    Abstract: The invention relates to a film store and method for dynamically storing a strip-like label film, wherein the film store comprises at least one storage region with an upper carriage and a lower carriage as well as deflection rollers fastened thereto for the label film. The label film is guided along a transport path extending in a meandering manner between the upper carriage and the lower carriage, and the size of the film store is adjusted by the upper and lower carriage moving in opposite directions while mutually compensating for weight. Because the upper carriage and the lower carriage are moved toward one another or away from one another by a torque-controlled or force-controlled servo motor and/or the servo motor tensions the label film between the deflection rollers, the storage dynamics and the storage capacity can be optimized while maintaining a maximum permissible strip tension in the label film.

    Abstract: A rotary machine for the treatment of containers is described. This rotary machine comprises a stationary underframe, a rotatable container table for receiving the containers, a motor designed as an internal rotor for direct drive of the container table, a bearing for supporting the container table and/or a non-rotatably connected supporting structure on the underframe radially outside the motor, and a rotary encoder for determining the rotational position of the container table. By positioning the rotary encoder radially outside the motor, the accuracy of the rotary position determination can be improved, especially for rotary machines with comparatively large pitch diameters and the accessibility of the rotary encoder for maintenance measures.

    Abstract: A linear drive for a stretch and/or blow moulding machine has a force sensor for detecting actual force absorption of the linear drive during operation, a storage device in which data for a desired force absorption during operation are stored, and a comparison device for comparing actual force absorption with desired force absorption and a signal emitter for outputting a signal if a previously defined deviation between desired force absorption and actual force absorption is exceeded. Also provided is a method for determining a friction coefficient of a linear drive for a stretching and/or blow moulding machine, by determining a desired force absorption of the linear drive during operation, detecting using a force sensor, actual force absorption of the linear drive during operation, comparing actual force absorption with desired force absorption, and outputting a signal if a previously defined deviation between desired force absorption and actual force absorption is exceeded.

    Abstract: A labeling unit and a method for applying labels to containers are described. According thereto, the labeling unit comprises an unwinding device for unwinding a label-backing tape from at least one supply reel, a processing device for separating the label-backing tape into the individual labels and for transferring the labels onto the containers, and, arranged in-between, a loop buffer which is variable in size and is intended for temporarily storing the label-backing tape. Owing to the fact that the loop buffer comprises at least two, pivotably-mounted for changing the size, deflecting pulleys for the label-backing tape, and is designed and arranged to provide the sole, temporary storage between the supply reel and the separation unit, the label-backing tape can be temporarily stored with comparatively high storage dynamics and sufficiently high storage capacity for changing the label-backing tape, and also with a low outlay on an apparatus.

    Abstract: A device for transporting containers comprises at least two transport devices for the containers, at least two servo motors, at least two position sensors, and at least one control unit. The at least one control unit is to control the at least two servo motors, by closed-loop control, based on a comparison of positions determined by respective position sensors of the at least two position sensors and respective target positions. The at least one control unit is further to bring the at least two servo motors to a standstill in the event of a fault of a position sensor, wherein: a) a servo motor is brought to a standstill in a closed-loop manner using the position if it is determinable by the position sensor, or b) the servo motor is brought to a standstill in an open-loop manner based on the target position if the position is not determinable.
