-takeoff rollers.
  • the raising machine comprises two pairs of intake and takeoff rollers.
  • the machine comprises a first pair having an intake roller4 and a takeoff roller 5', and a second pair having an intake roller 4' and a takeoff roller 5.
  • the intake roller 4(4') and the takeoff roller 5(5') of each pair are placed so that the planes passing through the drum axis and the respective intake and takeoff roller axes define an angle, so that the arc of the piece of fabric extending between the intake roller and the takeoff roller is pressed against the drum with a pressure sufficient for the raising.
  • the raising machine advantageously comprises a fabric turnover device which acts on the fabric between the takeoff roller 5' of one of said pairs of roller and the intake roller 4' of the other one of said pairs.
  • the same piece of fabric is passed simultaneously between both pairs of intake and takeoff rollers in order to be raised on both its sides.
  • each intake roller 4' and each takeoff roller 5' is driven by the same variator 40" and 50" driving the partner roller of the pair. Since, as known, between each variator 50" and 40" and the driven roller respectively 5, 4, a reduction gear 50, 40, are provided also between variators 50", 40” and rollers 4', 5' respectively, pendular reducing gears 40', 50' are provided. Pendular position of each reducing gear is adjustable by a device 7, 7', e.g. comprising a toothed segment 70, 70' a driving worm 71, 71', a driving rod 72, 72' and a knob 73, 73'.
  • each pulley 74, 74' of pendular reducing gear and/or the one driving it through belt 58, 58' may be of the expandible kind so that the feeding speed of rollers 4', 5' may be changed about the speed rate of rollers 4 and 5 of the same pair.
