  • Patent number: 8136434
    Abstract: A control device for a cutting blade, particularly for cutting-off machines for logs of web material, interrupts operation of the cutting blade when deformation of the blade reaches a preset deformation value and resumes operation of the cutting blade when the deformation of the blade is less than another preset deformation value. The control device includes a measuring device for measuring deformation values of at least a portion of the cutting blade, at least one comparator for comparing the measured deformation values with at least one preset deformation value set by an operator, and an actuator which sends, according to signals coming from the comparator, control signals to a motor of the machine to control the start up and/or the stop of the motor.

  • Publication number: 20100071522
    Abstract: A rotary blade for an interchangeable rotary cutter comprising perfectly spaced teeth. The rotary cutter and blade are passed over wearable fabric creating perfectly spaced slits in the fabric which are spaced far enough apart so that the fabric will not tear when pulled. The user can hand stitch ribbon, cord, heavy thread, yarn or other embellishment through the slits creating a decorative edge. The size and shape of the slits allows the user to hand stitch without having to tug on the needle. Slits created in multiple pieces of fabric allow the user to seam the pieces together using ribbon, cord, heavy thread, yarn or other embellishment creating a decorative seam.

  • Publication number: 20100043610
    Abstract: An ultrasonic trimming apparatus is composed of an articulated robot, a cutting apparatus, and a grindstone. The cutting apparatus is composed of an ultrasonic oscillator which is supported by the end portion of the articulated robot, a cutter blade which is supported by the ultrasonic oscillator, and a workpiece securing portion which secures a workpiece. The grindstone serving as a grinding member is disposed within the movable range of the cutter blade driven by the robot and is placed in a position at which the cutter blade can pressure contact the cutter blade. The cutter blade is ultrasonically vibrated by the ultrasonic oscillator and is ground while being pressed against the grindstone by means of the articulated robot.

  • Publication number: 20010049987
    Abstract: A sheet material cutting apparatus includes a cutting head and a knife frame rotatably coupled to the cutting head. A blade defining a cutting edge is coupled for reciprocation to the knife frame, as is a primary sharpener for sharpening substantially the entire cutting edge of the blade after it becomes dull from operation. A presser foot having a secondary sharpener mounted thereon, is also coupled to the knife frame for movement between a raised non-working and a lowered working position. The secondary sharpener includes a sharpening member engageable with the cutting edge of the blade via the action of an actuator, for sharpening a portion of the blade's cutting edge between primary sharpening operations.
