    • A splice mechanism (100) for a packaging assembly (10), the packaging assembly (10) including: a former shoulder (12); a controller (14); a film drive (16) controlled by the controller (14) for feeding a film (112) at a film speed to the former shoulder (12) to form a tubular film (22) moving in a film direction (20); a sealing device (24) to seal the tubular film (22) in a first sealing direction (26), the first sealing direction (26) being parallel to the film direction (20); a set of jaws (28) controlled by the controller (14) and movable at a jaw speed to engage and seal the tubular film (22) in a second sealing direction (30) to form a first seal (32) and a second seal (34) in each bag, thereby forming a closed bag (36), the splice mechanism (100) including: an active film roll (110) from which film (112) is drawn to be fed to the former shoulder (12) by the film drive (16); a second film roll (120) having film (122) for feeding to the former shoulder (12); a film roll holder (130) holding the active film roll (110) and the second film roll (120) such that film (112) from the active film roll (110) extends along a film path (140) to the former shoulder (12) and the second film roll (120) is accessible; a splice roller (150) against which film (122) from the second film roll (120) is placed, the film (122) having a film end (124), the film end (124) having an adhesive (126), the splice roller (150) being movable between a free position, wherein the film path (140) is unimpeded by the splice roller (150), and a splice position, wherein the film path (140) is tangential to the splice roller (150) at a splice point (142) on the film path (140).

    • A rotary packaging machine 10 having rotatably driven stripper bars 17 and 18 that strip tubular bag material 36 prior to sealing of the bags being formed. To further inhibit material being located between the sealing jaws there is provided tube closer bars 28 and 29. The bar 28 has a longitudinally extending projection 34 that is received within a longitudinally extending recess 35 of the bar 29. The tubular bag material 36 by engagement within the recess 35 by the projection 34 laterally projects the bag material 36 and three longitudinally spaced locations 54.
    • 旋转包装机10具有可旋转驱动的剥离杆17和18,其在密封形成的袋之前剥离管状袋材料36。 为了进一步抑制位于密封爪之间的材料,设置有更靠近的管28和29.杆28具有纵向延伸的突出部34,该突出部34被容纳在杆29的纵向延伸的凹部35内。管状袋材料36通过接合 通过突出部34在凹部35内侧面地突出袋材料36和三个纵向间隔开的位置54。
