FIELD: mechanical testing. SUBSTANCE: sample made in the form of strap 1 is placed between rollers 2 and 3, and is then moved and rolled. Loading by rolling is effected with the aid of conveying rollers 2 and 3 and loading parameters are determined proceeding from position of rollers relative to rolling plane. In the process of rolling stress-strain state is specified by shape of rollers and their positioning. EFFECT: higher accuracy of testing materials intended for manufacturing parts by winding. 4 dwg
