METHOD FOR CUTTING SHEET-LIKE MEMBER, MAT, METHOD FOR PRODUCTION OF EXHAUST GAS-PURIFYING DEVICE, AND EXHAUST GAS-PURIFYING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a cutting method capable of producing a mat for an exhaust gas-purifying device which can minimize damage to the sheet-like member such as a holding seal material, a foamable cushioning material or the like. ! SOLUTION: A cutting method comprises: a vertical cutting process of completely cutting a sheet-like member 100 in a direction parallel to the width direction of the sheet-like member 100 and in the direction inclined to the thickness direction of the sheet-like member 100 using a vertical cutting member disposed at the upside of a conveyor to form a vertical cutting part 30; and a lateral cutting process of contacting a plurality of lateral cutting members with the sheet-like member 100 using a plurality of lateral cutting members disposed at the upside of the conveyor along a direction perpendicular to the moving direction of the sheet-like member 100 and of cutting the sheet-like member 100 in a direction parallel to the moving direction to form a plurality of late
