摘要： Transforming machines for changing a strip of unopened bag precursors into open bag precursors are disclosed that include a drive motor, a separation station, a sensor electrically connected to a controller that is electrically connected to components of the separation station. The separation station includes a first roller, a separation roller driven by the drive motor, and a pressure device having an actuator selectively activating the pressure device to apply pressure to the strip of unopened bag precursors passing over the first roller. In operation, the controller, based on a signal from the sensor, determines when perforations are located in a gap between the pressure device and the separation roller and at that time signals the actuator to activate the pressure device, with the drive motor driving the separation roller, thereby separating the perforations in a first film layer, but not the perforations in a second film layer.

摘要： A bag mouth opening device for continuously conveyed bags including suction cups (16, 17) continuously rotated in mutually opposite directions along substantially symmetrical elliptical moving paths (24, 25) on ether side of a conveying path (1) for bags. The time the suction cups take to make their single rotation along the moving paths matches the time a bag (20) takes to be conveyed for an inter-bag distance(s). The major axes (26, 27) of both moving paths of the suction cups are inclined at almost the same angles relative to the conveying path and digress from the bag conveying path toward their anterior side.

摘要： THE SUPERIMPOSED LAYERS OF THE ENDS OF FLATTENED FLEXBLE TUBES USED IN BAG MAKING ARE FIRST SEPRATED GRADALLY BY SUCTION MEANS OPERATING ON THE OPPOSITE SIDES OF THE FOLDED TUBES ADJACENT THE ENDS THEREOF AND ARE THEREAFTER OPENED RAPIDLY. THE SUCTION MEANS COMPRISE OTHER SUCTION TABLES WHICH CAN BE MOVED APART DURING STATIONARY PERIODS IN STEP-CONVEYANCE OF THE TUBES, OR WHERE THE TUBES ARE CONVEYED CONTINUOUSLY, COUNTER-ROTATING SUCTION ROLLERS OR BELTS. AFTER INITIAL SEPARATION OF THE LAYERS THE TUBES ARE PASSED TO A SUBSEQUENT STATION WHERE THE ENDS ARE RAPIDLY OPENED COMPLETELY.

摘要： In a device that opens the mouth of each one of the bags that are suspended with the mouths facing upward and conveyed in a vertical state at a uniform speed and uniform spacing in a straight line, a pair of suction disks revolve continuously in mutually opposite directions on circular tracks on the horizontal plane so that the suction-chucking surfaces of the suction disks are always caused to face each other. The suction disks revolve at a constant speed while maintaining substantially symmetrical positions relative to each other and revolve at the same speed as the speed the bags are conveyed.

摘要： 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.
