摘要： The invention relates to a calender intended to calender a paper or board web (4), which calander comprising a calendering section, in which there are at least two members, such as rolls (1, 2, 3), in nip contact, between which the web (4) being calendered is arranged to run. For reducing the moisture and heat leaving the web (4) while it is being calendered a wall (16, 17), covering at least part of the calendering section, is formed from the web (4) being calendered by changing its direction of travel.

摘要： An apparatus for doctoring a roll surface including a pivot bar adapted to be mounted on a doctor back and which the pivot bar defines an upwardly projecting fulcrum. A first shelf projects forwardly beyond the fulcrum and a top plate pivotally supported on and projecting forwardly beyond the fulcrum overlies the first shelf. The top platen is held downwardly against the fulcrum. Blade support members are carried by and cooperate with the top plate to define forwardly open slots, which slots are configured and dimensioned to receive a rear edge of a forwardly projecting doctor blade. The blade support members have rearwardly projecting second shelves underlying the first shelf and a loading mechanism is interposed between the first and second shelves for pivoting the top plate on the fulcrum in a direction urging the doctor blade against the roll surface.

摘要： A paper web is smoothened by passing the web through a pre-calender device on a paper machine before the application of a coating. The pre-calender device comprises at least one pair of steel rolls, one of which is heated, and a liquid application device which applies a thin film of water to the surface of the web which contacts the heated roll before the web enters the nip between the rolls. The web is then dried after exiting the nip either by wrapping the heated roll and/or by applying heat externally to the web.

摘要： In a roll nip (5) formed between a shoe press roll (1) having a concave, plane or slightly convex press shoe (11), a flexible jacket (15) and a hot counter roll (3), the jacket (15) may be damaged by the heat from the counter roll (3) upon a web break. To avoid this, the roll nip (5) is opened by removing one of the press shoe (11) and the hot counter roll (3) from the other, so that the jacket (15) resumes a generally cylindrical shape having an arched portion located across the shoe (11). Then, a force is applied inside the roll jacket (15), directed away from the roll nip (5), to tension the roll jacket (15) over the leading edge and the trailing edge of the press shoe (11), so as to reduce the height of arch of the arched portion over the shoe (11) sufficiently to ensure removal of the jacket (15) from contact with the hot counter roll (3). Preferably, the force against the inside of the jacket is applied by means of a tensioning shoe (61). Suitably, the tensioning shoe is operated by a linear actuator (59), e.g. a fluid force actuator, carried by a support beam (17) that extends axially through the flexible jacket (15).

摘要： The present invention concerns a method of producing a calendered, coated fibrous web, according to which method a fibrous web is coated with a coating colour containing a coating pigment, and the coated fibrous web is calendered. According to the invention, at least 1%, preferably 10 to 100% of the weight of the pigment comprises calcium oxalate, and calendering the coated web by online calendering. The properties of the calcium oxalate pigment are so advantageous for calendering that it is possible to obtain a reasonably high gloss already with a machine calender (online calendering), which will eliminate need for a separate offline calender in the production line of matt surface papers.

摘要： In the method for precalendering a paper or paperboard web (W) a web that has undergone earlier dewatering stages is calendered to attain a suitable surface for the coating process. The web is calendered (C) one-sidedly in such a manner that the absorption level of the second side (W2) of the web entering the calendering, which is higher than the absorption level of the first side (W1), is reduced in the calendering nearly to the same level or at least to the same level with the first side (W1).

摘要： A method for increasing caliper control of a fibrous web as the web is wound onto a roll is provided. The method includes winding the fibrous web containing cellulosic fiber onto the roll to form a wound product and conveying the web through a nip prior to winding the web onto the roll. The nip is configured to apply a pressure to the web to selectively decrease the caliper of the web as the web is wound onto the roll. Also disclosed is a system for controlling the caliper of the fibrous web in which a calender device forms a nip through which the fibrous web is conveyed. The system includes an adjustment device, which is configured to adjust the nip of the calender device to increase pressure on the fibrous web as the diameter of the roll increases thus increasing uniformity of the caliper of the fibrous web.

摘要： A process for increasing the tactile properties of a base web without adversely affecting the strength of the web is disclosed. In general, the process includes the steps of placing a base web in between a first moving conveyor and a second moving conveyor. The conveyors are then wrapped around a shear inducing roll which creates shear forces that act upon the base web. The shear inducing roll typically has a relatively small diameter. In some applications, more than one shear inducing roll may be incorporated into the system. In other applications, the shear inducing roll can also be a nip roll for decreasing the caliper of the base web. The shear inducing roll may be stationary, as in the form of a stationary shoe with a convex edge, or may rotate. In one embodiment, the shear inducing roll can rotate on an air bearing.
摘要翻译：公开了一种用于增加基底纤维网的触觉性能而不会不利地影响纤维网强度的方法。通常，该方法包括将基底片放置在第一移动输送机和第二移动输送机之间的步骤。然后将输送机缠绕在剪切诱导辊上，该剪切诱导辊产生作用在基底纤维网上的剪切力。剪切诱导辊通常具有相对较小的直径。在一些应用中，可以将多于一个的剪切诱导辊并入系统中。在其他应用中，剪切诱导辊也可以是用于减小基底网的厚度的夹辊。剪切诱导辊可以是静止的，如具有凸缘的固定鞋的形式，或者可以旋转。在一个实施例中，剪切引导辊可以在空气轴承上旋转。

摘要： A process is provided for operating a calender roll including a roll jacket surrounding an inner chamber. The process includes creating an active oscillation in the inner chamber that acts upon the roll jacket. By creating an oscillation within the calender roll, the appearance of undesired bar rings, which form on the external surface of the roll jacket due to operational exciting forces, is avoided. Furthermore, calender roll is provided including a roll jacket surrounding an inner chamber, and at least one actuator provided within said inner chamber acting upon said roll jacket.
