Tissue papers are an integral part of our daily lives. The required properties of softness, smoothness, even after a considerable amount of moisture has been absorbed, place special requirements on the manufacture of these papers.Softness is one of the most important product characteristics of tissue papers. Apart from this significant factor, there are other important quality characteristics such as absorbency and resistance to tearing. These properties are achieved as a result of the sophisticated paper making process, which begins with a well thought-out method for fiber preparation.Stricter environmental regulations are necessitating improvements in the quality of waste water and exhaust air, the efficient use of energy and a reduction in the consumption of fresh water.SIPAPER provides a unique overall package for setting up, expanding and operating production facilities for the manufacture of tissue papers.Uniform equipment design based on standardized SIPAPER solutions is the basis for a transparent and efficient production process without interfaces. Our solutions represent many years of experience and are matched to the standard solutions of mechanical engineering.
The pulps that are manufactured during pulping, need to be further treated in order to improve its physical properties. This pulp then undergoes mechanical treatment commonly known as refining. This unit operation is carried out in the stock preparation area of the paper machine. Fillers and auxiliary agents are added to the refined pulps and these pulp mixtures are temporarily stored in tanks. Thereafter the pulps undergo a series of cleaning, dilution and screening phases.Solutions with SIPAPER has developed advanced drive and process automation solutions for all the steps involved in the process. The Manufacturing Execution System (MES) is responsible for acquiring the production data and makes it available for further processing and material tracking; a high level of system availability is ensured by a range of services.
The tissue manufacturing process involves sheet forming, wet pressing, drying, and winding. In high quality tissue machines the drying will be realized by the TAD (Through Air Drying) concept, combined with the traditional Yankee cylinder.
Precision variable-speed drives, which are usually combined to form a network of sectional drives, provide the machines with the power they need; a large number of single drives are also required around the machine for pumps and fans.With SIPAPER Power the power supply to all process areas and the auxiliary systems are guaranteed. With the Process Control System PCS 7 the machine controls is realized, where SIPAPER Drives secures smooth operation of the sectional drives. Process controls can be optimized with SIPAPER DCS, while the MES Solutions enable optimized and efficient production control.Technical Services and Technical Support finally secure the required high availability in all process areas.
As a generic term for the processes that follow the manufacturing process, finishing covers various machine types and functions:
Calendar for smoothing
Winders for rewinding and cutting the roles
Sheet Cutter for cutting sheets from the roles
Packing machines for roles and sheets
Variable-speed drives whose interaction is coordinated by our SIPAPER Drives solutions ensure that the machines run efficiently and accurately. Order and material tracking as well as logistics processes are handled using MES solutions. The process is optimized by means of the SIPAPER DCS solution package. Last but not least, these state-of-the-art standardized solutions are complemented by our services and technical support in order to provide a high level of availability
In the pulp and paper industry, water is a vital production resource as well as a significant cost factor. As a process ingredient, it significantly affects the quality of intermediate as well as end products. Quality parameters such as printability, runability or cross section variances are directly related to wet-end chemistry and the water resource. What’s more, increasing water and energy costs and stricter environmental regulations make intelligent solutions in water management even more important – solutions that optimize the entire water cycle in your plant.
Increased production, reduced water usage, consistent qualitySIPAPER Water is a water management concept that bundles our expertise in the field of water supply and water treatment. For your facility, that means increased production volumes, reduced water consumption, and above all ensured consistent product quality.Water management is Energy ManagementWe combine recycling of rejects and biogas production with power generation to create a highly sophisticated energy concept. With this concept and our expert implementation, Siemens delivers real long-term economic advantages for your operation.
Electric power, steam and water are becoming ever more important factors in the pulp and paper industry. A high level of availability is expected, and this is what we guarantee with our SIPAPER Power and SIPAPER Water solutions. This applies both to new plants and to the expansion or modernization of existing plants. The advantage of these solutions is the consistency of the engineering throughout the mill, thereby achieving a uniform plant concept for generation, distribution and consumption.
SIPAPER Power includes the power management systems for energy import, generation and distribution, aimed at optimizing consumption and hence also costs.In the light of rising energy prices and obligations to limit emissions, reducing specific energy use is one of the priorities of every pulp and paper mill. To deal with this concern, Siemens provides support throughout the entire manufacturing process.

Alongside Corporate Management, Administration is usually home to all the activities and functions that are not linked directly to the production process. This is where information is aggregated, decisions are made, contracts concluded, data stored, as well as raw materials and production planned.
To be able to function efficiently, Corporate Management, Human Resources, Purchasing, Production Planning and the Project department require not only the right information at the right time and the right place, but also a suitable IT infrastructure in order to fulfill the demands made of them.
Siemens offers consulting and software solutions together with the appropriate hardware for all aspects of Administration. These include solutions for vertical and horizontal integration from production level to corporate level. The range of products and services is complemented by a large number of stationary and mobile telephone systems, communications networks, data servers, PCs and laptops to equip the IT infrastructure and ensure that it remains operational.
Warehouse: Mastering ComplexityProduction involves a wide range of different processes: Incoming materials, auxiliary agents and additives that have been delivered must be stored in the appropriate quantities at various locations. Semi-finished products, such as parent rolls, are stored temporarily before being processed further. Outgoing finished products must be picked for orders placed and then shipped. The types of warehouse and modes of transportation used are equally diverse: for example, woodyards, waster paper and high-bay warehouses, roll stockrooms, warehouses for bulk and ground storage, rack serving units, cranes, fork-lift trucks, etc.
