摘要： The invention relates to an apparatus for winding a paper web. It comprises a rotatably mounted reel spool (3) onto which paper can be wound and an endless flexible belt (5) which is permeable to air and supported by support rolls (12). The flexible belt is positioned adjacent the reel spool (3) to engage the web against the reel spool during winding such that the endless flexible belt is deflected from the path of travel. The flexible belt has a web-contacting side (6). An actuator (9) is arranged to position the reel spool (3) and the flexible belt relative to each other to vary the amount of deflection. The apparatus further comprises a cleaning device (11) with at least one nozzle for blowing air against the web-contacting side of the flexible belt at a point where the flexible belt is not in contact with the paper. The invention also relates to a method of removing dust particles.

摘要： A method for monitoring a machine element in a paper finishing machine (10). The machine element mounted for rotation machine elements (16-19) equipped with a sensor assembly (24) measuring force or pressure, and a counter-pair (15, 20, 33, 44) for said machine element. The machine element is made to rotate against the counter-pair, a measurement signal (25) is generated between the machine element and the counter-pair with the sensor assembly, and recording a reference cross-directional profile (21) of force or pressure generated. Condition monitoring (38) of vibration with the reference profile is by comparison of current signals with the reference so as to detect periodic variation (39.1, 39.2) in the cross-directional pressure profile, and producing visual information (37) from the analysis for monitoring. The invention also relates to a corresponding system, a rotating machine element for the method or the system, and a computer program product.

摘要： Described herein are methods and systems for minimizing folding defects when rolling a paper product. The method comprises rotating a roll in a manner that draws a paper product toward the roll. The location of a pick-up point between the roll and the paper product is altered by influencing the air pressure experienced by the paper product. This may be accomplished by flowing air in one of several manners described in the specification.
