2 The first back book adhesive is not wet;
3 After the manual rounding, no self-calibration was performed;
4 Machine is not properly adjusted when the roller is round;
5 After the machine rounds up, the book block jolts on the linkage line. 1 When you make a round by hand, you should start the book 2/3 and then make a round;
2 The book back glue should be moistened before it is finished, making the book back soft and easy to shape;
3 Manually knead the book core after hand-rounding to correct the circular potential and verticality;
4 correctly adjust the clamping degree of the roller according to the thickness of the book block;
5 less downtime can reduce the bumping time of the book block on the linkage line. 2. When the ridge does not protrude from the ridge and rises by hand, the position of the lower hammer is incorrect or the ridge height is too small;
2 The ridges are not properly applied and the ridges cannot protrude;
3 When the machine is ridged, the spacing between the wedge and the back of the book is not suitable, or the arc length of the wedge does not match the length of the book back arc. 1 When raising the hand manually, the position of the lower hammer should be in the middle of the spine, and the force should be on both sides. When the force is applied, the hammer should be pulled first. Both hard and soft, when the book is folded on both sides and then ridge, do not rush to calculate the ridge;
2 When the machine is ridged, the wedge should be in contact with the back of the book to press the back of the book and allow it to deform out of the ridge;
3 The arc length of the wedge should be based on the book thickness. 3. After the book was opened, the front of the book was opened with a terraced shape and there were too many folds in the signature, and the paper was too thick;
2 selected coated paper;
3 The circle is too big. 1 books that need to be rounded, the number of signatures should not be excessive, under normal circumstances, paper with a basis weight of 50g/m2 or better must not be folded at 40%;
More than 25% off the coated paper signature is best not to make a round;
3 扒 circularity should be 90 ~ 120 °, if the circular potential is too large, the front port is easy to show terraced. 4. After the book was cut, the air in the booklet was not completely eliminated. The book pages were wavy and the book pages that were wavy after cutting were straight.
2 When the manual folding, not suppress the book block began to scrape, leading to crease run empty, the page warping uneven, resulting in the air inside the signature can not be discharged;
3 The sewing thread is too large and the thread is too thin, causing the book page to move after being cut;
4 Do not make a round when the book is too thick. 1 When the machine folds, it is necessary to adjust the sliding knife correctly to ensure that the air in the signature is completely eliminated;
2 When manually folding, press down on the book block and then level it to ensure that the book is folded flat and compacted;
3 Sewing machine needles are best to use fine needles to avoid the book pages running out due to the large gap between the diameter of the needles and the diameter of the needles.
4 Books with a thickness of 20mm or more are best made into round backs. Do not use them as a square back, because the square back will cause the front mouth to spit out pages when it is read. 5.扒 扒 扒 扒 书 书 书 书 书 书 书 书 书 书 书 书 书 书 书 书 书 书 第一 第一 第一 第一 第一 第一 第一 第一 ; 1
2 uneven coating, there are missed parts;
3 Aging adhesive, broken after coating;
4 improper use of ridges or rounds;
5扒 The cracks appear when the back of the book adhesive is not wetted. 1 It is forbidden to use flour paste and other plant adhesives as hardcover book adhesives, and glues of bone glue or synthetic resins in animal glues can be used.
2 In the case that the adhesive's strength and viscosity are all qualified, the application should be thin and uniform, and the amount of glue should not be too much or too thick;
3 Do not use expired or aged adhesives;
4 When the ridges are used with force, they must be light and heavy;
5 should be wet when the book is back, not dry. 6. Adhesion plug cloth after the two ends of the hair or bent, wrinkled, not stiff 1 Cloth is too soft, not stiff;
2 Manually sticking the head cloth does not tighten, compact, stick firmly. 1 The plug cloth purchased must first be diluted with a thin adhesive and dried before use;
2 When sticking the head cloth, the book block should be compacted first, and then the plug should be tight and sticky after compaction. Book closure processing including shell and hot stamping two parts 1. The rounded corners of the book shell are not smooth after cornering.
