ABSTRACT:
Apparatus for threading the leader of a flexible web through a coating, drying or other processing machine has an elongated steel strip which is adjacent the path of movement of the web through the machine and one side of which is overlapped by an inflatable hose. The leader of the web is separably coupled to a follower by a wire or cord, and the follower tracks the strip and simultaneously overlies and deflates a portion of the hose. The hose is connected with a source of compressed air, at least at one side of the follower, so that when the source admits compressed air into the hose, the latter is inflated and propels the follower along the strip. The follower has a smooth-surfaced slightly convex first roll which overlies and deforms the adjacent portion of the hose, and a flanged second roll which engages the strip opposite the hose so that the strip and the hose are located between the two rolls.
