  • Patent number: 7112258
    Abstract: A dry end section for a paper-making machine for producing a high-bulk tissue is provided. Such a machine comprises a through-air dryer adapted to finally dry a paper web and a through-air drying fabric configured to transport the web through the through-air dryer. A separating device is included for facilitating separation of the web from the through-air drying fabric. A reel is also provided and is configured to receive the web thereon. The web is received directly on the separating device or on a fabric wrapped about the separating device. In some instances, the web may be compressed between the separating device and an adjacent roll or by a web-compressing device disposed along the fabric transporting the web. The web is then transported to the reel directly from the fabric or other support mechanism extending between the separating device and the reel, without free draw of the web. Associated methods are also provided.

  • Patent number: 6705560
    Abstract: A method is provided for switching reels in a paper machine that includes applying an adhesive onto a continuously running paper web to begin a new paper roll and severing the continuous paper web from the tail end of the newly completed roll. The running paper web is supported by a reel drum and wound onto exchangeable reel shafts in contact with the reel drum in order to form rolls of paper. A hopper with a heater heats an adhesive agent to temporarily lower its viscosity and stickiness for smooth and even applying. A pair of nozzles, mounted on a pair of rodless cylinders and translating therewith, spray jets containing said adhesive onto the web and/or the reel shaft. The web is then advanced onto the reel shaft thereby forming an adhesive interface between the web and the shaft. Tension is applied across the adhesive interface to sever the paper web at the adhesive interface, thereby separating the trailing end of the paper web of the previously completed roll from the current paper roll.

  • Patent number: 6145778
    Abstract: A reel-up for reeling a paper web onto reeling drums (2), comprising stand parts (5) with rails (9), along which the reeling drums (2), rotatably carried by their bearing housings (4), are displaced, a surface winding drum, over which the paper web runs and which is rotatably journalled in bearing housings (13) on the stand parts, a secondary system, and a primary system, having primary arms (24) with gripping members (33) for retaining a reeling drum (2), which primary arms have actuators (28) for moving the reeling drum (2) along the envelope surface of the surface winding drum.

  • Patent number: 5875990
    Abstract: A reel-up in which paper is reeled up on reeling drums to form paper reels, said reel-up comprising two stand members each having a stand rail to support the reeling drum; a surface winding mechanism over which the web runs; and a secondary system with at least one secondary unit for receipt of a reeling drum, wherein the secondary unit comprises first and second secondary bodies which are linearly movably journalled in said stand members. According to the invention each secondary body comprises a lifting mechanism for lifting the reeling drum from the stand rail to a production level in which the reeling drum is free from the stand rails and the load of the paper reel and the reeling drum is taken up by the secondary bodies and transferred to the stand members.
