ABSTRACT:
Apparatus is provided for erecting tubular carton blanks from a flattened to an open tubular state and includes two blank erection stations positioned sequentially along a conveyor for conveying a succession of blanks to the stations. In each station a suction head is attached to a blank and moves the blank through a cycle from a blank collection position, through a blank lifting phase, then through a blank erecting phase in which the blank is pressed against an abutment member into force the blank to an erected condition. When the suction head reaches a blank releasing position, suction head is returned. The suction heads are carried by a link arm driven in a parallel movement by cams via pivot arms.
