Abstract: In order to achieve that portions are visually appealing, i.e., centered, with uniform slice distance in a longitudinal direction and also not differing too much in a transverse direction and in particular not resting on a sealing edge of a trough, the corresponding actual arrangement of a portion is determined directly in a packaging machine by means of a camera and, if deviation from a target arrangement is too great, production parameters are changed in an upstream portion production unit, in particular a portioning belt and/or a cutting unit of a slicing machine, and/or an upstream portion delivery unit and/or an upstream package delivery unit.

Abstract: The disclosure relates to a device for a packaging process, wherein the device is provided in the form of a step-by-step packaging machine, or is configured as a step-by-step packaging line.

Furthermore, the disclosure relates to a corresponding method.

Abstract: The invention relates to a method for cleaning a vacuum pump embedded in a technical system. Water is provided for the cleaning, and a rotational speed of the vacuum pump is adjusted to a value in a cleaning rotational speed range. A defined amount of cold water and/or warm water is supplied to the vacuum pump and the vacuum pump is rinsed with the water during a predetermined time period. After letting the water escape from the vacuum pump, the vacuum pump is dried by aeration with gas or a gas mixture. The invention also relates to a cleaning system for cleaning the vacuum pump.
