Abstract

A packaging and sealing apparatus has an opening mechanism for forming the package forcibly to an open configuration, an inserting mechanism for inserting the product into the package which has been formed by the opening mechanism, an open end forming mechanism for forming flatwise an open end of the package with the product inserted therein, a folding mechanism for folding the flatwise formed open end into a folded end, and a sealing mechanism for fixing the folded end. The opening mechanism, the inserting mechanism, the open end forming mechanism, the folding mechanism, and the sealing mechanism are successively arranged along a direction in which the package is conveyed by a conveyor.
