<p>The channel (14) has a wide base (15). Rolls of adhesive (2) and paper (3) tape are carried on cylinders (20. 21), their rotation governed by mouldings (22. 23). The star wheel (13) rotates similarly. Narrow outlets (45. 202) offer to a nip area (44) between the housing (4) and star wheel (13). A tilt piece (28), spring (32) loaded, carries a knife (31). Downward movement (17) of a bag rotates the star wheel (13) nipping the tapes (2. 3) around its mouth in readiness for the upward arced movement of the knife (31). After severance, continued movement downward locates the bag in the widened channel (15) anticipating withdrawal outwards.</p> |
