Example 2

Es wird folgende Kunststofflösung aus einem •arboxylgruppenhaltigen Copolymerisat hergestellt: 8 kg eines Copolymerisate aus 35 % Methacrylsäure ind 65 % Methacrylsäuremethylester werden in einem .ösungsmittelgemisch aus 61,5 kg Äthylglycol und !0,5 kg Tetralin aufgelöst. In diese Lösung rührt nan noch 35,7 kg einer 70%igen Lösung von PoIy-/inylmethyläther (K-Wert: 40) in Toluol ein. Diese Cunststofflösung wird mittels einer Rakel auf die lückseite einer Cambricpapierbahn aufgetragen, wojei der Kunststoffauftrag 12 g/qm, bezogen auf Trockensubstanz, beträgt.

Stir into this solution nan still 35.7 kg of a 70% solution of poly- / inylmethylether (K value: 40) in toluene. This plastic solution is applied to the applied to the back of a Cambric paper web, wojei the amount of plastic applied is 12 g / m², based on the dry substance. The solvent will evaporated by drying in a drying tunnel.

Example 3

Der Kunststoff- -uftrag beträgt 8 g/qm, bezogen auf Trockensubstanz. )as Lösungsmittel wird durch Trocknen im Trockenianal verdampft.A plastic solution produced according to Example 2 has been, with HiWe a doctor blade on a plastic film made of polyvinyl chloride, which is a ) icke of 40μ has, applied. The plastic application is 8 g / m², based on dry substance. ) The solvent is removed by drying in a drying chamber evaporates.

Example 4

Es wird eine Lösung von 20 kg Polyacrylsäure in einer Mischung aus 40 kg Äthanol und 40 kg Methanol hergestellt. Diese Lösung wird auf die Rückseite einer Papierbahn aus Glacepapier in einer Stärke von 12 g/qm, bezogen auf Trockensubstanz, aufgetragen. Das Lösungsmittel wird durch Trocknen im Trocken kanal verdampft.It is a solution of 20 kg of polyacrylic acid in a mixture of 40 kg of ethanol and 40 kg of methanol manufactured. This solution is applied to the back of a paper web made of ice-cream paper in a thickness of 12 g / qm, based on dry substance, applied. The solvent is made by drying evaporated in the drying tunnel.

Example 5

Es wird eine Lösung eines Copolymerisate aus Maleinsäureanhydrid, Vinylacetat und Vinylchlorid in einer Estermischung aus gleichen Teilen Äthylacetat und Butylacetat hergestellt. Die Lösung wird mittels einer Rakel auf die Rückseite einer Papierbahn aus Hochglanzglacopapier aufgetragen. Der Kunststoffauftrag beträgt 10 g/qin, bezogen auf Trockensubstanz. Das Lösungsmittel wird durch TrocknenIt becomes a solution of a copolymer of maleic anhydride, vinyl acetate and vinyl chloride produced in an ester mixture from equal parts of ethyl acetate and butyl acetate. The solution will be applied by means of a doctor blade to the back of a paper web made of glossy glass paper. The plastic application is 10 g / qin, based on dry matter. The solvent is made by drying

Example 6

Eine Lösung aus 15 kg eines carboxylierten Methacrylsäureesters in 35 kg Glykolsäurebutylester und as 7 kg Tetralin, wird auf die Rückseite einer Papierbahn aus Velourspapier aufgetragen. Der Kunststoffauftrag beträgt 15 g/qm, bezogen auf Trockensubstanz. Das Lösungsmittel wird durch Trocknen in einem Trockenkanal verdampft.A solution of 15 kg of a carboxylated methacrylic acid ester in 35 kg of butyl glycolate and 7 kg of tetralin as is on the back of a paper web Applied from velor paper. The amount of plastic applied is 15 g / m², based on the dry substance. The solvent is evaporated by drying in a drying tunnel.

B. polyacrylic acid esters, poly-caused by the impact of the moisture of the methacrylic acid esters, polyvinyl chloride, polyvinylidene used adhesive, have a strong tendency to roll, so that chloride, polyvinyl acetate, polyvinyl alkyl ethers, polycycles are often difficult to stick to the vinyl acetate, styrene, etc. The only condition is that that Have the object applied. Another disadvantage of copolymers or polymer mixtures in water, which is often observed, is that the glue is swellable. The arrangement of the individual layers even penetrates through the paper, so that the drawing shows, in the enlarged top side of the label or the blank, on a larger scale A, a cross-section through a label made of natural paper that has been prepared in advance after drying that make the label or the blank unsightly 35 and B a cross-section through a device according to the invention. It also often happens that the pre-prepared label from a surface glue is repelled from the label paper, so that noble paper is displayed,
