Seal facilitating holes (33, 34) are continuously punched in a continuously moving web (11) and side seams are formed by continuously sealing a continuous web (19, 23). The stand-up pouches (P) are positively opened by a continuous Coanda-Effect application or alternately by a combined vacuum/mechanical operation. Stand-up pouches (P) are continuously formed, filled and sealed without intermittent web stops for web or pouch operations.</p> |
