ABSTRACT A method and apparatus for determining the length of a flexible web or string material The length of a flexible web or string material, such as a textile material, forming a wound body or roll may be determined by determining a first measure of the weight of the web or string material, determining a second measure of the weight of a predetermined length (I) of the material, and calculating the total length of the flexible web or string material on the basis of said predetermined length (I) and said first and second weight measures thus, a roll of a textile material may be placed on a table divided into sections, of which a first section supports the roll while a second section support the predetermined length (I) of the material. The second section and the web material arranged thereon may be supported by a weighing cell and the whole table and the web material or textile material arranged thereon may be sup- ported by another weighing cell. Weighing signals from the weighing cells may be supplied to a calculating device for calculating the total length of the web material.
