Jumbo Press Roll

Paper Machine Jumbo Press Roll

Jumbo Press Roll engineered for pressing in high-speed paper machines, our High-Performance Jumbo Press Roll utilizes a large diameter design (up to 1500mm) to significantly expand the nip width. By increasing web dwell time in the pressing zone, it maximizes water extraction while operating at lower peak hydraulic pressure. This prevents sheet crushing, preserves paper bulk, improves wet-web tensile strength, and drastically cuts steam utility costs in the dryer section. Built upon heavy-wall forged alloy or high-strength iron cores, our Jumbo Press Roll delivers unmatched structural stability under extreme linear nip loads.

Key Features

Extended Dwell Time & High Dewatering: Large-diameter geometry expands the nip width, allowing longer pressing time for maximum moisture removal without damaging sheet bulk.

Extreme Load Capacity: Heavy-duty core design withstands intense linear nip loads up to 350+ kN/m, without bending deflection, securing a uniform cross-machine moisture profile.

Low Peak Hydraulic Pressure: Reduces hydraulic shock in the press zone, preventing wet-web crush and prolonging press felt service life.

Advance PU/Rubber Cover Topologies: Available with plain, blind-drilled, or grooved polyurethane (PU) and synthetic rubber covers for optimal water venting and high wear resistance.
