643. How to use folded board when folding manually?
Answer: The material of the folded board (referred to as the folded board) is made of bamboo and plastic. It is rarely made of metal plates, and its length should be determined by the size of the folded sheet. Generally, 3 to 40% of the commonly used folding plates have a length of about 250 mm, and a folding plate having a length of 150 mm and a width of about 30 mm can be used as a folded book page. Both ends of the flap are rounded (to prevent loose-leafing) and the panel surface is smooth and smooth.

644. The vertical cross method manual folding two fold page how to place?
A: The vertical cross-folding method is 4 pages and 8 pages when the two-folding page is folded manually. The maximum or minimum page number is placed below the left-hand top page, as shown in Figure 1.

645. Vertical cross method manual folding three fold page how to place?
A: The vertical cross method is manual folding of three folds. It is 8 pages and 16 pages. Place the largest or smallest page number underneath the left hand (rest) under the sheet.

646. How does the vertical cross method manually fold the four-fold page?
A: The vertical cross method is a 16-page 32-page manual folding of four-fold pages. The position of the swash plate is set to the maximum or minimum page number below the second page of the page below the left hand (rest).

647. What are the operational requirements for manual folding?
A: 1 First place a stack of pages and then test it first to check whether the adjacent page numbers of the folding sheets are correct or not, and whether the layout order is correct. After the trial folding is correct, the normal folding can be performed; 2 After each folding, the page number is aligned To keep it pressed, the flaps are solid, no wrinkles, tight creases, and no gaps; the signatures after 3 folds are piled up neatly, and after folding (500 sheets), they must be bumped and flattened. Both ends of the pad are tightly packed and stacked on the designated paper table.

648. What are the methods of manual sticking?
A: There are two ways to manually stick a page: one is sticky and one is sticky, and the other is sticky and sticky with a “sequential” method.

649. How to stick pages manually?
A: First, prepare the two versions of the signatures that need to be glued, and then pick one of the single or double-page signatures. After hitting it, open it and reveal the sticky mouth (3mm). Apply the adhesive and put it on the ground. The sticky mouths of the adjacent signatures are neatly glued together to form a complete post.

650. How to manually "continue" sticky page operation?
A: First, prepare the two editions of the signatures that need to be glued, and then pick up one or two pages of the signatures (approximately 20 to 30 sheets) into a fan-shaped one. Inside the signature. After the completion of the insertion, it should be leveled and bumped, and then use a brush with an adhesive to apply adhesive along the sticky joints. After sticking it, press it gently and press it firmly. Complete the manual "renewal" page sticking operation.

651. How to set up the manual, insert operation?
A: First, prepare the two editions of the books that need to be inserted and inserted in order, and mark them on the joints of the joints of the set, inserted single, double pages or charts, etc. for inspection purpose. Open the book with one hand, pick up the other adjacent set of needs and insert the signature in the other hand, insert the two sets of books and insert them together into a thick one, and then use it for the next procedure.

652. What are the operating requirements for adhesives, sleeves, and inserts?
A: 1 Before the operation, check whether the order of the two adjacent signatures is correct. 2 Correctly select the adhesive. The sticky mouth remains in compliance with the quality standards, and there are no phenomena such as sticking, sticking, sticking, or sticking. 3 The sequence of inserts and inserts is correct. There are no set errors, wrong insertions, missed sets, missing inserts, multiple pages, etc.; 4 sticks, sets, and well-inserted signatures are all required to be self-checked. Paper on the table.

653. Which part of the folding mechanism is divided into?
A: The folding mechanism is divided into two parts: the paper feeder and the folding machine.

654. There are several forms of paper feeder?
Answer: There are two kinds of pneumatic feeders and pneumatic platforms.

655. What is the working process of the air bag conveyor?
Answer: The working process of the air bag conveyor is composed of the platen roller (pressure ball, pressure roller), pressure claw (wire clamp), air nozzle, feeling piece, delivery roller (suction belt), and paper feeding. The work of the rollers, etc., is connected to complete the paper feeding work.

656. How to carry out the paper loading operation of pneumatic air bag feeder?
Answer: Pneumatic ring-type paper feeder adopts manual operation. When operating, one page is picked up and checked for errors. After hitting, it is placed on the loading table and the paper edge is opened by a certain distance. After the board is full of sheets.


657. What are the operational requirements for loading pneumatic air bag feeders?
Answer: 1 Before loading paper, check whether there are any mistakes in the process, such as the white version, running version, folding angle, etc., and check the page number of the layout. Correctly load the paper according to the order; Or too small, the general spacing is 2 ~ 3mm, in order to ensure that the paper smoothly reaches the folding part.

658. What is the working principle of pneumatic air bag feeder?
A: Using the continuous and constant rotation of the transfer roller, the leading edge of the sheet is sucked up and moved forward with the rotation of the roller; the sheet of paper passes between the feed shaft and the rubber guide roller, and the air path is opened. After being put down, the friction drive is brought to the conveyor belt until it is conveyed to the front flap position of the first fold of the folding section, or is conveyed to the oblique conveyor roller, thus completing the working process of the pneumatic wrapping machine.

659. What is the working process of the pneumatic platform feeder?
A: The working process of the pneumatic platform paper feeder is mainly divided into two parts: paper loading and paper feeding. The collision paper is stacked on the paper table and directly loaded into the paper feeding table according to the folding order. The pneumatic suction is used. The paper or paper blowing method feeds the sheets one by one to the folding section.

660. How to carry out paper loading operation of pneumatic platform type paper feeder?
Answer: When the paper is loaded, the paper stack is directly pushed onto the pneumatic platform type paper feeding device, and the paper stack lifting device lifts the paper pile up to the center line of the conveying roller so that the leading edge of the paper stack touches the limit switch. At this time, the paper stack Stop rising automatically.
