Abstract: The disclosed device includes a single electric motor for linear and rotary movement with a stator. The stator includes a multi-phase coil arrangement with a plurality of coils or coil sets and a rotor. The rotor is movable in an axial direction of a rotational axis thereof and includes a plurality of poles respectively with at least one permanent magnet The device further includes a control unit operative to determine currents (Ir, Is, It) by calculation formulas and based on at least a number of coils or coil sets of the plurality of coils or coil sets, and an angle of rotation of said rotor and a parameter depending on an axial position of the rotor. Each current (Ir, Is, It) has a current component (Ir?, Is?, It?) for generating a torque and a current component (Irx, Isx, Itx) for generating an axial force, and to supply the determined currents in open loop to the number of coils or coil sets, so that the sum of the currents is zero. Further, at least one of the stator and the rotor, includes a back-iron.

Abstract: A processing system and a method for processing a flexible substrate (e.g., a web) use a tensioner with a vacuum plate that can be moved along a transport direction of the flexible substrate with an indexer that intermittently moves the flexible substrate for processing. The tensioner and the indexer are controlled so that a relative speed between the indexer and the vacuum plate of the tensioner is maintained above a predefined threshold under all working conditions, even when the flexible substrate is stopped.
