Abstract
Apparatus for stacking pads with spiral binders has a reciprocable and pivotable turn-around device which inverts each second pad of a file of equidistant pads before the pads reach a stacking platform. At the stacking station, the pads are arrested by an adjustable stop which locates inverted pads in a first position and the non-inverted pads in a second position so that the binders of successive pads in a growing stack are located at the opposite sides of the stack. The turn-around device is arrested in response to detection of the absence of pads in the path along which the pads move toward the stacking platform by a photocell which further transmits signals to the mechanism for moving the stop so that the absence of one or more pads does not affect the array of pads in the stack on the platform. A level detector monitors the height of the stack on the platform and transmits signals for stepwise lowering of the platform. The number of pads in successive stacks is counted and the counter transmits signals which actuate a device for removing fully grown stacks from the platform.
