Title: Web transport load and unload system

Abstract: A tape loading system for use with tape transport systems having low inertia tape loops formed in vacuum buffer columns in a tape path between the tape storage reels and the tape driving means comprising, a vacuum source for providing vacuum in the vacuum buffer columns and ascertaining a predetermined value of build-up of vacuum in the columns and upon attaining the predetermined vacuum value supplying a predetermined length of tape from the tape storage reels to each of the buffer columns. A tape unloading arrangement also provides for automatically ensuring rewind, then shutting off the vacuum source, and then applying sufficient bias for slight rotation of the storage reels to unwind the tape.
