1. A method of producing honeycomb, the method comprising:
stacking sheets of metal film in an areal relationship upon each other in a transverse direction transverse to a longitudinal direction of the sheets;
connecting the sheets, via a plurality of connecting regions, by bonding in the transverse direction to form a block, the plurality of connecting regions connecting the sheets together in a portion-wise manner by bonding in the transverse direction, the connecting regions being arranged at regular spacings along the longitudinal direction;
expanding the block in the transverse direction to form honeycomb cells with cavities between the sheets; and
dividing the block into a plurality of individual honeycombs by cutting substantially along separation planes parallel to a longitudinal direction/transverse direction plane,
wherein, with respect to three successive sheets, the connecting regions which connect first and second sheets are arranged with offsets along the longitudinal direction relative to the connecting regions which connect second and third sheets, wherein an offset along a first side of the longitudinal direction is unequal to an offset along a second side of the longitudinal direction, wherein, with respect to the three successive sheets, said offsets are always smaller along the first side of the longitudinal direction.
