Q & A on binding process

how does the binding process calculate the completion of the task

answer: the number of processing tasks completed by the binding process (or workshop) is calculated based on the order number (1 order per 500 full sheets of paper), that is, multiply the total number of copies of a variety bound by the total number of pages of a book to obtain the total number of pages of the total number of copies, divide the total number of pages by the number of openings to obtain the total number of full sheets of paper, and then divide the total number of sheets by 500 full sheets of paper (1 order), to obtain the total number of orders of this variety to complete the task, That is, the total quantity of paper used to process a batch of working materials (or a variety)

why should the bookbinding process be prepared before processing

answer: post press binding is a very complex processing process. In order to ensure the smooth connection between the upper and lower processes in the whole processing process, a series of production activities between the processes are carried out in an orderly manner, and the functions of various works, including process technology, personnel, equipment and so on, are scientifically and reasonably organized and coordinated, so that dozens of process flows can be smoothly produced, All preparations must be made before binding processing

what preparations should be made before binding

answer: generally, the following preparations need to be done: (1) undertake production tasks and assign processing tasks; (2) Determine the way and method of processing technology; (3) Estimate work and materials; (4) Carry out normal processing according to the processing scheme: (5) mantissa work; (6) Complete the calculation of the task

how to undertake production tasks

answer: the undertaking task of binding process is undertaken according to the technical conditions of the unit, equipment capacity and the requirements of the publishing unit

after undertaking the task, the production management department should first carry out scientific and comprehensive process design according to the specifications, methods, methods and other requirements put forward by the publishing unit (or customer). For example, the prepress and printing processes should choose the correct typesetting and printing methods according to the different binding methods, and formulate the correct processing scheme and distribute it to all processes in the workshop

how to assign processing tasks

answer: there are many types of machines, types of work, and small processes in the binding process, so the cleaning after each use is very critical. There are many kinds of changes. In order to ensure that this complex process processing can be carried out in an orderly manner, and to ensure that the production task is completed on schedule, the production scheduling meeting is usually used when issuing the processing task. First of all, the production scheduling director of the binding workshop analyzes the processing scheme, determines the processing mode, method and processing steps according to the requirements, and then immediately holds the workshop production scheduling meeting, and arranges the tasks through the four links of the scheduling meeting

how to determine the way and method of processing technology

answer: before processing, according to the requirements of the processing plan, determine the processing methods according to the sequence of processes. For example, according to the loading method, opening number and materials of the processed books and periodicals, determine which ones are operated manually and which ones are operated by machines; According to the arrangement of the number of Posts and pages, whether it needs the bonding and inserting of scattered pages; According to the binding method, what kind of material is used, what kind of binding form is used, whether it is wireless or lockwire, whether it is hardcover or paperback, and whether the hardcover is rounded; How to process to connect with each other, etc

how to carry out the normal processing of the binding process

answer: normal production can be carried out after the mode and method of processing technology are determined. In general, starting from the first process of binding (post process), based on the processing scheme (or a sample book of unfinished products made in advance attached), process it step by step according to the process flow sequence. After the completion of each process, there should be clear numbers, such as the total processing quantity, the working hours, work quantities, materials, mantissa and whether there is a loss, etc., and the processing of a certain variety of books to be printed is completed After the numbers of varieties are complete and accurate, the processing scheme is completed, and then it needs to be filed as the basis for future processing

what is mantissa

answer: mantissa refers to the number of copies of a certain type of book that is not enough due to some reason, but the last number that needs to be remedied

what is the importance of doing the mantissa well

answer: the quality of mantissa work is not only related to the completion of the processing task of each variety of books and the accuracy of the employment letter cycle according to the plan, but also needs the support and guarantee of the new material industry. Moreover, the chemical composition used to measure the chemical properties of materials directly affects the reputation and capital turnover of the unit. Therefore, it is imperative to do a good job of mantissa work

how to eliminate mantissa? How to do the mantissa work well

answer: the best way to eliminate the mantissa is to start with the printed pages, and strictly control the number of each process and the emergence of waste products. When defective products and waste products appear in one process and are left to the next process to become the mantissa, you should immediately piece up the books or pages to make them qualified products, and complete the whole process of processing with a batch of books, so as to avoid delays and bad consequences
