Definitions

  • This presoak is usually carried out using equipment placed upstream of the washing installation.
  • This apparatus operates continuously and obviously should not involve any slowing down of the operation of the washing installation, so that it contains a very long length of fabric, of the order of several tens of meters.
  • This drum obviously exerts a significant braking effect, so that when, for example by means of suitably arranged feed rollers, it is called up at the outlet of the presoaking apparatus, it frequently happens that by as a result of the excessive tension thus applied to the fabric, it folds longitudinally at the same time as it inadmissibly shrinks.
  • the present invention proposes to remedy this drawback by allowing the production of an autonomous pre-soaking machine which ensures the treatment of fabrics without tension and offshore and whose construction is remarkably simplified.
  • the machine according to the invention of the kind comprising on the one hand two superimposed rows of drums between which the fabric is returned in order to pass between ramps for the spraying of the vertical strips defined on said fabric by said rows, and on the other share a series of electric motors to ensure the drive, under a constant torque of the drums of one of these rows, is characterized in that on the supply circuit of electric motors, of the variable speed and constant torque type is placed a self-transformer directly controlled by a compensating roller arranged, in a manner known per se, at the outlet of the drums of the two rows in order to be subjected to alternating displacements according to the difference in the respective working speeds of the machine and the treatment plant supplied by it.
  • the reference 1 designates the fabric to be treated by presoaking.
  • This fabric taken from a reserve shown diagrammatically in 2, is returned) ur to successively cross a station 3 for the unrolling of the selvedges and a centering station 4, the devices or mechanisms provided at said stations 3 and 4 being well known in practical and therefore does not require any detailed description.
  • the fabric 1 passes inside a tank 5 possibly filled with a liquid impregnation product, then it is guided to be successively returned vertically between two overlying rows of drums referenced 6 and 7, which thus determine on said fabric a series of vertical portions or strips oriented in parallel to each other.
  • the lower drums 7 are arranged above a tank 8, while each of the upper drums 6 is connected to an independent electric drive motor 9 of the multi-pole asynchronous type, at constant torque.
  • Each upper drum 6 is surmounted by a spraying ramp 10, all of the ramps 10 of the machine being supplied from a pipe 8a provided on the lower tank 8; the latter collects the liquid which after spraying by the ramps 10 trickles along the strips 1 'and it also receives a supply via an auxiliary pipe 12, the excess flowing through an overflow 8b.
  • the fabric 1 On leaving the last upper drum 6, the fabric 1 is returned upwards, not a perforated drum 7, but by a compensating roller 14 (fig. 1) provided substantially at mid-height between the rows 6 and 7.
  • This roller 14 is carried by lateral arms 15 articulated in the manner of flails on pivots 16 and it is the vertical displacements of said roller 14 which control the adjustable speed of the drive motors 9.
  • one of the two pivoting arms 15 extends beyond its pivot 16 opposite the roller 14 and on this protruding part 15a is attached to the end of a cable 17 suitably returned by pulleys 18 and provided at its opposite end with a tension counterweight 19 which only partially balances the weight in overhang of the aforementioned roller.
  • a cable 17 suitably returned by pulleys 18 and provided at its opposite end with a tension counterweight 19 which only partially balances the weight in overhang of the aforementioned roller.
  • the mobile armature shown diagrammatically at 20a, of an auto-transformer 20 connected to the electrical circuit which supplies all of the motors 9.
  • a switch 21 is also provided on this electrical supply circuit, the movable member 21a a of which is linked to one of the two pivoting arms 15 and is designed to selectively actuate four contactors suitably connected to the circuit. aforementioned, as will be better understood when we explain below the operation of the machine according to the invention.
  • the fabric 1 returned upwards by the compensating roller 14 is recalled downwards by a final drum 6 'driven by a motor 9' (fig.1) connected to the same general circuit as all of the motors 9. It passes through then a widening mechanism 22, advantageously constituted by two cylinders or “screws" with oblique grooves, then a centering device 23 of conventional type, before finally being returned horizontally at 24 to enter the washing installation associated with the presoak machine.
  • the movable member 21a of the switch 21 actuates one or the other (depending on whether the working speed of the presoak machine is higher or on the contrary lower than that of the treatment installation) of the two central contactors, thus short-circuiting the auto-transformer 20 by directly supplying the motors 9 and 9 'at most in one case, and by cutting the auto transformer 20, therefore the supply of motors 9 and 9 ', in the other case.
  • the machine "thus quickly" recovers the difference in speed and the automatic regulation by the auto-transformer 20 can resume in a very short period of time.
  • the assembly can be fitted with various accessories capable of improving the guiding of the tissue to be treated, its regular course and its spraying.
  • driving each drum 6 by a separate motor constitutes the best solution, it is obviously possible to connect several of these drums to the same motor.
  • the invention is applicable to any presoak operation of fabrics, in particular with a view to bleaching them.
  • the cost price of the machine according to the invention is much lower than that of conventional machines.
  • the constant torque motors 9 and 9 ′ are inexpensive and the compensating roller and auto-transformer system which controls them avoids the need for complicated and expensive control devices.
