Abstract

1,092,969. Testing composite filter rods. AMERICAN TOBACCO CO. Nov. 7, 1966 [Nov. 5, 1965], No. 49723/66. Heading A2C. [Also in Division G2] In a device for inspecting composite filter rods 3, and rejecting faulty rods 3, each rod 3 being composed of an axial series of alternately different components one component 5 (e.g. of cellulose) of which is more translucent than its axially adjacent components 4 (e.g. of charcoal), the rods 3 are carried on a grooved drum 6 in endwise abutment with a placement stop 9 through an inspection station as shown. Light from sources 10, diffusing through the more translucent components 5, passes through one or more apertures 13a, 13b in a tolerance mask 12 only when a defective rod 3, having its components 5 displaced from the normal position, passes through. A reflective lens 14 directs any light passing the mask 12 to a photo-cell 16 which actuates a valve 19 to reject the faulty rods 3. Precise timing of the rejection is obtained photo-electric detection of apertures 20 on the drum 6 placed diametrically opposite the rejection mechanism.
