A spreader roll for webs of textile material has a flexible shaft whose end portions rotate in or with pairs of bearings installed in sleeves which are pivotable about horizontal axes to thereby change the curvature of the shaft and/or slidable with respect to stationary holders to thereby effect or change lateral deflection of the shaft. The shaft is surrounded by and fixed to annular supporting elements which are surrounded by an elastic hose whose ends are sealed against entry of atmospheric air.
