摘要： A take-out leading roll, spreader roll or equivalent for a web-like material including a non-revolving roll axle having end parts and a middle part situated between the end parts, and a continuous and tubular roll mantle revolvingly journalled by bearings on the roll axle and extending over the end parts and the middle part. The middle part is pivotally linked to the end parts to enable the roll to be bent to a desired arcuate shape. The roll mantle is preferably journalled on the roll axle only in the areas of the roll ends by bearings supported on the end parts of the roll axle. The material of the roll mantle is preferably a composite material.
