Abstract: A method and a device suitable for carrying out the method for analyzing technical system and/or machines and/or facilities is described. The device includes a database with a number of diagnoses. At least one attribute is associated with the diagnoses and at least one symptom description representing the technical system is associated with the attributes. An exception situation of the system is identified based on the attribute-related or symptom-related analysis of the diagnoses. Those diagnoses that are associated with the attribute and whose symptom description has a value that differs from an expected result, are evaluated and outputted. Based on an additional attribute, a particular diagnosis associated with the additional attribute is identified from the already identified diagnoses, whose symptom description has a value different from the expected result, and outputted.

Abstract: Veneer panels which are to be joined in a plurality of layers one above the other and one behind the other are assembled and glued to form an endless strand of veneer laminates. In the process, the veneer panels are first fed in through a glue-application machine which applies a layer of glue on a top side of the veneer panels onto a buffer belt. The veneer panels are then transferred from the buffer belt to a horizontally reversing feed belt which forms on a roller table a first veneer assembly comprising a plurality of veneer panels. The first veneer assembly is raised about its front end by an angle .alpha. into an oblique position so that veneer panels of a subsequent veneer assembly can be threaded into the first veneer assembly using the horizontally reversing feed belt. The first and subsequent veneer assemblies are thereby combined into a veneer-panel strand, and transferred to a continuously operating prepress and press.
