Abstract:
1. Conveyor chain comprising a plurality of modular components having an upper conveyance plate with each modular component comprising a rotation component projecting from said plate and defining an inner seat with concave surfaces with said seat receiving therein a pivoting component engaging with said concave surfaces to rotate inside the rotation component around an axis perpendicular to the conveyance plane with said pivoting component and said 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 said rotation axis of the pivoting component with said pin being engaged with a modular component adjacent to the chain to allow 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 of a plate being designed to be drawn near the concave profile of an adjacent plate with the circle arcs described by said concave and convex profiles of the modular components having centers lying nearly on rotation axes of pivoting components of the chain, said arc profiles extending along the entire dimension of the plate transversal to the chain movement direction.
