仙人球的介绍摘要：An improved coiled brush strip for a rotary broom of the type which might be ud in a street sweeper. The broom generally compris a cylindrical core and a coiled brush strip with the ends of the brush strip being cured to the opposite longitudinal ends of the core to curely tighten the brush strip upon the cylindrical face of the core. The brush strip includes a metallic channel element which receives a plurality of cloly bunched, radially extending bristles throughout its length. The underside of said channel element, which engages the cylindrical face of the core, is provided with spaced protrusions which act to slightly space portions of the channel element from the core face. Thus, when the brush strip is tightened upon the core, the channel element can be distorted into engagement with the core and thereby spring-loaded about said protrusions so that it will remain in tight gripping engagement with the core even if there is slight looning movement at one end of the coiled brush strip as, for example, upon removal of a sweeping load.
