ABSTRACT:
An apparatus for manufacturing cross bottom sacks from laid-flat tubular sections consists of a frame having:- a table, means for holding the tubular section thereon in a processing station where the ends of the tubular section become opened out into a bottom square or rectangle, a suction gap arranged in the table in the zone of one of the ends of the tubular section, and suction means mounted in the frame above the suction gap and which is able to be raised and lowered for opening one end of the tubular section. Above the plane of the tubular section situated in the processing station, a slide can be extended and retracted over the table in the direction of the median line of the tubular section, the median line of the slide defining with the median line of the tubular section a plane perpendicular to the plane of the tubular section. The width of the slide is less than the interspacing of the hypotenuses of the two opened-out corner folds from each other. The two shaping plungers are designed in a mirror image arrangement and are mounted for being raised and lowered onto the table; their shape corresponds to the shape of the corner folds.
