    • A split bag making machine includes a first primary split draw roller and a second primary split draw roller, each having first and second web contacting sections which are independently rotatable, the first section of the first primary split draw roller being in rolling engagement with the first section of the second primary split draw roller at a first nip, the second section of the first primary split draw roller being in rolling engagement with the second section of the second primary split draw roller at a second nip. A first servo motor is coupled to the first web contacting section of the first primary split draw roller, and a second servo motor is coupled to the second web contacting section of the first primary split draw roller. The respective rotational speeds of the first and second servo motors are controlled by a controller. The split bag making machine also includes a secondary split draw roller positioned upstream of the primary split draw rollers, the secondary split draw roller having a first web contacting section corresponding to the first web contacting sections of the primary split draw rollers and having a second web contacting section corresponding to the second web contacting sections of the primary split draw rollers. The webs are driven by the secondary split draw roller at the upstream end of the synchronization section, and driven by the primary split draw rollers at the downstream end of the synchronization section.
    • 分体式制袋机包括第一主分割牵引辊和第二主分割牵引辊,每个第一主分割牵引辊具有可独立旋转的第一和第二腹板接触部分,第一主分割牵引辊的第一部分与第一主分割牵引辊滚动接合 所述第二主分割牵引辊的第一部分在第一压合部处,所述第一主分割牵引辊的第二部分在第二压区处与所述第二主分割牵引辊的第二部分滚动接合。 第一伺服电动机联接到第一主分割牵引辊的第一卷筒纸接触部分,并且第二伺服电动机联接到第一主分割牵引辊的第二卷筒纸接触部分。 第一和第二伺服电动机的相应转速由控制器控制。 分裂制袋机还包括位于主分割牵引辊上游的次级分离拉伸辊,次级分离拉伸辊具有对应于主分割拉伸辊的第一卷材接触部分的第一卷材接触部分,并且具有第二网 接触部分对应于主分割牵引辊的第二卷筒纸接触部分。 腹板由同步部分的上游端的二次分割牵引辊驱动,并由同步部分的下游端的主分割牵引辊驱动。
