Method for manufacturing a material strand assembly

A method for manufacturing a material strand assembly for a vehicle, including the steps of:

• extruding strand material in an extruder so that an extruded material strand is produced,
• monitoring the quality of the extruded material strand so as to detect faults of the extruded material strand,
• in case of a detection of a fault, cutting out the fault from the material strand, using a cutting arrangement with first and second cutters, and re-joining cutting end faces, thus producing a joint, so that a faultless material strand is produced, wherein the cutting-out step is conducted by placing the fault between the first and second cutters and cutting out the fault and the re-joining step is conducted such that any two adjacent joints are at a minimum joint distance or more from each other, and
• storing the faultless material strand in a storage unit so as to produce the material strand assembly,
• wherein a feeding step includes at least one of passing the extruded material strand through a first strand accumulator between the extruder and the cutting arrangement and passing the faultless material strand through a second strand accumulator between the cutting arrangement and the storage unit.
