The invention relates to a method for coating a printed material web (1), in which method, in the order specified, the material web (1) is drawn off a supply roll (2), and, first, a first resin coating is applied onto one side in a first coating apparatus (7), the material web (1) is then guided through a breathing section (9) and is subsequently coated with resin on both sides in a second coating apparatus (8), and the material web (1) is subsequently dried, cooled and wound up or cut to form sheets. The aim of the invention is to improve the method in such a way that it can be carried out in a simple and clean manner and yields an improved quality of the product. This aim is achieved in that the first coating is applied to a printed side of the material web (1) and in that the coated printed side runs contactlessly through the breathing section (9).
The invention relates to a transport device (10) for a beginning or an end of a web, comprising at least one driver (27) for a beginning or an end of a web (1). The transport device (10) is largely guided on a horizontal plane from a front region to a rear region of a system. The transport device (10) is to be improved such that smaller quantities of impregnated decorative paper can be produced with little complexity and minimum waste. For this purpose, the driver (27) comprises a plate-shaped magnet (22) which is guided below the web (1) during the operation of the transport device (10), extends over at least the width of the web (1), and interacts with a magnetizable sheet-metal plate (23) during the operation of the transport device (10), said sheet-metal plate being movable above the web (1) from a rest position into a holding position.

The invention relates to a device for impregnating a paper web (1) running through it with a urea resin which is dissolved in water, and to a corresponding method. Paper webs (1) of this type are used, for example, as furniture foil or floor laminate, wherein exclusively melamine resin is used for adhesive bonding with a substrate in known practice. Devices for impregnation have a large number of deflectors and have a great space requirement. The invention therefore has the aim of providing a device for impregnation which can be produced inexpensively and has a smaller space requirement. This is achieved by the fact that the paper web (1) is guided between the application roller (7) and the dryer (3) in a substantially horizontal plane without deflection and without contact (support).
The invention relates to a method for impregnating and drying a continuous paper web (1) by means of a urea resin dissolved in water, and to a corresponding system. Such paper webs (1) are employed for example as furniture foil or floor laminate, wherein in the known art melamine resin is used exclusively for bonding to a substrate. This is relatively expensive. Therefore the object of the invention is to create a method in which the paper web (1) which is impregnated by means of urea resin can be bonded to the substrate with a high degree of operational reliability. Said object is achieved in that the temperature of the paper web (1) is determined separately in each of the drying zones (3.1, 3.2, 3.3, 3.4), that for each of the drying zones (3.1, 3.2, 3.3, 3.4) an amount and/or a temperature of the circulating air are regulated so that the maximum temperature of the paper web (1) is 99°C, and that exhaust air is extracted from a first one of the drying zones (3.1, 3.2, 3.3, 3.4) and fresh air is supplied to a last one of the drying zones (3.1, 3.2, 3.3, 3.4).

APPARATUS FOR IMPREGNATING A WEB AS IT PASSES THROUGH
The invention relates to an apparatus for impregnating a web as it passes through. In impregnating apparatuses, the web often tears. In the case of the known apparatuses, in normal operation, it is very difficult for the web to be picked up again, and this results in considerable disruption and thus in production losses. The invention avoids these adverse effects in that directing plates are arranged on at least part of the cooling rollers, in that supporting means are arranged in each case between two adjacent cooling rollers, and in that a cutting-action diverter for the web is arranged downstream of one of the final cooling rollers, the cutting-action diverter being suitable for severing the web in a direction perpendicular to the longitudinal extent.

B29B 15/12 - Coating or impregnating of reinforcements of indefinite length
The invention relates to a cross cutter for a paper web. Currently, it is not possible to imprint paper webs continuously with the use of coldset printing inks, and to subsequently cut the web. It is therefore the aim of the invention to configure a cross cutter, which can also be utilized for coldset imprinted paper webs, without having an adverse effect on the print quality, such as by smearing. The aim is achieved in that the speed differences are eliminated between the paper web and the rollers of the cross cutter contacted by the paper web.
