    摘要： In a method and apparatus of making the bottom of a flat tubular section, a tubular section is transported by a conveyor at a continuous rate in an alignment transversely to a longitudinal direction of the conveyor, with a first suction unit partially opening one end of the tubular section. Subsequently, a spreader unit is inserted into the partially open end of the tubular section and moved in a first phase in a substantially linear horizontal motion toward an end position in which the spreading unit conforms to fold lines of a finished bag bottom. In a second phase, the spreader unit swings from a substantially horizontal alignment into a substantially vertical position about a horizontal pivot axis by way of a compound motion in which a movement of the spreading unit into the end position is superimposed by a movement into the vertical position, thereby forming the open bag bottom. Thereafter, the spreader unit is withdrawn from the bag bottom while maintaining the formed bag bottom in vertical disposition by means of a second suction unit for further processing.

    摘要： This invention relates to a structure for guiding tubular blanks through a sack end forming station through which the tubular blanks are transversely conveyed on a path of travel, said structure comprising two plates, which are disposed on opposite sides of said path of travel, and guiding surfaces associated with said plates and defining adjacent to said path of travel a gap which has a width that is at least as large as the thickness of the tubular blank. At least one of said guiding surfaces is formed by a bar, which is associated with one of said plates and capable of a limited movement in the plane of said plate and is urged toward the other plate by springs.

    摘要： An apparatus for spreading open flattened bags has a first air-pervious endless belt having a working flight provided with a working face and an opposite, reverse face; and a second air-pervious endless belt having a working flight provided with a working face and an opposite, reverse face. The working flights of the first and second belts are divergent at an acute angle in the bag conveying direction. There is further provided a suction device generating a vacuum for urging a gas to flow across the working flights in a direction from the working face to the reverse face of each working flight, whereby each bag introduced between the working flights adheres, with opposite bag panels, to the working faces of the working flights and is forwarded thereby in the conveying direction, while being gradually spread open.
