Abstract
A gripping device for transporting a stack of flexible sheets includes two substantially horizontally spaced, parallel tines arranged for supporting the stack; and a counterelement supported above the tines in alignment with the spacing therebetween. The counterelement has a horizontal dimension in a direction parallel to the spacing between the two tines. A horizontal dimension is smaller than the spacing between the two tines. A device moves the counterelement substantially vertically towards or away from the tines. When an unstabilized stack of flexible sheets is received on the two tines and the counterelement is moved towards the two tines for gripping and stabilizing the stack therebetween, the counterelement and the two tines produce a curvilinear bending in the stack about a horizontal axis oriented parallel to the two tines when the counterelement is moved past an initial plane containing a top layer of the unstabilized stack.
