Abstract
An exchangeable reinforcing element for pressure rollers of drafting units of spinning machines. The reinforcing element comprises a thin reinforcing tube and a flexible roller covering securely affixed thereto which can be slid onto the pressure roller base body. The reinforcing element is cut from a long tube body to the required effective width. The roller covering is turned down at both ends in such a way that the reinforcing tube projects laterally over the roller covering.
