As a result, an article with adhesive tapes can be manufactured in a stable manner at a good productivity without a skill of the operator. Also, according to the present invention, when a carrier low in bulk density and rich in softness is covered during a process for producing a catalytic converter for cleaning exhausted gas, it is possible to quickly and properly fix a mat on the outer circumference of the carrier while assuredly preventing the surface layer of the mat from being damaged caused by the application of the double-coated pressure sensitive adhesive tape.
