  • Sheet material conveying apparatus
    Patent number: 8844176
    Abstract: A conveying apparatus includes a first roller that is rotational to convey a nonwoven fabric and a second roller that is rotational to convey the nonwoven fabric and is located on the trailing side of the first roller with respect to the conveying direction of the nonwoven fabric. The conveying apparatus includes a noncontact sensor and a controller. The noncontact sensor detects the distance from the nonwoven fabric at a position between the first roller and the second roller. The controller uses the distance detected by the sensor to compute the slack amount of the nonwoven fabric and controls the rotation speed of the second roller, thereby reducing the difference between the computed slack amount and a predetermined target value.
