tissue machine clothing
HHeimbach’s
is ready for the next challenge
Uwe Berg, Product Manager Tissue, Heimbach
INTRODUCTION:
Keeping in mind the market for tissue, how can our proven clothing design make a difference? How can we sustainably support our
customers to optimise challenges such as a reduction of energy consumption and carbon footprint while keeping the manufacturing cost as
economical as possible? These and many other topics are regularly addressed by our expert group including our sales engineers, product
managers and product development organisation.

Innovative tissue clothing
Machine technology, especially press technology has
constantly changed in recent decades, with a higher focus on energy
ef昀椀ciency, sustainability and decarbonization. As the mechanical
energy used in the press to extract water from the paper web is
substantially less than the thermal energy needed to dry a sheet
over the Yankee, any extra dryness from the press will translate into
reduced cost of manufacture. With our tissue clothing concepts,
we offer papermakers the possibility to optimize and sustainably
improve the performance of their machines by 昀椀ttingly in line forming
fabric, press felt and shoe press belt options.
Sustainable sales, product management and development
support
New paper machine clothing’s are primarily developed for
better performance, for example reduced energy consumption or
rather carbon footprint CO2, better utilisation of furnish as well as to
optimise machine ef昀椀ciency or paper quality. The 昀椀rst step of a paper
machine clothing expertise is to transfer what has been seen plus
spoken into sustainable knowledge and to use digital technology to
combine what has been learned into the product development for
the current requirements of the tissue machine. Arti昀椀cial intelligence
(AI) supports us in mastering daily challenges.
The advanced Home service & TASK parameters, as well
as in-house data, help us to realise design developments for the
complex requirements of the tissue machines to be able to offer
the best 昀椀t clothing concepts for the individual machine position.
The optimisation of the felt design is customer-target-oriented. Pore
size and pore distribution in the felt structure controls dewatering
capacity and start-up curve. In addition to the optimal modi昀椀cation
of the felt design, it must be checked that the shoe press belt design
works hand in hand with the press felt designs to achieve best
possible inlet dry contents at Yankee cylinder. The tissue forming
fabric design applied is based on an intensive study of the paper
requirements and difference in furnish and processing. Tissue
forming fabrics are judged upon 昀椀nes and drainage capacity. Very
short drainage lengths and high speed require thin, 昀椀ne and “open”
fabrics.
