ABSTRACT:
Apparatus for automatically threading the leading end of a web spooled on a reel into one end of a conveying passage includes a draw-out lever having a web support surface and movable to a first position at which the support surface engages the web spooled on the reel. A nipping finger is provided which is actuatable to trap the leading end of the web against the surface when the lever is in its first position. The lever is movable to a second position at which the support surface is spaced from the web spooled on the reel for unspooling the web from the reel. A feed mechanism is made effective after the lever is moved to its second position, and after the nipping finger has been deactuated, for engaging the unspooled web and feeding the leading end thereof into the conveying passage.
