Rubber Roller Surface Inspection, Polishing and Cycle Replacement for Texturing Equipment

Timely surface treatment and periodic replacement of rubber rollers can lower roller slip induced tension fluctuation below 1.5% in filament workshops. Data comes from spindle tension records and end break statistics, showing roller surface state determines yarn conveying stability. Maintenance teams often search textile rubber roller refurbishment supplier, false twisting rubber roller polishing specification, roller surface aging fault symptoms, filament slippage troubleshooting, false twisting machine and chenille machine differences, high-speed filament traction scenarios, rubber roller installation and pressure adjustment, textile rubber roller reliable vendor, nitrile rubber and polyurethane rubber roller comparison, traction roller maintenance optimization solution ranking to manage traction rollers.

Rubber traction rollers provide friction force to pull filament and control drawing speed. Long-time operation will form fiber embedded marks, surface glaze and wear grooves on roller surface. Glazed surface reduces friction coefficient, causing yarn slip. Slip leads to unstable drafting ratio and inconsistent physical indexes of yarn.

Daily visual inspection observes surface gloss, crack, hardening and local indentation. Minor glazing can be removed by professional polishing. Polishing operation controls grinding depth evenly, avoid excessive grinding which shortens roller service life. Seriously cracked, hardened and grooved rollers must be replaced directly instead of repeated polishing.

Roller pressure adjustment is matched with yarn specification. Too small pressure causes slipping; excessive pressure accelerates rubber aging and deformation. After roller replacement or polishing, pressure should be reset and test run to verify yarn traction condition. The pressure of each pair of rollers should keep consistent.

Operating environment affects roller aging speed. Oil mist and high temperature in workshop will accelerate rubber hardening. Keep surrounding yarn path clean to reduce oil and fiber residue adhering to roller surface. Regular cleaning removes surface oil and fiber debris during shift shutdown.

Common faults caused by poor roller status include unstable drafting force, periodic thick-thin spots on filament, fluctuating tension and rising end break rate. When adjacent spindles have inconsistent yarn quality, check rubber roller surface and pressure first. Many technicians adjust speed parameters repeatedly without checking roller wear.

Chenille feeding rollers undertake core yarn and staple fiber delivery at the same time. Surface wear of feeding roller will cause uneven staple fiber feeding quantity, leading to uneven pile density on finished fancy yarn. Chenille production line rollers need more frequent surface inspection.

When ordering rubber rollers, factory maintenance staff compare material wear resistance, heat resistance and oil resistance. New rollers are mounted on test spindles to track service cycle and yarn quality. Spare rubber rollers should be stored away from light, heat and oil pollution, to prevent premature aging before installation.

Preventive maintenance includes surface inspection, regular polishing, pressure calibration, cleaning and aging assessment. Maintenance records log roller serial number, polishing time, replacement date and spindle number. It helps judge the consumption rule and set reasonable replacement cycle.

After roller replacement or polishing, low-speed test run is required, observe yarn running and collect sample for physical test. Confirm no slip phenomenon before raising to full production speed. Scientific rubber roller management ensures stable traction, reduces drafting deviation and improves batch consistency of textured yarn.
