helix type path shifting of the offset of the forming channel relative to the textile fabric occurs continuously as can be seen from the illustration in fig6 b forming channel 20 is limited on the one side 34 by two lateral limiting areas 29 32 of both forming belts 23 24 whereas on the other side 35 forming channel 20 is limited laterally by coating segment 4 a which was produced immediately prior here the two forming belts 23 24 overlap the initially formed coated segment 4 a so that on the one hand they rest on this coated segment 4 a and on the other hand provide forming channel 20 as already explained the initially formed coated segment 4 a has a tab 12 a in the overlap area 11 a protruding in cross machine direction cmd and the additional subsequently formed coated segment 4 b has a corresponding recess 13 b with which tab 12 a engages subsequently in the method a bond between the two coated segments 4 a and 4 b is caused in overlap area 11 a as already explained in the description of fig4 and 5 the two adjacent partially wide coated segments 4 a and 4 b are formed in that the continuous textile fabric 5 is coated with polymer material 22 in a partial width path 19 which runs around textile fabric 5 in a continuous helix type pattern immediately after application of polymer material 22 a conversion from the viscous state to a solid state of polymer material 22 is caused here it is conceivable that the bond of the two coated segments 4 a and 4 b in overlap area 11 a and.
