Definitions

  • the present invention relates to a method and a device for withdrawing from a treatment bath, e.g., the rinsing liquid, normalizing and arranging in mesh alignment a knitted hose or other hose fabric.
  • a treatment bath e.g., the rinsing liquid
  • the meshes are normalized already at the time of withdrawal of the fabric from the bath such that they are given the desired semicircular shape which is characteristic for a relaxed mesh.
  • the fabric is mesh aligned.
  • the present invention relates to a method for withdrawing, e.g., from the last treatment bath, normalizing and mesh aligning a knitted fabric or another fabric hose; and, the main feature of the method is to be seen therein that an air cushion is inserted in the hose between the surface of the treatment bath and two rollers situated at a certain distance above said surface, the hose being inserted between said rollers for pressing out the treat- Patented Apr. 28, 1970 ment liquid which then streams down along the fabric and makes the same essentially air tight about or in the area of the air cushion.
  • the cushion of air can be provided in any one of several different suitable ways. One example would be the mere blowing or directing of a flow of air into the end of the hose at the starting operation.
  • a fan and some suitable mouthpiece also may be used for channeling the air into the hose. Should air losses occur in the air cushion, e.g., due to a hole or any other defect in the fabric, these losses may according to the present invention, be compensated for as by the disposition of a sensing means resting against the air cushion to detect changes in position thereof, which sensing means then influences a microswitch whereby a valve is electrica ly opened and compressed air is blown through a thin tube to replenish the air cushion.
  • This air jet uncovers a part of the fabric from the liquid such that in this uncovered area, air from the compressed air tube can be pressed through the fabric and into the cushion area.
  • the uncovered area is tightened after air replenishment is completed, and preferably by means of a further tube which is arranged just above the compressed air tube enabling liquid, e.g., from the last treatment bath, to be sprayed onto the uncovered area which thereby is tightened.
  • a machine for carrying the method according to the invention into effect is preferably provided with a simple folding device of known type and it is probably not necessary to describe such a device in detail since it is -well known to anyone skilled in the art.
  • the folded fabric package thus obtained from the machine is embraced by one or two elastic straps and a suitable number of such packages are placed in the spinner.
  • Waste of time and work is hereby considerably reduced and the handling of the fabric is simplified to a great extent and also so is the transfer to the drier, and the latter does not have to be provided with any transversely tensioning device any more.
  • the fabric is mesh aligned already at the withdrawal from the bath and for this reason the product does not have to be watched during its treatment in the calender in this respect.
  • the method according to the invention not only reduces the work required but, more importantly, one obtains a final product which can be used for the manufacture of garments having a considerably better shape permanence than could be previously obtained.
  • the method is also very suitable for being carried into effect at dyeing vats in which it contributes to an even dyeing and prevents the occurrence of fulling creases.
  • One of said rollers should be stationary with regard to the distance to the plane of the fabric in the transversely tensioning device and the other one should be movably supported, e.g., on a lever, in such a way that in case the air quantity in the air cushion is reduced, last mentioned roller approaches first mentioned roller and influences a horizontal arm with an adjustable counter weight. As already mentioned, the air pressure in the hose is automatically controlled by the relative position of this roller.
  • the invention also relates to a device for carrying into elfect the method described in the aforegoing and this device comprises a vat containing treatment liquid through and from which the hose fabric is withdrawn for being fed further through the press nip between two rollers so as to press treatment liquid, carried along by the fabric, out of the same.
  • the main feature of this device is that it comprises a means for forcing air into the hose at a place between the liquid surface in the vat and the rollers, and that between the liquid surface of said treatment bath and the pair of rollers, there is arranged a transversely tensioning device which may be of a well-known type and generally having the shape of a rectangular frame, the sides of which frame are arch-shaped and extend in the feeding direction of the fabric.
  • the transversely tensioning device preferably comprises a frame formed by two tubes, and advantageously on each side of this device, there is arranged a preferably elastic driving belt running over two spaced pulleys.
  • the driving belts are arranged to run while being in contact with the side of the tensioning device and thereby act to feed the hose fabric up over the tensioning device.
  • the device also comprises means for compensating losses from the air cushion and means for controlling the air compensation, the construction of which will be obvious from the following description.
  • FIG. 1 is a side elevation illustrating the principle of the invention
  • FIG. 2 is a perspective view of the same device
  • FIG. 3 shows on an enlarged scale a transversely tensioning device according to the invention
  • FIG. 4 shows a section on the line IVIV in FIG. 3,
  • FIG. 5 shows on an enlarged scale the pulley for one driving belt for advancing the hose fabric along the transversely tensioning device
  • FIG. 6 is a view from above corresponding to the view shown in FIG. 5.
  • the fabric hose is fed from a wheeled box 2 to the last treatment bath 3 in a vat 4.
  • the fabric hose 1 is fed over a driven roller 5 in such a way that some meters of the fabric always be situated within the treatment bath 3.
  • the hose 1 is withdrawn from said bath by means of two sensing rollers 6, 7 of which the roller 6 is stationary and the roller 7 is movable so as to influence a controlling means 23.
  • From the rollers 6 and 7 the fabric 1 runs over a transversely tensioning device 8 and further up between the nip of press rollers 9 and 10 for a pressing out of liquid carried along from the bath 3.
  • the fabric 1 is then fed over a roller 11 and down to a collecting device, preferably a so-called folding device 12.
