Actual factory and process configurations could vary, but our industry experts know them all.
In the spinning mill, the bale opener is the first link in a long chain of processing steps in producing yarn. The bale opener releases fibre lumps out of the bales and transfers the fibres by airflow into the cleaning section.
Main challenges
- Closure of the air channel to ensure a proper vacuum system
- Instability and vibrations hindering proper functionality
- Wear from punching and screwing
Solutions
- Laterally stable belts for closure / coverage of the air channel
- Stable and lengthwise flexible belts for smooth movements
- Rigid and wear resistance belts for longer belt life
Carding machines align lose fibres into tufts or fleece. Carding machines are driven by power transmission belts and have sliver tapes installed to guarantee a frictionless output of the carded sliver out of the machine.
Main challenges
- Limiting downtime and maintenance
- Improving the workplace ergonomics
- Fibre accumulation blocking output
Solutions
- Long service life Power Transmission Belts
- Low noise belts
- Smooth / frictionless surfaces preventing fibres sticking to the belt
The draw frame stretches and parallelizes the textile fibres, a process that balances inequalities within the slivers. The card slivers pass through several stretching units between weight-loaded rollers and are spun down in loops into spin cans.
Main challenges
- Accuracy and speed
- Fibre accumulating on the belts
- Energy consumption
- Reducing downtime
Solutions
- High quality and precision belting
- Smooth / frictionless surfaces preventing fibres sticking to the belt
- RAPPLON® Belts are durable and are extremely energy efficient
Combing is a process to prepare fibres for spinning and produces smoother, finer, stronger and more uniform yarns. Combing is commonly confined to high grade, long staple natural fibres.
Main challenges
- Avoiding fibre accumulation
- Avoiding elongation
- Waste reduction
Solutions
- Smooth / frictionless surfaces preventing fibres sticking to the belt
- Clean high grip belts provide excellent fibre transport
The spinning machines stake the roving, thin it and twist it, creating yarn. The roving is pulled off a bobbin and fed through rollers, which are feeding at several different speeds. This thins the roving at a consistent rate.
Main challenges
- Maintaining consistent spindle speed
- Producing uniform high quality yarn
Solutions
- High grip belts which can maintain a consistent tension (no elongation)
- Wear resistant precision RAPPLON® belts!
The rotor spinning process is much more efficient than Ring spinning and is mainly used for coarse yarns.
Main challenges
- Long service life by high speed
- Reducing downtime and energy consumption
Solutions
- High rubber quality provides a wear resistant surface
- Abrasion resistant belts
- RAPPLON® Belts are durable and are extremely energy efficient
Two or more single-end threads are twisted together to form one multi-ply twisted yarn. Spindles are driven by tangential belts or by separate motors.
Main challenges
- Minimising dust
- Maintaining uniform spindle speed
- Reduce maintenance costs
Solutions
- Increased shore hardness to avoid dust
- High rubber quality for precise spindle speed
- Wear resistant belts for long service life
Winders are machines for wrapping string, twine, cord, thread, yarn, rope, wire, ribbon, tape onto a bobbin. Modern machines are equipped with Elastic Belts for transporting the cop while older machines are driven by Tangential Belts.
Main challenges
- Easy fitting
- Reducing / eliminating static
- Maximising uptime
Solutions
- Wide elastic belt range
- RAPPLON® antistatic belts
- Tangential belts with XNBR rubber for long service life
For cleaning Open end, Ring-spinning, Twister, Winder and Flyer machines pneumatically. Travel cleaners dramatically minimise manual cleaning work. Flat belts move the machine forward and backward and drive also the vacuum cleaner.
Main challenges
- Extended lifetime
- Strength of the narrow belts
Solutions
- Classic Tangential Belt with polyamide tensile member
- High quality wear resistant RAPPLON®
Man-made fibres are in general very even and have less “character” when it comes to the sense of touch. Texturing is the formation of crimps, loops, coils or crinkles in filaments to give the yarn typical characteristics.
Main challenges
- High temperatures
- Heavy loads
- Abrasive environment
Solutions
- High heat compatibility
- Classic tangential belts with polyamide tensile members
- Handling heavy loads at medium speed
- Long service life – highly wear and abrasion resistant belts
