  "abstract": "The invention relates to a profile system of closed and open extruded aluminum profiles for quick and easy construction of single and multi-store conveyor structures and eliminates the need for expensive fasteners. The system includes open aluminum profile "leg" (1), closed rectangular profile "crossbar" (2), a basic closed conveyor profile (3) and a sequence of motorized rollers (4) and passive rollers (5) mounted to the conveyor profile (3). The system provides stability, ease and flexibility during installation and adaptation in different operating conditions.",
