ABSTRACT:
Apparatus for feeding banding tape (22) from a tape spool mounted in a tray (27) to a station where a stack is wrapped by the tape, comprises a tape feeder (30) including a feed head (29) terminating in a tape guide (32, 33) which is movable between a first position (30) spaced from the stack and a second position (30') in which the tape guide is adjacent the stack. The tape path length from tape pinch means (28, upstream of the feed head) to the stack is longer for the first feed head position than for the second feed head position (30'). The tape end is clamped next to the stack with the tape feed head in its second position; the feed head is then withdrawn to its first position prior to rotation of the stack to form the band. A tape cutter then cuts the tape downstream of the feed head, and the feed head is thereafter moved to its second position, the tape being pulled back through the feed head until the cut end is flush with the end of the tape guide against the stack.
