Abstract
An apparatus for sealing an open end of a package comprises a first longitudinally extending sealing jaw, bearing mounted on a first eccentric shaft rotatable around a first rotational axis, and a second longitudinally extending sealing jaw, bearing mounted on a second eccentric shaft rotatable around a second rotational axis, the second sealing jaw being parallel with the first sealing jaw. At least one motor drives rotation around the first and second rotational axis in opposite directions, wherein the first and the second sealing jaws oppose each other, and are allowed to oscillate between sealing and open positions by moving towards and away from each other. A first and second transversally extending guiding bar cooperate with the first and second eccentric shaft via guiding pins running in guiding grooves, such that transverse play between the first and the second eccentric shaft and the first and second sealing jaw is allowed.
