Honeycomb filter, its manufacturing, exhaust gas purification system, die for forming said honeycomb

摘要

A honeycomb structure (1) has partition walls (2x) arranged in X-direction to form cells (3) extending to other-end portion (44) from one-end portion (42) through axial direction; and partition walls intersecting with the partition walls, in which intersecting portion (6) of the partition walls include a lacking intersecting portion in the one-end portion. Independent claims are also included for: (1) a method of manufacturing honeycomb structure comprising processing/removing intersecting portions of partition walls in one-end portion of honeycomb body comprising the partition walls arranged to form cells; and (2) a die for forming comprising die base including >=2 surfaces and having raw material supply path that is opened in a surface and slits that communicate with the path and is opened in the other surface.
