ABSTRACT:
In a box-making machine a flat blank is passed longitudinally by a conveyor through a plurality of treatment stations at each of which a treatment element displaceable transversely to the conveyor acts on the blank to fold it up into a three-dimensional box. Each of the treatment elements is carried on a respective threaded spindle that can be rotated to position it transversely of the conveyor, and each spindle is connected via a respective electromagnetic clutch to a common drive chain. Also driven by this drive chain is a control spindle carrying a scanning device which can move past a blank or the like and generate a succession of position signals. The scanning device and the treatment elements are all jointly and synchronously displaced in one direction across the conveyor and as each of the position signals is generated the respective treatment element is arrested so that all of the treatment elements can be exactly positioned in one operation.
