Definitions
- the invention relates to a pressure roller or rotating pressure belt for forming a winding nip with a spool in a winding machine for winding a material web, in particular paper or board web. It further relates to a winding machine with such a pressure roller or circulating pressure belt.
- Pressure rollers and winding machines of the type mentioned are known. It has also been attempted to prevent the wrapping of air during winding of the web by appropriate pressing of the pressure roller, an air squeezing or the like to the spool. Grooved pressure rolls have also been used to prevent the material web from floating.
- the invention has for its object to provide an improved pressure roller or - band and an improved winding machine of the type mentioned, in which it is ensured that wrapped air is removed as quickly as possible.
- the object is achieved according to the invention in that the roller or belt surface adjoining the winding gap has spirally running, at least catchy grooves, each having a depth in the range from approximately 0.4 mm to approximately 1, 5 mm and each have a width, preferably maximum width, in the range of about 35 to about 60 mm.
- the air enclosed during winding of the material web is removed quickly and reliably again.
- the material web dips into the grooves and forms laterally limited air chambers for the wrapped air. Due to the spiral shape of the grooves, the air is pumped outwards.
- the grooves each have a depth in the range of 0.8 mm.
- the grooves each have a width, preferably maximum width, in the range of 40 mm.
- the spiral grooves extend in the direction of the roll axis or, viewed transversely to the strip running direction, outward from a central roll or strip area.
- the grooving is preferably carried out at least partially catchy.
- this scoring is carried out at least partially more frequently. It is advantageous if the various courses are distributed uniformly over the roll circumference or adjacent to the winding nip contact surface of the band.
- the grooving is expediently carried out 1 to 5 courses.
- it may in particular be at least partially 2-pass, at least partially 3-pass or at least partially at least 4-pass. Due to the multiple passes, more air can be discharged.
- the grooves according to an advantageous embodiment in particular from radially inward to outward at least partially have a concave cross-sectional shape.
- these grooves may, in particular from radially inward to outward, at least partially also have a lenticular cross-sectional shape.
- Conceivable is advantageously also a rectangular or trapezoidal cross-sectional shape.
- the groove pitch is at least partially in the range of about 300 mm to about 1500 mm, and preferably in the range of 600 mm.
- a web In the area of the roll center, a web can remain in the range from 0 mm to about 200 mm.
- the number of flights is adapted to the pitch so that a web remains in the range between about 100 mm and about 400 mm and preferably in the range of 200 mm.
- the pressure roller preferably has a diameter of> 700 mm and preferably> 1000 mm.
- the creasing can be provided directly on the roller body or, in particular, on a belt or the like surrounding the roller.
- the roller or the belt is driven.
- the relative speed to the drum can be controlled, whereby the Wasseraustreib bin can be further optimized.
- the slip can be controlled accordingly.
- the contact surface of the pressure roller or of the circulating belt or of a belt surrounding the roller to the drum is provided with a groove of a specific geometry. It is important that the scoring is substantially spiraling from a central region starting outwards. The scoring comes into contact with the surface of the spool, which is soft due to the wrapped air. The material web dips something into the grooves and forms a laterally limited air chamber for the wrapped air. Due to the spiral shape, it is pumped outwards.
- the effectiveness depends on the geometry of the grooves.
- the scoring is preferably more continuous, i. e.g. 2 or 3-speed or at least 4-speed, which allows more air to be discharged.
- the shape of the grooves may in particular be concave, lenticular or even rectangular or trapezoidal, etc.
- the pressure roller or carrier drum or the rotating pressure belt is driven in order to control the relative speed to the drum can.
- the Wasseraustreib bin can be further optimized, in particular, the slip can be controlled accordingly. Due to the fact that the contact surface due to the groove to the drum is reduced, it is advantageous if the nip force is controlled and / or regulated, since fluctuations greatly affect the surface pressure and thus can produce markings in the web. By the invention, it is possible to avoid blistering or to establish a stable bubble.
- the speed can be adjusted to the pitch so that a ridge remains in the range of about 100 to about 400 mm, preferably in the range of 200 mm.
- the winding machine according to the invention is characterized in that it comprises a pressure roller according to the invention or a circumferential pressure belt according to the invention, which forms a winding nip with a spool through which a material web, in particular paper or board web is passed to then wound onto the spool to become.
- the pressure roller according to the invention, the pressure belt according to the invention or the winding machine according to the invention can be used with particular advantage for winding a material web, in particular paper or board web whose air permeability ⁇ 50 ml / min according to Bendtsen according to DIN 53120-1.
- 1 is a schematic representation of an exemplary embodiment of a winding machine with a tambourizing the associated pressure roller
- 2 is a schematic representation of an exemplary embodiment of a pressure roller with catchy grooves
- Fig. 3 is a schematic representation of an exemplary embodiment of a pressure roller with 3-course grooves
- FIGS. 4 to 6 are exemplary groove cross-sectional shapes.
- Fig. 1 shows a schematic representation of an exemplary embodiment of a winding machine 10 with a pressure roller 12 which forms a winding nip 16 with a spool 14, through which a web of material 17 is passed, to be subsequently wound onto the spool 14.
- the material web 17 may float on the pressure roller 12 as well as air inclusions during winding on the spool 14, as indicated in FIG. 1.
- Fig. 2 shows in the right part in a schematic representation of an exemplary embodiment of a pressure roller 12 according to the invention with catchy grooves 18, as can be used for example in the winding machine shown in FIG.
- the roll surface 20 adjoining the winding nip 14 has spirally extending, here for example catchy grooves 18, each having a depth t in the range of about 0.4 mm to about 1, 5 mm and each having a width b, preferably maximum width b, in the range of about 35 to about 60 mm.
- these grooves 18 have a depth in the range of 0.8 mm.
- Fig. 2 shows a cross section along the line A-A. As can be seen from this left in Fig. 2 representation of a respective groove, the groove edges are broken in the present case.
- the groove pitch rs may be at least partially in the range of about 300 mm to about 1500 mm, in the present case, for example, in the range of about 600 mm.
- the groove pitch rs is also in the present case, for example, again about 600 mm.
- an overlap of in particular 0 to 100 mm, preferably 0 mm can be made.
- the number of flights can be adapted to the pitch so that a web 22 in the range of in particular from about 100 to about 400 mm, preferably in the range of 200 mm remains.
- FIGS. 4 to 6 show exemplary cross-sectional shapes of the grooves 18.
- the respective groove 18 at least partially, for example, a rectangular (see Fig .. 4), have a trapezoidal (see Fig. 5) or any other cross-sectional shape, for example, as shown in FIG the two lateral edges of the groove 18 are shaped differently. In the present case, the right edge is rounded throughout, while the left edge is angled. LIST OF REFERENCE NUMBERS
