Three-Roll Nonwoven Calendering Machine

The three-roll configuration adds an extra nip point compared to two-roll systems, improving bonding quality and surface smoothness in a single pass.

Achieves a roll surface temperature uniformity of ≤±0.65°C through a peripheral deep-hole heat exchange structure and closed-loop temperature control, resulting in a cross-machine basis weight deviation of ≤±2.5 g/m².

A servo-hydraulic loading mechanism allows for stepless linear pressure adjustment (0–110 N/mm), while a roll-crossing fine-adjustment mechanism (0–30 mm stroke) compensates for roll deflection.

The inclusion of an intermediate roll enables dual-sided treatment, making the machine suitable for products requiring high surface quality on both the front and back sides.

The heavy-duty frame undergoes complete stress-relief annealing, and G0.8-grade dynamic balancing ensures stable operation at rated speeds.

Nonwoven products requiring high surface finish and thickness uniformity, such as premium filtration materials and automotive interior substrates.

Applications requiring dual-sided surface treatment, where consistent surface quality is needed on both the front and back of the fabric.

Production of medium-width (≤3600 mm) specialty nonwovens where surface quality is a key differentiator.
