Shoe press belt for ef昀椀cient tissue production
Atrobelt – has been designed for all kind of
paper, board and tissue machines. High sheet dryness
after the shoe press is a key factor to achieve a high
machine speed and ef昀椀ciency. Additionally, many paper
quality parameters can be in昀氀uenced by the shoe press
concept and the shoe press belt technology. Most of
the tissue shoe presses are equipped nowadays with
press belts having continuous grooved designs. The
combination and interaction of the advanced press felt
(Atrojet.T / Atromaxx.T) and shoe press belt (Atrobelt)
technology can be the key success factor, when the
runnability of the paper machine are tuned to maximum
ef昀椀ciency. A major improvement of the new Atrobelt
is superior mechanical resilience and void volume
retentions which enable an effective dewatering and a
higher life.
It is Heimbach’s aim to select the optimal belt
design for your shoe press demands from the variety
selection of Atrobelt groove patterns.
The innovation of our paper machine
clothing´s will not stop here as our Heimbach product
development team are constantly progressing our
machine clothing technology forward.

Atrobelt
•
Valuable selection of high-quality polyurethanes, unique embedded reinforcement structures.
•
Smooth surfaces promote low 昀氀ow resistance and provide ef昀椀cient drainage for high dry contents.
•
Excellent void volume retention of the groves.
•
Increase mechanical strength and improve dimensional stability in machine direction.
•
Highest resistance to cross machine direction and crack formation.
•
Excellent resilience to chemicals and temperatures.
•
Low hydrolysis to prevent swelling.
•
Great stretching and recovery ability.
Atrojet.T
•
Fine and homogenous base structure ensures 昀椀rst
class drainage as well as speedy start up curve.
•
Modular batt structure helps to provide a 昀椀ne-pored
structure. This prevents accumulation of dirt on the
surface which helps achieve high paper quality.
•
The felt allows perfect saturation which in turn
leads to ef昀椀cient hydraulic nip pressure.
•
Higher contact area and good uniformity across
the felt width result in ideal nip and pressure
distribution to the Yankee cylinder.
•
Open structure on the roll side means ef昀椀cient felt
cleaning and cleaner machine run.
