A winding apparatus has a rotary element, such as a core, that is rotatable about a winding axis. A roller is disposed adjoining the rotary element. The roller and rotary element together define a nip. A guide shoe has a chute wall and a plenum. The chute wall is aligned with the nip. The chute wall has an inner end disposed between the roller and the rotary element and an outer end spaced from the roller. The chute wall has a plurality of bores communicating with the plenum. In use, gas blown through the bores propels a web to the nip in a fluid film. The free end of the web is guided from an outfeed end of the nip in a loop to a second position adjoining the inner end of the guide shoe. During the guiding, the rotary element is rotated against the loop. This continues until the web overlaps and is cinched.
