Application of carrier rope in paper machine

The Role of Carrier Rope on Paper Machine

Carrier rope, also known as paper transfer rope, plays an important auxiliary role in paper machine operation, improves paper feeding efficiency, reduces manual operation risks, and is an important guarantee for the continuous operation of paper machine.

What is Carrier Rope

Carrier rope is made of high strength synthetic fiber and is usually used in the drying section, pressing section and other links of paper machine. It runs around multiple pulleys to form a closed loop. It is used to help the paper web to be smoothly transferred from one section to the next section after the paper web is formed, especially when the paper machine is started and the paper web is broken, reintroducing the paper web to the drying section and subsequent processes.

Workflow of Carrier Rope

During normal production of paper machine, paper web needs to continuously pass through multiple stages such as pressing and drying. Due to the complexity of each stage, it is difficult to achieve reliable transmission only by the tension of the paper itself, so carrier rope intervention is required.

When the paper web enters the drying section, the head of the paper web is inserted into the carrier rope. The carrier rope will run at the set speed, bring the paper web to the specified position, and the paper web will break away from the carrier rope and enter the next process. The carrier rope will continue to circulate and prepare for the next paper break.

Carrier Ropes are Commonly Used in Paper Machine Parts

The drying section is the most widely used part of the carrier rope. The water evaporation intensity of the paper web in the high temperature drying cylinder is low and it is easy to deviate or break. The carrier rope ensures that the paper web is stably attached to the surface of the drying cylinder and smoothly guided to the next device through continuous operation.

In the pressing section, the carrier rope will help the paper web pass through the high pressure area to prevent breakage due to insufficient tension. It can quickly complete the threading of the paper web and improve the start-up efficiency.

Sun Hong's DuPont dead carrier rope is suitable for long term high speed operation. The high temperature drying environment can withstand frequent tension and impact to maintain a stable running path and is not easy to slip or jump. Common carrier ropes include: solid carrier ropes and hollow carrier ropes.

Maintenance and Matters of Carrier Ropes

In order to ensure the stable operation of the carrier rope of the paper machine, daily maintenance cannot be ignored.

(1) Regularly check whether the pulley is worn and replace old parts in time.

(2) Be careful to avoid rope jams caused by dust and debris.

(3) Pay attention to reasonable tension adjustment.

For paper mills, a stable and reliable carrier rope product is a key step to ensure continuous and stable operation of paper machines and reduce unplanned downtime.
