Abstract

A linear measuring apparatus for measuring elongated materials such as cables is disclosed. The apparatus includes a measuring station which includes two endless belts which run over two pulleys and between which the material to be measured is drawn. The measuring station is provided with sensors to which a counter unit is connected for indication of material lengths, and the endless belts (5a, 5b) extend horizontally, side-by-side, and resiliently abut the material to be measured.
