I have a shape file containing for each 100m a line segment representing a 100m segment of a railway line. I would like to create for each line segment a buffer polygon that has no overlap with neighbouring buffers in railway lines to corner.

Creating an indivdual buffer for each 100m line segment results into the following buffers:

As you can see the buffers are having gaps wen the line is cornering.

In order to avoid the gaps I created a single line using the LineCombiner and then using the Bufferer to create a single polygon. Next step would be to 'cut' this single polygon into polygons with a length equal to the original 100m line segment.

Following the result of the LineCombiner and the Bufferer:

Does anybody have an idea on how to cut this long polygon into 100m polygons?
