Abstract: A stretcher roller for spreading out moving flexible strip material such as for example plastics film, paper or textiles, has a cylindrical outer surface of elastomeric material, with inclined incisions which are separated from one another by webs. The transition from the surface into an incision which makes an included angle of less than 90.degree. is of rounded or chamfered form.
