Abstract: A depalletizing machine for unpacking pallets, each defined by a number of stacked layers of products; each layer having a number of parallel, side by side rows of products; the machine having a work platform on which the packed pallets are positioned; a linear input conveyor for successively feeding the packed pallets onto the work platform; a linear output conveyor for conveying off the machine a succession of single products ready for use by other machines; and a separating head for successively transferring a given number of rows of products from the top of the stationary pallet on the work platform to the linear output conveyor; the given number of rows of products being less than the number of rows of products defining each layer in the pallet.
