The endless conveyor belt (ring line conveyor belt) flat conveyor belt production is completed, because the use of the environment or conditions, you must use an endless conveyor belt, flat conveyor belt vulcanization connector (also known as hot sticky) so that it becomes an endless conveyor belt (ring line conveyor belt). The tape core joint strength can be up to 90% of the strength of the tape body, no significant joint tape surface defects, therefore, the endless conveyor belt transporting balance, using small elongation. Endless conveyor belt the (circular conveyor belt) with a core made of canvas with high-quality cotton or dimensional cotton interwoven, generally 2-8 layers or strong layer of nylon canvas (or polyester canvas). The Company may be produced according to customer needs proper length, width and thickness of the common type, heat-resistant (≤ 180 ℃), cold type (not less than -40 ° C), acid and alkali resistant type, high temperature (no higher than 200 ℃) and the endless conveyor belt. Annular sidewall conveyor belt means the production process has made conveyor belt loop without joints, the joints of the tape core strength can be up to 90% of the strength of the tape body, no significant joint tape surface defects, therefore, the balance of tape transport, The use of small elongation. Annular sidewall conveyor belt with a core made of canvas with high-quality cotton or Victoria Cotton interwoven, 2-6 layer or as strong layer NN-200 nylon canvas (or polyester canvas). ? The annular sidewall conveyor length and limit deviations: endless conveyor belt length m the limit deviation mm length less than the length of 15 ± 50 15-20 ± 75 lengths greater than 20 with long ± 0.5%
