An apparatus for the manipulation of plastic bags output from an automatic bag machine comprises an input conveyor for receiving bag elements from the bag machine, a delivery unit having two outer turnstiles spaced from one another according to the width of the bag elements, and a stacking unit. The turnstiles have suction arms to firmly hold bag elements taken from the input conveyor. The bag elements are depositable on the intermittently operated stacking unit. The stacking unit comprises an endless stacking conveyor belt provided with a plurality of pegs thereon, these pegs being spaced from one another according to the stack size. The stack-conveyor belt comprises two conveyor chains with the aforementioned pegs attached thereto, said chains being spaced from one another with a passage space therebetween. The delivery unit further comprises an additional middle turnstile and this middle turnstile is movable through the passage space between the conveyor chains. The middle turnstile performs as a double turnstile so as to be able to manipulate two plastic bags. |
