FORFARANDE FOR INSLAGNING AV EN SOLID ARTIKEL

摘要

The invention relates to a method of forming packages for articles by feeding layers of wrapping film along aligned paths in the same direction, causing these layers of wrapping film to adhere to each other at transversely extending positions spaced apart relatively to the direction of feed, and then opening out the two layers between two successive adhering regions so that the length of film between the adhering regions forms a tube. The invention also includes a method and means whereby an opening device is introduced between the two layers of film whilst the film is in a flattened condition, and then the opennig deivce is activated to open out the tube to allow an article to be inserted therein.
