Definitions
- the invention relates to a calender for calendering of paper as a web of selectable width passes through at least one nip, which by a heated hard roller and one with an elastic Covered soft roller is limited. It is not only the absolute temperature is decisive. Much more may also have a predetermined temperature difference between the one covered by the train and the uncovered Section must not be exceeded.
- the invention is therefore based on the object Way to show how to easily at effective protection with different web widths of the cover against overheating.
- this object is achieved by rotating insulating tapes that reduce heat transfer, the at least in the nip that of the web cover the free edge areas of the cover.
- insulation tapes wear in two ways to ensure that the edge areas free of the paper web the elastic cover must not be overheated. To the One becomes heat transfer due to its insulating effect from the surface of the hard roller to the Cover reduced. On the other hand, the insulation tape form a support that is too close an approximation the surface of the hard roller to the cover or even prevent touching the cover. Simulate basically these insulation tapes the missing paper web.
- Endless insulation tapes are particularly recommended passed over at least one pulley and through one Clamping device are clamped. These insulation tapes only wrap the associated roller over part of their scope and are then on one by one or several deflection rollers guided certain path. Here can heat through the surrounding air or through a cooling device can be removed. The jig ensures that the insulation tapes are smooth of the associated roller. As a result the insulation tapes are driven by the wrapped roller.
- the Insulation tapes the hard roller. This is especially true if the hard roller due to the oxbow effect one greater width of its cylindrical part than that Width of the cylindrical part of the cover. This results in a particularly good support.
- the insulating tapes expediently have a smaller one Thicker than the paper of the web. This ensures that the insulation tapes are not the compressive stress change inadmissible at the edges of the paper web.
- the insulation tapes have a lower resistance to deformation than have the paper of the web.
- Such an insulation tape is easier to compress than paper and therefore has no negative impact on the satin Paper web edges.
- the insulating tapes advantageously consist of fiber-reinforced Plastic. Depending on what temperatures accept the hard roller on its surface the material of the insulation tapes should be selected that there is no overheating.
- the width of the insulation tapes is chosen is that they don't have the cylindrical part of the hard Protrude from the roller or the cover of the soft roller. With such guidance of the insulation tapes there is no risk of the tape running.
- a detection device is recommended the the position of the web edges to determine the width of the insulation tapes and their positioning in the nip is detected. This makes it easier the use of insulation tapes.
- the one roller is a deflection adjusting roller with particular advantage with zone control and is the Pressure in the zones assigned to the insulation tapes reduced compared to the other zones.
- This leaves the desired compressive stress profile with high accuracy adjust, even if different widths Tracks are processed.
- the two-roll calender illustrated in FIGS. 1 to 3 has a hard roller 2 and a soft roller 3 on.
- the hard roller has a cylindrical part 4, which is approximately uniform over its entire width A. is heated, for example with heating oil, through the axially parallel Drilling near the surface by an electric heater or the like.
- the soft Roller 3 carries a cover 5, the cylindrical Part 6 has a width B, in this embodiment is smaller than the width A of the cylindrical Part 4 of the hard roller 2, but also have other values can.
- the rollers 2 and 3 form a nip 7, in which a sheet 8 of paper with maximum width C is satined. Remain on both sides of the web 8 Areas 9 of the cover 5 of such a small width a, for example 10 or 15 mm or less that by the web 8 at a distance from the hot surface of the hard roller 2 are held and not damaged can.
- the tapes are preferably made of a fiber reinforced Plastic that has a higher temperature resistance Has.
- the 2 also shows two recognition devices 16 and 17, which capture the web edges.
- Dependent on the width B of the insulating tapes 11 is determined therefrom and also determines how far the insulation tapes have to be pushed axially in order to to be optimally effective.
- the detection devices can be formed, for example, by photocells. As soon as the edges of the paper web 8a have been detected, you can axially the tapes 11 from the outside into the nip 7 drive in. Then the nip can closed and operations begin. Should the web 8a during production over an allowable The insulation tapes would have to change the tolerance range be repositioned accordingly.
- Fig. 3 shows that the insulating tape 11 is an endless insulating tape is that the hard roller 2 over more than wraps half of its circumference and over a deflection roller 13 is conducted by means of a Arrows indicated tensioning device 14 can be tensioned can.
- tensioning device 14 can be tensioned can.
- the insulating tape 11 from the rotating hard roller 2 driven. This means, that heated on the hard roller during the plant Parts of the insulation tape temporarily free Exposed to the atmosphere and allowed to cool down there, if necessary with the help of a cooling device.
- FIG. 4 An alternative is illustrated in FIG. 4.
- the insulation tape 11a wraps around the elastic cover 5 of the soft Roller 3 and is by a deflecting roller 13a by a tensioning device indicated by the arrows 14a is loaded, pressed against the cover 5.
- the insulating tape 11a by the rotating soft roller 3 driven.
- Fig. 2 is also shown schematically that the soft roller 3 is a deflection adjusting roller which has a series of zones 15, each of which pressure medium is supplied at a predetermined pressure.
- the zones are, for example, each one hydrostatic Support element or several such support elements educated. Those located in the area of the insulation tapes 11 Zones 15 'are at a lower pressure acted upon as the remaining support elements.
