Material is fed into the spiral spring by axial thrust and cen - trifugal force that is generated by high speed rotation of linear spiral spring , where , the material is pushed forward axially due to internal friction of the material and axial force of the spiral spring , thus reaching the conveyance purpose , and the conveyance height can be determined according to users " requirement 该机是通过绕性螺旋形弹簧的高速旋转所产生的轴向推力和离心力,将被输送的物料送入螺旋弹簧内,再由物料的内摩擦及弹簧螺旋的轴向力,将物料作轴向推移,达到输送目的,输送高度按用户要求确定。
Under a row of five coiled spring housebells a curvilinear rope , stretched between two holdfasts athwart across the recess beside the chimney pier , from which hung four smallsized square handkerchiefs folded unattached consecutively in adjacent rectangles and one pair of ladies grey hose with lisle suspendertops and feet in their habitual position clamped by three erect wooden pegs two at their outer extremities and the third at their point of junction 那是一排五个家用螺形弹簧按铃，下面，在烟囱那凹进去的间壁两侧的两个钩子之间，弯弯地横系着一根绳子，上面挂着四块对折的小方手绢：一块挨着一块，彼此并不重叠，呈长方形。另外还有一双灰色长统女袜，袜帮是用莱尔棉线25织的，脚脖子以下是通常的样式。
