Interlacing Jets for BCF spinning process

BCF (Bulked Continous Filament) filament yarns are widely used for the carpet yarn production. In a BCF extrusion line the filament yarn is stretched to get the required strength, followed by an air texturing process that gives bulk to the yarn before it is fixed on a cooking drum and winded on bobbins. BCF carpet yarn manufacturers are under considerable strain to meet the high demands on quality and efficiency of the carpet and automotive industry.

BCF interlacing jets

RPE offers the whole range of BCF interlacing jets that are used for carpet yarns in BCF spinning processes to meet all requirements of interlacing performance.

The designs are changeable to satisfy customer requirements according to yarn path, machine adaptation and air supply. The jets are available in single or tandem version, with or without integrated air stop.

BCF jet inserts

RPE offers the complete range of jet inserts for any requirements on interlacing performance. The jet inserts are characterized by an easy exchange without tools for cleaning, maintenance and lot change.

All the jet inserts are available in 20mm (e.g. BXX) as well as 16mm (e.g. BSXX) yarn end separation.  Customized solutions with different yarn end separations according to special requirements are possible any time.

BCF pre-interlacing and migration jets

The SPI jets are most suitable for migration and pre-interlacing applications in BCF spinning processes.

RPE offers two types of SPI interlacing jets (A- and B-Version) with different design to guarantee optimal results regarding the specific requirements of individual assembly situations and process flows. In this context our customers are advised by experts that have long experience regarding the choice of SPI versions.

The design of the SPI jet enables also multi thread jets for all conceivable number of thread lines and yarn end separations.
