In order to maintain required average weight of an entire batch when slicing a loaf into slices and yet avoid underweighting individual slices, different reference weights are selected for critical areas depending on basic shape of the loaf, usually the two ends, than for the remaining area.

In order to avoid underweight of slices when slicing a loaf into slices, thickness adjustments specified for slicing are adjusted depending on different pre-known parameters, from loaf to loaf and/or from slice to slice within one and the same loaf, preferably also across the boundary between two loaves optimized as early as possible so that existing weight conditions with regard to actual weight of the slices are maintained, in particular no more underweight slices are produced and/or the minimum average weight of the slices required for the entire batch is maintained.

A knife holder has a base and a knife support portion extending from the base. The knife support portion includes a distal edge and a knife support surface for supporting a knife. The knife support surface includes a shaped portion and a relieved surface. The shaped portion has a wavy shape and is located adjacent the distal edge. The relieved surface does not have a wavy shape and is located on the knife support surface so that at least part of the shaped portion is between the relieved surface and the distal edge. An abutment surface is between the base and the relieved surface and is defined by the relieved surface.

Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.

A packaging machine having a plurality of working stations for processing a film, at least one of the working stations being a cutting station. The working stations are disposed successively along a working direction and the film is conveyed in the working direction from a first one of the working stations to a second one of the working stations. The cutting station is configured to sever the film in a cutting direction, which is oriented transverse, preferably orthogonal, with respect to the working direction. The cutting station has a knife and counter pressure device, both being pressable against one another in a pressing direction. The disclosure is characterized in that the counter pressure device has a curved surface, which is curved around a curvature axis, and the counter pressure device is configured to roll on a cutting edge of the knife about a rolling axis with the curved surface.
