Spindle type straight line capper

摘要

The invention concerns an apparatus for applying closures to containers. Each closure is carried to a respective container in a chuck of a closure holder mounted on a closure conveyor. The holder has an axially movable spindle which is yieldably moved from a retracted position to an extended position as the closure conveyor moves. The spindle may be selectively rotated while in extended position, by a pulley which is coupled to it by a clutch. The closures are applied to containers moving on a straight run of a container conveyor. The closure conveyor carries the closures along a linear path parallel to the containers while the spindles are sequentially extended to apply the closures.