2 too few creases in the corner;
3 After the plug angle is not compacted. 1 can be used oblique, long handle, not sharp metal knife (such as students with a pencil sharpener, etc.), or use the thumb nails to manually plug the corner, can also be used angle machine plug angle;
2 The more creases behind the plug angle, the better, but not less than 50%;
3 After using a hand-plug angle, use a wooden hoe to pry the horns and flatten them. 2. The surface of the book case has blisters after drying. The reasons are as follows: (1) Improper selection of paste adhesive;
2 Aging adhesives, no bonding ability;
3 uneven or missing coating when applied. 1 It is necessary to choose a binder with low water content, high viscosity, and strong bonding force. It is forbidden to use plant pastes such as flour pastes;
2 It is forbidden to paste the book shell with aging adhesive;
3 Applicator should be suitable when applying adhesive, full, no spill, no flowers and no leakage;
4 There is no need for tearing and reworking due to empty foam on the surface of the shell, and can be filled with medical needles. First, the needle is used to inject the adhesive after the blister is punctured, and the advancing glue is pushed flat and pushed by hand, and then scraped evenly with a scraper, and the excess adhesive is scraped off and wiped. 3. Book shells after hot stamping paste version (hot stamping graphic illegible) 1 hot stamping version of the temperature is too high;
2 stamping pressure is too large;
3 The hot stamping version is too thin, and the hot material is hard and thick. 1 According to the hot stamping material and the hot material, adjust the hot stamping temperature correctly;
2 According to the hot material and the actual situation, select the best hot stamping pressure;
3 According to the hot material to determine the hot plate thickness, the thinnest is 1.5mm. 4. Book shell stamping after the flower version (hot stamping after the end of leakage, not hot parts) 1 hot stamping version of the temperature is too low;
2 stamping pressure is too small;
3 Hot Stamping Material and Bonded Material Does Not Meet Requirements. 1 According to the hot stamping material and the hot material, adjust the hot stamping temperature correctly;
2 Hot stamping pressure should be determined according to the material to be hot stamped, the minimum pressure on the hot object is 10.3mm;
3 Fine adjustments can be made when the hot stamping temperature is too low or the stamping pressure is too low. 5. The hot stamping material is not hot or it is peeled off after hot. 1 The hot stamping material is not in conformity with the material to be heated;
2 Hot stamping temperature is too low;
3 hot printing plate is too thin, hot stamping pressure is too small;
4 stamping material itself has no binding ability. 1 According to the right choice of hot stamping material;
2 According to the hot stamping material and the hot material, adjust the hot stamping temperature correctly;
3 According to the texture and thickness of the object to be heated, determine the appropriate hot plate thickness and hot stamping pressure;

Four corners of the hot stamping surface (hot stamping on the edge or hot stamping) 1 When the hot stamping version is not firmly bonded on all four sides;
2 hot stamping area, hot stamping pressure;
3 hot stamping material is too soft, too many hot stamping. When printing on a hot stamping plate, it is necessary to corrode the back of the hot stamping plate and grind it with coarse sandpaper first, and then stick the knotted paper edge of the gap and then bond it. The hot stamping plate with good adhesion will be compacted. After sticking and then use, pay special attention to the four sides of the adhesive;
2 The larger the hot stamping area, the greater the hot stamping pressure. When the hot stamping full-page large-format imprinting, the hot stamping pressure and hot stamping temperature should be increased (slightly higher than 5 °C);
When hot stamping large-format bookcases, the hot stamping version should use copper (red copper) instead of zinc, because the red copper's transmission, heat dissipation and elasticity are better than that of zinc, and it is more durable than zinc, so red. Copper is best for large-format graphics and mass stamping. 7. Hot stamping (no hot stamping) not secure 1 Hot stamping temperature is too low;
2 stamping pressure is too small;
3 Hot stamping time is too short;
4 hot stamping version is too thin. 1 hot stamping hot stamp printing plate temperature can not be too low, generally only 5% to 10% lower than the temperature of the hot material (because hot stamping time is longer);
2 The hot stamping pressure should not be too small. It should be determined according to the material to be hot-pressed, so that the imprinting can be clear, and it can be firmly and without paste version;
(3) The hot stamping time is slightly longer than the hot stamping time for hot stamping and is generally doubled. If the hot stamping time is about 0.7 seconds, the hot stamping time should be 1.5 seconds. about. After the coupling process, including sleeve, pressure slot shape, lining, pressure equality. The three sides of the shell after the hatching inconsistent 1 book shell material specifications and the size of the booklet does not meet the size;
2 cutting size error exceeds the standard;
