Abstract: A bag forming apparatus for forming a flat bottom of a bag includes a base, opposing sidewalls that extend upright relative to the base, and a top that is operably coupled to an upper portion of each of the sidewalls. The top has an intermediate pivot axis between the sidewalls that enables the top to pivot about the pivot axis between a collapsed state and an expanded state. In the collapsed state, the upper portions of the respective sidewalls are closer together and the top extends upright relative to the base to form a tip for insertion into an opening of the bag. In the expanded state, the upper portions of the respective sidewalls are spaced further apart and the top extends horizontally relative to the base to form a platform for forming the flat bottom of the bag.

Abstract: A method for manufacturing flexible bags, including: a first strip of flexible material is unwound as a continuous sheet in a longitudinal direction; a hem is formed on each edge of the first strip and the hems are glued over at least one length of a first or a second flap on one stitching face; a fold is formed in the first strip along a transverse folding line to fold down the first flap over the second flap against an internal face of the first strip, the fold bringing, for each edge, hem against hem so as to obtain the bonding of the hems, the strip is cut along a transverse section to form the bag at the end of the operations. Machine implementing the method and bag thus obtained.

Abstract: A container (100) is formed by being folded and sealed on one of a multiplicity of male dies (12) of an apparatus (10). The male die (12) with the container (100) placed thereon is inserted into a female die (120). The female die (120) retains the container (100) while the male die (12) is removed therefrom. Lips (110-112) of the container (100) are sandwiched against the female die (120) while product is pushed thereon to prevent collapse of the container (100). The multiplicity of male dies (12) are relatively moveable by rotating about an axis (20) relative to the female die (120).

Abstract: A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a low force extension.

Abstract: A bag making apparatus includes an intermittent feed device for feeding sheet panels, an adjustment device for detecting upper and lower thresholds for a length of the sheet panels included in a section from a first drive roller pair to a second drive roller pair, a movement device for moving a processing device and a sensor together as a movable group in the longitudinal direction of the sheet panels. The movement device moves the movable group upstream in response to the adjustment device detecting the upper threshold and moves the movable group downstream in response to the adjustment device detecting the lower threshold. If the movable group is moved, the intermittent feed device determines an intermittent feed distance based on a moving distance of the movable group in addition to output from the sensor and feeds the sheet panels by the determined distance using the first drive roller pair.

Abstract: The present invention is directed to a bag of polymeric film and a method to make the bag. The bag can be comprised of a front panel and a rear panel. The front and rear panels can each be comprised of multiple layers of film. The bag can be formed from a collapsed bubble of polymeric film that has been folded in half so that opposing edges of the collapsed bubble form an opening of the bag. One of the layers of the folded bubble can be split adjacent to an edge of the collapsed bubble and a draw tape film can be inserted between the layers of the folded and collapsed bubble. The collapsed bubble can further be embossed by a pattern that can provide enhanced properties to bags formed from the folded bubble.
