TAD Paper Machines: Precision, Efficiency, and Leading Innovations in Paper Processing for Varied Applications and Superior Quality in North America.
TAD is a tissue production system: In order to improve the quality of tissue paper, hot air through-drying (TAD) technology was developed to minimize paper web extrusion. This process technology allows the wet paper sheet to be sucked onto a structural fabric that gives the paper a three-dimensional structure. The paper web and structural fabric are then transferred together to a large perforated roller, while hot dry air with a temperature of up to 350° passes through the structure. fabric and paper web to achieve the purpose of drying the paper web.
TAD paper machine is a specialized equipment used for paper processing, with its operation based on precise mechanical design and advanced optical detection technology. The main components of this equipment include the input device, processing device, control device, and output device. The input device is responsible for feeding raw paper into the machine, the processing device performs various operations such as cutting, folding, and flattening, the control device ensures the machine's operation and processing precision, and the output device delivers the processed paper.
The advantages of TAD paper machine lie in its high precision, efficiency, low noise, and user-friendly operation. These features make TAD paper machines highly popular in the paper processing industry, suitable for various production environments like printing factories and packaging plants. Its applications range from creating manuals, promotional flyers, to magazines, making it efficient and precise for both small studios and large printing facilities.
In North America, the TAD paper machine is renowned for being the highest quality and most expensive sanitary paper machine, particularly known for producing soft household paper. It is predominantly used in the domestic product sector, constituting approximately two-thirds of the overall North American household paper business. The Andritz PrimeLine TAD paper machine is equipped with 2 or 3 layers of dilution water-controlled stock chests and an optimized C-type double-wire former. Further dehydration is achieved through vacuum assistance before the paper moves to the TAD drying section, where specific quality and structure are attained through vacuum and speed differences during paper transfer. The paper is subsequently continuously dried to 75-90% dryness and supported by a fully welded stainless steel structure in the TAD drying drum. The entire hot air system has been developed and designed by Andritz's North American colleagues in Canada using Computational Fluid Dynamics (CFD) analysis. The paper is then transferred to the Yankee cylinder for dry creping before being rolled with the assistance of a stabilizer and a center-driven reel.
In summary, TAD paper machines, with their sophisticated design, outstanding performance, and widespread applications, have established a leading position in the paper processing industry.
