For mounting and dismantling a resilient liner of a pressing roller of a draft-frame in textile machinery preparatory to spinning, a method is suggested which comprises the steps of positioning the liner on a temporary supporting member, inserting the roller into the liner with a snug fit while simultaneously slipping the temporary supporting member away. The worn out liner can be removed by cutting it longitudinally on at least two parallel lines by means of radially projecting blades mounted on a specially provided collar, the cut liner being then manually peeled off. An apparatus for performing these operations quickly and conveniently is also described. The method and apparatus in question permit to dispense with adhesives for fastening the resilient sleeve to its own supporting member, and affords the possibility of removing the resilient layer without damaging the roller in any wise.
