FIELD: materials handling facilities. SUBSTANCE: method of unpiling the stack or separating sheets in stack from another includes operations at which two separating devices are brought into contact with opposite edges of stack and owing to the fact, sheet is exposed to action of force whose first component is directed at right angles to the stack. Second component is directed in plane of sheet and from separating device to stack. Auger or screw is used as separating device. proposed device has at least one separating device with number of catches which, if viewed from side of stack, are displaced in direction of feeding coming into engagement with stack to separate sheets from stack, one be one. Separating devices at upper opposite edges of stack are arranged for engagement with stack. Directions of device feeding are inclined inwards and upwards to point above stack. EFFECT: possibility of unpiling sheets differing in thickness and dimensions with accurate positioning for subsequent machining. 20 cl, 8 dwg
