Abstract: To restrain shifting of a circular blade, and reduce a cutting-in angle of the circular blade with respect to the tape roll main body, both ends of a rotatable blade shaft 38 is supported by a pair of shaft bearings 39a and 39b of shaft supporting members 37 of a tool post 20. The circular blade 21 is mounted to the blade shaft 38, between the shaft bearings 39a and 39b. This prevents the blade shaft 38 from being shifted or bent, restrains shifting of the circular blade 21, and reduce the cutting-in angle of the circular blade 21 with respect to the tape roll main body.

Abstract: The present invention provides a thermosetting adhesive or pressure-sensitive adhesive tape or sheet including: a thermosetting adhesive or pressure-sensitive adhesive layer formed of a thermosetting adhesive or pressure-sensitive adhesive composition containing an acrylic polymer (X) constituted of, as essential monomer components, an alkyl (meth)acrylate (a) in which the alkyl moiety thereof has from 2 to 14 carbon atoms and a cyano group-containing monomer (b), and a phenol resin (Y); and provided on at least one surface of the thermosetting adhesive or pressure-sensitive adhesive layer, a release liner including a plastic film substrate and a release layer provided on at least one side of the plastic film substrate, the release layer containing low density polyethylene as a major component and having a thickness of 5 ?m or more and less than 20 ?m.

Abstract: The laminate-cutting method according to the present invention is a method for cutting an optical film wherein layers are laminated through a pressure-sensitive adhesive agent with a cutting edge, wherein the cutting of the laminate with the cutting edge is performed in the state that compressive stress applied to the optical film is decreased when the laminate is cut with the cutting edge. This makes it possible to provide a laminate-cutting method, a cutting device and a laminate-cutting pedestal wherein the generation of the adhesion of paste to a cutting edge, the blocking, cracking, chipping of cut faces, and others is prevented.
