    摘要: A paper drying apparatus including a first rotatable drum, wherein the first rotatable drum has an inner perimeter and an outer perimeter and a second rotatable drum having an inner perimeter and an outer perimeter. A fabric sheet for carrying a paper web is provided, wherein the fabric sheet passes around the outer perimeter of the first rotatable drum and proceeds to next pass around the outer perimeter of the second rotatable drum. As the fabric sheet conveys the paper web around the first rotatable drum, a drying air is applied to the paper web in a direction from the inner perimeter of the first rotatable drum toward the outer perimeter of the first rotatable drum, further passing through the paper web. As the fabric sheet and paper web proceed around the second rotatable drum, a drying air is applied to the paper web in a direction from the outer perimeter of the second rotatable drum toward the inner perimeter of the second rotatable drum, further passing through the paper web in a similar direction.

    摘要: The present invention relates to biaxially undulatory single-ply and multi-ply tissues, single-ply and multi-ply towels, single-ply and multi-ply napkins and other personal care and cleaning products as well as novel creping blades and novel processes for the manufacture of such paper products. The present invention is directed to tissue and towel product having highly desirable bulk, appearance and softness characteristics produced by utilizing a novel undulatory creping blade having a multiplicity of serrulations forced in its rake surface which presents differentiated creping angles and/or rake angles to the web as it is being creped. The invention is also directed to a novel blade having an undulatory rake surface having trough-shaped serrulations in the rake surface of the blade. The undulatory creping blade has a multiplicity of alternating serrulated sections of either uniform depth or a multiplicity of arrays of serrulations having non-uniform depth.

    摘要: A creping system includes a Yankee dryer rotatable about its axis, a blade support mechanism which includes (a) a pair of guide rails, (b) a fixed attitude linear bearing engaging and translatable along each of the guide rails, each fixed attitude linear bearing being mounted on a block and (c) a combination linear-rotary bearing being carried by each block, the axis of each combination linear-rotary bearing being parallel to the generators of the surface of the Yankee dryer and collinear with the axis of the other combination linear-rotary bearing. A stub shaft engages each combination linear-rotary bearing, each stub shaft being translatable along, and rotatable about, the axis of its respective combination linear-rotary bearing. A blade holder is mounted between the stub shafts, and a blade mounted on the blade holder for engagement with the surface of the Yankee dryer. The blade support mechanism allows the creping angle of the blade to be adjusted and maintained within a desired range by allowing adjustment of the creping blade angle to compensate for changes in creping angle due to flexure of the blade and flank wear on the blade. This adjustment is permitted while allowing the blade holder to be (a) translated in a direction parallel to the generators of the surface of the Yankee dryer, (b) rotated about the axis of the stub shafts; and (c) urged inwardly toward, or outwardly away from, the surface of the Yankee dryer.
