    摘要： A pouch making machine which simultaneously creates perimeter seams for a plurality of pouches on a web and temporarily stores the seamed web in an accumulator at the conclusion of the seaming step, and then withdraws the web from the accumulator to sever the individual pouches from the web. The individual pouches are severed from the web by a cutoff knife that is moving at the same velocity as the web during the cut. The withdrawal of the web from the accumulator is carried on independent of the seaming step, except that regulating means is included to make the long term average web speed the same through the seaming step as through the cutoff step.

    摘要： An arrangement in a bag-making machine for forming bag-defining lines of perforation and weld lines in an elongate web (7) comprises a driven roller nip including a nip roller (4) and a backup roller (5), by means of which the web (7) is fed through the machine (1), an elongate cutter (10) which is parallel to the rollers (4, 5) and rotatable about its longitudinal axis, and which when rotated is moved into engagement with the back-up roller (5) for making the lines of perforation, and two welding units (8) with sealing jaws (22) for making the weld lines. In order to allow optional adjustement of the spacing between consecutive lines of perforation and weld lines, the cutter (10) is separately connectible and disconnectible independently of the operation of the roller nip (4, 5) or of other drive means in the machine (1). The cutter (10) and the welding units (8) and driven by quick-acting step couplings for stepwise rotation of the cutter (10) through predetermined angles and for stepwise displacement of the sealing jaws (22). An angle sensor measuring the web length fed to the machine (1) controls the rotation of the cutter (10).

    摘要： A method and apparatus for making bags from a thin thermoplastic material supplied as either a flat tube or a double-folded web to an advancing supporting path such as the common opposite flights of two sets of endless conveyors, thereby applying the loop-system principle, the supporting conveyors clamping the material at spaced intervals with two sets of clamping beams, lying close to each other, a separate set of cooperating sealing beams cooperating with the thermoplastic material for making the seals within the space between both sets of clamping beams.
