Reclosable bags, apparatus and method

摘要: A method and apparatus are provided by which bag forming material is obtained feeding sheet (2) together with male female closure elements (5, 6) to a nip between guide roller (3) pressure rollers (9, 10) at adhesive applied from nozzles (11, 12). The resulting assembly fed drive means (14, 15)to an accumulator (16) on continuous basis then intermittently over shoulder (21) into tubular form (22) while maintaining the predetermined distance apart before such as grooves (19) in (18) locating positions facing each other downstream of shaping suitable (23) may include rotatable elements. drawn through transverse reciprocating sealing bars (26) pilfer proof can be vertical (25).
