Definitions

  • the apparatus has at least one rotatable roller below the level of a liquid in a tank and over which the strip of material is to be passed. Means are provided for directing into the wedge-shaped opening formed between the surface of the roller and the incoming strip of material jets of liquid which are distributed along the roller.
  • the rol- Iers are either freely rotatable,in which case the strip material is pulled over or around the rollers by means of a transport device, or the rollers are motor driven.
  • the film is in direct contact with the rollers during its travel through the apparatus. This often damages the strip material, particularly its surface.
  • the use of special roller surfaces, particularly soft surfaces, does not, always provide an effective remedy.
  • a device having at least one rotatable roller which is arranged in a tank for liquid below the level of liquid and over which strip material is to be passed and means for directing into the wedgeshaped space formed between the I surface of the roller and the incoming web of material, jets of liquid which are distributed along the roller.
  • FIG. 1 illustrates apparatus for handling strip material
  • FIG. 2 illustrates an alternative form of apparatus to that shown in FIG. 1.
  • the apparatus illustrated are mounted in tanks which contain liquid, only the bottom B of the tank being shown together with the level of liquid N.
  • Rollers around which the strip is passed and indicated by the reference lu and the guide rollers over which the strip is passed and indicated by the reference If in FIG. 2 are freely rotatable.
  • the distributors are fed through pipes'8.
  • the jet apertures 2 are so disposed in relation to the rollers and are directed generally peripherally of the roller la.
  • the .axis 24 of each aperture is at an acute angle to a tangent! to. the surface of the rollers la and If at the point r. where the axis intersects the surfaces of the rollers. From this point the pressure jets S are directed
  • baffles 5 disposed adjacent the jets to provide narrow passageways between the baffles and the surfaces of the rollers.
  • the distance between the pressure jet apertures 2 and the roller surface amounts only to a fraction of the diameter of the roller, preferably about one-tenth thereof.
  • the jet is preferably adjusted so that the peripheral speed of the rollers is higher than the speed at which the strip material is transported over the rollers.
  • the jet liquid can be selected so that chemical and/or physical treatment effects are simultaneously achieved on the strip material.
  • the same liquid as is already contained in the tank (level N) is used.
  • the rollers may be mounted between two plates 6, of which only one (the rear plate) is visible in the drawing. These two plates are fastened to the bottom B of the tank.
  • the strip of material 4a4b is moved over the guide rollers l f and rollers In by means of a motor driven transport device.
  • This transport device may, for example, comprise a pair of motor driven traction chains on which the strip of material is connected by clips or the like at one or more points.
  • Such transport devices are generally known. In order not to impair generally peripherally along the. roller into the wedge-shaped v the clarity of the drawings, they have therefore not been illustrated in detail.
  • a sprocket wheel 7 forming part of the transport device is shown, mounted on one end of the roller la and a similar sprocket wheel (not shown) is mounted at the other end.
  • These two sprocket wheels and the roller lu are freely rotatable independently of one another. Of the other pairs of sprocket wheels (not illustrated) at least one is adapted to be driven by a motor.
  • a number of freely rotatable rollers lf, lu are disposed in a row.
  • the strip of material is passed around the lowermost roller lu and runs past both sides of the guide rollers If in opposite directions.
  • roller If (guide roller) which is in the middle in the drawing, two rows of pressure jet apertures 2 are situated one on each side of the intermediate roller If approximately diametrically opposite one another and are coupled to a common distributor via pipes 8.
  • the liquid cushion consequently produced between the strip and the roller once again prevents any contact between strip and roller and improves the physical or chemical action of the liquid on the strip.
  • a device for the guiding of strip material which is kept out of contact with the device, said device comprising a tank adapted to contain liquid to a predetermined level therein, at least one freely rotatable roller positioned in said tank below said level of the liquid and over which strip material is to be passed, and a fluid distributor extending parallel to said roller having a plurality of apertures for forming jets of liquid, each of said apertures being directed in a direction generally peripherally of the roller and at an acute angle to a tangent to the surface of said roller at the point of intersection between the axis of the aperture and the surface of the roller, whereby the jets of liquid are directed generally peripherally along the roller into the wedge-shaped space formed between the surface of the roller and the strip material at an acute angle relative to the direction of movement of the strip material to prevent contact between the strip material and the roller and to cause the roller to rotate.
  • a device as claimed in claim I in which the apertures of the distributor are spaced from the nearest point on the periphery of said roller a distance of about one-tenth the diameter of the roller. 3. A device as claimed in claim 1, further comprising a baffle adjacent to said apertures and to the surface of said roller and spaced from said roller to define a narrow passageway between the baffle and the roller into which said jets of liquid are directed.
  • a device for the guiding and turning of strip material which is kept out of contact with the device, said device comprising a tank adapted to contain liquid to a predetermined level therein, a row of freely rotatable rollers positioned in said tank below said level of the liquid, the strip material being passed around the end roller in the row and-passed along both sides of the row in opposite directions, fluid distributors in said row at least at one roller intermediate the other rollers and disposed parallel to said rollers diametrically opposite one another on either side of the intermediate roller, said distributors having a plurality of apertures for forming jets of liquid, said apertures being provided diametrically opposite one another on either side of the roller,
  • each of said apertures being disposed in relation to the roller and directed in a direction generally peripherally of the roller and at an acute angle to a tangent to the surface of said roller at the point of intersection between the axis of the aperture and the surface of the roller, whereby the jets of liquid are directed generally peripherally along the roller into the ,wedge' shaped spaced formed between the surface of said roller and the strip material at an acute angle relative to the direction of movement of the strip material to prevent contact between the roller and the strip material and to cause the roller to rotate.
  • rollers are caused by the jets of liquid to rotate at a peripheral speed in excess of the speed of movement of the strip material along said roller.
  • a device for the guiding of strip material which is kept out of contact with the device, said device comprising a tank adapted to contain liquid to a predetermined level therein, a row of freelyrotatable rollers positioned in said tank below said level of the liquid, strip material being passed along both sides of therow in opposite directions, fluid distributors in said row at least at one roller intermediate the other rollers and disposed parallel to said rollers diametrically opposite one another on either side of the intermediate roller, said distributors having a plurality of apertures for forming jets of liquid, said apertures being provided diametrically opposite one another on either side of the roller, each of said apertures being disposed in relation to the roller and directed in a direction generally peripherally of the roller and at an acute angle to a tangent to the surface of said roller at the point of intersection between the axis of the aperture and the surface of the roller, whereby the jets of liquid are directed generally peripherally along the roller into the r wedge-shaped spaces formed between the surface of said roller and
