  • Patent number: 10828794
    Abstract: An automatic sizing cutting device includes a conveyance unit, a measuring device, a rotary cutter arranged downstream of the conveyance unit so as to oppose a band-shaped member and having a cutting blade on an outer circumferential surface thereof, a die roller which is arranged on a side of the band-shaped member opposite to the rotary cutter and which rotates in a direction opposite to a rotation direction of the rotary cutter; and an elastic member which urges the die roller toward the rotary cutter. The rotary cutter is controlled to rotate in accordance with a conveyed length of the band-shaped member measured by the measuring device, and is controlled such that circumferential speeds of the rotary cutter and the die roller when the cutting blade of the rotary cutter cuts the band-shaped member are equal to a conveying speed of the band-shaped member.
