1. Working Principle of SP-FP: The black arrow indicates the direction of the fiber
mass flow as shown in figure. The 3 CCD camera that give high but uniform
illumination with two fields. The cameras detect the distorted colors or contrasts
generated by the polarization in light polypropylene and transparent or semi-
transparent PE foils. On detection of a contaminated part of the fiber mass, a
combination of a compressed air nozzle beam and speed sensor are selectively
activated to blow the contaminated part of the fiber mass fromthe fiber channel
into a waste suction unit. Therefore, the fiber mass is screened to be free of
material contaminants.
