with which the longitudinal edges of a packaging material web arranged above the row are guided together underneath the row see fig7 are also known it is of course also possible not to deposit the row 4 in the middle of the packaging material web 2 but on one side thereof and to fold the packaging material web around the row only from one side the fourth device 8 for making the seams comprises a means 80 for making the longitudinal seam and a means 81 for making the transverse seams as shown in the fig1 and 2 the means 80 for making the longitudinal seams is advantageously arranged upstream of the drawing means 60 and the means 81 for making the transverse seams downstream thereof any known such means which are suitable for connecting the packaging material in seams may be applied as means 80 and 81 suitably designed and arranged welding heads are in particular useful when a plastic film is used as packaging material in particular a rotating arrangement 82 of welding heads 83 which cooperate with a counter pressing belt 84 are suitable as means 81 for making the transverse seams such an arrangement is described in detail in a patent application which has the same application date as the present application per se known methods may be applied for establishing the supply stream 3 which is not part of the invention for example an imbricated stream may be deposited on a supply belt 30 using a feeder 32 which takes the objects from a stack using a winding station which takes the objects from a reel using a gripper conveyor 33 which brings the objects directly from a rotation printing machine in the latter case in.
