Paper cutting process

The preproduction and further development trend of the paper-making process-economic processing has been developing rapidly and continuing in the process of prepress and printing. The rhythm of technological innovation has been accelerating. The printing equipment of yesterday has been continuously advanced and has better performance. Replaced by quality and higher productivity equipment. Can process and cut 15000 copies or more of prints per hour. Increasing print productivity means that more material needs to be handled and handled. Polar has kept pace with the development from the very beginning - from the constant modernization of the paper cutter to the latest integrated computer controlled cutting machine. In addition, Polar also recommended a smooth production process, using a material processing peripheral system. At the last Drupa 2000 exhibition, Polar launched a new set of products. They are both complementary to existing equipment and also serve large-scale label production including complementary products that improve the performance of high-profile production equipment. Polar's products include the following equipment; Cutters, from the smallest Polar 66 t to 176, that is, from 66 cm to 176 cm in width. Peripheral equipment for material handling Paper lifter Paper roll elevator Paper picking Machine equipment Cushioning stacking equipment Automatic loading and unloading of paper Loading equipment Transportation system Complete paper cutting system Complete paper cutting system consisting of the above components Trademark labeling systems include on-line conveyors, die-cuters, die cutting, and tying equipment. Pile Turners palletizing equipment Stack turning machines Generally speaking, cutting is a simple work process, but with the great progress of industrialization, In the field of paper processing in the printing industry, the traditional process has also undergone tremendous changes. Printing opportunities and bookbinding machines have gone through several generations of stacking from tape-controlled cutters to the latest microcomputer-controlled cutting systems. Research and development have resulted in new cutters and cutting system equipment with high cutting accuracy, strong cutting capacity and high throughput. In just a few years, there have been cutting machines with color display, full image operation guidance, visual processing and computer-assisted cutting of external programming and editing of production data. The purpose of all these improvements is always to make the cutting process more economical. The result is higher production per process and shorter lead times. Here are some important aspects of the cutting process. 1, material preparation 2, cutting process 3, loading paper and unloading paper 4, further processing requirements 5, requirements for employees. Explanations: 1. Cutting material preparation - including paper inspection or quality control, including quantity quantification, and paper alignment (centering - that is, regular gripping process alignment). 2, the cutting process process - including the actual cutting operation, the programming operation method can be completed manually, automatically or can also be carried out at other work stations away from cutting. In addition, it also includes automatic programming of the machine room, which can be supplemented with a help plan for material handling on the machine cutter table or paper cutter. The necessary choice of machine cutters depends on the requirements of the specific cutting job process. It is becoming more and more important to reduce the waste of cutting under the conditions of industrialized high-scale production. 3, Cutter loading and unloading capacity. The process can be manual or automated. Depending on the volume of the material, the paper can be loaded on the table through the front or back side of the cutter cutter. Depending on the required work flow, paper can be discharged on the left or right side of the machine cutter. 4. Requirements for further processing Cutting paper is not always the final stage. Often, materials are transported to another place for further processing. The cutter can therefore be linked to the next station to shorten the entire production cycle. 5. Requirement for Employees Choosing who works next to the paper cutter is very important for productivity and efficiency. Many people cannot ensure maximum production. The important thing is how to arrange a person who has knowledge and ability, and is equipped with a combination of appropriate equipment and suitable equipment. After focusing on these cutting processes, the following prerequisites for efficient cutting are easy to understand: 1. High-performance paper cutter 2, cutter-oriented options for application orientation 3, high-quality cutting Cutting tool (knife and good grinding knife device). 4, suitable processing equipment (peripheral equipment) 5, good preparation of materials before cutting 6, arrange qualified personnel in the material handling positions. Due to the special structure of the printing industry, the size, production line, and printing process of the printing company are all different and other characteristics. The paper cutting machine manufacturers must provide various grades of paper cutters with different levels of automation. . There are two Polar cutters with very special electronic controls available in two models, available in 7 sizes. They all use a dedicated electronic control system to meet the needs of various art and graphic printing industries. The corresponding cutting lengths of the Polar cutters are 66, 78, 92, 115, 137, 155 or or 176 cm. The models of the cutters are Polar E and Polar ED. The Polar E-Eltromat is the basic model for general cutting operations. It is programmable, has 128KB of storage capacity, and is approximately equivalent to approximately 12000 cutting positions.
