涤纶胶片的接片方法已有大量的研究,以前也曾介绍过利用压敏胶带或介质加热进行接片。超声接片的原理是用超声能进行接片。设备试验用接片机(图1)可接合8、16、35和70毫米的胶片。超声换能器装置在支撑板A上,换能器锥顶与砧轴的间距由弹 There has been a great deal of research into the method of splice the dacron film and it has also been previously described that the use of pressure-sensitive tape or dielectric heating is applied to the splice. The principle of ultrasonic patch is to use ultrasonic energy for the patch. Equipment Test Laminator (Figure 1) can engage 8, 16, 35 and 70 mm film.
