The disclosure relates to a continuous cleaning method for cleaning a moving fabric in a paper machine. The method uses one or more cleaning stages. In one embodiment, one cleaning stage applies steam to heat and soften contaminants on the fabric followed by the application of water, preferably superheated water, to remove the contaminants. Another cleaning stage may apply hot water, steam and/or superheated water via an encapsulated shower and evacuation chamber making it possible to clean the width of the fabric without substantial rewet.

Process for cleaning a transport belt for manufacturing a paper web

Described herein are methods and systems for minimizing folding defects when rolling a paper product. The method comprises rotating a roll in a manner that draws a paper product toward the roll. The location of a pick-up point between the roll and the paper product is altered by influencing the air pressure experienced by the paper product. This may be accomplished by flowing air in one of several manners described in the specification.

The disclosure relates to a method for trimming unwanted edges from a moving paper web. The disclosure also relates to the trimming of unwanted edges while the web is traveling on a structured papermaking fabric. The method uses a water nozzle having a diameter of 0.02&#x2033; or less. The method also includes the removal of the unwanted edge trimmings to a trim chute through the use of moving air, for example, an air knife. The disclosure also relates to an edge trimming apparatus.

Sheet edge trimming and removal from a structured paper fabric

A method of moist creping absorbent paper base sheet includes forming a nascent web including at least a major portion of flattened ribbonlike cellulosic fibers of recycled fiber. A creping adhesive coating including an admixture of polyvinyl alcohol and a polyamide crosslinked with epichlorohydrin is applied to a Yankee dryer. The nascent web is passed through a nip, defined between a suction pressure roll and the Yankee dryer, having a controlled loading. The nascent web is adhered to the Yankee dryer and dried on the Yankee dryer to a moisture content corresponding to a sheet temperature, immediately prior to the creping blade, of from about 110&#xb0; C. to about 121&#xb0; C. The nascent web is creped at a sheet temperature of from about 110&#xb0; C. to about 121&#xb0; C. from the Yankee dryer with an undulatory creping blade bearing against the Yankee dryer to form a moist biaxially undulatory web, which is dried.

Method of moist creping absorbent paper base sheet

A paper machine configured as a swing machine capable of producing both light and heavy grades providing a Yankee hood split into a wet end half and a dry end half, at least one hood half being a flex-hood half wherein the supply for that half is capable of being run with either combustion heat or recycled heat and is capable of either recirculating the exhaust from the hood or discharging it to the atmosphere. The heater for the flex-hood half comprises both a primary combustion heat source and an indirect heat source capable of extracting by-product heat from another operation. The exhaust system for the flex hood half is capable of being run in either a straight through mode or in a recirculating mode.

Energy-efficient yankee dryer hood system

A method of manufacturing absorbent sheet is directed to a wet-press/fabric-crepe process wherein add-on of adhesive to the Yankee surface is at relatively low levels, yet sheet transfer is maintained and production increased. Materials are selected and process parameters are controlled such that a paper machine can be operated for at least 4 hours before the Yankee coating needs to be stripped. Preferably, average increase in Yankee hood temperature is less than 1&#xb0; F./minute during a production interval.

Fabric-crepe process with prolonged production cycle and improved drying

Fabric-creped absorbent sheet has an MD bending length of about 3.5 cm or more as well as an absorbency of about 3 g/g or more. The sheet is preferably produced without through drying or dry creping and is a low-dust product especially suitable for automatic towel dispensers.
