Abstract
A cardboard sheet-feeding device used for feeding corrugated cardboard one sheet after another, such as to an automatic box-making machine. The cardboard-feeding device has a frictional conveyor belt driven in one direction, a control plate located above the frictional conveyor belt, and a positioning device for stacking sheets of cardboard upon the frictional conveyor belt behind the control plate, whereby upon movement of the frictional conveyor belt the bottom most cardboard sheet in the stack stacked on the friction conveyor belt is fed forward, slipping under the control plate. There is also provided a cardboard-holding device which is supported and driven by a pair of endless movable loops, the loops being driven via a sliding clutch, and which exerts pressure on the stack of sheets to correct warping of the sheets regardless of the height of the stack.
