Abstract
The leather goods industry demands high precision in adhesive application to ensure product quality, durability, and aesthetic appeal. This study focuses on the modification of adhesive application equipment to achieve precise glue deposition on leather surfaces, particularly for narrow strips with unglued edges. The research analyzes existing adhesive application methods, proposes structural modifications to rollers and nozzles, and evaluates the economic and technical efficiency of the modifications. The proposed modifications include the incorporation of channeled rollers and profiled nozzles to ensure accurate glue application while minimizing adhesive waste. Experimental results demonstrate a 15–20% reduction in adhesive consumption and improved product quality. The findings provide practical recommendations for leather goods manufacturers aiming to enhance production efficiency and product standards.
