  • Patent number: 5168978
    Abstract: A conveyor system having transverse positions for use in conjunction with diverting or sorting and detecting operations. The conveyor system employs elastic strand members which are driven by a drive roller connected to a supporting frame in a transversely fixed manner while the strands are moved transversely by a guide roller positioned at an opposite end of the supporting frame. The conveyor system is especially adaptable to dynamic weighing and counting systems. The conveyor system affords a rapid adjustment for different transverse positions employing a positioning mechanism which is activated by two fluid and preferably pneumatically driven cylinders with activating rods.
