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.

Automatic sizing cutting device

To provide an electric slide fastener system that can operate appropriately according to a state of an electric slider. An electric slide fastener system includes a slide fastener chain that includes a pair of fastener tapes and element rows including a plurality of elements fixed to the respective fastener tapes, a slider that moves with respect to the slide fastener chain, a power supply that supplies power for the slider to move with respect to the slide fastener chain, and a driving part to which the power is supplied from the power supply and that moves the slider with respect to the slide fastener chain. The elements pass through the slider to open or close the element rows. The slider is powered from outside.
