Title:
METHOD OF MANUFACTURING HONEYCOMB STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2007/141958
Kind Code:
A1
Abstract:
A method of manufacturing a honeycomb structure, in which a honeycomb structure manufactured
by superposing a corrugated sheet and a flat sheet over each other and rolling
up the resultant is press fitted into a container and reliably held in position
without deformation. In the method of manufacturing a honeycomb structure prepared
by superposing a corrugated sheet and a flat sheet over each other and rolling
up the resultant in a spiral form, a portion near the leading edge of the rolling,
which leading edge is the edge on the outer peripheral side of both the corrugated
plate and flat plate of the honeycomb structure, is pulled in the longitudinal
direction corresponding to the direction of the rolling. As a result, the honeycomb
structure is formed such that the closer to the leading edge of the rolling, the
greater the pitch of the corrugations, and this in turn results that the closer
to the leading edge of the rolling, the lower the height of the corrugations.
