Abstract

Disclosed is a method for manufacturing bands, comprising the steps of: performing a first stretching to a pressed band-shaped material while heating at the same time to increase the stretching rate; performing a second stretching to the stretched material while heating at a higher temperature at the same time to cause further stretching of the band-shaped material, while the heating at a higher temperature allows softening and recovering of the surface textures of the band-shaped material whereas the strength of the material intermediate portion of the band-shaped material is increased due to increased density resulting from strain hardening occurring in the second stretching step; and knurling and rolling up the band-shaped material after the second stretching step.

Description

V. Description of the Invention (1) [Technical Field] The present invention relates to a process of sub-stretching and heating, f, a manufacturing method, especially a secondary method. The thinner and softer belt can be made. [Previous technology] As shown in Fig. 4, it is mainly used for the manufacturing process of a kind of packaging tape which is mainly used by the extruder 8 丄 2, and then The belt-shaped material 8 〇, ^ material (such as PE ding, etc.) is extruded into a belt shape, and then the shaped belt material = into a cooling water tank 8 2 cooling and stretching, and the stretching roller 8 = , 8 ^ Introduce a set of stretching rollers 8 3 for 8 4 pairs of v-shaped materials 802 two lines of technology while stretching the belt body, heated by a temperature of about 8 5 ° C ~ 10000c, order = heat In general, its heating temperature is about 2 to 5 times to form the desired # f 状 材料 80 0 can be stretched after being heated by a number of rollers 8 5, so that the belt material & f, and then the belt material The embossing is carried out around 80 embossing roller 86, and it is cooled at room temperature, and then introduced again. After being picked up, it is rolled up by the winding device 87. In the manufacturing method of Lishu, the phenomenon of strain hardening occurs. Therefore,-the material 80 will be stretched by "/ 5 times, more than 5 times of stretching. Very much /, the stretching ratio is only 2 Of course, strain hardening can cause the band material to break. Tensile strength, however, also relatively increases the f j degree and improves its flexibility. The material 80 is hardened and lowered. At the same time, the hardened band-shaped material 80 is increased in depth to make the depth of the embossing lighter and it is less noticeable because of the hardness @. Need to know 537964 V. Description of the invention (2), embossing is to enhance the surface friction of the strip-shaped material 80 surface protruding pattern, so that the packing machine can indeed drive the packaging belt to move or tighten the article. Therefore, the shallower the depth of embossing will make the pattern inconspicuous and reduce the surface friction force, making it difficult for the strapping machine to surely drive the packaging belt to carry out the operation of packing items. The state of the tissue, and the resulting effect should be after stretching. This hair material can reduce the originality of the material and make the surface friction after the belt is stretched. The aforementioned effect] The main manufacturing method is originally made by a hardening of the belt material that can be re-physical properties. It is necessary to improve the manufacturing method of the belt body and the next packaging tape. The purpose is to solve the above-mentioned problems and provide a plastic stretching of the strain-hardened band material due to the secondary stretching and the secondary stretching of the higher temperature at the same time; and the heating at a higher temperature can make the band material surface and The chemical properties return to the structure near the softer middle part before processing, which will increase the strength due to the increase in the density of the material after the second stretching, so that after the two can be thinner and softer at the same strength It is because the thin and light belt body after the second stretching has the same strength, so the manufacturing cost can be reduced. The purpose of the embossing operation of another material table is to restore the higher heating temperature surface tissue to a softer state during the second stretching, so that the second time, it can produce obvious uneven patterns to increase its surface. Another object is the material group after secondary stretching
