    摘要： A web cut-off device including a frame defining a piston chamber, a piston movable in the piston chamber, a cutter blade attached to the piston such that upon movement of the piston in a first direction, the cutter blade is adapted to engage and cut a web, at least one pressure chamber and lower connecting ducts for connecting the pressure chamber(s) to a lower part of the piston chamber. The ducts opening directly into opposed side walls defining the piston chamber such that the piston operates as a valve between the piston chamber and the pressure chamber(s). The device also includes at least one return pressure duct in communication with an upper part of the piston chamber such that upon introduction of pressure into the return pressure duct(s), the piston is moved in a second direction opposite to the first direction, and at least one bottom duct in communication with a bottom of the piston chamber such that by introducing pressure into the bottom of the piston chamber via the bottom duct(s), movement of the piston in the first direction is initiated and by evacuating pressure from the bottom of the piston chamber via the bottom duct(s), the piston is maintained stationary in the piston chamber. A method for cutting a web using the device is also disclosed.

    摘要： A continuous web (W) is reeled up on a center-drive assisted reeling core (C2, C3) to form a machine reel (R), and the reeling core (C2, C3) moves when the center drive (PD, SD) is coupled to the end of the reeling core. The rotating movement and torque necessary in the center drive (PD, SD) are transmitted from a stationary drive motor (PM, DM) to the end of the reeling core (C2, C3) by a power transmission (T) equipped with one or more joints, wherein the need to move the drive motor (PM, DM) along with the movement of the reeling core (C2, C3) is avoided. In a preferred embodiment of the invention the power transmission (T) is implemented by a belt drive, wherein by selecting the belt transmission in a suitable manner, it is also possible to avoid the need to use a separate gear system.
