Abstract: Paper, board and cardboard are produced from paper stocks which contain tacky impurities by the addition of surfactants and cationic polymers having a charge density of at least 1.5 meq/g (measured at pH 7) and a molar mass M w of the cationic polymers of at least 15,000 and drainage of the paper stocks with fixation of the tacky impurities in the paper produced.

Abstract: Defoamers in which the oil phase of the emulsions contains… (a) a C12- to C26-alcohol, distillation residues obtainable during the production of alcohols with a relatively high carbon number by oxo synthesis or by the Ziegler process and which may also be alkoxylated, and/or… (b) a fatty acid ester of C12- to C22- carboxylic acids with a mono- to tri-hydric C1- to C18-alcohol and optionally… (c) a hydrocarbon having a boiling point above 200 DEG C or fatty acids having 12 to 22 carbon atoms,… comprises 5 to 50% by weight of the make-up of the emulsion and has a mean particle size of less than 25 mu m, and in which 5 to 50 % by weight of the components (a) and (b) of the oil phase are replaced by… (d) at least one compound melting at a temperature above 70 DEG C selected from the group of fatty alcohols having at least 28 C atoms, the esters of a C1- to C22-carboxylic acid with an alcohol having at least 28 C atoms, the polyethylene waxes having a molecular weight of at least 2000, the carnauba waxes, the montanic ester waxes and the montanic acid waxes and their salts.

Abstract: The measuring arrangement consists of successive workstations which comprise a stock of paper samples, a balance, a mechanized moistening means for the sample and a blotting means, likewise mechanized, for the moistened sample. An industrial robot controllable by a program and equipped with a gripping apparatus is provided for carrying out the measurement. This arrangement determines the liquid absorbed by paper using the Cobb method and permits the measuring method to be carried out in a fully mechanized manner.

Abstract: In the present method, single flat products are taken from a stack by means of a vacuum lifting device and are deposited again at a processing station. To ensure that the flat products are taken singly, a sheet of air-impermeable material is inserted between each of these products.
