  • Patent number: 4250693
    Abstract: Goods to be packed are continuously collected in units of goods. Parallelly therewith plain package blanks are preformed to package containers, which are completely open at least at one vertical side. The units of goods and the open package containers are moved in a continuous feeding movement side by side with the same speed, and with the open container side facing the unit of goods. During the feeding movement a unit of goods is pushed sideways into a package container. The open container side or sides are closed and sealed, and the package is moved away from the packaging station. The front side and the rear side of the preformed package container as considered in the feeding direction are widened in relation to each other before the units of goods are pushed into the containers to facilitate the pushing in of the units of goods into the package containers.
