摘要:
A dry end of a tissue machine is made shorter by close-coupling a reel-up to the drying section and supporting the web from the drying section to the reel-up by a foil or a belt such that web stability is maintained, thus allowing high-speed operation. The foil's downstream edge can form a nip with the paper roll and nip load can be controlled by controlling pivotal movement of the foil. The reel-up can include a calendering belt for calendering the web as it passes through a nip between the belt and a reel drum supported on the belt, and a rotatable reel spool on which a paper roll is wound in nipping engagement with the reel drum. Alternatively, the reel drum can be eliminated and the paper roll can be supported on the belt. A composite shaftless core for winding is also disclosed.

A method, apparatus and system for making cushioning product, and a roll tensioner therefor apply frictional resistance to the periphery of a roll of material to be converted into cushioning product with at least one roll support member which supports the roll in addition to applying frictional resistance to rotation. Efficient operation is attained automatically in that the frictional resistance applied and also the pulling profile exerted on the material during unwinding of the roll are changed as a function of weight and/or other characteristics of the roll of material to be converted into cushioning product.

摘要:
A property of a paper web is measured using one or more reflectance measurement sensors emitting measuring beams onto the web and receiving the beams reflected from the web, from which the web property is deduced. The web is supported on a web support during the measurement, such as on a passive or active airfoil or fabric. One or more measurement sensor(s) can be integrated within an active airfoil, and can comprise a plurality of optical fibers having sensing ends arranged in the airfoil such that the sensing ends of the fibers face the moving paper web through one or more apertures in a web-supporting panel of the airfoil. Alternatively, a traversing sensor can be mounted within the airfoil. Other embodiments include a reflectance sensor mounted adjacent an airfoil or other web support such as a through-air drying fabric or a support belt for the web.

A system for creating and dispensing cushioning dunnage is small and permits flexible installation configuration options for a single or for multiple packing stations. A compact apparatus of the system is capable of being pivotally mounted as a unit on a stand and includes a motor and a material feeding arrangement driven by the motor for pulling material from a supply roll of the material supported on a stand of the system, and feeding it through the apparatus. A plurality of material shaping members upstream of the feeding arrangement shape the material in the apparatus to convert it into a continuous strip of cushioning product. A perforator driven by the motor perforates the material at spaced locations along the length of the material to allow an operator to manually rip a desired length of cushioning product from the material being dispensed from the apparatus.

A surface winder and method in which a stationary upper winding roll, a lower movable winding roll and a rider roll form a three roll cradle, the lower winding roll being reciprocated to control the position of a partially wound core until the rider roll returns to cradle position after permitting passage of a previously wound log and in which a compensator roll is provided to control web slack after cutoff and transfer.

A flat compressible material is roll-formed into a cylindrical package by a belt drive. The diameter of the rolled package is controlled so that a fixed predetermined length of material forms a rolled package of a predetermined diameter. The length of belt drive in contact with the material is proportionate to the length of the material fed into the belt drive, and holds the finished package size to a predetermined diameter.
