ブ引出し搬送装置。[Claims for Utility Model Registration] (1) At least one of a pair of pinch rollers disposed at regular intervals on the circumferential surface of the web conveyance drive roller presses the circumferential surface of the conveyance drive roller with a biasing force within a specific range. The web is carried in from a side closer to the pinch roller than the direction of the cut line between the conveyance drive roller and the other pinch roller, or A web pull-out and conveying device is configured to apply a conveying force to the web so that the web is conveyed in a direction closer to the pinch roller than the cutting line, and the radius of the conveying drive roller is rmm, and the conveying drive roller has a radius of rmm. When the angle between the circumferential surface of and the circumferential surfaces of the pair of pinch rollers relative to the axis of the transport drive roller, that is, the web hugging angle is θ, the relationship between r and θ is cos −1 r -3r≦θ≦90°. (2) In claim 1, instead of one of the pinch rollers, a tension roller is provided so as to urge downward without contacting the conveyance drive roller, and the web holding angle in a steady state is set to θ. Characteristic web drawer conveyance device.
