Реферат: ABSTRACT A cutter and cutting method for cutting synthetic resin sheets or ribbons in a manner that avoids the forma-tion of particulates from the cutting operation are dis-closed. The cutter includes a blade and associated sheet holding structure for creating a sharp bend in the sheet. The sharp bend creates a zone of high stress in the sheet. An element for rapidly heating the sheet is brought near the edge of the blade where the fold in the sheet exists. The localized stress in the fold cause the sheet to rup-ture along the fold after the sheet has been heated to a sufficient extent.
