  • Patent number: 10246286
    Abstract: 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.

  • Patent number: 8734615
    Abstract: 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.

  • Patent number: 6962334
    Abstract: A delivery device for stacking cut flat articles such as rotary cross cut sheets has a braking table downstream of a sheet feeder which is provided with two counterrotating disks which are perforated and communicate with suction passages on the table beneath the disks to brake the sheets as they are supplied to a stacker. At the edge of this table, there is a broad slit nozzle directing a sheet of air upwardly onto the underside of the sheets which are delivered to the stacker.

  • Patent number: 6432201
    Abstract: The invention relates to a device for applying a coating substance to a continuous paper web in a process for producing abrasion-resistant laminates for manufacturing decorative paper. The coating substance consists of a viscous mixture of melamine resin and alphacellulose to which particles of corundum are added, and is applied to the visible surface of the paper. The inventive device includes a deflector roll (2) on which the paper web (1) lies in an area in which it loops around; a metering roll (6) which is arranged parallel to the deflector roll (2) and forms the boundary of a gap with the same, and which is driven synchronously or almost synchronously with the deflector roll; a slit nozzle (7) for applying the coating substance either directly to the paper web (1) on the deflector roll (2) or to the metering roll (6); and a doctor blade of a rectangular piece (9) of flexible rubber type material.

  • Patent number: 6343424
    Abstract: An apparatus for drying, cooling, winding up and transverse cooling of a paper web. A lopping device is provided downstream of a conveyor segment lifting the web over the winder or sheet cutter, whichever is proximal to the cooler, the paper web then reaching a bifurcation from then which it may be directed to engagement with the mandrel in a winding readiness position of the coiler or to a conveyor segment for the transverse cutter.

  • Patent number: 6231670
    Abstract: A paper web impregnated with a liquid resin and following impregnation is coated with an abrasive particle containing coating mass or composition and then dried before a liquid resin is applied which does not contain the abrasive particles. The web is then finally dried and the resulting paper is particularly suitable as a cover sheet in the hot pressing of laminates since it minimizes wear of the laminate press.
