ABSTRACT:
This article attaching apparatus (10) for attaching a coin or similar object (38) to each of a sequence of continuously moving carrying sheets (14) includes a vacuum belt conveyor (24) for transporting the carrying sheets through a gumming station (26), where said sheets are provided with an adhesive area (34), to a location below a coin storage assembly (81). The coin storage assembly includes a feed tube (142) from which an individual coin is deposited onto the carrying sheet adhesive patch without interruption of the forward movement of the carrying sheet (14) by a feed wheel assembly (80) the feed assembly being mounted to a support frame (60) and disposed between the coin storage assembly and the carrying sheet. The feed wheel assembly includes a rotatable feed wheel (102) having opposed inserts (122, 124) each provided with a circumferentially disposed coin-receiving groove (134). The feed wheel is sequentially supplied with vacuum pressure and positive pressure from an air supply unit (114), which includes a stationary air valve (150 ), so that the coin is picked up under vacuum pressure from the coin tube and held during rotation to the deposit point where it is momentarily subjected to positive pressure to facilitate deposit. A spring-loaded anti-jamming device 220 is provided adjacent a cut-away portion (232) at the lower end of the coin tube.
