Postpress Technology 1000 (614-627)

614. What is the operating procedure of the slot machine?
A: The operating procedures of the press machine mainly include the following points:
(1) Make all preparations before using the slot machine, such as preheating and adjusting the temperature, setting the rules, etc.;
(2) During the correct processing, the quality, temperature, and pressure of the pressure groove must be checked at any time to ensure that the appearance of the post-press booklet meets the requirements.

615. What are the operating procedures of the hardcover linkage production line?
A: The hardcover linkage production line is generally composed of 13 units. Its operating procedures mainly include the following:
(1) All preparations must be done before starting the machine, such as rough inspection of individual machines, adding lubricating oil, etc.;
(2) Starting from the book block feeder, adjust the rules of each stand-alone machine according to the required specifications;
(3) Store the adhesive in advance and preheat it so that the viscosity is appropriate;
(4) According to the conditions of the rules, the various kinds of binding materials required are stored in advance and used;
(5) After completion of the preparation work, a signal will be sent, and the operation will be carried out on a single point and the connection will be made. If there is no error, then the signal will be sent. The linkage line can operate normally.
(6) In the normal operation process, each single machine should closely cooperate with each other. If any problem is found, it will be signaled to stop and be processed. Afterwards, the signal must be sent first to ensure the safe production of the linkage line.
(7) Wipe the equipment and clean the glue pan on time. Under normal operation of the equipment, one or two shifts shall be checked once every two weeks. The glue pan shall be cleaned once a month or with the wiper.
The maintenance of the equipment used for the binding of the post-press, the minor repairs shall be resolved during the erasure of the equipment, and the intermediate repair and overhaul shall be advanced by the senior engineer or the technical personnel responsible for the equipment, and shall fill in the maintenance report and report to the equipment department or the factory. The director of the equipment responsible for maintenance shall wait for approval before proceeding with maintenance, and shall be followed by the senior engineer or above. After passing the inspection, the two parties shall sign and approve it before they can test production.

616. What are the working procedures for the binding of books and books?
Answer: The binding of books and books includes the work processes of book block processing and book closure processing.

617. What is the working process of book block processing?
Answer: The working process of book block processing refers to the processing process from the printed pages, including the processing of page crash, blanking, folding, slippage, page matching, and bookbinding. Booklet but does not wrap the cover.

618. What is the process of book closure processing?
A: The process of book closure processing refers to cutting the printed cover into

The required specifications, through the paste, hot stamping, polishing, laminating and other processing, packaging the work process outside the book block.

619. Book binding including the installation method?
Answer: The binding of books and post-press includes six kinds of methods, including hardcover, paperback, saddle stitching, ancient thread, butterfly and luxury.

620. What is the working process of the page crash?
Answer: There are two kinds of mechanical and manual collisions. The mechanical page collision is to loosen one sheet of pages with both hands, allowing the sheets to penetrate into the air, and then using mechanical vibration and pressure pad to collide with the original irregular sheets. Neatly; manual page collision is based on artificial shaking loose sheets, the original irregular neat page collision, there are two types of shock-type and impact.

621. What are the requirements for a miss-pager operation?
Answer: In the case of a miss-type page-flipping operation, pick up 1/3 or 1/4 of a ream of paper, pinch the sheets diagonally or on both sides of the sheet with both hands, bend it upwards and lift it up, so that the sheet goes in between The air, aiming at a corner, rubs back and forth between the palm and the tiger's mouth, and the number of shifts is neat and tidy. When a page breaks, one hand presses on one side of the paper basket and the other hand presses on the sheet to push the air out to complete the process of misoperation.

622. What are the requirements for a collision-type collision operation?
Answer: In the collision-type collision operation, both hands pick up a stack of sheets, pinch the two diagonals into the air, and then hold the two sides to stagger the stack of paper until the collision occurs. In the event of a collision, the hand must loosen the sheet and must not pinch the collision so as not to cause the curled edge to collide.
Whether it is a miss-move type or a bump-type page-fighting operation, the pages of the delivery should be relatively aligned (to be neat) when they are completed. Each page must be marked and distinguished, and must not be randomly placed.

623. What is the work process for material cutting?
Answer: The process of cutting materials is to select the blade, determine the method of cutting, and open the material.

624. How to use the blade?
Answer: The paper cutting machines used for cutting materials are single-sided paper cutters, and their specifications vary. There are various types such as full-opening, split-opening, and four-opening. The length of the blade is the same as that of the paper cutting machine. One of them can be selected according to the size and requirements of the processed paper.

625. How to determine the blade α angle?
A: The blade α angle is determined according to the paper thickness, paper quality, and the height of the paper cut. That is, the most suitable blade α angle is selected based on the cutting force of the cut paper roll. The smaller the blade α angle, the sharper the blade, the smaller the cutting resistance of the object to the cutter, the wear and power consumption of the cutter will also be reduced; the larger the blade α angle, the cut object to the cutter The greater the shear resistance, the higher the cutter wear and power consumption. However, the effect of cutting is very different. The former has a smooth but not durable incision, while the latter has a smooth but durable cut. Therefore, the angle α of the blade that can achieve smooth and durable cutting is generally selected to be 22 to 24°.

626. How to determine the opening method?
Answer: The correct cutting of paper is the key to opening materials, which is related to the accuracy of books and periodicals and the quality of processing in the next process. Therefore, 1 according to the requirements of the construction plan, careful analysis of the layout design, check the product name, opening number, booklet, etc.; 2 determine which of the material selection method should be used to open the material; 3 calculate the number of copies; 4 before the material can be Take a sheet of paper, fold it or mark it.

627. How to open materials?
Answer: After one hit sheet (usually one order), adjust the back gauge according to the determined method, size, or painted mark. Place the paper stack on top of the back gauge and side gauge. Do not cut it until it is finished. The cut paper baskets are checked for compliance and stacked neatly on the paper table.
