Abstract (en)

[origin: EP2947188A2] A front top roller (65b) is a delivery roller arranged in a drafting device (6) to deliver a sliver (S). The front top roller (65b) includes a roller body (92) and a property modified layer (94) formed on an outer peripheral surface of the roller body (92). The roller body (92) is made of a rubber composite of a type A durometer hardness in the range from 40 to 83. The property modified layer (94) is formed by modifying the rubber composite used for making the roller body (92) such that a microhardness of the property modified layer (94) is greater than that of the roller body (92) by a value in the range from 1 to 15.
