Y-Type Three-Roll Uniform Nonwoven Calendering Machine

The Y-type three-roll configuration provides two sequential nip points within a compact space, enabling progressive bonding and improved heat transfer efficiency.

Roll surface temperature uniformity of ≤±0.65°C is achieved through a peripheral deep-hole heat exchange structure and a closed-loop temperature control module.

A servo-hydraulic loading system allows for stepless linear pressure adjustment (0–150 N/mm) and a roll-crossing fine-adjustment range of 0–30 mm.

The Y-shaped arrangement guides the fabric through two successive nip points, improving bonding uniformity and surface smoothness compared to single-nip configurations.

A maximum line speed of 800 m/min combined with 150 N/mm linear pressure accommodates both high-speed production of lightweight materials and the bonding requirements of heavier fabrics.

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

Premium hygiene nonwovens, such as topsheets for diapers and feminine hygiene products, which demand high standards for surface smoothness and bonding uniformity.

High-speed production of SMS and spunlace nonwovens, where line speed and surface quality are critical performance indicators. In process scenarios requiring consolidation via a single-pass, two-stage hot rolling operation, progressive heating helps improve bonding strength and the hand-feel of the fabric.
