Definitions

the invention relates to a device for applying microcreping to a paper web according to the preamble of claim 1.
Paper webs treated in this way are often used for bag production.
the aim of the invention is to avoid these disadvantages and to propose a device of the type mentioned at the outset with which the production of paper webs having a high slip resistance and a high dust absorption capacity can be produced.
the proposed elevations of the side of the printing blanket facing the cylinder not only cause the paper web to crepe, but further deformations which also extend in the longitudinal direction of the paper web are forced when the paper web passes through the nip between the cylinder and the printing blanket.
the features of claim 2 have the advantage that the paper web is very finely structured.
the paper web is creped in its longitudinal and transverse directions, as a result of which such a paper web has a particularly high dust absorption capacity.
a paper web treated using such a printing blanket is distinguished by a particularly high slip resistance.
a device for applying a microcreping essentially has a heated and driven cylinder 10 and a driven circumferential rubber blanket 11, which runs over drive and guide rollers 12 and is subjected to a certain tension by means of a tension roller 13.
a press bar 14 is provided, which is movable radially to the cylinder 10, which has a polished surface.
the pressure beam 15 is directly upstream of a spray tube 16 in the direction of travel of the rubber blanket 11, with which a Wassser-Si-silicone mixture is sprayed onto the rubber blanket 11 in order to reduce the friction between the pressure beam 14 and the rubber blanket 11.
the rubber blanket 11 describes a convex curved path in the region of the press beam, which is immediately followed by a concave curved path region of the rubber blanket 11, which lies against the cylinder 10.
the paper web to be creped runs between the rubber blanket 11 and the cylinder 10.
the paper web 17 passes the pressing point between the heated cylinder 10 and the surrounding rubber blanket 11.
the rubber blanket 11 is an endless belt with a thickness of approximately 5 mm and approximately greater width than the working width of the incoming paper from a particularly hard-wearing rubber quality with a hardness of approx. 50 durometer. It is provided with a continuous reinforcement insert 18 to reduce the stretching of the fabric.
the neutral axis of the cloth also moves inwards. If the circumferential rubber blanket 11 now passes the narrowed point between the cylinder 10 and the pressed pressure bar 14 whose distance is less than the blanket thickness, the outer part of the rubber blanket 11 is accelerated, while the inner part continues to run at the somewhat slower blanket speed. The process could be compared to the flow of a liquid through a Venturi nozzle.
Section 1 is flat and runs at a speed of (v - ⁇ v), ie slower than the paper web 17 before contact with the rubber blanket 11 (section 2) is deformed by the curvature of the press beam 14, the speed is unchanged on the inside, on the outside Extent, however, has already almost accelerated to paper speed v.
the following constriction accelerates the cloth 11 further on the outside, so that it has already reached the speed v of the paper web 17 or the cylinder circumference at the beginning of section 3, so that the paper web 17 can run in freely between the cloth 11 and cylinder 10 and is guided taut the pinch point happens.
the squeezed rubber blanket 11 begins to relax, ie to shorten, and adapts to the original speed of (v - ⁇ v) again.
the paper 17 is compressed by the relaxing rubber blanket 11.
the rubber blanket 11 must now follow the opposite curvature of the cylinder (section 4), which causes a further compression of the paper web 17.
the paper is subjected to a high longitudinal force due to the friction effect of the rubber blanket 11, but it slides on the polished cylinder surface, on which a vapor film is formed on top of it.
the shear forces act as compression forces, the fibers are pushed closer together and even partially superimposed and curved. Since the rubber blanket 11, which is under pressure from the press beam 14 and under tensile forces from the fabric tension, simultaneously exerts large radial forces on the paper web 17, it has no freedom of movement in this direction.
the paper web 17 therefore retains a largely smooth surface which only has a micro-crepe.
the side of the rubber blanket 11 facing the paper to be treated has grooves 19 which extend parallel to one another and extend in the longitudinal direction of the rubber blanket 11.
the side edge region 20 of the rubber blanket is free of grooves 19.
