A torque support for absorbing drive torques of at least one shaft drive, having two first force-conducting elements, each of which is rotatably fixed to the shaft drive at a distance from one another by a first end, and having a support element arranged at a distance from the shaft drive, to which support element the first force-conducting elements are each fixed rotatably and at a distance from one another by a second end opposite the first end, and spaced apart from one another, and having two second force-conducting elements which are each fixed at a first end to the support element in a rotatable manner and spaced apart from one another and are each fixed at a second end, opposite the first in each case, to a fixed element which is independent of the shaft drive in a rotatable manner and spaced apart from one another. A corresponding roller arrangement is further disclosed.

Calender for treating web materials, comprising a structure for supporting two heated rollers forming a nip, wherein each roller has surface reliefs (RR) and in an operational setting of the calender the reliefs of one roller are radially opposed to those of the other roller, each roller rotates with a predetermined angular speed around its axis, the rollers are heated by heating means, and each roller undergoes an axial elongation as a consequence of its heating. The calender comprises detection means (E1, E2; IS) adapted to detect the axial elongation of each roller and a programmable control unit (UCP) connected to the detection means and to the heating means. The control unit is programmed to determine the difference between the axial elongations of the rollers and emitting an alarm signal if the absolute value of this difference is greater than a limit value.

A fiber body production apparatus includes a forming mechanism that forms a mixture, a pressing unit that transports the mixture while pressing the mixture, a peeling blade that peels the mixture from the pressing unit, a cleaner that cleans the pressing unit, and a shaping mechanism that shapes the mixture, after a rear end of the mixture passes through the pressing unit, the pressing unit is reversely rotated to move foreign matter adhering to the peeling blade to the pressing unit, after the roller is reversely rotated by a predetermined amount, the pressing unit is rotated forward to transport the foreign matter, compress the foreign matter on the pressing unit, and cause the compressed foreign matter to pass between the peeling blade and the pressing unit, and the cleaner removes the transported foreign matter from the pressing unit.

A process for the production or treatment of a fibrous web, in particular a paper or cardboard web, includes the following steps: a. drying of the fibrous web in a dryer section; b. subsequent cooling of at least one first side of the fibrous web by way of convection cooling, whereby the fibrous web has a temperature of 65 C. or less on at least the first side after cooling, in particular 50 C. and less; c. apply steam to at least the first side of the fibrous web, in particular the temperature on the first side after steam application is at least 70 C., optionally more than 80 C. or 90 C.; and d. treatment of the fibrous web in at least one calendering nip.
