Abstract

A method for producing a braided preform, includes the steps of: a) creating a braided sleeve from filler threads and braiding threads in a braiding process, for which purpose the filler threads and braiding threads are taken off thread accumulators, b) feeding a core to the braided sleeve, c) continuing the braiding process, wherein the core is advanced such that it is braided along its length, wherein, during step c), the take-off of at least one filler thread is blocked such that the at least one filler thread is pulled out of at least one section of the braided sleeve surrounding the core.
