The A-B cut develops two negative bands, at which every scenes are cut in alternately A or B band and the following scenes are set in full-length with black film.
The splice lies always in black film, however, it changes once from head-cut (Kopfschnitt) to foot-cut (Fußschnitt). It must be taken into account that the splice still appears like film stripe that divides between two frames. Hence, the cleaver must be adjusted to respective cameras.

When both splice position "head-cut and foot-cut" exactly lie one upon another, the splice must appear like orange bar.

The head-cut:
                The Hammann Film Cleaver 16mm Mk."V"
                Wedge cut: 1,05mm / DIN-A
                Pins in front, is the cutting device for head-cut.

The negative, emulsion side up, on the "Schicht" plane of the cleaver are cut at the upper part of the frame. On the left side of the open splicer, put the film, emulsion side up.

The black film, emulsion side down, on the "Blank" plane of the cleaver get its first cut and will be applied with film cement. Emulsion side up, put the black film on the right side of the splicer then close.

The foot-cut :
                The Hammann Film Cleaver 16mm Mk."V"
                Wedge cut: 1,05mm / DIN- "A-B"
                Pins on the rear is the cutting device for foot-cut.

The negative, emulsion side up, on the "Schicht" plane of the cleaver are cut at the lower part of the frame. On the right side of the open splicer, put the film emulsion side up.

The black film are cut, emulsion side down, on the "Blank" plane of the cleaver. Applied with film cement, put it on the left side of the splicer then close.

With these procedures, youll surely get the right A-B cut and a satisfying result of invisible joins.
