Abstract
A method is described for the production of a multiple width fiber strip consisting of crimped interlaced filaments and having several zones extending in longitudinal direction of the fiber strip as well as at least one predetermined tear line (4) extending in longitudinal direction of the fiber strip, wherein the tear strength (daN) of the fiber strip, referred to the total denier (dtex) is at least about 1.7.times.10.sup.-4 daN/dtex. The method produces one or several such fiber strips, with several separate bands (1, 2) being formed of substantially parallelly extending filaments and the formed bands being crimped jointly to produce one or several crimped fiber strips. The method makes possible the production of a multiple width fiber strip with the predetermined tear line referred to, processing on a double skein filter rod machine with a single (individual) treatment section.
