ABSTRACT:
Apparatus which winds a running web onto a driven takeup reel employs a distancing roller which is spaced apart from the outermost convolution of growing roll on the reel and is moved away from the reel at a rate which is proportional to the rate of growth of the roll so that its spacing from the outermost convolution of the roll remains unchanged. A suction generating device is provided to evacuate air from a substantially gusset-shaped space which is defined by the outermost convolution of the growing roll and the web portion which advances from the distancing roller to the roll. This reduces the likelihood of entrapment of air between neighboring convolutions of the roll on the takeup reel. The likelihood of entrapment of air is further reduced by wiping air off one side of the web in the region of the distancing roller, by wiping air from the outer side of the outermost convolution of the roll upstream of the gusset-shaped space, and/or by causing a roller to bear against the outer side of the web immediately downstream of the locus where successive increments of the running web reach the roll.
