Abstract
A form, fill, seal and separate packaging machine wherein receptacle forming, filling and sealing is accomplished by a plurality of stations disposed along the path of travel of a web which continuously moves through the packaging machine. Both the base web material and the lid web material are supplied to the packaging machine from supply rolls of appropriate material. Not only are the work stations of the machine constructed and disposed so that the packaging operation is performed on a continuously moving web, but also both the base and lid web supplies include primary and secondary rolls so that the source of web material may be replenished without interrupting the continuous movement of the web material through the machine. Once the receptacles have been formed, filled and sealed, the packaging machine further includes an intermittent drive station for perforating and cutting the sealed receptacles from the main web body.
