Cutting tool
摘要:
A cutting tool for material, such as a web, sheet, slab, packaging or other material includes a dynamic guide slot in which the material is moved while it is bent by cooperative surfaces to stiffen the material and to direct the stiffened material into engagement with a blade for cutting the material. A pointed beak can pierce the material to initiate a cutting operation.
