Abstract: Support connections. Support connection are provided between two rolls, with the roll covering of at least one roll being journalled on a carrier via a plurality of support elements as well as being displaceable relative to the carrier along the pressure plane, with support portions that receive the carrier being connected via elongated connection parts, having thickened portions on both ends thereof, with the thickened portions being connected in a form-locking manner with respective recesses of the support parts in a removable manner, with the connection parts, between the thickened portions, in a direction parallel with the pressure plane, being substantially longer than laterally extending with respect thereto and, between the thickened portions, at least one elongated opening being provided therein, with the opening dividing the connection parts in the direction of the roll axis.

Abstract: A pressing roll for the production or treatment of web or band shaped materials, particularly fiber webs or bands, with the roll jacket of the pressing roll being rotatably arranged about a carrier and journalled via a pressing device, with the pressing device having at least one support element that includes at least one supporting pressing element acting in the direction of a pressing area and being supported on the carrier, with the at least one support element being displaceable in the circumferential direction as well as being radially movable relative to the pressing element and which, in the circumferential direction, is supported on a spacer on a limit stop, attached to the carrier, via at least one spacer, the spacer permitting a radial movement relative to the limit stop in the transition between an unloaded and a loaded condition of the support element at a substantially fixed support point of the spacer at the limit stop or at the support element, with a low friction support, in the circumferentia

Abstract: Process an device for guiding a material web. The invention pertains to a method and apparatus for guiding a material web or strip thereof toward and around a movable guide element, in a simple and safe manner, which is achieved in that, for example, in the press portion of a papermaking machine, a strip of a paper web is brought into the vicinity of a rotating guide roller and, there, an air jet extending nearly tangentially, relative to the rotatable guide roller of a blast nozzle, serves for the transport to a subsequent unit.

Abstract: A roll assembly comprising a rotatable roll (1 in FIG. 2) and a second roll (2 in FIG. 2) cooperating therewith, in which a pressing element (17) to effect displacement between the rolls along a pressure plane of the roll assembly is located in one of the rolls (1,2) and in which both rolls are supported at either end by respective support members (5,6). Prior to operation of the roll assembly, dumbbell-like shaped connecting parts (7) installed in corresponding cut-outs (9) in the support members (5,6) are tensioned and thereby securely form-locked by actuating the pressing element (17). Locking action is released by subsequent deactivation of the pressing element (17) after which the connecting parts (7) can be withdrawn. Two principal advantages of this arrangement, are the compacter construction, enabled by the fact that the frame no longer bears the pressing forces of the roll assembly, and the ease and speed with which components such as rolls, roll jackets or felt belts can be changed.
