Abstract: The present invention relates to a roll or a wheel, wherein the roll or the wheel is provided with (i) a stiff, essentially cylindrical roll core or wheel core that is provided at its lateral surface with a surface that is subject to wear; (ii) a data logger, that is positioned on said roll core or said wheel core of said surface, provided with at least (a) a sensor for monitoring information relating to the operation of said roll or said wheel or said surface; (b) a processor for processing said information; (c) tangible, non-volatile memory for storing said information; (d) a wireless network interface for sending and receiving data comprising said information; (e) program data stored in said memory for controlling said processor; (g) a battery or equivalent energy source for feeding (a) and/or (b) and/or (c) and/or (d); wherein said data comprise roll or wheel related data, such as e.g. a unique serial number and/or dimensions for identification of the roll or the wheel.

Abstract: In a first aspect, the invention relates to a roller core (2) with a tubular supporting wall (4) which extends conically widening (19). The roller core is adapted to receive an interchangeable roller sleeve (3) that can be stretched around it under air pressure. In particular, the roller core comprises an internal air distribution chamber (17) which is limited annularly by an internal surface of the supporting wall, and which is limited via an internal wall portion (27, 27?) to a smaller partial volume of the internal roller volume. In further aspects, the invention relates to an applicator roller (1), a method for mounting and dismounting roller sleeves, and a method for manufacturing roller cores.

Abstract: A covering panel has a support plate, made from synthetic plastic material, with a flat and even top surface, a bottom face and pairs of opposite sides provided with complementary profile edges in the form of a male profile edge on one side and a female profile edge on the other, where said male profiled edge can be connected to a female edge of an equal adjacent covering panel, preferably according to a direction that runs perpendicular to said top surface. In their bottom face there are strip-shaped recesses that run according to the direction of extrusion and alternate with a number of support strips, of which at least a part has a width S along that bottom face that complies with 1.5T<S<10T, and whereby 0.4T<C<0.7T applies, in which C is the average depth of these recesses. A process extrudes a synthetic plastic plate.
