Abstract
Abstract A method and apparatus for supporting flexible open-ended container bodies, such as formed of plastic, in a closing machine are provided in which the body is moved laterally into an openended partial supporting mold, an end closure member is positioned in aligned relation with the open end of the body, a second partial supporting mold is moved against the side wall of the body at the open end of the open-ended partial mold, and both of the partial molds with the body therebetween are moved into a seaming mechanism whereby the side walls and open end of the body are supported by the partial molds during attachment of the end closure to the body.
