Abstract:
A seamer apparatus adapted to receive a container body and an end closure therefor at an upstream end and operative to seam a peripheral edge of said end closure onto a first end edge of said container body to form a seamed container as said end closure and said container body move from the upstream end to a downstream end comprising:(a) a movable container support including a freely rotatable turntable operative to rotatably support said container body;(b) a movable end closure support including a freely rotatable chuck operative to engage and support said end closure on the first end edge of said container body, said end closure and said container body defining an unseamed set;(c) a transport including a pair of loop conveyors each having an advance section, a downstream reverse section, a return section and an upstream reverse section, said advance sections being in opposed facing relation, a first conveyor being operative to transport said container support in a transport direction that is linear along the advance section thereof from the upstream end toward the downstream end and a second conveyor being operative to transport said end closure support in the transport direction;(d) a seaming element having a seaming groove formed thereon and operative in cooperation with said chuck to engage the peripheral edge of said end closure and the first end edge of said container body and rotate said unseamed set as it is transported therealong, said seaming groove and said chuck configured to seam the first end edge and the peripheral edge together to form said seamed container as said unseamed set is advanced linearly along said seaming element; and(e) a conveyor drive operative to drive said first and second conveyors.
