DISPOSITIVO PER IL CONTROLLO IN CONTINUO DEL CONTENUTO DI UN INVOLUCRO TUBOLARE

A tubular casing (1) to be checked moves longitudinally in a continuous manner through a passage (24) in a head (16). At one side, this passage (24) comprises a light-emitting source (41) and on the other side, a photoelectric pick-up member (42). The passage (24) has a U-shaped section with paralle...

Zusammenfassung:A tubular casing (1) to be checked moves longitudinally in a continuous manner through a passage (24) in a head (16). At one side, this passage (24) comprises a light-emitting source (41) and on the other side, a photoelectric pick-up member (42). The passage (24) has a U-shaped section with parallel walls and the base of which has a surface in the form of a projecting dihedron (25), the edge of which is situated at least approximately in the bissecting plane of the U, at a distance from the trajectory of light ray equal to at least one and a half times the width of the passage (24). The head (16) may be raised by pivoting.
