Abstract: 1,122,122. Coating machines. CONTINENTAL CAN CO. Inc. 26 Sept., 1966 [22 Oct., 1965], No. 42882/66. Heading B2L. [Also in Division B6] Tubular bodies, e.g. can bodies, are supported on mandrels 51 rotatably journalled in hubs 60 at spaced intervals along an endless conveyor 35, the conveyor being guided by sprockets to pass such that the tubular members in turn are parallel with and come into touching contact with arcuate blankets 134 (Fig. 18) of a rotatable drum 130 which is being rotated at a faster speed than the conveyor which causes the tubular member to be rotated about its axis such that its entire surface can be coated or printed by the drum. Can bodies are constantly delivered down chute 86 and received in pockets of turrets 98 and 105. A pusher unit including a cam follower pushes the can bodies from the pockets onto the mandrels 51 of the conveyor which are caused to move in alignment with the turret pockets. The conveyor then passes to the coating apparatus 32. The drum 130 is rotatably journalled on a shaft 25 (Fig. 18) extending between support plates 67 and 68<SP>1</SP>. A support assembly 157 is associated with the drum and includes a turret structure 158 with bearing sleeves 160 supported on its outer portion. In each sleeve 160 is positioned a shaft 161 provided with a cam follower 162 seated in a fixed cam track 163. When a cam body on its mandrel first starts movement about the drum a camming member (151, Fig. 19, not shown) on a sprocket 128 retains the can body in radially spaced relation with respect to the blankets 134. When the can body is disposed between adjacent blankets the associated shaft 161 moves axially and its engagement with the can body and the co-action results in radial movement of the can body and mandrel into contact with the blanket. After the coating the can bodies; still on the mandrels, are conveyed to a varnishing apparatus 33 where they come into contact with a varnishing drum of the same construction as the coating drum. After varnishing the can bodies are transferred to a chain conveyor 233 (Fig. 1) which may carry the can bodies into a drying oven.
