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.

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.

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.
