Title:
WINDING METHOD FOR HONEY COMB BODY
Document Type and Number:
Japanese Patent JPH08257361
Kind Code:
A
Abstract:

PURPOSE: To provide a highly reliable metal support without joining failure even in the case the thickness of foils is made thin by making the contact plane pressure of both flat and corrugated foils optimum in whole range from the center part to the outer circumferential part of a honey comb body at the time when the flat foil and the corrugated foil are layered and wound in a manufacturing method of a honey comb body made of a metal to be employed as a carrier for an exhaust gas purifying catalyst for various kinds of internal combustion engines.

CONSTITUTION: Three or more rolls 5 are installed in the circumferential direction of an outer circumference face of a honey comb body 1, the honey comb body 1 is pinched and pressurized by the rolls 5, and while back tension being applied to a flat foil 2, winding of foils is carried out. It is preferable to drive at least three installed rolls 5 and it is more preferable to adjust the roll pressurizing force corresponding to the diameter of the honey comb body 1 during winding. Consequently, the quality of an obtained metal carrier can be stabilized and improved and an exhaust gas purifying function at an engine starting initial stage is improved and gas discharge resistance is lowered by using the obtained thin foil metal carrier.
