ABSTRACT:
A vacuum/blowing sheave on the end of the lower calender roll of a papermaking machine threads a tissue web tail from a Yankee dryer to a take-up reel through the calender. The sheave is positioned adjacent to the outlet of the threader tube from the Yankee dryer, where the vacuum portion of the sheave picks up the tail and transports it towards the take-up reel. Upon transiting the closed nip of the calender, the tail is blown by a short blowing section on the sheave into the tube threader which leads to the take-up reel.
