How do MoveRoll Braking Pads increase safety in paper mills?
Over 150 paper mills worldwide now use MoveRoll braking
pads in many different applications, to reduce the speed of the rolls
in the finishing line. The Braking Pad is a simple and innovative roll
speed reduction solution.
The MoveRoll Braking Pad is designed on the basic principle
of reducing kinetic energy of the incoming roll. The combination of
soft material, air exhaustion, and absorption of kinetic energy can
reduce roll speed up to 0,5m/s or can, under certain circumstances,
even stop rolls completely. Reduced roll speed means minimal roll
bouncing and significantly shorter settling times. Depending on the
length, the portable Braking Pad consists of a certain number of
cushions and can easily be placed on flat surfaces. The product
design and soft special materials ensure gentle contact with the
roll and no damage is incurred either on the roll or the roll handling
equipment. Reduced roll speed and decreased roll bouncing
significantly increases in operator safety, as well as the minimization
of manual roll pushing. Notably, in high-speed applications such as
Winder Decks, the combination of a MoveRoll Zero Energy Receiver
and MoveRoll Braking Pad achieves the greatest increase in work
safety.

How does the MoveRoll Braking Pad work?
The Braking Pad is made of thin cushions which are
designed to be positioned on the rolling surface and to stay in place
without any attachment. The kinetic energy is reduced by special
soft material placed inside the braking pad, and air that exhausts out
of the braking pad as the roll weight squeezes.
The Braking Pad is placed on the floor as seen in (fig 1a.)
acting as a barrier to reduce the speed of the paper roll. When
reaching the Braking Pad, the paper roll goes over, initially collecting
air on the front end of the pad which will later be realised from the
exhaust ports on the back of the braking pad (fig 2b.) When the air
exhausts from the pad’s front, at the same time it causes counter
pressure on the back which results in speed reduction or stopping
of the roll. When the roll has left the surface of the pad, the inside
special material returns to its previous form and is ready to handle
the next roll (fig 3c.)
The MoveRoll Braking Pad is feasible for various roll
handling applications. For example, paper mills can place Braking
Pads in front of slat or chain conveyors to slow down roll speed
and reduce roll settling time. Similarly, Braking Pads are useful on
different sections of ramps, to slow down roll speed before the rolls
