Patent number: 6250580Abstract: Process and winding machine for the continuous winding of a web of material onto a reel spool to form a reel. The process includes forming a winding nip between a peripheral zone of a reel drum the reel, guiding the material web over the peripheral zone of the reel drum, positioning the reel in a secondary zone, and displacing and pressing the reel drum against the reel in the secondary zone. In this manner, one of control and regulation of a linear force in the winding nip occurs through the displacement of the reel drum.Type: GrantFiled: February 24, 1999Date of Patent: June 26, 2001Assignee: Voith Sulzer Papiertechnik Patent GmbHInventors: Zygmunt Madrzak, Roland Möller

Patent number: 6173636Abstract: A paper machine for one of making and processing a fiber material web. A plurality of rolls carry the fiber material web. The plurality of rolls include a load roll and another roll defining a nip therebetween. The fiber material web travels through the nip and defines a gore with the load roll on an approach side of the nip. A movable cutoff knife includes a cutting edge positioned in the gore at a slight distance from the nip and adjacent to the fiber material web. At least one impulse exchanger is positioned in association with the cutoff knife. The impulse exchanger is configured to transfer impulse energy to the cutoff knife whereby the cutting edge cuts the fiber material web.Type: GrantFiled: April 15, 1997Date of Patent: January 16, 2001Assignee: Voith Sulzer Papiermaschinen GmbHInventors: Zygmunt Madrzak, Bernd Kaufmann

Patent number: 6129305Abstract: Winding machine for continuous winding of a material web, in particular a paper or cardboard web, onto a reel into a winding roll, having a movable pressing drum, which forms a winding gap with the winding roll, having at least one primary transport device by means of which the reel can be moved along a first guide track, and at least one secondary transport device that guides the reel along a second guide track. To prepare for a reel change, the new reel can be shifted by the primary transport device into a reel-changing position in which a new winding gap is formed between the new reel and the pressing drum. In the reel-changing position, the material web is guided over a circumference region of the new reel.Type: GrantFiled: November 18, 1998Date of Patent: October 10, 2000Assignee: Voith Sulzer Papiertechnik Patent GmbHInventors: Roland Moller, Ralf Preising, Rudolf Beisswanger, Zygmunt Madrzak, Walter Kaipf

Method and apparatus for application of coating medium onto a traveling material web having a splice
Patent number: 6086954Abstract: A method and an apparatus for direct or indirect one-sided or double-sided application of a liquid or pasty coating medium onto a spliced traveling material web, notably of paper or cardboard, includes at least one applicator applying the coating medium at a predetermined point of coating application onto the material web. At least one coating suspension system briefly suspends the application of the coating medium at the point of coating application or at a point of suspension located, based on the direction of travel of the material web, ahead of the point of coating application.

Patent number: 5848756Abstract: A method and device for the winding up of a moving web of paper (9) on a reel spool (11), as large a part as possible of the developing wound roll (12) having a high degree of winding hardness (WH), characterized by the fact that a relatively soft intermediate layer is formed between the wound roll (12) of high winding hardness and the winding core (11). This is achieved in the manner that, during a short initial phase of the winding process, it is ensured that the winding hardness (WH) is relatively slight in the innermost layers of the wound roll (12), whereupon an immediate transition to a relatively high winding hardness (WH) is effected which is being substantially maintained during the rest of the winding-up process. Alternately, the relatively soft intermediate layer can also be created in the manner that the reel spool (11A-11D) has a soft covering (41, 42, 43, 44, 45, 46, 47) on a metal reel spool body (40).Type: GrantFiled: June 9, 1997Date of Patent: December 15, 1998Assignee: Voith Sulzer Papiermaschinen GmbHInventors: Hans-Peter Sollinger, Rudolf Beisswanger, Ulrich Schettler, Karl-Josef Boeck, Zygmunt Madrzak, Karl Rueck

Patent number: 5797561Abstract: An unwinding station for fiber webs, particularly paper webs, features a support each for a new web roll (primary paper roll 16) and for a previous web roll (secondary paper roll) as well as a system for splicing the web leader of the primary paper roll on the fly to the web end of the secondary paper roll. This system allows the so-called flying splice. A drive unit (M) operating selectively as a motor or brake is coupled to the primary paper roll (16). An RPM control (24) or a web draw control (25) is coupled selectively to a control (20) of the drive unit (M) using a switching system (34). An additional drive (M') operating exclusively as a motor is coupled to the primary paper roll (16), and at that, during the period of time between the activation of the drive unit (M) and splicing the web on the fly, independent of the drive unit (M).Type: GrantFiled: July 14, 1997Date of Patent: August 25, 1998Assignee: Voith Sulzer Papiermaschinen GmbHInventor: Zygmunt Madrzak
