Abstract: A web-spooling apparatus for winding a thin web on a core is constructed to control any tendency of the web to telescope. A drive roller rides on the periphery of the web as it winds the web on the core. The drive roller includes web-penetrating radial spikes and has a pair of flanges at the top and bottom which extend radially beyond the spikes and contact the edges of the web should the web tend to move axially off the core. The core is mounted on a spindle in such a way as to permit the core to yaw about the spindle. Contact between the web and a flange causes the core to be yawed about the spindle and thereby provides an angle of small magnitude between the core and web, thus causing the web to move axially in a direction opposite to its first such action, thereby tending to correct the telescoping condition.
