Container filler and sealer with two directional flexing chain.

摘要

A filler (20) and sealer with an endless two directional flexing chain (10) having carriers thereon are capable of being driven about vertical axes of a rotary filler (20) and also about horizontal axes of end discs. Each carrier movably supports a tray supporting head (76) which is accurately maintained in filling positions relative to rotary and reciprocating tray fillers, and is thereafter accurately maintained in position to have a lid sealed on the container. Arcuate guide shoes (55) on each carrier ride in linear and arcuate tracks to guide the carriers. A push bar conveyor includes spacer rollers which engage each carrier and push the carriers around their paths of movement at uniform speed.
