ABSTRACT:
A winding apparatus for a web, such as photographic film, advances the web through a cutting mechanism and along a fixed guide to a spool. After the end of the web is attached to the spool, the spool is rotated to wind convolutions of the web onto the spool. The spool is rotated in a direction which causes the web to move away from fixed guide due to the increase in the diameter of the web on the spool as each convolution of the web is wound onto the spool. Air under pressure is directed from an air bar against the web to locate the portion of the web adjacent the cutting mechanism in a position where it is not scratched by the cutting mechanism as it is wound onto the spool. The air bar also urges the web toward the fixed guide when the leading end of the web is advanced from the cutting mechanism into the space between the air bar and the fixed guide as it is driven to the spool for initial attachment to the spool.
