Transport system for transporting soldering material through a soldering apparatus, and a soldering apparatus

Soldering apparatus through which soldering material can be transported along a transport direction, comprising a transport system for transporting the soldering material through the soldering apparatus and having two transport tracks running parallel to one another and extending in a transport direction, wherein each of the transport tracks comprises two transport rails, and wherein at least one of the two transport rails of the respective transport track is adjustable in the transverse direction running transversely to the transport direction for a width adjustment of the respective transport track, characterized in that a plurality of guide elements are provided at least on the adjustable transport rails, wherein the guide elements interact with transverse rods extending in the transverse direction, wherein guide elements adjacent in the transverse direction of transport rails adjustable in the transverse direction are each guided displaceably on the same transverse rod toward one another and away from one another, and wherein the guide elements each have at least one recess and/or at least one projection extending in the transverse direction in such a way that a projection of the respective one guide element engages in a recess of the respective other guide element when adjacent guide rails are displaced toward one another.
