摘要： Rolls of individual plastic bags are formed on apparatus that overlaps the bags before the bags are fed into the roll to provide a compact roll of individual bags. The apparatus overlaps portions of the bags so that a plurality of bags can be continuously fed into the roll even though the bags are not mechanically connected end-to-end to adjacent bags on the roll.

摘要： According to the present disclosure, tubular thermoplastic material is intermittently fed between opposed transversely extending seal bars operating in timed relation with the intermittent feeding of the web to sequentially perform cutting and sealing of the web during its period of repose. To insure a clean straight transverse cut, which occurs momentarily before transverse sealing, the web is held under tension between longitudinally spaced draw and feed rolls. Immediately after the web is transversely severed, the seal bars are brought into pressure engagement transversely sealing the web along a margin which will define the bottom of the bag. Before the web is fed an additional increment, it is momentarily fed rearwardly to avoid the possibility of adherence to the seal bars.
摘要翻译： 根据本公开，提供了一种方法，其中管状热塑性材料被间歇地供给在相对的横向延伸的密封条之间，所述相对的横向延伸的密封条以与所述幅材的间歇进给相关的方式操作，以在其布置期间顺序地执行所述幅材的切割和密封。 为了确保在横向密封之前立即发生的干净的直横切割，将幅材保持在纵向间隔的牵伸辊和进料辊之间的张力下。 在腹板被横向切断之后，密封条紧紧地沿着将限定袋底部的边缘横向地密封纤维网。 当腹板的密封部分位于密封站时，冷却空气沿腹板的密封部分排出以进行冷却。 在纸幅进给一个额外的增量之前，它被瞬间向后进给，以避免粘附到密封条的可能性。

摘要： A folding apparatus of a bag-making machine includes a plurality of folding mechanisms each having a pair of nip rollers which receive a sheet or bag from an associated carrier structure, to thereby sequentially form transverse folds in each sheet or bag. In order to abate lamination-like adhesion of relatively thin, light gauge film materials to the belts and other surfaces of the folding apparatus, the belts and/or guide rollers of the apparatus are preferably provided with grooved sheet-contacting surfaces. The apparatus is additionally configured to abate wrinkling or buckling of a leading edge portion of each sheet or bag which can occur attendant to its reversal in direction of movement as it is directed between the nip rollers of each folding mechanism. High-speed operation is facilitated while avoiding improperly folded bags, or equipment jamming.

摘要： Disclosed is a rotary vacuum arm bag or sheet transferring and stacking device and a stack-handling system enabling an indexing of counted bag stacks. The transferring device grasps and retains the bags adjacent margins transverse to the direction of web advance while at least a portion of the opposed margins parallel to such directions are spaced inwardly from the arms to define a slot or gap thru which stack-retaining fingers project contributing to remove a bag from a pair of arms and retaining the bag in a stack wherein respective margins overlie each other. Also disclosed is a stack-handling system having the ability to remove a completed stack from the stacking station and yet allow, if desired, continuous bag machine operation and, as a result, uninterrupted transfer of sheets or bags to the stacking stations.

摘要： A process for making an internally-reinforced bag assembly includes formation of an outer bag body with a plurality of longitudinally oriented, laterally spaced pleats or tucks therein. An inner reinforcement layer is applied to the outer bag body after formation of the pleats, whereby the inner layer spans and overlaps each of the pleats. An apparatus embodying the present invention effects bag formation in this fashion. Advancement through the forming apparatus effects formation of the outer web into a gusseted tube, and formation of a square bottom seal. The completed bag assembly includes the inner reinforcement layer, which is dimensioned to define a circumference which is less than a circumference defined by the bag body. The resultant bag assembly resists bulging and deformation under the influence of particulate, granular, or other flowable products packaged therein.
