Traction Rollers | Friction-Driven, Tension-Controlled, Multi-Format Label Feed Core Components

Traction rollers are the core drive components of a labeling machine’s web handling system. Typically configured as a rubber-coated roller paired with a metal idler, they use friction to precisely pull the label liner (or carrier web) through the peeling plate. Their performance directly impacts labeling accuracy, speed stability, and material compatibility. They deliver high transport stability: active friction-driven design prevents slippage, jamming, or skipped labels, ensuring perfect synchronization between web feed and applicator motion. The rubber surface offers high coefficient of friction (μ≥0.6) and exceptional abrasion resistance—capable of millions of cycles without degradation. Precise tension control: works in tandem with the unwind brake to dynamically regulate web tension—absorbing startup shock to prevent breakage and maintaining consistent tension during operation to avoid wrinkles, misfeeds, or label overlap. Broad compatibility: supports label widths from 20–300mm and thicknesses of 0.05–0.2mm, suitable for round, flat, and other container types. Modular design enables quick changeovers for frequent SKU switches. With fatigue-resistant metal cores and oil/aging-resistant rubber coatings, traction rollers support 24/7 high-speed operation with minimal maintenance—truly the “power engine” behind reliable, high-performance labeling.
