ABSTRACT:
A tube-tape-forming apparatus having a tube-forming base (1, 41) with a half-fold means (5, 46) on a feed end (2, 42), a full-fold means (7, 48) on a cut-off end (3, 43) and a transition-fold means (6, 47) intermediate the half-fold means and the full-fold means. .The half-fold means are guides (8, 11, 14, 15, 49, 52) which fold single-side-adhesion tape (26) in half linearly with nonadhesive sides (30) in contact. The transition-fold means brings opposite sides of folded tape towards each other selectively to form variously loop-folding with overlap of sides of the tape. The full-fold means are guides (19, 21, 23, 71, 88) which press the overlapped sides of the folded tape together in adhesive relationship to form variously circumferential (31) or flattened (32) linear-seam tube tape that can be used in flattened form or hand-inflated to be used in tubular form. The transition-fold means and the guides can be provided with rollers (33, 91). A tape dispenser (27, 92) at the feed end and a cut-off blade (25, 95) at the cut-off end can be provided in accordance with use conditions.
