A paper, board or non-woven product containing a fiber layer containing cellulosic fibers, plant fibers or other material suitable for making a paper, board or non-woven product. One surface of the fiber layer is treated with pigment particles. The web is treated with microscopic particles whose average size is so small as to permit the particles to adhere to each other by van der Waals forces.

Paper having a cellulosic fiber layer treated with elementary particles

Apparatus for forming a paper or board web made from fibers in which the web is treated with calcium hydroxide and then with carbon dioxide gas so as to form calcium carbonate.

Apparatus for making a web of paper or board containing calcium carbonate

Method and assembly for forming a paper or board web and a product made using the method. According to the method, the web ( ) is made from fibers and then the web ( ) is treated with pigment particles. The web is treated with microscopic pigment particles whose average size is so small as to permit the particles to adhere to each other by van der Waals forces. The particles are transferred to the web and adhered thereto advantageously using an ion-blast technique.

Method for making paper, assembly for implementing the method and paper product produced by the method

A method for calendering a paper web, including the steps of passing the paper web through a calendering nip having a profile formed from a pair of calendering rolls, wherein at least one of the pair of calendering rolls includes a soft exterior face at least in the region of the nip, regulating the profile of the calendering nip to compensate for flaws in the paper web passing through the calendering nip including varying the properties of the soft exterior face locally in a direction transverse to the direction of the passing paper web concurrently with the passing step.

Method for calendering a paper web and a calendar that makes use of the

A method and apparatus for heating a paper web in a calender in which the paper web is heated before it is passed into a calendering nip of the calender. The paper web is heated by a source of radiation and the heat radiation coming from the source of radiation is condensed and guided by a reflector face or an equivalent optical device onto the paper web and/or onto a face of one of the rolls in the calendering nip substantially directly before the calendering nip.
