Abstract
An apparatus for a flying change-over of a synthetic plastics strip (13, 13') from a first drum with a roll (3, 3') of this strip to a second drum carrying a roll (3, 3') of the same synthetic plastics strip (13, 13') has, in addition to the two drums, a cutting (9, 9') and gluing (5) means as well as control means (6) for actuating the various drives. To reduce the number of packages which are wasted in the package production machine, even though the production machine continues to operate even while the drums are being changed, it is according to the invention envisaged that direction-changing (15, 16, 18, 21), guide (8, 8') and pressure-applying rollers (7, 7') should be adjustably disposed and symmetrical in relation to a central line m which extends at right-angles to the connecting line v between the axes (4, 4') of the two rolls (3, 3'), and in that in each case one pressure-applying roller (7, 7') is adjustable in relation to the other and in that the adjusting drive (31, 31') for this can be controlled by a switch (10, 10') which is actuated as a function of the position of a roll sensing roller (26, 26').
