帆布叠层芯输送带生产工艺技术，近二十年有了较大的改进和提高。上世纪90年代我国引进了德国辛拜尔坎普公司生产的具有合幅拼缝功能的帆布叠层芯输送带定张力成型机，是我国帆布叠层芯输送带成型工艺上的一个重大革新。同时，一些生产厂家先后采用了具有相应功能的国产设备，例如恒张力多层复合成型机、定中心恒张力多层一次贴合成型机等，逐渐改变了我国输送带成型工艺落后的状况，进而提高了帆布叠层芯输送带的内在和外观质量水平。此外，进口和国产鼓式硫化机、大长度平板硫化机、高精度四辊压延机、连续硫化设备的应用，也为我国高强力帆布叠层芯输送带的发展创造了条件。 The process technology of the belt conveyor belt conveyor belt has been improved and improved in the past two decades. Introduced in China in the 1990 s Germany simba bair kemp company which has the function of close picture flat-fell seam canvas laminated core conveyer belt tension molding machine, molding process is the canvas laminated core conveyer belt on a major renovation. Some manufacturers have adopted, for example, at the same time has the corresponding function of domestic equipment, such as multilayer composite forming machine, centering of constant tension constant tension multilayer laminating machine and so on, gradually changed the status of conveyor belt molding process behind in our country, and improve the internal and exterior quality of canvas laminated core conveyer belt. In addition, the import and domestic drum length of vulcanizing machine, vulcanizing machine, high precision four roll calender machine, the application of continuous vulcanization equipment, as well as the development of our country high tenacity canvas laminated core conveyer belt.
