A sheet-separating device for separating individual sheets from a stack, for example in the printing machine includes pneumatically operated suction heads engageable with the uppermost sheet of the stack, a four-link transmission device effecting a vertical movement of the suction heads relative to the stack and having a swinging arm connected to the suction heads, and an oscillating device including a pivotable connecting rod connected to the suction heads, and a vertical slide connected to the connecting rod so that a limited oscillating horizontal movement is imparted to the suction heads in addition to the vertical movement.
