In a roll for a paper-making machine, a torque which is needed for rotating the roll is reduced and the drive power and a running cost are reduced. A hollow perforated roll in the paper-making machine is rotatably mounted on a bearing housing via a bearing. A cylindrical stationary center shaft extends in an axial direction through a center of the roll and has a perforated circumferential surface. At least two fins extending in an axial direction are mounted on an outer circumferential surface of the center shaft within the hollow interior of the roll, their outer edges being spaced from the inner circumferential surface of the perforated roll. Radially extending disc-like fins are also mounted on the outer circumferential surface of the center shaft perpendicular to an axis of the center shaft with their outer circumferential edges being spaced with a slight gap from the inner circumferential surface of the perforated roll. At least two of the axially extending fins are circumferentially located in the vicinity of contact points with web members wound around the perforated roll.

A method for changing spools in which a sheet continuously supplied to a reel drum is wound onto a new spool, comprising the steps of bringing the new spool held on an arm at a waiting position into contact with the reel drum; cutting the center part of the sheet with two cutting devices along two approximately parallel cutting lines in the running direction of the sheet at a location on the reel drum upstream in the running direction of the sheet; supplying an adhesive to an area between the cutting lines and letting the adhesive adhere onto a surface of the new spool; and moving said two cutting devices toward the two respective edges of the sheet so as to cut the sheet into a triangular shape. An apparatus for changing spools is equipped with a holder for holding the new spool at a waiting position and bringing the new spool into contact with the reel drum when a new spool replaces the old one; two cutting devices installed so as to be able to contact with and move away from the sheet and to move from the central part of the sheet to the respective side edges at an upstream position in the direction of the sheet movement on the reel drum; and a supplier for supplying an adhesive material onto the sheet surface installed between the cutting devices and the reel drum.

A coating apparatus for applying coating liquid onto a web which is being transported as wrapped around a backing roller includes a chamber from which the liquid is applied to the web and a blade for scraping the applied coating liquid into a film having a constant thickness. A partition plate divides the inside of the chamber into upstream and downstream sections with respect to the direction of travel of the web. A plate-like body resiliently held in contact with the web is mounted to an upper portion of the partition plate, and a plurality of holes are formed in a lower portion of the partition plate.
