Method for producing a
honeycomb structure (40, 100) for fine
particle capture filters, wherein the
honeycomb structure (40, 100) comprises several porous
honeycomb structure segments (10, 50) connected to one another via binder material
layers (54), each porous
honeycomb structure segment (10, 50) comprising: partitions (52) made of a SiC material, the partitions (52) defining several cells (51) forming flow paths for a fluid, each of the cells (51) extending from an inlet surface, which is an end surface on the fluid inlet side, to a fluid outlet surface, which is an end surface on the fluid outlet side; and an outer circumferential wall (53) located at the outermost perimeter, wherein the method: the joining of each of the porous honeycomb segments (10, 50) via the binding material
layers (54) by applying a binding material between the connecting surfaces of each of the porous
honeycomb structure segments (10, 50) by means of a
nozzle section of a binding
material applicator, wherein the
nozzle section (60) of the binding
material applicator: a binding material inlet opening (61); a binding material outlet chamber (63) with a slot-shaped binding material outlet opening (64) for dispensing an introduced binding material; and a binding
material flow path (62) with a curved section through which the binding material passes from the binding material inlet opening (61) to the binding material outlet space (63) and wherein the binder
material flow path (62) of the
nozzle section (60) includes a buffer space (68, 69) which is designed such that a flow path cross-section expands stepwise in the direction of the binder material outlet space (63) on a downstream side of the curved section.
