- the lower part drive 49 is designed with exactly one drive source.
- a coupling of the respective sewing lower part 10, 11, which is not shown in detail in the drawing, is used to separate one of the lower parts 10, 11 of the sewing material from a drive train of the lower part drive 49 designed as a chain or belt.
- the lower part drive 49 can also be designed with two independent drive sources for one of the two sewing lower parts 10, 11.
- the sewing lower parts 10, 11 can be moved independently of one another into a parking position, in which the respective hook thread storage container can be exchanged for a hook thread changing storage container, i.e. in particular a bobbin change, via the access windows 14, 15. is possible.
- This exchange can be automated, i.e. without manual intervention. Alternatively, a manual or semi-automatic exchange can also take place.

- a spatial synchronization accuracy along a drive displacement direction of the drives 48, 49, i.e. along the x-axis, is better than 0.3 mm. This synchronization accuracy can be in the range of 0.1 mm.
- the needle and gripper must be synchronized because the separate drives must be coupled.
- the lower sewing part 10 which is not currently sewing, is in the left parking position.
- a hook thread storage container exchange can take place in the position according to FIG. 11 on the lower sewing part 10 during the sewing operation of the upper sewing part 8 with the other sewing lower part 11.
- the sewing lower part 10 is ready for operation again.
- a temporary termination of sewing takes place, controlled via the control unit, and the previously sewing sewing lower part 11 is moved into the right parking position according to FIG. 12 with the lower part -Drive 49 relocated.
- the interaction of the upper part drive 48 with the lower part drive 49 synchronizes the sewing upper part 8 with the now freshly filled sewing lower part 10.

- Fig. 27 shows the following situation in which, after the sewing material holder 172 has been completely accommodated in the sewing material holder receiving position, the entire level lifting table 20 is displaced in the positive z-direction by means of the plate lifting drive 57, so that the upper table top level 60 is aligned with the worktop level 62 is aligned.
- Fig. 28 shows the subsequent instantaneous position in which the roller conveyor pairs 54, 55 are further displaced in the positive z direction by means of the roller conveyor lifting drive 56 relative to the table tops 27, 28 compared to the position according to FIG. 27.
- the lower roller level 59 lies slightly above the upper table top level 60, so that the sewing material holder 17i now rests on the roller conveyors of the lower roller conveyor pair 55 in the upper sewing material holder position.
- Fig. 29 shows the subsequent instantaneous position in which, after gripping the sewing material holder 17i with the sewing material holder gripping device 21, the sewing material holder 17i passes through the portal 5 onto the worktop 18 of the work table 19 is drawn.
- This equipped material holder 17i can be sewn now or at a later time, as will be explained below, as was explained above in connection with the material holder 172 in the current position according to FIG. 20.
- the other sewing material holder 172 is still in the sewing material holder receiving position on the roller conveyors of the roller conveyor pair 54.
- FIG. 30 shows the subsequent instantaneous position, in which the entire floor lifting table 20 with the plate lifting drive 57 is further displaced in the positive z direction. In this position, the lower table top level 61 is aligned with the worktop level 62.
- This shift into the current position according to FIG. 30 takes place after the material holder 17i comes to rest completely on the work table 19 and no longer overlaps with the level lifting table 20 in the y direction.
- Fig. 31 shows the subsequent instantaneous position in which the two pairs of roller conveyors 54, 55 were lowered back into the raised plate position, in which the z-distance d exists between the two roller levels 58, 59 on the one hand and the two table top levels 60, 61 .
- the lower table top level 61 continues to be aligned with the worktop level 62.
- Fig. 32 shows the subsequent instantaneous position during which the finished sewn material 34 can be removed from the material holder 172.
- 35 shows the current position in which, on the one hand, the material holder 17i can be sewn, as long as this has not taken place in the current position according to FIG. 29, in accordance with what was described above with reference to 20 was explained and in which, on the other hand, the material holder 172 is loaded, as was explained above with reference to FIGS. 3 ff.
- the lower table top level 61 continues to be aligned with the worktop level 62.
- Fig. 33 shows the current position in which the still unequipped sewing material holder 172 is completely pushed back onto the roller conveyors of the upper pair of roller conveyors 54 and comes to rest above the upper table top 27 at a distance d.
- Fig. 34 shows the subsequent instantaneous position in which the two pairs of roller conveyors 54, 55 are shifted in the negative z-direction into the lowered plate position, with the material holder 172 being placed on the upper table top 27.
- Fig. 36 shows the following current position, in which the finished sewn material holder 17i is placed on the lower table top 28 with the help of the sewing material gripping device 21.
- Fig. 37 shows the subsequent instantaneous position in which the sewing material holder 17i is pulled from the lower table top 28 back onto the work table 19 for sewing with the aid of the sewing material holder gripping device 21.
- the current position according to FIG. 39 corresponds to that according to FIG. 21, with only the material holders 17i and 172 being swapped, otherwise but the same sewing and assembly situation as well as the same positioning of the material holders 17i, 172 in relation to the sewing system 1 is present.
- the cycle of FIGS. 21 to 39 can now be repeated continuously.
- this gripper supply is exchanged, as explained above in particular in connection with FIGS. 10 to 12, whereby the sewing process when changing the sewing lower parts is compared to the exchange time of the gripper supply 10, 11 is only interrupted for a significantly shorter period of time, which lasts, for example, only 25%, 20%, 10% or an even smaller proportion of the exchange period.
