Abstract: An apparatus for sealing tops onto openings of packs arranged at a distance (m) from each other. The apparatus includes a first conveying means, e.g. a first conveyor, for intermittently conveying the packs in a first direction of travel through a row of at least three sealing stations spaced a machine pitch (m) from each other, and a transport apparatus, e.g. a second conveyor, for transporting the tops in a row behind each other and transversely to the first direction of travel, intermittently over the openings of packs located in the row of sealing stations. The transport apparatus includes a tops belt guided over drive rollers to which the tops are detachably attached behind each other using holding bridges. The tops are spaced a belt pitch (t) from each other and the tops belt is provided with positioning apparatus for properly positioning the tops over the openings.

Abstract: In order to twist single packs transported in a row through 90.degree., for example, in such a way that after all the packs have passed through the device, the row which is still disposed in the conveyer device is turned, it is proposed that a workpiece carrier (1) be arranged detachably on the conveyer line and be able to be brought to engage with a decoupling unit (E,E') which has a rotating member (5,5') driven pivotally with a first axis (6,6'), and that the first axis (6,6') is oriented vertically to the direction (3) of transportation of the conveyer device.
