Definitions
- the invention relates to a device according to the preamble of patent claim 1.
- a device is known from German Offenlegungsschrift 4100771.
- coating compound is applied to a belt that wraps around it in a nip that is formed on a mating roller guiding the web transferred to the same.
- the support roller can have a relatively small diameter in order to guide the tape with or with a relatively small radius of curvature at or through the application gap.
- Certain support devices for the support roller are of course necessary in order to be able to set the coating gap relatively precisely. It should have a width between 0.1 and 1.5 mm.
- the object of the invention is to provide suitable support devices for the support roller.
- Figure 3 is a view of a second basic embodiment of the invention.
- the paper web B is guided by a support roller 5 in the area of the application device.
- the application device has a flexible band 2 made of plastic or rubber or rubber-like plastic, which is guided over two guide rollers 4 and 4 ', which are arranged in a position so that their highest point is above the level of a tub 12 which receives the coating material.
- the belt 2 is also guided over a support roller 6, where the coating gap 7 is formed to the counter roll or running web.
- another roller 10 is used with a relatively large diameter in relation to the support roller 6, which is located in the area of the diameter of the guide rollers 4 and 4 '. At least one of the guide rollers 4 is driven and serves to drive the belt 2 at the corresponding speed that is to be present in the coating gap.
- the web speed should preferably be over 1000 m / min.
- the speed of the belt 2 should be adjustable and should be between 5 and 100, preferably between 5 and 30% of the web speed with the same direction of movement or between 5 and 30% of the web speed with the opposite direction of movement.
- the further roller 10 supporting the support roller 6 should also be driven at one of the peripheral speeds Support roller corresponding peripheral speed (that is, with the same diameter of the large rollers wrapped by the belt 2 with the number of drives of the drive roller 4).
- the further support roller 10 is supported by the guide rollers 4 and 4 '.
- the further support roller 10 can of course be given a relatively small diameter, since it is in turn supported by the guide rollers. If, for example, according to FIG. 1, the additional support roller had a diameter of between 300 and 500 mm, it can now be chosen to be correspondingly smaller.
- the diameter of the support roller 6 can be between 10 and 150 mm, preferably between 20 and 100 mm. In the case of FIG.
- the additional support roller 10 can be arranged somewhat offset in the web running direction with respect to the axes of rotation of the counter roller 5, the support roller 6 and the two guide rollers, in order thus to provide a counterforce in the horizontal direction to the hydrodynamic force when the belt is fed in and to have the web in the coating gap.
- sealing devices 21 are provided, which are located in the region of the edges of the hose 2.
- These sealing devices consist, for example, of a carrier 22 which is fastened to the end walls of the tub 12 via a holder 24. They have 2 sealing strips 23 at their edges opposite the guide rollers and the hose. These can be made of a very lubricious plastic, such as Teflon. Since it is to be expected that absolute tightness cannot be achieved, the space between the sealing devices can 21, the guide rollers 4 and 4 'and the lower part of the hose 2 may be filled with water. It can be achieved that only a very small amount of water leaks, so that the consistency and composition of the coating slip is not significantly affected.
- FIG 3 there is a single drive roller 4, over which and the support roller 6, the flexible belt 2 'is guided.
- the tub receiving the coating composition, in which the drive roller 4 practically wades, and the counter-roller, which guides the web, are not shown.
- the support roller 6 is supported by further rollers 9, 9 'of relatively small diameter on the guide roller 4.
- the rollers of relatively small diameter are supported laterally by side supports 13, 13 'via strips 14, 14' and pressure hoses 15, 15 '.
- the two small support rollers have a diameter of between 20 and 40 mm. They are of course also preferably to be driven at the peripheral speed of the support roller 6, just like the guide roller 4. It can be achieved by these small rollers that the support roller 6 is given a certain curvature of its axis of rotation, which can also be zero.
- FIG. 4 shows a variant of this embodiment, in which the axis of symmetry drawn through the axes of rotation of support roller 6 and drive roller 4 and between the two small rollers forms a certain angle with respect to the vertical, so that the excess coating slip easily passes into the tub 12 'at the application gap. can expire.
- FIG. 5 it is formed by the axes of rotation of Support roller 6 and drive roller 4 drawn axis of symmetry an angle between 15 and 45 ° to the tangent drawn in the coating gap to the counter roller 5.
- pre-dewatering and rubbing of the coating slip (ink) can advantageously be achieved, particularly for gravure printing papers.
- the small pair of rollers can also be omitted in the variants according to FIGS. 3-5 and the supporting roller 6 e.g. than the known spreader roller according to German patent 1425060 can train.
- This roller can have a plastic or rubber jacket.
- the hose 2 may preferably consist of several layers, the inside being smooth and firm, e.g. is made of a plastic or stainless steel and has a felt-like fabric on the outside. This allows the coating slip to be guided to the coating gap better and more uniformly.
