and therefore not visible fig2 shows by way of example the first side plate 5 just like the second side plate 6 or else all side plates of the paving screed 1 according to the present disclosure it is designed to be mountable at each outer end of the paving screed 1 fig3 is a schematic top view of the paving screed 1 but widened in this case by first and second bolt on extensions 13 14 in this arrangement the bolt on extensions 13 14 are exemplary of all screed configurations which may be implemented with the aid of an arbitrary number of bolt on extensions 13 14 which may be arbitrarily dimensioned as previously mentioned above the sensor units 9 10 measure the two distances a and b to the reference elements 11 and 12 in the embodiment shown the dimensions of the sensor units 9 10 must also be taken into consideration when summing up the width of the base screed 2 this can be avoided not by mounting the sensor units 9 10 as shown on the lateral surfaces of the base screed 2 but rather by attaching them flush with these same lateral surfaces for example mounting on an upper surface of the base screed 2 is conceivable it is equally feasible.
