Abstract
An arrangement on a conveyor of the type which comprises a flexible chain whereupon objects, e.g. parallelepipedic packing containers, are conveyed. The conveyor comprises guide rails (4) located on either side of the chain (1) which steer the packing container. In curves the guide rails are substituted on the one side by a curve disc (5) having a sloping steering surface (8) which acts upon the packing container outwards against the guide rails located on the opposite side of the conveyor. As a result packing containers of different sizes can be conveyed on the conveyor without the conveyor needing adjustment.

Conveyor apparatus comprising:
- means for conveying packages along a predetermined path including a curved portion, said conveying means being formed by a flexible conveying element having an upper conveyor surface;
- track means for supporting said flexible conveying element for movement along said predetermined path with a curved portion of said path;
- guide means extending along and adjacent an outer circumference of said curved portion of said path and above said upper conveyor surface for guiding packages through said curved portion of said path;
- said track means including urging means for urging packages toward said guide means while said flexible conveying element conveys the packages along said curved portion of said path, said urging means including a rotatable curve disc having a steering surface which is sloped with respect to said upper conveyor surface and which extends from a first level at least as low as said upper conveyor surface to a second level above said upper conveyor surface such that packages conveyed around said curved portion of said path are urged toward said guide means by said sloped steering surface while said flexible conveying element conveys the packages.
