Crescent Former Tissue Machine

1. Overview

2. Working Principle

Formation Section

• The key feature of the crescent former lies in its unique paper - forming process. In this section, the pulp suspension is delivered onto a continuously moving forming fabric. At the same time, a second fabric, usually a felt, comes into contact with the pulp at a crescent - shaped area. This double - fabric arrangement helps in dewatering the pulp quickly and uniformly, which is essential for forming a consistent and high - quality tissue web.
• The dewatering process starts as soon as the pulp hits the forming fabric. The water is removed through the fabric by a combination of gravity and vacuum suction. The felt on the other side also assists in the dewatering process and helps to transfer the newly formed tissue web from the forming fabric.

Pressing and Drying Sections

• After the formation of the tissue web, it enters the pressing section. Here, the web is further dewatered by passing through a series of press rolls. The pressure applied by these rolls squeezes out more water from the web, increasing its dryness level.
• Subsequently, the web moves to the drying section. In most cases, a Yankee dryer is used in crescent former tissue machines. The tissue web is adhered to the large - diameter Yankee dryer drum, which is heated internally. As the web rotates around the dryer, the heat evaporates the remaining water, resulting in a dry and soft tissue product.

4. Advantages

High - Quality Product

• The unique forming process of the crescent former allows for the production of tissue paper with excellent softness, strength, and uniformity. The double - fabric dewatering helps in creating a more even distribution of fibers in the web, resulting in a tissue product that is gentle on the skin and has good absorbency.

High Production Efficiency

• These machines are designed for high - speed operation. With the continuous improvement of technology, modern crescent former tissue machines can achieve high production speeds, enabling manufacturers to meet large - scale market demands efficiently.

Energy - Saving Features

• Many crescent former tissue machines are equipped with advanced energy - saving technologies. For example, in the drying section, the Yankee dryer is designed to optimize heat transfer, reducing energy consumption while maintaining high - quality drying results.

5. Applications

• Household Use: Such as toilet paper, facial tissues, paper towels, etc. These products are essential for daily life, providing convenience and hygiene.
• Commercial and Public Use: In restaurants, hotels, hospitals, and other public places, the tissue products are used for cleaning, wiping, and maintaining hygiene.
