日本很早就生产了普通帆布芯运输皮带,后来又生产一种强力人造丝纤维芯运输皮带,一九五六年则开始生产维尼龙芯皮带,皮带强度每平方厘米平均可达六百至七百公斤,最高的达一千公斤。一九六三年发展用钢丝作带芯,抗拉强度高达一万公斤,延伸率小、成槽弯曲性好。 Early on, Japan produced an ordinary canvas core transport belt, and later produced a powerful rayon fiber core transport belt. In 1956, it started producing Vinylone core belts with an average belt strength of 600 to 700 per square centimeter Kg, the highest up to one thousand kilograms. In 1963 for the development of steel wire core, the tensile strength of up to ten thousand kilograms, elongation is small, good groove bending.
