Abstract:

According to the 2016 East Marmara Paper Industry report, 812 000 tons of cleaning paper was produced in Turkey. Based on 3% production increase projection of the report, the production amount in 2020 has exceeded 900 000 tons. Industrial roll tissue papers constitute a large portion of the tissue paper types produced. They are extensively used in shopping malls, hospitals, factories, public and private company buildings and similar places where services are provided. Production lines that produce roll type industrial tissue paper make the tissue paper in the form of a bobbin ready for the end user. In this line; The semi-product tissue paper bobbin is turned into products called "log" in end-user usage diameter and bobbin width. The log products are sliced in an industrial roll type tissue paper cutting machine and brought to consumer size. Some of the critical problems experienced in the cutting-slicing processes are; unwanted strip tension, design of strip blade and sharpening system. The aim of thesis is to solve cutting-slicing problems for enhanced cutting quality and to increase efficiency of slicing process and strip life. Within the scope of this study, design, analysis and prototype manufacturing of the industrial roll type tissue paper cutting machine are realized. Autodesk INVENTOR 3D CAD program was used to design the machine and by static analysis was conducted by FEM and fit analyzes were performed on the same program. The results were compared with experimental studies conducted in the field environment and validity of them were proved. As a result, a machine with a productivity that is 20% higher than its peers, increased life of the strip by 17%, has been designed, analyzed and manufactured according to scientific principles. Two empirical formulations are developed to determine remaining strip life.