  • FIG. 2 the machine is shown more in detail and it can be deduced from this figure, that the box 2 has been advanced to the treatment vat 4, and the knitted hose 1 is being fed over the roller 5 into the treatment bath 3.
  • FIG. 2 there is further depicted the most essential feature of the invention, viz. the arrangement of an air cushion 13 above the surface of the treatment bath 3.
  • This air cushion 13 acts in a most unexpected way in that the withdrawn knitted hose 1 is normalized and arranged in mesh alignment and no further measures are required for correct feeding of the knitted hose to the transversely tensioning device 8.
  • the knitted hose is fed along this device 8 by means of elastic drive belts 14, 15 which run over spaced apart sets of pulleys 16, 17, and 18, 19.
  • the volume of the air cushion 13 is reduced.
  • the sensing roller 7 is thereby swung about the shaft 20 closer to the roller 6 and infiuences the operation means 23, e.g., a microswitch, which in turn influences (opens) a tube 21 for supplying compressed air.
  • Said tube 21 directs an air jet towards the air cushion 13 and uncovers, i.e., removes liquid from a part of the surface of the hose such that air in said jet can enter the hose and compensate for air losses in the air cushion 13.
  • the transversal tensioning device 8 is shown on an enlarged scale in a front view from which it is obvious that the transversely tensioning device comprises an essentially rectangular frame having two opposed sides 24, 25 which extending in the feeding direction of the fabric 1 are arched such that the frame will be broadest at the centre, e.g., at the section line IV-IV in FIG. 3.
  • This section is shown in FIG. 4 and it is understood from the same that the frame comprises two tubes 26, 27 situated close to each other.
  • the fabric is fed along said tensioning device 8 by means of a pair of elastic drive belts 14, 15 arranged one on each side of the device and running over pulleys 16, 17, and 18, 19, respectively, arranged at opposite side ends of said tensioning device 8.
  • FIGS. 5 and 6- there is shown on an enlarged scale elevational and edge views, respectively, of a pulley 19 and related apparatus.
  • the pulley 19 is driven by means of bevel gears 28, 29 of which gear 28 is mounted on a shaft 30 of the pulley 19 and the other one 29 on a shaft 31 which is mounted in the stands 33, 34 of the device according to the invention.
  • the shaft 31 is driven by means of a belt 32 (see FIG. 2) via the roller 9 which in turn is driven by a power source, e.g., an electric motor 35 or the like.
  • the pulley 19 is provided with a medial groove 34' in which the belt 15 runs and on the side turned towards the transversely tensioning device 8 the belt 15 is pressed against the notch formed between the adjacently disposed tubes 26, 27 forming the transversely tensioning device.
  • the belt 15 runs at its upper end about a pulley 18.
  • the arrangement of the driving belt 15 has now been described at the right hand side according to FIG. 2 of the device 8 and, of course, it is the same at the left hand side but turned opposite hand or as seen in a mirror.
  • the elastic belts 14 and 15 may with advantage comprise closely wound steel springs inserted in a suitable rubber hose.
  • the two pairs of pulleys 16, 17 and 18, 19 may be driven in a Well-known manner as by means of said bevel gears on a transverse shaft and arranged in such a way that th pulleys may be displaced forth and back along the shaft such that the machine can be adjusted and be provided with a transversely tensioning device fitting the width of the fabric.
  • the upper pulley pair 16, 18 is driven in the same way as the lower pulley pair 17, 19 on a transversely extending shaft 36.
  • the two transversely extending shafts 31 and 36 are interconnected by means of a roll chain 32 and the sprockets 37, 38 are replaceable such that it is possible to obtain a certain speed difference between the pulleys 16-19, viz., between the lower pulleys 17, 19 which could be denominated feeding pulleys and the upper pulleys 16, 18 which could be denominated the pulling off pulleys.
  • the driving belts 14 and 15 When the driving belts 14 and 15 are driven such that they run along the transversely tensioning device 8 while contacting the same, they feed the fabric 1 upwardly along the same and by means of the device described in the aforegoing for driving the pulleys 16-19 the effect is obtained that the fabric structure is changed when the fabric by means of the elastic belts 14, 15 are moved along the transversely tensioning device 8 which is considerably wider at the centre than at its ends.
  • yarn will slide from a position of the yarn portions extending in the longitudinal direction of the fabric over to that of the yarn portions extending in the transversal direction of the same. During this process the length of the fabric is of course reduced.
  • the elastic belts 14 and 15 in this mechanism function in the following manner. Due to the fact that the lower pair of pulleys 17, 19 runs a little faster than the upper pair 16, 18, there will occur a certain tensioning in each belt on the outside of the upper pulleys 16, 18. The belt is somewhat stretched, but essentially maintains its thickness due to the steel spring disposed therein, and engages the V-notch in the pulley without slipping even at the highest rotation speed. However, at the inside of the lower pulleys 17, 19 the belt is locked no longer but is free to contract. The fabric caught between the frame of the tensioning device and the elastic belt is then wrinkled more or less depending on the speed difference between the feeding pulleys 17, 19 and the drawing pulleys 16, 18. Then, when the fabric thus highly wrinkled is advanced along the tensioning device frame to the broadest place, the wrinkles disappear on the fabric for. the reason that the transversal tensioning positively causes. a length reduction, in the manner described in the aforegoing.
