A switch of a transport system for a movable transport element includes a main track and a secondary track branching off the main track. The movable transport element can be guided from a transition region in which the secondary track branches off from the main track. Devices for increasing a switching force to guide a moveable transport element along the main track or transfer the movable transport element to the secondary track are provided in the transition region.

An apparatus, system, and method for conveying an assembly along a track. A rail can include a first planar side, a second planar side, and a third planar side. The first, second, and third planar sides can be arranged to form at least two acute angles. A carriage assembly can include a drive wheel and at least two roller sets. The drive wheel can be configured to contact the first planar side and is configured to translate the carriage assembly along the rail. The at least two roller sets can be configured to contact the two other sides to maintain the carriage in contact with the rail.

A profiled bearing for a rail and a rail system are disclosed. The profiled bearing has a profiled base with a first lateral wall, a second lateral wall, and a base which connects a first end of the first lateral wall to a first end of the second lateral wall, and the profiled bearing also has a profiled clamping section. The base and the lateral walls form a receiving pocket for receiving the rail. In a functional position, the profiled clamping section is clamped in a gap between the rail inserted into a bearing bed of the base and the second lateral wall. A clamping finger which extends in the direction of the second lateral wall is molded in the region of a second end of the first lateral wall, the end being arranged at a distance from the base, wherein the rail can be pressed into the bearing bed by means of the clamping finger, and the profiled clamping section has a base web with two clamping limbs which extend from one face of the base web and which can be pressed into the gap between the rail inserted into the bearing bed and the second lateral wall. The clamping limbs of the profiled clamping section extend in the direction of the bearing bed in the functional position in which the clamping limbs are inserted into the gap, and a first clamping limb lies against the rail at least in some regions and a part of a second clamping limb is pressed into an undercut formed on the second lateral wall.
