PURPOSE:To obtain the correct unrolling of a textile in an unrolling machine for a rolled textile placed on an oblong work table to travel easily by feeding back the traveling distance of an unrolling machine main body for controlling servo-motors for an unrolling roller, and a letting-out roller. CONSTITUTION:In this unrolling machine, a long textile 7 mounted on a support base 6 on an unrolling machine main body 4 is drawn out by the rotation of an unrolling roll 9, and the unrolling machine main body 4 is made to travel along a rail 1a on a work table 1 via traveling wheels 5 for letting out the drawn out textile 7 on the work table 1. At this stage, the unrolling machine main body 4 is provided with a revolution sensor 55R in contact with the traveling rail 1a, and the traveling distance is calculated on the basis of the output thereof. This calculated value is respectively compared with output of revolution sensors 55K and 55F provided in drive servomotors 52K and 52F for the unrolling roller 9 and a letting-out roller 12, and servo-motors 52K and 52F are respectively controlled in accordance the compared results thereof. |
