The production steps of paper straws are divided into four main parts: paper holder, gluing, paper roll, and slitting.
The paper holder is the first part of the paper straw machine. After the first roll of paper is used, the spare roll is automatically switched on to ensure the continuity of the process and realize fully automatic production.
Gluing is the most important part of the production of paper straws. To ensure the safety and cleanliness of gluing, we need to pay attentions within work. After gluing, it is the rolling process, that is, the paper will roll into the shape of a straw in this process. The inner diameter of the straw can be adjusted between 3.8mm and 11.3mm. After the straw is formed, it will enter the cutting process. The length of the straw can be adjusted between 45mm and 1600mm.
