Apparatus for forming packaging units

An apparatus for producing bundles of containers received from a wide container stream that is converted into plural single-track container streams, said apparatus comprising a dividing-off and/or compactor unit, application elements, a linear transporter, a transport element, a controllable drive, a guide element, and head guides wherein said dividing-off and/or compactor unit divides off and compacts a predetermined number of containers to form a partial bundle to be combined with other partial bundles to form a full bundle, wherein said application elements are configured such that at least one contact face of at least one container in a bundle of containers has an adhesive and/or an application of adhesive thereon, wherein said transport element is a constituent of said linear transporter, wherein said controllable drive is a constituent of said transport element, wherein said transport element is movable back and forth linearly along said guide element, wherein said head guides are constituents of said transporter element, wherein a cardinality of said head guides equals a cardinality of containers in a bundle of containers, wherein said head guides are at least one of axially movable relative to said transport element and rotatable relative to said transport element.
