Patent number: 8210077Abstract: A device (1) for cutting labels in a labelling machine, including a cutting roller (2) having at least one blade (3) co-operating with a fixed counter-blade (4) able to be operatively associated to the roller for cutting the labels, a mechanical shaft (5) whereon is keyed said cutting roller (2), a frame (6) to support said mechanical shaft (5) and a heat exchanger circuit containing an operating fluid. Precisely, a first portion (9a) of said circuit is constructed on said support frame (6) and a second portion (9b) of said exchanger circuit is constructed on said mechanical shaft (5), said exchanger circuit thermally interacting with said frame (6) and with said cutting roller (2). The device further includes an impeller for generating a flow of said operating fluid within the heat exchanger circuit, said impeller for generating a flow of said operating fluid being connected to the mechanical shaft (5) and being operatively inserted in said heat exchanger circuit.Type: GrantFiled: December 20, 2007Date of Patent: July 3, 2012Assignee: Sidel Holdings & Technology SAInventors: James Carmichael, Massimiliano Dalcielo, Marco Ferri

Patent number: 5933988Abstract: In an ironing machine with a rotary ironing cylinder (14) comprising heating means (42) housed in an intermediary space (40) between the cylinder (14) and a fixed internal tube (34), air circulation is ensured inside the cylinder. Two ventilators (62, 68) take the air from regions at the ends of the space (40) via aspiration apertures (46, 48) and deliver it to a central area of the space via expressing apertures (50, 52).Type: GrantFiled: February 27, 1998Date of Patent: August 10, 1999Assignee: Electrolux Systems De BlanchisserieInventor: Michel Adler

Patent number: 5915648Abstract: A drum for guiding a material web, in particular a paper web. The drum has a jacket and a hollow interior. A respective cover at each end of the jacket. A respective bearing journal at each cover for supporting the roll to rotate. The jacket has a plurality of passage openings for passage of air therethrough. At least one and perhaps two impellers inside the interior of the drum, each having a suction side for drawing air into the drum through the passage openings. A pressure side at the other side of the impeller. Air exits the drum from the pressure side of the impeller through passage openings and/or an opening in a cover.Type: GrantFiled: November 20, 1997Date of Patent: June 29, 1999Assignee: Voith Sulzer Papiermaschinen GmbHInventors: Zygmunt Madrzak, Karl Ruck

Patent number: 5277690Abstract: A roll, specifically a paper machine press roll, with a hollow rotatable roll body features a roll shell and on at least one of its two ends a hollow roll journal. A guide body which is stationary or fastened to the roll body extends through the interior of the roll body and forms with the roll shell a channel system through which a tempering medium flows. For purposes of using air as tempering medium, a pressure blower and/or a suction blower are connected to the channel system. The channel system and the blower(s) are so dimensioned that an air flow velocity above 10 m/sec will materialize in the channel system.Type: GrantFiled: February 18, 1993Date of Patent: January 11, 1994Assignee: J. M. Voith GmbHInventor: Christian Schiel
