Abstract
A button attaching machine has a chute assembly for conveying button parts and a blocking device for preventing button parts from falling from a detachable intermediate chute of the chute assembly when the intermediate chute is detached. The blocking device comprises a spring-loaded plunger supported by the intermediate chute adjacent to a lower end thereof and reciprocably movable in a plane perpendicular to the longitudinal axis of the intermediate chute. The plunger is normally held in engagement with a lower chute to retract away from a button-parts guide channel of the chute assembly, and upon detachment of the intermediate chute, it is movable into a blocking position where it is disposed below the channel and spaced from the lower end of the intermediate chute by a distance which is small enough to block the passage of the button parts.
