<p>Means to sequentially transfer packaged bodies (30) carried by a conveyor (32) onto surface plates (40) rotated at equal intervals along a circular route (41) and vacuum-package the packaged bodies (30) in a vacuum chamber formed with cover materials covering the surface plates (40), wherein the feed pitch of each surface plate (40) is input into a controller (58) with pulses from an encoder (56), and a pitch between the front end sides of packaged matter (18) inside the packaged bodies is detected by an optical sensor (59) and input to the controller (58) so as to control the speed of an adjustment conveyor (35) according to a pitch displacement of the packaged matter (18) relative to the pitch between the surface plates (40). <IMAGE></p> |
