ABSTRACT:
Conveyor chain including a plurality of modular components having an upper conveyance plate with each modular component having a rotation component projecting from the plate and defining a seat with concave surfaces with the seat being designed to receive a pivoting component suited to engage with the concave surfaces to rotate inside the rotation component around an axis perpendicular to the conveyance plane with the pivoting component and the rotation component presenting holes for receiving a pin parallel to the conveyance plane and nearly transversal to the chain running direction with the holes in the rotation component being elongated to allow rotation of the pin around the rotation axis of the pivoting component and with the pin being engaged with an adjacent modular component of the chain to allow its rotation outside the conveyance plane and with the conveyance plate presenting on one side a concave circle arc profile and on the opposite side a convex circle arc profile with the convex profile being designed to be drawn near the concave profile of an adjacent plate with the circle arcs described by the concave and convex profiles of the modular components having centers lying nearly on rotation axes of pivoting components of the chain.
