Abstract

A method of continuously making packages from groups of stacked items includes the steps of advancing consecutive groups of flat, edgewise standing, stacked items on a conveyor while supporting each item group by holders engaging each article group; during the advancing step, wrapping a wrapper sheet about an item group by a wrapper folding device, whereby the wrapper sheet supports and holds together the items in consecutive item groups; removing the holders from a just-wrapped article group; drawing the wrapper sheet, together with an item group wrapped in the wrapper sheet for conveying the item groups after the holders are removed therefrom; and withdrawing air from the wrapper sheet at a suction location where at least a partial wrapping has been completed, for generating a vacuum inside the wrapper sheet for causing the wrapper sheet to be pressed against edges of items in wrapped item groups downstream of the suction location.
