ABSTRACT:
Method and apparatus for continuously forming covers; particularly covers that are attached to flexible commodity-containing packages. The preferred method of this invention includes the steps of continuously directing at least two webs into overlying relationship with each other; feeding the flexible commodity-containing packages between the overlying webs; pressing overlying webs into engagement with the flexible packages for attaching the webs to the packages to form a composite and severing the composite at spaced-apart intervals to form a plurality of discrete articles which have a cover including sections of the overlying webs. An apparatus for continuously forming the covers also forms a part of this invention.
