Abstract:
An electrostatical powder coating method starts out from a metallic surface provided with an oil film as a protection against corrosion during storing and transportation. Resin powder is applied to the surface without prior removal of the oil film. The powder layer is melted in a furnace and subsequently hardened by cooling. It is preferred that an amount of heat is supplied by the furnace which is sufficient to evaporate the oil. Preferably, an oil is used which is stable during heating as long as it remains on the work piece surface. This includes the possibility that all of the oil or at least some components thereof diffuse and evaporate through the powder layer during heating or, alternatively, that part or all of the oil remains on the work piece during the heat treatment and mixes with the powder layer. In both cases the quality of the resin coating is not deteriorated by the oil film.
Abstract:
A method is provided to control a paper-processing machine. Following an occurrence of at least one error, the error is automatically detected with at least one detection device. Following the detection of the error, a measure is automatically introduced to counteract the error. The measure is then canceled at least in part if the error no longer occurs or the machine is stopped completely if the error is still detected by the detection device following completion of a predetermined criterion.

Abstract:
A method for operating a collection system for printed products includes drawing off the printed products from discharge device(s) disposed at corresponding discharge point(s) in the collection system. The printed products are deposited on a collection section during a cycle period of the discharge device(s) so as to form a bundle of printed products. The bundle is transferred to a subsequent conveying mechanism having receiving pockets. It is determined whether at least one missing printed product exists due to an incorrect drawing off from the discharge point(s). A repair process is initiated and controlled in which the at least one missing printed product is drawn off from the corresponding discharge point(s) at a time corresponding to a subsequent recurrent pocket-related cycle of the subsequent conveying mechanism in a subsequent cycle period of the discharge device(s). The at least one missing printed product is inserted in the relevant receiving pocket.
