摘要： A transport system for transporting material to be soldered through a soldering apparatus, and soldering apparatus with laterally movable middle support. The transport system for transporting the material to be soldered through the soldering apparatus, includes at least one transport track extending in the transport direction in which the material to be soldered is transportable in a transport plane in the transport direction, wherein the transport track includes two transport bars extending in the transport direction and at least one middle support with a middle bar extending in the transport direction. The middle bar has a revolving conveying means with folding elements, and the conveying means provides a feed in the transport direction and a return counter to the transport direction. The folding elements are displaceable between a support position and a folded position. Further provided is an adjusting device for transverse adjustment of the at least one middle support in a transverse direction running transversely to the transport direction, characterized in that a distance A between an underside of at least one transport bar facing away from the transport plane and the transport plane is smaller than a distance B between an upper side of the at least one middle support facing the transport plane and the transport plane, and that the adjustment device is designed such that the middle support with folding elements is movable in the folded position in the transverse direction underneath the at least one transport bar into a parked position provided laterally next to the transport bar.
