Abstract of the Disclosure The invention relates to apparatus for stacking flat articles, such as tube sections, bags of sacks, comprising two spaced apart hubs arranged to rotate in synchronism on a horizontal axis and carry- ing respective spiders, the arms of which are equally angularly spaced and on their leading sides in the sense of rotation carry suction nozzles, further comprising receiving or carrying means for the articles, which receiving or carrying means are disposed between the arms adjacent to the horizontal plane which contains the horizontal axis and protrude beyond the articles to such an extent that the side edges of the articles extent at least in part the planes in which the arms are rotat- able, further comprising a series of needles, which are disposed on that side of the axis which is opposite to the receiving means and are closely spaced from the arms of one of said spiders and extend approximately parallel to that one of said arms which is in a horizontal position and are adapted to enter perforations of the articles as the latter are delivered by said arms, and means for sucking air from said nozzles and for controlling the air thus sucked. The receiving means are preceded by a pair of pinch rollers, which are formed with spaced apart annular grooves, air blast nozzles are provided in said annular grooves on both sides of the sheeting web, which is fed by the pinch rollers, transverse severing means are provided between the pair of pinch rollers and the receiving means, and additional air blast nozzles are arranged in a row extending in the direction of conveyance and disposed laterally between the receiving means and. the planes in which thea arms are rotatable, which additional air blast nozzles include an acute angle with the direction of conveyance.
