摘要:
Apparatus for forming an extended nip between a mating roll and a shoe roll for treating a product web, in particular a paper web, the roll axes of which lie in a loading plane E, having a mating roll which is supported via in each case one roll-end assembly on in each case one bearing in a first bracket, having a shoe roll which has stationary bearing journals which are supported in each case via a bearing in in each case one second bracket, one of the brackets being fastened to a stand, and having releasable devices for connecting the brackets to one another, the releasable connecting elements comprising connecting lugs which are guided displaceably in grooves of one of the brackets between a locked position and at least one unlocked position along connecting axes, each connecting lug having a slot which extends parallel to a connecting axis and through which fastening pins which can be inserted in the locked position into one and the other bracket can be inserted and can be brought into engagement with opposite force action faces of the respective slot.

Apparatus for forming an extended nip between a mating roll and a shoe roll for treating a product web, in particular a paper web, the shoe roll having a stationary support and a flexible roll cover which can rotate around the beam and which, in the region of the extended nip, is supported on a pressure shoe arranged on the support and whose ends are fixed on both sides in antifriction-mounted rim discs which are mounted via axially displaceable bearing rings on bearing sleeves fixed to the supporting element, bearing sleeve and bearing rings in each case forming an axially and double-acting cylinder/piston unit, whose pressure chambers are connected to pressure lines for an ability to move the bearing rings axially when pressure medium is applied.

A control device of an automation system, which is configured to control a plant, such as a production plant, including using an AI system, is provided. In an application of the control device, the device monitors the production with regard to the quality of the objects produced, for example, with regard to the presence of fault cases. The AI system is trained in advance based on a plurality of known states of the objects, so that the AI system may be trained for the occurrence of new, previously unknown states, where only a small number of example cases are required.
