Definitions

  • ABSTRACT A device for effecting tension-free wet treatment of textile material lengths (e.g., sheets, webs or the like continuous material) which comprises a wash bowl containing a predetermined level of processing liquor, a rotating perforated drum at least partially immersed in the processing processing liquor, and guide means for feeding the textile material as wave-like plaits onto the perforated drum and for removing the plaits from the drum.
  • the guide means includes a beating device for forming the textile material into the wave-like plaits on the perforated drum.
  • This device contacts the textile material above the level of liquor in the bowl, and the drum rotates at a speed which is lower than the speed at which the textile material is fed into the bowl onto the drum 9 Claims, 2 Drawing Figures Pmminma ms I 3.142.,737
  • the present invention relates to a device for effecting a tension-free wet treatment of textile material lengths such as woven fabrics, knitted fabrics, and non-Wovens of natural and/or synthetic fibers, and more particularly to such a device wherein means are provided for directing the textile material to be treated in the form of waves over a perforated drum partially submerged in a process liquor in a wash bowl.
  • fibers may be added to, or employed in the weaving of the textile material, which shrink under the influence of heat.
  • the tendency of these types of textile materials to shrink is due not only to the added shrinking fibers but is also due to their structure, i.e., the way in which the individual fibers are incorporated or made into the fabric.
  • the textile materials In order to obtain the required voluminosity and textile feel of the finished goods the textile materials have to be completely shrunk both in width and length. It has been previously suggested to effect this shrinking process by using perforated drums through which a hot treatment medium flows from the outside to the inside. This type of washing device has been found to be very satisfactory indeed. The textile material is thus intensively penetrated by the treatment medium; all fibers come into close contact with the medium and any residual shrinkage of the material is eliminated.
  • German patent application Ser. No. P 20 21 699.3 suggests that the use of a device which ensures the obtainment of an appropriate widthwise material overfeed.
  • This device consists of two rows of pleating disks which are mounted at a certain distance from each other and which serve to bring the material length into wave-like form before entering a treatment bowl. According to the degree of shrinkage, the material may also be fed into the bowl at a speed that is higher than the speed at which the perforated drum transports the material forward. This speed difference can be varied as desired.
  • the textile treating device of the present invention provides a perforated drum and wash bowl having means which supplement orreplace the previously suggested devices for the lengthwise overfeeding of the material to be processed.
  • These means must in any case ensure the uniform wave-like plaiting of the material'onto' the perforated drum as well as the uniform release of the material from the drum; for this purpose the speeds of the feeding and delivering or discharging means must always be the same.
  • this invention contemplates a device for effecting tension-free wet treatment of textile material lengths (e.g., sheets, webs or the like continuous materials) which comprises wash bowl means containing a predetermined level of processing liquor, a rotating perforated drum at least partially immersed in said processing liquor, and guide means for feeding the textile 4 material as wave-like plaits onto the perforated drum and for removing the plaits from the drum, the guide means including heating means for forming the textile material into the wave-like plaits on the perforated drum, the beating means contacting the textile material above the level of liquor in the bowl means, and the drum rotating at a speed which is lower than the speed at which the textile material is fed into the bowl means and onto the drum.
  • wash bowl means containing a predetermined level of processing liquor
  • a rotating perforated drum at least partially immersed in said processing liquor
  • guide means for feeding the textile 4 material as wave-like plaits onto the perforated drum and for removing the plaits from the drum
  • the guide means including heating means for forming the
  • this invention is directed to a device comprising a wash bowl, a rotating perforated drum accomodated in the wash bowl and at least partially immersed in the processing liquor to allow flow of the liquor from the outside to the inside of the drum and means for overfeeding the textile material as wavelike plaits onto the drum, said means including material deflecting devices for feeding and delivering the material to or from the drum, said deflecting devices being installed above the liquor level and parallel to the drum axis and being rotated at the same speed as the drum.
  • the present invention is further characterized in that the first deflecting device at the feed end of the machine is mounted at a certain distance above the liquor level in the bowl; between this deflecting device and the liquor level a beating device is provided which extends over the entige width of the material length hanging vertically down from the first deflecting device and which puts the material in waves or pleats onto the surface of the perforated drum; the speed of the drum being slower than the speed at which the material is fed into the bowl.
  • the beating device comprises a driven roller which is mounted parallel to the axis of the first deflecting device (which is a guide roller) and is equipped with beating elements which extend over the entire width of the roller; the axis of the beating device is preferably shifted sideways from the axis of the first deflecting device, towards the axis of the perforated drum so that the material length is passed between the deflecting device and the beating device.
  • the second deflecting device at the discharge end of the machine is mounted at a certain distance above the liquor level and a nose, i.e., a projection in the form of a bent metal sheet plate, is provided between the deflecting device and the liquor level, close to the surface of the perforated drum.
  • a nose i.e., a projection in the form of a bent metal sheet plate
  • the projection plate is especially advantageous for the above described shrinking bowl because it eliminates any danger of lap formation which could come into being because the discharge speed of the material is higher than the rotating speed of the perforated drum.
  • the device of this invention including the wash bowl which is preferably used for the shrinking and tensionfree processing of textile materials, can be further equipped with a dancing roller which follows the second deflecting device at the discharge end of the bowl and is swivelable or pivotal around a support axis.
