  • Patent number: 5272985
    Abstract: In apparatuses of the generic type, single point modules are provided which can transfer only the transport wagons arriving from one point branch optionally into one of the two other point branches. It is achieved by the development of the point modules according to the invention as T-shaped double point modules (40) that each point branch (42, 44, 46) can be connected optionally to one of the other two point branches, which results in a construction of a network transport path system of a simpler construction which requires less space and provides a better overview. For narrowing the spacing of parallel transport path routes (76, 80), point modules (72) are proposed whose branch angle is less than 90.degree., preferably 45.degree.. Apparatus with flexible transport path and assembly systems in industrial production plants are a preferred application sector.
