ABSTRACT:
In apparatus for forming and taking away packets of bags deposited on a collecting table by a rotary depositing cylinder of a bag-making machine, the table extends substantially radially to the depositing cylinder, the packets of bags are successively withdrawn by gripper units which pass through the collecting table and take them away in a direction opposite to the direction of rotation of the depositing cylinder. Long and short holding fingers engage through recesses in the collecting table from beneath the latter and project beyond same, are movable longitudinally of the collecting table, can be flexed towards the depositing cylinder and have ends projecting away from the depositing cylinder periphery. The short holding fingers are mounted for reciprocating sliding motion substantially tangentially to the depositing cylinder between their retaining position and a lowered position below the plane of the collecting table. A control is provided which moves the short fingers to their holding position after the packet of bags has been taken away and descends again after the first few bags of the next packet have been collected.
