Motor Drive Shaftless Mill Roll Stand
High-Capacity Dual-Arm Motorized Reel Stand for Rapid Core Loading, Axial Calibration, and Constant Web Tension Control
The Golden Brand Heavy-Duty Motor Drive Shaftless Mill Roll Stand is an essential high-efficiency foundational block for automated corrugator single-facer configurations and complex multi-ply board manufacturing lines. Built entirely without cumbersome traditional central mounting mandrels, this unit employs two independently mobile, high-tensile structural steel clamping arms driven by synchronized internal gear motors. Operators can seamlessly elevate, clamp, center, and release massive kraft paper jumbo reels with simple electronic control panel commands, maximizing plant safety benchmarks while slashing reel setup down-time.

Important maintenance and operational milestones for Motorized Shaftless Mill Roll Stands
Traditional stands require crew members to manually drive a heavy structural steel core shaft through the paper roll center before winching it onto the frame. This shaftless design utilizes two independent, symmetrical motorized arms that slide directly into the roll core from both ends. This dramatically speeds up changeovers, minimizes manual lifting injuries, and reduces operational downtime between reel changes.
The machine is engineered with integrated dual-disc multi-point friction brakes on both arms. We supply this setup with either an accurate pneumatic pressure regulator matrix or a rugged manual adjustment wheel system to maintain steady back-tension, preventing web snapping or sagging as the reel diameter decreases.
The system is equipped with independent gear-motors to execute four primary axis functions: structural clamping of the core, opening/releasing the arms, vertical lifting/lowering of the mill reel, and simultaneous right-left lateral tracking adjustments to fix web alignment on the fly.
This heavy-duty design handles large-format rolls up to a maximum outer diameter of 1500mm, with standard width span configurations ranging dynamically from 1400mm up to 1800mm to match standard production deckles.
Yes. On demand, we supply the roll stand with ground tracks and a heavy-duty mechanical transport trolley. This allows operators to stage the next kraft paper roll outside the active zone and slide it smoothly into position between the open clamping arms.
