Abstract: In order to be able to manufacture differently designed support frames, often of different lengths but also of different widths, for different slicer designs with lower bearing and logistics costs, they are assembled from—differently designable—lateral support modules on the one hand and transverse support modules of different lengths on the other, but the transverse support modules are only detachably connected to the lateral support modules, usually by bolting. These modules in turn can be composed of submodules, which in turn can be composed of individual elements, whereby connection to the entire modules can also be made by welding.

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.

Under control by a controller and without contact of the blade to the food product to be cut, the method comprises: a) moving the blade along the blade axis in an approach direction to approach the cutting frame until contact with the cutting frame, b) stopping the approach movement of the blade, and c) moving the blade back in a spacing direction by a distance corresponding to a desired size of the cutting gap, measured in a direction of the blade axis.

Abstract: In order to avoid that, in a spray unit for applying liquid or powdered anticaking agent between shingled or stacked slices, free-running supply lines to each individual nozzle in a contamination-intensive area of a slicing machine run freely and are also difficult to clean, the spray nozzles and shut-off valves, which are usually also provided for each nozzle, on the other hand, as well as corresponding sections of the supply lines, are protected and tightly arranged inside a hollow, pressure-tight spray bar which extends over all tracks of the slicing machine and is held at one end by means of a flexible and adjustable holding device and is supported relative to a base frame of the slicing machine.

Abstract: A transport unit, such as a feeder of a packaging device, is provided, wherein the loading of the transport unit by portions is registered by a control and stored in a memory of the control. The transport unit, in particular its operating unit, is designed in such a manner that an operator can select and mark food pieces or portions to be removed from the transport unit and actually removed, on a display of the operating unit where they are displayed in a run during operation of the transport unit, whereupon the control automatically deletes the food pieces or portions in its memory. For this purpose, the operator observes the transported food pieces or portions, preferably in reality, or on the display of the operating unit, and marks them as rejects, either by clicking on them with a cursor or touching them in the case of a touch-sensitive display.
