PURPOSE:To reduce the frictional force between the lowermost sheet of paper and a support plate by providing a convex or concave groove directed to the direction of delivering said sheet on the rear portion of the upper surface of a lowermost sheet supporting plate to introduce deeply between said sheet and support plate gas jetted from a blasting means. CONSTITUTION:Air injected from an air blasting unit 5 is supplied between laminated blanks 7 and between the lowermost blank and a tray bottom plate 1. As a convex groove 3 is then provided in the rear portion of the tray bottom plate 1, a gap between the lowermost blank 8 and the tray bottom plate 1 is widened toward the rear portion of the tray bottom portion 1. As a result, although the laminated blanks 7 are mounted long along the direction of feeding out, air supplied between the lowermost blank 8 and the tray bottom plate 1 flows rearward to separate the lowermost blank 8 completely upward from the tray bottom plate 1 and thus reduce the frictional force acting between both 8 and 1. |
