ABSTRACT:
A machine for fitting a sleeve seal of a flat form over a container, wherein a pair of half-mandrels are mounted on a rotating member so as to be movable apart and together. A pair of suction cups grip the sleeve seal and move apart so as to somewhat open it; then the suction cups move, together, towards the axis of the rotating member so as to put the sleeve seal over the half-mandrels, which are together; then the rotating member rotates and the half-mandrels move apart to open up the sleeve seal; and then the half-mandrels are aligned over the container, and a pushing means pushes off the sleeve seal from the half-mandrels.
