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.
PATENTED JUL20 m1 SHEET 1 OF 2 FIG] ATTORNEYS PATENTEDJUL20I97I SHEET 2 OF 2 INVENTORS JOSEPH BECHEIRAZ ULRICH FRAUCHIGER ATTORNEYS STRIP HANDLING APPARATUS This invention relates to strip handling apparatus 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 arranged to travel.
In apparatus such as that used for film processing, 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.
In some previous apparatus of this type, 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.
It has therefore been proposed to produce a gas or liquid cushion between fixed return or guide elements and the strip material. Fixed elements having pressure jet apertures have been used but it has been found that it is very difficult to obtain a stable operating state which reliably prevents contact between the surface of the element and the strip material.
It has now been found that this problem can be solved in a very simple manner by using a member having apertures from which jets of liquid emerge --into the wedge-shaped space between the surface of the roller and the incoming strip of material, the apertures being arranged to distribute the jets of liquid along the surface of the roller.
In accordance with the invention, therefore, we provide in a strip handling apparatus, 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.
If fixed rollers are used the desired effect of forming a continuous liquid cushion cannot be achieved or can be achieved only to an insufficient extent. This is probably due to the fact that whereas the layer of liquid which normally rotates with a rotating roller is given impetus by the jets of liquid acting in the direction of rotation of the roller to such an extent that contact between the strip and the roller surface is avoided,
such a layer is not given sufficient impetus when the roller is fixed thereby making separation of the strip from the roller surface unreliable. In addition, a jet acting in the direction of rotation of the rollers produces a driving effect and also compensates for the resistance to movement of the strip material.
Two embodiments of the invention will now be described in greater detail with reference to the accompanying drawings, in which:
FIG. 1 illustrates apparatus for handling strip material, and
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. Parallel to each return roller la and to each guide roller If there is disposed at least-one distributor 3 having jet apertures 2 directed towards the surface of the rollers. 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 The effect produced by the jets may be further enhanced by 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. With the usual,
dimensions employed for the rollers in film processing apparatus this distance is between about I and 10 mm.
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. In particular, the same liquid as is already contained in the tank (level N) is used.
As indicated in FIG. 1, 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. In FIG. I 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.
In the embodiment illustrated in FIG. 2, 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. At the 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.
