ABSTRACT:
An apparatus to cap in succession containers transported in serial order on a conveyor belt. The apparatus comprises a cap dispensing station operating in a timed-relationship with the container feed rate to loosely apply on each container a screw-type cap in thread alignment with the threads on the container neck. The cap dispensing station includes a cap relase passage at least partially closed by a resilient lip preventing a cap to travel through the passage under the effect of gravity. A selectively actuatable cap ejector drives the cap out of the passage against the resiliency of the lip, freeing the cap which is deposited on a container underneath. During the cap movement through the passage, the resilient lip frictionally engages the cap, guiding same, to allow precise positioning of the cap on the container. A cap tightening station is provided downstream of the cap dispensing station to rotatably engage the caps loosely applied to the containers to tighten same.