  • the dancing roller serves for controlling the rotating speed of the perforated drum and the weight which it exerts upon the material guided around it can be adjusted by means of an assembly of levers.
  • the lever assembly is preferably regulated by a fixed pressure cylinder having a piston therein which is biased by the weight of the roller via a piston rod, as well as by the pressure of the material.
  • the movement of the piston which varies because of the force exerted upon the dancing roller by the material is preferably throttled at the pressure cylinder.
  • This throttling can be especially important or necessary if the individual material waves on the perforated drum are very long and the material length is transferred to the second deflecting device or discharge means at the discharge end of the machine at an intermittent speed. The throttling of the movement of the piston thus eliminates any danger of a constant upward and downward movement of the pivotal dancing roller.
  • a processing bowl of the above described type is conventionally equipped with a valve means through which waste water (i.e., used processing medium) flows off; the volume of the waste water corresponds exactly to the volume of fresh water used as processing medium which is simultaneously supplied to the bowl.
  • This drain valve means which is in most cases designed as a simple overflow is always situated at the material feed end of the textile treating machine while fresh water supply is effected at the discharge end.
  • This arrangement is used in order to permit the application of the well-know counter-current principle.
  • the processing medium is supplied into a multi-bowl washing machine, for example, at the material discharge end, from where it then flows in opposite direction to the material to be treated towards the first bowl of the machine where it finallyflows off as waste water.
  • the projection which contacts the textile material as it is removed from the drum is preferably mounted at a downward angle from a housing wall to the perforated drum so that it can serve as a drain channel for the waste water which is squeezed off the material by the squeezing unit.
  • the bottom of this projection is designed to be liquid-permeable, the waste water which is collected in the nose flows through the perforation holes, directly into the overflow.
  • FIG. 1 shows a device in accordance with this invention including a wash bowl and a subsequent squeezing unit
  • FIG. 2 shows a different embodiment of the wash bowl of the invention.
  • a perforated drum wash bowl comprises a housing 1 which is filled with a washing or shrinkproofing liquor up to a liquor level designated by reference numeral 2.
  • a perforated drum 3 is mounted in the bowl transversely to a passage for the textile material to be treated.
  • the liquor level 4 inside the drum is lower than level 2 outside the drum. This difference of liquor levels is maintained in a conventional manner by pump means installed at one front side of the perforated drum.
  • the processing liquor automatically flows through the textile material 5 to be treated which lies on the perforated drum in the form of plaited waves.
  • the washing unit can also be equipped with an axially fitted pump which produces a suction draft inside the perforated drum 3 and that under certain circumstances the material length 5 can also be put onto the drum 3 without anyfolds or waves.
  • Overfeeding of the textile material 5 onto the perforated drum is essentially effected by setting the speed of the perforated drum lower than the speed at which the material is fed into the bowl and onto the drum.
  • a beating device 7 is installed between a deflecting roller 6 which is mounted at a predetermined distance from the perforated drum 3 and the liquor level 2.
  • the axis of the beating device is parallel to the axes of the perforated drum and the deflector roller and is also shifted or positioned sideways, towards the axis of the drum. Due to its high rotating speed the beating device with the heating elements 8 extending radially outward from its surface effects a rhythmical movement to the material length which hangs down from the deflector roller 6; the formation of uniform waves of material on the drum surface is thus guaranteed.
  • the wash bowl is also equipped or associated with a dancing roller 12 for controlling the running speed of the perforated drum 3.
  • This dancing roller is positioned behind the deflector roller 9 at the discharge end of the machine and is pivotally mounted about an axis 1 1.
  • the roller 12 will move either up or down; this up or downward movement in turn influences the controlling action of a gear (not shown) for controlling the speed of the drum.
  • a gear not shown
  • the counter-weight is replaced by a pneumatic pressure cylinder 13 which in turn may also be replaced by a hydraulic piston-cylinder assembly.
  • the piston rod 14 of the piston assembly is connected to a rocking hinge 11 of the lever assembly for roller 12; whereas the'cylinder 15 is fastened or secured to the squeezing unit 16 which follows the wash bowl 3 in the treating cycle.
  • the piston will move to a certain position in the cylinder 15, and
  • this position is dependent on the weight of the dancing roller 12 and the load which is put upon the dancing roller by the material length 5. If this load is increased, the roller will go up while the piston will go down. Downward movement of the piston, however, will be damped or throttled to a certain degree because of the increase in volume of the air or other fluid in the piston chamber 14. The same applies to the downward movement of the dancing roller 12. If necessary an additional throttling of the movement of the piston may be provided by appropriate means.
  • FIG. 2 shows that the projection 10 is formed of a metal sheet plate 10 which is inclined downwardly from the housing wall towards the perforated drum 3.
  • the waste water which has been squeezed off or out of the textile material by the squeezing unit 16 can'thus be collected in the metal sheet plate 10' and guided towards the bowl.
  • the metal sheet plate 10' can be designed to be liquid-permeable, e.g., perforated, so that the waste water can flow directly into the overflow zone or passage 19 underneath the plate 10'.
  • the volume of waste water returned is determined by the inclined metal sheet plate 21 which is mounted underneath the plate 10' and inclined towards the liquor level in the bowl. This plate 21 also prevents the washing liquor from creeping up at the bottom side of the metal sheet plate 10'.
