Claim:
1. A method of determining the longitudinal elongation of a knitted netting with respect to a target elongation, comprising: providing the knitted netting including first longitudinal franzes, first lateral schusses, at least two second longitudinal franzes, and at least one second lateral schuss, the schusses knitted with the franzes to form the knitted netting, wherein first longitudinal franzes and first lateral schusses are configured such that the spacing of the first longitudinal franzes decreases by less than 10% when elongating the knitted netting by 50% of the target elongation, the target elongation being from 15% to 400% of the length of the knitted netting, and wherein the second lateral schuss is an indicator schuss, the second longitudinal franzes are indicator franzes, and the indicator schuss is knitted with the indicator franzes to form an elongation indicator for indicating the amount of longitudinal stretching of the knitted netting, the elongation indicator being configured such that the spacing of the indicator franzes decreases by more than 10% when elongating the knitted netting by 50% of the target elongation; stretching the netting in longitudinal direction; and determining the longitudinal elongation of the knitted netting from the elongation indicator.
