Abstract
A method and apparatus are disclosed for production of containers for packaging liquids. Plastic-coated supporting material is drawn as a web from a supply roll in a first direction along a web path. At a first position, the web is cut into sheets. The sheets are conveyed along a transport path in a second direction transverse to the web path. At a second position, each sheet is partially shaped into a tube, and an edge of the sheet is folded over and sealed. At a third position, shaping is completed to cause the side edges of the sheet to join, and the tube side is sealed. A plastic lid is molded onto the top of each tube, and the bottom end is folded and sealed into a quadrilangular bottom.
