The linear feeder type SLA ensures a defined and precise interface to bowl and linear feeders or separations. Through a stiff fixation of the linear feeder the SLA shows a steady running behaviour independently from the connected mass of the substructure and therefore, takes no influences from the environment. Lateral oscillation is avoided, resulting in a stable transition with safe feeding, particularly with critical part geometries. The bolt-fixing is completely free of resilient elements and adjusted Drilling holes simplify the adjustment of the liner track junction for an accurate positioning. The spring angle can centralised adjusted without changing the magnet gap.
