In an automated multilayer ceramic substrate manufacturing facility, it is necessary to repeatedly pick the top ceramic green sheet from a stack of green sheets. Disclosed is a green sheet separator which ensures that a vacuum pick-up head only picks the top green sheet. The green sheet separator uses four small nitrogen jets on the periphery of the pick-up head. Referring to the Figs. 1 and 2, pick-up head 1 employs vacuum to pick the top green sheet 4 from a stack. Four separators 2 are employed on the periphery of pick-up head 1. As shown in Fig. 3, each separator 2 includes a nitrogen jet 3 which directs a 75-millisecond pulse of nitrogen to the separation point between green sheets 4 and 5 as green sheet 4 is picked up. Green sheet 5 is thus peeled away and kept in the stack.
