摘要：
Provided is an initial crack formation device (1) for scoring a front-side end (Ga) in a conveyance direction (B) of a glass ribbon (G) conveyed by a belt conveyer (3) so as to form an initial crack group (CG) including a plurality of aggregated initial cracks (C) in a width direction of the front-side end (Ga) orthogonal to the conveyance direction (B). The initial crack formation device (1) includes a flap wheel (4) for scoring the front-side end (Ga) while rotating in a direction of drawing the glass ribbon (G) into the conveyance direction (B). The flap wheel (4) is configured to rotate at a rotational peripheral speed higher than a conveyance speed of the glass ribbon (G).
