  • Patent number: 11338459
    Abstract: A clipper blade protector enabling a user to enclose and protect the blades and teeth of clipper devices by incorporating a sheath body, a volume of cushion material, and a blade-receiving concavity. The sheath body extends between a cover end and an opening, wherein the blade-receiving cavity is formed within the sheath body between the opening and the cover end. The volume of cushion material is externally distributed along the sheath body between the cover end and the opening, thereby cushioning any external impacts against the enclosed portion of the clipper device. This protection is proposed to prevent breakage of the blades and teeth of the clipper device, saving both time and money in avoided replacements costs and maintenance.

  • Patent number: 11312035
    Abstract: Provided are a cutting device and method. A blade receiving portion crossing a cord-embedded rubber sheet member is disposed in one surface side in a thickness direction of the rubber sheet member placed in a conveying mechanism. A cutting blade disposed in the other surface side is held by a holder that rotates about a turning shaft extending in the thickness direction of the rubber sheet member. In a state where a cutting-edge advancement direction turns about the turning shaft, a turning restoring force that restores the cutting-edge advancement direction to a preset moving direction is constantly applied by a turning restoring mechanism to the holder before cutting the rubber sheet member. The rubber sheet member is sandwiched in the thickness direction by the cutting blade and the blade receiving portion, and the cutting blade is moved in the extension direction of cords to cut between the cords.

  • Patent number: 11298850
    Abstract: A controller of a cutting apparatus specifies a target position of an attaching portion in a fifth direction and controls a second moving mechanism to move the attaching portion in a third direction. If the controller determines that the attaching portion has reached the target position, the controller executes cutting processing based on the obtained cutting data by controlling the second moving mechanism based on a pressure corresponding value achieved when the attaching portion is located at the target portion. If the controller determines that the pressure corresponding value has reached a pressure threshold, the controller executes the cutting processing by controlling the second moving mechanism based on the pressure corresponding value achieved when the attaching portion is located at a first particular position where the pressure corresponding value is equal to or lower than the pressure threshold value. The controller restarts controlling the second moving mechanism.
