(54) Steel plate shearing installation


(57) 57 A steel strip shearing installation includes in series a pay-off reel for unwinding a steel strip therefrom, detectors for detecting defects and pin holes on the steel strip, a shearing machine for shearing the steel strip into predetermined sizes, a piling apparatus for piling the sheared and classified strips, and others. According to the invention, the installation comprises bridle rolls between the detectors and the shearing machine for exerting tensile force on the steel strip sufficient to maintain it in a horizontal position without its slack or upward or downward movement, thereby improving the accuracy of detecting defects on the steel strip and eliminating errors in measured length of the steel strip and therefore enabling electromagnet rolls at branching points of belt conveyors of the piling apparatus to be correctly operated in good timing to ensure the classification of acceptable and unacceptable products.
