Abstract: An improvement in an apparatus for transporting and depositing panels with smooth surfaces, comprising a conveyor having substantially horizontally oriented endless belt. A plurality of suction holders carried by said belt means with a suction cut and a venting valve which is opened for depositing said panel at a depositing position. Each of said suction cups is displaceable parallel with the transport direction in relation to the zone of attachment of its body to said belt by a stop provided at said depositing position in the transport path of said panels, which stop on arrival of one of said panels displaces all those adjacent suction cups holding said panel contrarily to said transport direction, which displacement opens the venting valves of all those adjacent individual suction holders holding said panel.
