环形输送带是指平型输送带生产完成后，因为使用的环境或者条件限制，必须使用环形输送带时，会对平型输送带进行硫化接头(又称热粘)，使其变为环形输送带。
Annular conveyor belt means that after the production of flat conveyor belt is completed, when the annular conveyor belt must be used due to the limitations of the use environment or conditions, the flat conveyor belt will be vulcanized (also known as thermal bonding) to turn it into an annular conveyor belt.
环形输送带(环型输送带)是在生产过程中将输送带制成无接头环形输送带(环型输送带)，其特点是带芯没有接头，没有因接处早期损坏而影响使用寿命，胶带表面平整、张力均匀，因此胶带运转平稳，使用伸长率小。扭王块模具 高铁遮板模具 阶梯护坡模具 拱形护坡模具 卵形槽模具 保定室内设计培训 保定平面设计培训
Annular conveyor belt (annular conveyor belt) is a kind of endless conveyor belt (annular conveyor belt) made of conveyor belt without joints in the production process. It is characterized by no joints in the belt core, no impact on the service life due to early damage at the joint, flat belt surface and uniform tension. Therefore, the belt operates stably and has small service elongation.
环型输送带，环状输送带: 环形输送带系指生产过程已将输送带制成无接头的环形输送带，其带芯接头处强力可达到胶带本体强力的90%，胶带表面无明显接头缺陷，因此，胶带运输平衡，使用伸长小。环形输送带带芯用优质全棉或维棉交织帆布制成，一般2-6层或用NN-200型尼龙帆布(或聚酯 帆布)作强力层。
Annular conveyor belt, annular conveyor belt: the annular conveyor belt refers to the endless conveyor belt without joints that has been made of the conveyor belt in the production process. The strength of the belt core joints can reach 90% of the strength of the belt body, and there are no obvious joint defects on the belt surface. Therefore, the belt transportation is balanced and the use extension is small. The belt core of the annular conveyor belt is made of high-quality cotton or Uygur cotton interwoven canvas, generally 2-6 layers or NN-200 nylon canvas (or polyester canvas) as the strong layer.
