Introduction The ribbon slitting machine is a key equipment in the production process of thermal transfer ribbon, and its slitting quality directly affects the use effect of the final product. In actual production, uneven end faces of ribbon slitting machines are a common problem, which can lead to uneven ribbon winding, misalignment during use, and even broken ribbons. Therefore, it is of great significance to master the correction method of uneven end face to ensure product

In the production process of thermal transfer ribbons, slitting is a critical part of the quality and cost of the final product. The slitting machine tailings – the remaining parts of each ribbon that are slitted to the end that cannot be processed – have long been considered "necessary losses", but in reality, this waste has great potential. Let's start with a cause analysis and explore several practical ways to reduce tailings waste. 1. The root cause of tailings waste Ribb

In the production and processing of ribbons (thermal transfer ribbons), the slitting machine is one of the core equipment. However, many operators encounter a tricky problem – excessive dust when ribbon slitting. These fine dusts not only affect the workshop environment and threaten the health of operators, but also may reduce the accuracy of equipment and affect the quality of the finished ribbon. So, how to deal with excessive dust in the ribbon slitting machine? This artic

The slitting quality of hot stamping foil (electrochemical aluminum) directly affects the hot stamping effect and material utilization. If there are burrs, draws, dust or uneven edges after slitting, in addition to equipment accuracy, wrong tool type selection or improper use is often the core reason. This article compares the applicable scenarios of round knives and flat knives to help you make quick decisions based on the characteristics of hot stamping foil. 1. Diagnosis f

In the process of slitting foil stamping, foil breakage is one of the most common and headache problems. Frequent foil breakage not only leads to material waste, reduced production efficiency, but can also damage the tool die and machine components. Many operators often consider changing the foil brand or adjusting the tension first, but in fact, the blade angle and air pressure setting are the core variables that affect the frequency of foil breakage. 1. Why does the blade a

In the printing and packaging industry, the hot stamping process is favored for its ability to give products a high-end, exquisite metallic texture.
