New blanket ready before machine

The blanket consists of a surface layer and a base fabric, and is divided radially and horizontally. Since the extension of the blanket after the radial force is smaller than the transverse direction, the radial direction in which the expansion and contraction amount is small must be taken as the force direction of the blanket, that is, the radial direction of the blanket coincides with the circumference of the drum. When the blanket is cut, all four sides should be at right angles, and the diagonal line should be equal. In this way, the blanket can be evenly distributed on the roller to ensure product quality. At the same time, the bite of the blanket and the two ends of the tug are punched separately. The position of the hole should be on the same horizontal line, and there should be no height to prevent the blanket from being skewed.

When the new blanket is installed on the machine, it should be tightened first, and then check the blanket for wrinkles and air bubbles. If there is no problem after the inspection, tighten the roller after pressing the pressure several times. The new blanket has good elasticity and good stretchability. Tensile blankets should be gradually carried out. It is required that the tipping and the bite of the mouth should be performed at the same time. Do not apply tension on one side. Each time it is tense, it will wait for 3 to 5 minutes to pressurize and pressurize, so that it can be tightened several times. After the blanket has been tightened, we should also visually or manually stroke the blanket to check if the blanket and its cushioning material are flat, whether there is unevenness caused by the ink, paper, etc., and handle it in time.

Before the new blanket is put on the machine, the thickness of the desired pad should be determined according to the specific thickness, uniformity, elasticity, etc. of the blanket, and the number of liners should be determined with a micrometer. Over-thick gaskets will cause greater pressure between the blanket and the plate, affect the printing quality, make the imprints thicker and more distorted, and the dots will expand, and it will cause premature damage to the blanket. In addition, it will also speed up the printing plate. Graphic wear.
