Definitions

  • This invention relates to a machine for treating (scouring and/or fulling) fabrics particularly of vegetable or synthetic fibres in open width, of the type provided in succession with at least one tank, means for widening the fabric rising from the tank, means for transporting the widened fabric and a counteracting surface positioned within the path of movement of the fabric so that the fabric strikes against it.
  • the main object of the present invention is therefore to centre the fabric after its widening such that the aforesaid drawbacks do not occur even when operating at high speed and to prevent the fabric adhering to the transporting means by wrapping around them.
  • a further object is to provide effective centering means of lesser technical and constructional complication and hence of acceptable cost.
  • the machine for wet-treating fabrics in open width comprises a usual metal tank 1.
  • the ends of the fabric to be treated are sewn together in the usual manner so that the fabric forms a ring.
  • the direction of movement of the fabric is indicated by the arrows A and B.
  • the fabric passes through a conventional widener 2.
  • a conventional widener 2 It comprises two identical rollers 3, 4 driven by an electric motor, not shown, and supported for example by the sides of the tank.
  • One of the rollers is visible in the detailed view of Figure 2, in which it can be seen that, starting from its centre line Z1, it possesses two helical projections, one right-handed and the other left-handed, indicated respectively by 4* and 5.
  • the two rollers are supported on the sides of the tank by means of two arms 7 and two pins 8, one arm and one pin being positioned at each of the two ends of the rollers 3, 4.
  • a helical gear 9 is keyed onto a pin emerging from the tank and engages a worm, not shown, operated by a handwheel, also not shown, in order, inter alia, to enable said rollers to be correctly positioned relative to the fabric T, the position being correct if the fabric adheres to the two rollers.
  • the fabric After passing through the widening device 2, where the fabric is widened by the action of the opposing helical projections 4*, 5 on the rollers, the fabric passes to a centering device 10.
  • This centering device comprises at least one idle roller 11 covered with elastic material, eg rubber, able to exert a certain friction on the fabric T.
  • elastic material eg rubber
  • This roller is projectingly supported between two end plates 12 connected together by a cross-member 13.
  • the cross-member is supported at each end by pairs of plates 14 via a hinge pin 15. Each pair of plates is supported lowerly by a pin 16, which is rigid with a fixed cross-member 17.
  • the assembly formed by the cross-members 13, 17, the plates 14 and the pins 15 and 16 forms an articulated parallelogram which is moved by a double-acting pneumatic cylinder 18 hinged to a support 19 rigid with the cross-member 17 and whose rod 20 is hinged at 21 to the upper cross-member 13.
  • the fabric T passes from the idle roller 11 to a fabric centering detection station 22.
  • This station comprises an arrangement of means, photoemitters and photoreceivers, for example light emitting diodes (LEDs), photodiodes, photoelectric cells and the like, positioned to correspond with the longitudinal edges of the fabric when ideally centered and extending transversely.
  • LEDs light emitting diodes
  • photoelectric cells photoelectric cells
  • a signal is hence produced which when suitably amplified causes valve means to operate in order to drive the double-acting pneumatic cylinder 18 in the direction to zero the off-centering.
  • the device 7 is shown in Figure 7 and is described in detail hereinafter with reference to that figure.
  • FIG. 4 shows very schematically both the widening device 2A and the centering device 10A, which coincide with those shown in the preceding figures.
  • the fabric T encounters a pair of cooperating grooved rollers 40, one idle and the other driven, which are pressed against each other.
  • the arched teeth 41 of two comb structures 42 extend into the relative grooves, the teeth of the lower structure being the longer and accompanying the fabric towards a motorised device 43, in synchronism with the preceding, and consisting of three grooved rollers 44, 45, 46, belts 47 moving within their grooves.
  • a grooved idle fourth roller 48 presses on the underlying roller 44 under the thrust of a pneumatic cylinder, not shown, within its grooves there extending endless belts 90 which pass within the grooves of a further preferably driven roller 91.
  • the roller 91 corresponds basically to the roller 70 (of Figure 7), and the belts 90 to the belts 47D, and in the embodiment of Figure 4 fixed detachment bars 71 are provided, although not shown, interposed between the belts.
  • detachment or separation bars 49 are interposed comb-like between the belts and are fixed at their ends to cross-members 50.
  • the bars 49 are arched and project beyond the plane containing the belt portions extending between the rollers 44, 45.
  • the embodiment shown in Figure 5 comprises a tank 1B receiving the fabric T, the widening device 2B and the centering device 10B with its sensors 22B.
  • the fabric leaving the sensors 22B passes about an idle deviation roller 50* to enter a bath 51, then passes between two presser rollers 70, one idle and the other driven, these being provided to exert a pressure on the passing fabric so as to drag it.
  • the fabric then reaches a device Z of Figure 7 and from here is launched against an adjustable counteracting surface 29B before falling into the tank.
  • the embodiment of Figure 6 comprises the widening device 2C, the centering device 10C with its sensors, and reversal rollers 60, the fabric T passing between two rollers, a lower large-diameter one 61 and a smaller diameter one 62.
  • the former is motorized while the latter is idle and exerts on the former a pressure, for example by means of a pneumatic cylinder.
  • the fabric then passes through the device Z of Figure 7, the components of which are consequently indicated by the same reference numerals followed or not followed by a letter.
  • Figure 7 shows the device Z (associated with the band 28 of Figure 1), comprising the grooved roller 48A, 48B cooperating with belts 47D passing about a further grooved roller 70 cooperating with interposed detachment bars 71 similar to the bars 49 (of Figure 4).
  • the roller 48A, 48B cooperates with the grooved roller 44A, 44B, the grooves of which receive the belts 47 between which the fabric detachment bars 49 extend.
