the contact surface on the sewing machine is further expanded cf fig4 a to 4 c in front of and behind the free arm 31 viewed in the direction of sewing in this arrangement it is obvious that the processing of tubular work pieces is not possible for this purpose as shown in fig3 a to 3 c the slide on extension table 35 must be removed so that the slide on extension table 35 forms a plane with the surface of the free arm 31 when the embroidery module is docked the surface of the embroidery module 1 lies at the height h 2 i e offset by the thickness d of the slide on extension table 35 deeper than the surface of the free arm 31 which lies at the height h 1 h 1 u2212 h 2 d this difference in height between the surface of the free arm 31 and that of the embroidery module 1 does not interfere with sewing or embroidering without the slide on extension table 35 in contrast these steps optimize the accessibility of the free space 33 between the embroidery module 1 and the free space 31 in fig5 a 5 c and to 6 a 6 c the embroidery hoop support 13 is placed on.
