Abstract

A method and a device for spreading a fiber strand to provide a strip-type fiber strand. In particular, the initial fiber strand is provided with an initial width and thickness, and is then spread to form the strip-type fiber strand having a greater final width and a smaller final thickness as compared to the initial width and thickness. The fiber strand consists of continuous multifilament fibers.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a national phase application pursuant to 35 U.S.C. 371 of International Application No. PCT / EP2015 / 055689, filed Mar. 18, 2015, which claims priority to German Application No. 10 2014 105 464.4, filed Apr. 16, 2014. These applications are hereby incorporated by reference in their entireties.FIELD OF THE INVENTION

[0002] The invention relates to a method and a device for spreading of a fiber strand, which features an initial width and an initial thickness, to a strip-type fiber strand with greater final width and with smaller final thickness, wherein the fiber strand consists of continuous multifilament fibers.BACKGROUND OF THE INVENTION

[0003] The spreading of fiber strands has long been known and is employed on fiber strands made of polymer fibers to improve physical properties, since due to the spreading, twisting of the filaments in the fiber strand, for example, can be eliminated and a fiber strand with filaments posit...
