SHAFTLESS HYDRAULIC MILL ROLL STAND(MRS—V4)
SHAFTLESS HYDRAULIC MILL ROLL STAND
A swing-type hydraulic shaftless mill roll stand that clamps, positions, and lifts two mill rolls per stand by hydraulic control — built to feed your corrugated roller machine line without a manual roll change.

A SWING-TYPE STAND BUILT AHEAD OF CORRUGATED ROLLER MACHINE
The MRS-V4 hydraulic shaftless mill roll stand holds and unwinds the base paper roll that feeds the single facer — the first station ahead of the corrugated roller machine.
Hsieh Hsu has engineered wet-end stations for corrugated roller machine lines since 1980. The MRS-V4 is our swing-type stand: each stand carries two pairs of arms, holding two mill rolls at once, with open-close clamping, left-right positioning, and lifting-lowering all driven by the hydraulic system.
Each mill roll stand runs on two sets of tracks and dollies, and a 7-1/2 HP hydraulic power unit drives the clamp, position, and lift functions. A manually adjustable air brake keeps unwind tension consistent up to the 1,500 mm max. paper diameter, and a choice of jugged (toothed) or bulgy (expansion) chuck fits the stand to your roll cores. For plants that need to move rolls further or want finer tension control, the MRS-V4 can be configured with an optional hydraulic railway and hydraulic lift-up, or an imported multi-point brake.
SWING-TYPE DESIGN, HYDRAULIC FROM CLAMP TO LIFT
From roll clamping to tension control, the MRS-V4 hydraulic shaftless mill roll stand is built so one operator can run a roll change alone — keeping your corrugated roller machine fed without interruption.
SWING-TYPE, TWO-ROLL STAND
Each MRS-V4 stand carries two pairs of arms, holding two mill rolls at once — the next roll is already staged when the running roll runs out.
FULL HYDRAULIC CLAMPING & LIFT
Open-close clamping, left-right positioning, and lift-lowering of the arms are all driven by the hydraulic system — no manual cranking.
7-1/2 HP POWER UNIT
A self-contained 7-1/2 HP hydraulic power unit (1 set) drives clamping, positioning, and lift independently of the rest of the line.
MATCHED CYLINDER SET
Two ⌀100 × 450 mm ST clamp cylinders and four ⌀63 × 700 mm ST lift cylinders, sized and paired for balanced clamp and lift force.
AIR BRAKE TENSION CONTROL
Manually adjustable pneumatic braking holds consistent unwind tension as the roll pays out, up to a max. paper diameter of 1,500 mm.
TRACK & DOLLY MOUNTED
Each stand runs on two sets of tracks and dollies, with a choice of jugged (toothed) or bulgy (expansion) chuck to match your roll cores.
