Abstract: A roll stand for rolls of sheet material allowing exchange of rolls has been invented, wherein the full rolls may be entered into or removed from the roll stand sideways. The roll spindles (16, 17) are at one of their ends journalled stiffly in a first roll holder gable (14), while the other gable (15) comprises at least two supporting arms (26, 27) with supporting bearings (46, 47) for the other ends of the roll spindles. Means (33, 29, 44) are provided to individually loosen the supporting arms from the spindles and moving them aside to make possible the entry or removal of a full roll onto or from the exposed spindle making use of a carriage or the like.
Abstract: A device for a roll spindle for unwinding or winding up a web material comprises a brake mechanism, a clutch between the spindle and the brake mechanism for axial connection of said parts, and means provided to perform two operations in the axial direction, namely a first operation for causing the mechanism to be moved towards or from the roll spindle in the axial direction for the engagement and disengagement, respectively, of the mechanism with and from the spindle, respectively, and a second operation causing the mechanism when connected with the spindle to be moved in the axial direction for lateral adjustment of the web material.
Abstract: In a method and an apparatus for continuous winding-up of a material web on roll spindles where the web is supplied continuously and is arranged to be cut off in conjunction with roll spindle shiftings, a cutting off knife (17) is mounted in a holder (10) together with a brush (16) and a pressure roller for transferring the web onto a new roll spindle. The invention also includes a microcomputer-regulated control system and a gear drive housing (44) which is designed to be rotated together with the roll holder (5) during spindle shiftings.
