ABSTRACT:
Apparatus for winding web material, such as a paper web, on a tubular core to obtain a web roll includes a first carrier roll forming a first nip with the web roll, a second carrier roll forming a second nip with the web roll, at least one of the first and second carrier rolls being driven to rotate the tubular core and web roll being wound thereon, and a weight roll acting on the web roll with a press force. The first and second carrier rolls and weight roll are arranged asymmetrically with respect to each other such that the weight of the web roll acts on the second nip and the tension of the web material being wound is determined by the magnitude of the component of the press force applied by the weight roll acting on the first nip. The web material is disposed to run onto the core tube through a space between the first and second carrier rolls and through the first nip.
