DISPONIBILIDADE: melhoria mecânica para rebobinadeira de papel térmico

Abstract

This work addresses a case study on the availability of a thermal paper rewinder in a pulp and paper company. The objective is to analyze operational effectiveness, evaluate maintenance indicators and examine costs related to the equipment, with the aim of identifying opportunities for improvement. The results revealed a difference between total production and actual production, indicating efficiency problems; the indicators showed a high number of failures and corrective interventions. Maintenance costs, especially related to the transmission system, represented a significant portion of total expenses. The suggested improvement proposal consisted of modifying the current transmission system for pulleys and timing belts, aiming to improve availability, reduce costs and minimize maintenance time. However, an in-depth analysis is necessary to assess the necessary investment and develop a preventive maintenance plan.
