Abstract: The invention relates to a method for production of polyester resins containing nanodisperse nanoscale additives as binder for powder paints, whereby firstly at least one precursor compound for nanoscale solid particles to be formed is added to the reaction starting materials during the resin synthesis and distributed in the reaction starting materials. The precursor compound(s) which may be reacted at a temperature between 30? and 260° C., preferably between 80° and 250° C., are reacted to give the desired nanoscale solid particles under the effect of a reaction temperature in the range between 30? and 260° C., preferably between 80? and 250° C., the nanoscale solid particles thus formed being nanodispersedly distributed in the polyester resin.

Abstract: A winder for winding a running web of paper, foil or similar. A support drum of web width is provided, and a winding drum on which the web is wound to a roll. A pair of primary swivel levers each feature on one end a fork for receiving a winding drum bearing and is mounted with its other end in the region of the support roll axis in such a way that the winding drum, in swiveling from a first position above the support roll, will in the running direction of the web approach the support roll while moving around it, passing in the process a primary section until reaching a second position. The winding drum with the still unfinished paper roll is taken over by a pair of secondary swivel levers with an essentially horizontal guideway extending from the second position across a secondary section up to a third position. A contact device forces the winding drum onto the support roll, and a drive is coordinated with the winding drum.

Abstract: A winding machine for winding a traveling web of paper or the like. A carrying drum extends across the web. A first pair of primary levers supports the pins at the end of a cylinder on which the web is to be wound. The primary levers have one end with a fork for receiving a respective journal pin of the cylinder and another end that is mounted in the region of but eccentric to the axis of the carrying drum. The primary levers swing the cylinder over approximately 90.degree. around the carrying drum to a second position. A second pair of secondary swing levers pick up the cylinder at the second position and move it to a third position along a substantially horizontal second pathway. A first drive connected with one primary lever introduces a moment of rotation to the axis of the cylinder moving along the primary path. A sensor detects the radial position of the cylinder and a setting device adjusts the radial position of the first drive in order to align it with the cylinder.

Abstract: A method for transferring a continuously arriving web, specifically a paper or cardboard web, from a finished product roll to a new core rotating at the speed of web travel. The new core bears in the direction of web travel and before the finished product roll on a drum around which loops the web. The web is cut longitudinally, prior to running on the drum, for forming a transfer strip. Before reaching the new core, the transfer strip is severed from the advancing web and passed onto the new core. The web is subsequently cut across its entire width, wherein this cut originates from the longitudinal cut.A drum winder for accomplishing the method wherein the severing device for the transfer strip is arranged before the intake gap between the drum and the new core. A high-pressure water jet is used for severing the transfer strip from the web.

Abstract: An apparatus for winding a continuous web, specifically tear-resistant paper or cardboard web, is preferably designed as a Pope reel winder, and when exchanging a full roll with an empty reel-spool, the latter is in customary fashion placed on the winding drum over which the web initially continues to advance onto the full roll. At the edge of the web, a sickle-shaped catch lever reaches around the upper portion of the empty reel-spool and engages the edge of a web loop to pull it about a portion of the empty reel-spool. Simultaneously, a cutting device can make a transverse cut in the edge of the paper web, and once the web edge has been engaged by the empty reel-spool, the remaining portion of the web tears through essentially without any shock effect.
