Abstract

Reel winding roll that includes a core and an elastic surface layer positioned on the core. The roll also includes surface orifices formed on the elastic surface layer, air gathering spaces that are sealed at least in the circumferential direction, and channels arranged to couple the surface orifices to the air gathering spaces. The process includes guiding a moving web over a circumferential portion of the reel winding roll, and receiving, in the air gathering spaces, air entrained by the moving web. The entrained air is guided to the air gathering spaces through the surface orifices and the channels.
