Abstract: A chamfer cutting device for cuffing packaging materials comprises a die and a knife part which has a plurality of knives. The die can be moved toward the knife part in order to carry out a cut. The knives are arranged individually in the knife part in a force-dependent manner in such a way that their position with respect to the tool plate varies in a defined way as a function of the force produced by contact with the packaging material or the die. In the event of contact between the knife and the die, a force acts on the knife which does not exceed a predefined maximum force. The chamfer cutting device has the advantage that the die can be guided right up to the knives.

Abstract: A machine for cutting the border of a workpiece using one or more water jet cutting tools separately carried by one or more monorail track mounted carriage assemblies is disclosed. The machine can also include an aperture forming apparatus for forming circular openings and/or elongated slots in the workpiece prior to/or simultaneously with the border trimming operation, all while the workpiece occupies a single work station in the machine. In one embodiment, the aperture forming apparatus features a cutting tool mounted on an elongate arm affixed to and extending from a plate which is fixedly oriented in a horizontal plane. While so oriented, a motor and gear assembly causes the plate to wobble in a circular pattern in the plane to, in turn, cause the tool to make a circular cut in the workpiece. In another embodiment of the apparatus, a motor rotates a cam carried on a free end of a stationary arm, the cam containing an eccentrically mounted cutting tool.

Abstract: An optical recording medium-manufacturing apparatus which is capable of reducing wear of a cut-forming blade section used for forming a cut in a resin layer, without increasing the component costs of the apparatus. An ultrasonic horn includes a hollow-cylindrical cut-forming blade section for being pushed into a resin layer formed on one side of a disk-shaped substrate, thereby forming a circular cut in the resin layer. A control section controls motion of the ultrasonic horn caused by a moving mechanism. The control section causes the ultrasonic horn to be pushed in to the resin layer while causing ultrasonic vibration thereof to thereby form the cut, and while maintaining a state of ultrasonic vibration of the abutment section and a pushed-in state of the cut-forming blade section, causes the punching blade section to be pushed into the disk-shaped substrate, to form the central hole.
