A method and machine for fitting a sleeve seal of a collapsed form over a container, wherein the sleeve seal supplied is opened halfway by suction cups disposed to a base plate, and then are opened fully by separating the distance between opening members inserted therein, which are mounted movably up and down to the base plate, until the sleeve seal is somewhat tensioned, wherein the sleeve seal is formed in the cylindrical form just above a container to be fitted by closing the distance between the opening members while the sleeve seal is held by the suction cups, wherein the container is inserted into the sleeve seal opened by a lift supporting the container, wherein the opening members are pulled out of the sleeve seal, and wherein the container fitted in the sleeve seal is transferred to a next step.

A method for fitting a sleeve seal over a container comprising the steps of: (a) supplying a sleeve seal in a flattened form between opposing suction holding cups, and actuating the suction holding cups to hold the sleeve seal; (b) moving the suction holding cups apart so as to partly open the sleeve seal; (c) inserting opening members into the partly opened sleeve seal; (d) moving the opening members apart to stretch the sleeve seal, in such a manner that in the direction of movement of the opening members the sleeve seal is stretched substantially larger than its final dimension when fitted over the container, and in the direction orthogonal both to the direction of movement of the opening members and to the axis of the sleeve seal it is stretched to substantially less than its final dimension when fitted over the container; (e) moving the opening members together so that the sleeve seal is relaxed and adopts a shape substantially similar to its required final shape when fitted over the container; (f) inserting the container into the sleeve seal; (g) simultaneously holding the sleeve seal in position on the container and extracting the opening members; and (h) wherein substantially throughout the stretching step (d) the suction holding cups are disengaged from the sleeve seal, and the suction holding cups are reengaged with the sleeve seal during step (e) so as to retain the sleeve seal in position as the container is inserted.
