Roll paper cutting machine!
What is slitting?
In recent years, with the vigorous development of China’s packaging industry, the slitting machines as a supporting component have played a crucial role in the slitting and quality control of packaging products.
Cutting is the final process in the wide-format paper production line or post-printing processing. It holds a very important position in the entire production process. It enables the production of products with the specifications required by users. Precise cutting and rewinding can ensure that the finished products have a good appearance and a proper roll state.
The current status of the slitting machine market
Currently, the use of slitting machines in China is divided into several stages. Among them, the first stage is mainly used for single slitting and is aimed at the slitting of wide-width raw materials.
The primary use of the one-pass cutting is for downstream processing enterprises. The secondary or tertiary cutting provided by the downstream customers is carried out by the one-pass cutting or three-pass winding paper cutting machines. The manufacturers of these machines are mainly the one-pass cutting manufacturers.
In recent years, as market competition has become increasingly fierce, in order to provide better services to downstream customers, slicing machine manufacturers have also adopted secondary slicing. Due to the unique specificity of slicing machines, each has its own advantages and development directions.
Therefore, only a cutting machine that can achieve the effect of secondary cutting can be called a “double-blade” cutting machine.
However, due to technical and manufacturing process issues, only a few companies in China are capable of producing dual knives. SMH Machinery is one of those manufacturers.
What is a double-edged knife?
Double knife, also known as “double knife roller type cutting machine”, is a device that uses two synchronous rotating knife rollers to cut the paper sheet, thereby dividing the rolled paper into flat sheets of the required size.

SMH Machinery launched its first generation of “double knife” technology independently in 2013. At that time, it attracted great attention from the paper industry and the printing industry. Everyone wanted to know – what were the distinctive features of this technology!
As of 2025, SMH Machinery will always showcase the “double-cutting tool” at both domestic and international exhibitions.
It has obtained the national intellectual property patent certification; it has been highly sought after and recognized by customers both at home and abroad; it is the new generation of roll paper cutting machine!
The advantages of double swords
The cut edges are smooth without any paper fibers. This process is completed in one step. There is no need for a secondary trimming step using the paper cutter, and the edges can be directly fed into the printing machine. This saves users’ time, reduces labor costs, and shortens the time for cost recovery.
Especially for the cutting of various paper sheets weighing more than 128g, the effect is even better, and it ensures stability and reduces waste.
