| 8 | Cutting carton blanks and cutters therefor | US944442 | 1986-12-19 | US4725261A | 1988-02-16 | Michael W. Millard; Henry L. Dunn, Jr. |
| Apparatus and method for cutting an end portion of a carton blank, e.g. to form a stitch flap, employs a rotatably driven male cutting head cooperating with a rotatably driven female cutting head. The female cutting head has a peripheral cutting groove therein and an anvil surface adjacent one side of the groove. The male cutting head has a two edged slot cutting blade of predetermined arcuate length which enters the groove each revolution, and a knife which extends transversely away from the blade and engages the anvil surface each revolution. The blade has a scallop-like cut-out in the side adjacent the anvil surface. The cut-out modifies the blade to a single edged cutting blade for a small part of its length. Scrap portions produced from the carton blank by a slotting cut of the blade and a transverse cut of the knife are integrally connected together by a bridging piece enabled by this cut-out. This integral piece of scrap is conveyed by the groove to a stripping blade and then drops onto a conveyor, so eliminating any uncontrolled portion of scrap. The groove can have radial side channels for more positively gripping strips of scrap engaged therein. | ||||||
| 9 | Method and apparatus for scoring plastic sheet material | US366058 | 1982-04-06 | US4415515A | 1983-11-15 | Benjamin Rosenberg |
| Plastic sheet material used for forming box blanks are provided with soft, bendable score lines by applying frictional heat through rapid vibration. The sheet material is clamped under high pressure between a resilient make-ready and a scoring tool, and is subjected to the vibratory action which generates frictional heat sufficient to melt the plastic material at the engaged interface, thereby forming a score line along which the sheet material may be bent to form an assembled box. A completed box blank may be formed in a single operational step, by cutting the box, impressing the score lines, and impressing embossments, if required, simultaneously in a single operational cycle of seconds duration. | ||||||
