This invention provides improvements in modular links and conveyor belt systems for transferring moving articles from one conveyor belt to another disposed at ninety degrees. Thus a transferring belt has specially constructed links with two integrally formed portions across the width, one for pivotable connection in a moving belt configuration and the other specially constructed with features for more effective transfer of articles from the edge of a transfer belt to a moving belt disposed at ninety degrees which excludes inter-link pivoting structure. Thus with specially formed belt edge transfer modular links, a planar edge transfer platform is formed by the upper surfaces of a series of link end and belt edge planar conveyance surfaces located on the respective belt links. The lower link edge surfaces are tapered to reside in non-contact position over the ramp of the receptacle belt formed typically by a sprocket wheel at a position where the planar conveyance surfaces on the two belts are contiguous and co-planar. The link ends are constructed for encountering the dynamic movement conditions and loading stresses encountered when the belt edge is transversed by moving articles traveling from one belt to the other. The underside surfaces at the link end are contoured typically as a circular chord feathered out at the transfer end, and having a set of ridges parallel with the pivot rods. Interdigitatable fingers extending integrally from the upper planar link end surface mate with leading and trailing links for sharing planar and vertical stresses in the cantilevered integral link end-belt edge structure.

[ We claim:] [1.] In a conveyor belt system for moving articles in transit off a source belt moving in one direction onto a receptacle belt moving in a different direction, the improvement comprising in combination, a modular link source belt disposed for conveyance of articles in a first movement direction on a belt conveying surface, a modular link receptacle belt disposed for receiving articles conveyed on the source belt to move in said different direction on the receptacle belt which presents an entrance ramp tapered upwardly toward an article conveying surface, said entrance ramp being positioned alongside a transfer edge of the source belt for receiving articles discharged from an edge of the source belt, a guard rail system disposed to engage articles conveyed on the source belt for guiding the movement direction of such articles off the edge of the source belt toward the article conveying surface of the receptacle belt, means constructing the source belt with modular belt edge links having a shaped edge ramp configuration on an under side tapered to a thin web surface at the belt edge, said tapered under side being positionable to move dynamically across the entrance ramp with minimal contact to present a small gap width for conveying articles from the source belt to the receptacle belt, and means forming an edge ramp configuration on each source belt modular link with interlocking structural means to engage adjacent link module leading and trailing edges in the source belt thereby providing distribution of weight of transferred articles in transit among a plurality of links along the source belt length for damping dynamic flexing and fluttering of modular link tips individually along the transfer edge of the source belt.
