Abstract
An article of manufacture has a web wound on a cylindrical hub and a web leader wound between the hub and the web. The web leader is stiffer than the web and has a first end at the hub. A first leader portion has a uniform thickness greater than the thickness of the web and extends from the first end to a second leader portion. The second leader portion tapers from the uniform thickness at the first leader portion to a reduced thickness at a second end which is attached to the web. The tapering second leader portion overlays the first end of the web leader, whereby the web leader between the hub and the web constitutes a cylindrical support for the wound web. The disclosure extends to methods and articles for facilitating the winding of the web on a cylindrical hub, employing the above mentioned web leader.
