    摘要: A suction belt conveyor for a sheet processing machine includes an operationally revolving endless suction belt having, at an outer side thereof a filigree structure formed by indentations, the suction belt being formed with penetrating bores terminating in the indentations. In a variation of the foregoing, the suction belt conveyor for a sheet processing machine includes an operationally revolving endless suction belt formed with pores distributed in longitudinal and transverse directions of the suction belt, so that the suction belt is air permeable.

    摘要: Individual sheets are singled out in a delivery of a sheet-fed rotary printing press. The delivery has a chain delivery with gripper bars extending transversely to the sheet-transport direction. The gripper bars are disposed on revolvingly driven transport chains and carry spaced apart sheet grippers disposed side by side. The sheet grippers grip the leading edges of the sheets and slave them to a main sheet pile. The gripper release is subject to an adjustable control for delayed sheet release, so that selected sheets may be transported beyond the main sheet pile. Revolvingly drivable suction tapes suction-grip the sheets which are released by the grippers with the delay, and they transport those sheets in the transport direction across and beyond the main sheet pile and onto a single sheet depository. The sheet depository is movably disposed in or on the printing-press frame. The suction tapes have upper suction surfaces at a raised position which extend between the sheet grippers. The grippers delay the sheet release until at least a leading region of the respective sheet is located above the suction tapes.
