Binding has changed from manual to machine in the mid-1950s, and from single-machine to linkage in the early 1970s. Binding has entered the third equipment renewal stage since the founding of the People's Republic of China in the decade since the mid-1990s. Development, market needs and close to international standards. Its characteristic is that the linkage replaces the stand-alone machine, the new stand-alone machine replaces the old stand-alone machine, and the small and medium-sized linkage equipment increases to meet the needs of modern processing.
Among the various processes in the printing industry, the variety of binding equipment, models, and forms are at the forefront. According to incomplete statistics, there are about 140 kinds of machines used for binding, and the equipment of each binding process has almost no commonality. For example, there is no commonality between folding machine and collating machine, collating machine and stapler: there is no commonality between different types of staplers and staplers (iron wire stapler and wire-locking stapler); There is no commonality between them. Almost no senior binding technician can fully grasp the binding equipment.
In recent years, there has been a large increase in linkage production lines. At present, China's post-press processing production line equipment is basically complete, with a total of 5 production lines:
1. Wireless glue binding production line
There are hundreds of wireless binding binding lines (including small, medium and large) in the country, including dozens of large ones, mainly imported from Switzerland, Germany and other countries, and some are domestically produced. The output of large-scale linkage production lines is generally more than 6000 copies per hour, and the highest is 10,000 copies (Swiss Martini 5SF type); there are hundreds of small and medium-sized units (strips), and the output per hour is generally more than 2000 copies. Small and medium-sized linkages have more equipment made in China. More than 100 sets have been purchased in more than 400 binding factories in Sanhe City, Hebei Province. It can be seen that the utilization rate of wireless perfect binding equipment is quite large.
2. Linked production line for saddle stitching
There are nearly 1,000 linked production lines for saddle stitching in the country, most of which are domestic equipment, mainly including Shanghai Ziguang's 8C, 8D and other models, with an output of 5,000 to 8,000 copies per hour. [next]
3. Pingding linkage production line
Mainly refers to the linkage production line formed by ordering, wrapping, ironing (DBT-01 type) and collating. Due to the gradual elimination of iron wire binding, this linkage device is no longer an object of development.
4. Hardcover book linkage production line
There are more than 20 hardcover book linkage production lines in the country, mainly for the German Korbu period, followed by Swiss Martini and Italian production lines. Due to the increasing processing of hardcover books, in the past three years, China has introduced 10 German Korbusi production lines, of which the most advanced type 2000, can produce 50 hardcover books per minute, and the daily output is about 25,000. The adjustment operation is controlled by computer. Second is the compact 35, with an annual output of 2,000 copies and a daily output of 16,000 copies.
5. Linked production line of this book
This equipment is a kind of saddle stitching, flat back booklet linkage that is formed by linking dozens of processes such as marking, dividing, counting, matching cover, bookbinding, backrest, finished product, counting and dividing, output, etc. production line. At present, the only processing linkage line for this book in China is from the German Weir company. After normal operation, the output reaches 20,000 copies per hour.
There are many types of stand-alone machines for post-press binding. The main changes in recent years include folding machines and thread lockers. The folding machine has been changed from the usual full-blade type to the split-blade hybrid type in the past. For example, the imported Starr and the domestic H660 type are large-format equipment of international standards, which are suitable for modern use, fast speed, and high quality. Good and easy to adjust. The thread-locking machine is mainly domestic equipment, and some of the advanced equipment introduced can reach 160 posts per minute. Multiple matching signatures can be locked separately (up to four sets of pages can be locked). Although this device is expensive, it is very suitable for future development needs.
In addition to the major changes in the above two places, the order loading machine is also commonly used in page colliding machine, page binding machine, waxing machine, book binding machine, flattening machine, collating machine, wire stapler, glue brushing machine, hot stamping machine There are dozens of models, hundreds of models, such as printing machine, rounding machine, spine machine and book cutter. In short, the binding equipment is constantly updated with changes in technology and materials to meet the needs of modern processing.
