Definitions

  • the invention relates to an apparatus for the dry treatment of a fabric
  • first and second chambers adapted to contain respective supplies of open width fabric, said first chamber being for an infeed supply and said second chamber being for an outfeed supply; means gradually introducing the fabric in said first chamber; means gradually withdrawing the fabric from said second chamber; a flat section duct adapted to contain the open width fabric and communicating said chambers one with the other; blowing means for blowing air into said duct; heating elements for said air; a set of slots in each of the ends of said duct to allow the passage of said air inside the duct; two sets of gates alternately to regulate the direction of the air towards one of the sets of slots; drive means for said gate sets, closing the gates of one of the sets at the same time as it opens those of the other set.
  • Spanish patent ES-A-532.408 of the present applicant discloses a method and an apparatus for treating fabrics, based on the alternate flow of air transporting the fabric from one chamber to the other. Nevertheless, said patent does not precisely disclose the automatic system for reversing the air flow.
  • the apparatus being of the type described hereinabove, is characterised in that each of said chambers is provided with a generally horizontal wall on which the fabric being collected in the chamber rests, forming successive folds which generally do not overlie each other, part or all of said wall being capable of undergoing a slight rocking movement depending on the weight of fabric supported thereon, said rocking movement activating the said gate set drive means.
  • the apparatus comprises a first chamber 2 for a fabric 4 disposed open width.
  • An infeed supply 6 of said open width fabric may be formed in said chamber 2.
  • the fabric 4 is disposed, for example, in a folded pile 8, although it could also be wound, forming a roll. From the pile 8 (or, as the case may be, from the roll of the like) the fabric 4 is gradually fed into said first chamber 2 by a device 10 comprising rollers 12 which may guide an endless belt 14.
  • the device 10 is driven by a motor 16 and may be rocked by an arm 18. As stated, the fabric enters the apparatus generally continuously, albeit slowly.
  • a second outfeed chamber 20 Opposite to said first chamber 2, there is a second outfeed chamber 20, in which an outfeed supply 22 may be formed and from which the fabric 4 may be withdrawn, also gradually.
  • the fabric 4 passes through the space 24, being transported by rollers 26 above a conveyor belt 28 provided with orifices to allow air to pass therethrough.
  • a cam 30 with a connecting rod 32 alternately moves an arm 34 suitably to dispose the already treated fabric 4 forming a pile 36 of folded fabric.
  • the fabric outfeed is generally continuous, albeit slow.
  • the chambers 2, 20 are connected together over a flat section duct 38 adapted to contain the open width fabric 4.
  • a flat section duct 38 adapted to contain the open width fabric 4.
  • the duct 38 is preferably disposed generally S-shaped, i.e. having a first run 40 aligned with the first chamber 4, a first 180° elbow 42 followed by a second run 44 ending in a second elbow 46, also of 180°, connected to a third run 48 aligned with the second chamber 20.
  • both chambers 2, 20 face each other and that the duct therebetween be short, for example, having a length of about 1 metre.
  • the duct 38 normally has a width of 1.8 to 2 metres, without any limitative meaning being placed on these dimensions. When the fabric to be treated is wide, the duct is used without any modification. Nevertheless ( Figure 3), the duct 38 may be divided lengthwise by a partition 50, thereby allowing the simultaneous treatment of two fabric pieces 4. This is of particular interest for the treatment of goods knitted on circular machines which provide tubular fabrics having a width of about 0.8 metre.
  • the apparatus comprises also blowing means 52 (preferably two fan units) adapted to blow air into said duct 38 and said means 52 are driven by a motor 53.
  • blowing means 52 preferably two fan units
  • each end portion 54, 56 of the duct 38 (respectively adjacent the chambers 2, 20) is provided with a set of transverse slots 58, 60, inclined relative to the duct 38, allowing the access of air towards both faces of the fabric, without creating turbulence.
  • the slots 58 communicate with a branch 62, while the slots 60 communicate another branch 64 and both branches may communicate with a space 66 reached by the air blown by the blowing means 52.
  • gates 68, 70 adapted to make or break the communication between the space and the branches, such that when gates 68 are open, the other gates 70 are closed.
  • the gates 68 are connected over conventional means with a return gate 72, such that all are simultaneously in the same position, open or closed.
  • the gates 70 are connected to anothet return gate 74, as shown in Figure 2.
  • All the said gates are actuated, for example, by a hydraulic mechanism 76 rotating in 90° and shafts 78 provided with bevel gears 80.
  • Each of the chambers 2, 20 is provided with a generally horizontal wall 82 on which the corresponding supply 6, 22 of fabric rests.
  • the wall 82 is preferably only a part of the bottom of the respective chamber and each wall 82 may rock slightly, depending on the weight of fabric supported thereby.
  • the said rocking movement is measured by a sensor or other device 84 adapted to emit an electrical signal activating the gate drive means (for example, the hydraulic mechanism 76).
  • the rocking wall 82 is only a part of the chamber floor and, preferably, is the part of the floor farthest removed from the duct 38.
  • the apparatus also comprises a heating element 88, close to the space 66, as well as a filter 90.
  • the apparatus is provided with an accessory formed by baskects or cages 92 made from rods having an inlet end 94 adaptable to the communication space of the duct 38 with each chamber and the section of the said baskets or cages 92 is generally the same as the section of the duct 38.
  • the cages 92 are provided with a curved outlet end 96 facilitating the gradual infeed and outfeed of the fabric.
  • the first thing is to feed the fabric 4 by hand, fully flat over the rollers 12, switching the motor 16 on for a period of time of about one minute, whereby a sufficient length of cloth is deposited in the right hand side of the chamber 2.
  • the leading end of the fabric is led by hand up to the level of the slots 58 and when the blowing means 52 is started up (with the gate 68 connecting the space 66 to branch 62 being open), the current of air transports the fabric to the chamber 20, from where the fabric is led by hand over the rollers 26 and endless belt 28.
  • the chamber 20 (like the infeed chamber 2) is provided with a permeable enclosure area 86 removed from the duct 38, the air also transports the fabric 4 to this removed area and consequently practically all the supply 22 bears on the rocking wall 82.
  • this supply reaches the predetermined weight referred to above (coinciding with a substantial exhaustion of the infeed supply 6), the wall 82 rocks and acts on the device 84 which emits an electrical signal for the hydraulic mechanism 76, whereby the gates 68 and 72 close and gates 70 and 74 open.
  • the motor 16 causes the gradual entry of untreated fabric and the fabric outfeed mechanism withdraws the treated fabric, said fabric being treated continuously.
  • the characteristics of the treatment are determined by the adjustable speeds of the infeed and outfeed motors, by the fabric speed, adjustable in dependence of the air blown by the fan, by the adjustable temperature provided by the heating elements. Therefore, a very uniform surface finish, a high drying performance and a high productivity and cheapening of costs are achieved within a wide range of possibilities.
  • the fabric As its moves through the duct 38, the fabric is not subjected to mechanical stress or to harmful abrasion with the apparatus surface, since such movements take place practically without contact with the duct walls, due to the air transport in one direction or the other.
  • the fabric is not subjected to any stretching either at the infeed or at the outfeed. Furthermore, reversal of the air flow is triggered by a collection of the cloth, which does not imply any stretching either, contrarily to what happens with other embodiments in which the air flow is reversed by movement of a lever on exhaustion of the fabric in one of the chambers, said fabric engaging the lever and thereby being undesirably stretched.
