I have a center line...i want to have buffer polygons 100m each right and left...but they have to be single polygons which every of them is 100m width.....so i need one 100m right, 200m right, and so on but every of them have to be 100m in width....so

Multibufferer brings me the right target but the transformer gives me donut geometry with a polygon right one left and a line which connect both of them...so whats the process when i want this....

 

or is another transformer better?

The MultiBufferer has a parameter "Create Donuts", it defaults to 1 which means it will create donuts. Set it to 0 to not have it do that.

Hope this helps.

Can you share your MultiBufferer settings? I can't seem to reproduce this behaviour. Is this the output from the MultiBufferer or did you add other transformers?

Okay, try this:

 

The key is that you do make donuts but then through intersecting those with the original line and building areas from the result you get your individual left/right areas.
