Abstract: Process and apparatus for winding a running material web, in particular a paper or cardboard web, in which the running material web is wound consecutively on several winding cores, in particular reel spools. At least one cut is made preferably running parallel to the web edge of the running material web and in the web travel direction of the running material web. After the started at least one cut has run through the nip formed by the winding roll and the new winding core, the at least one formed transfer strip which is incorporated in the running material web is detached from the outer circumferential area of the winding roll by at least one directed high-energy air jet that is generated briefly by at least one separator device and simultaneously cuts through. Subsequently, the at least one now detached transfer strip is transferred onto, and preferably applied to, the outer circumferential area of the new winding core by at least one first blower device, in particular a blower shoe.

Abstract: A method is provided using a winder to afford precise adjustment, preferably control of the progression of line force between the reel drum and the wound roll despite unevenness in the surface contour of the wound roll, and ensures that no air entrapment occurs between the individual layers in the wound roll. Further, the “wound in” web tension is maintained during the entire winding process.

Abstract: Linear drive apparatus and process of using the same. The apparatus includes a movable device and a first high-speed thrust device coupled to the movable device. The first high-speed thrust device exerts an acceleration force on the movable device to move the movable device from a ready position. A movable retaining device is coupled to the movable device, so that the retaining device is adapted to hold the movable device in the ready position against the acceleration force. A release of the movable retaining device triggers immediate movement of the movable device via the acceleration force. The process includes positioning the movable device in an idle position, holding the movable device in the idle position with the retaining device, exerting an acceleration force on the movable device while it is being held in the idle position, and releasing the movable device from the idle position by moving the retaining device. In this manner, the acceleration force moves the moving device.
