摘要： Apparatus for cutting a tire into segmented pieces utilizes an even multiple of pairs of shear-cutting blades actuated by a hydraulic cylinder ram. The pairs of blades are arranged in radial symmetry, and each pair of blades comprises an upper blade and a lower blade, both of which have a cutting edge defined thereon, such that each pair of blades operates by action of opposed cutting edges. The lower blade of each pair is affixed to a frame, which may be trailer-mounted for mobility. The upper blade of each pair is affixed to a carriage movable on a track secured to the frame, and oriented with the cutting edge disposed at an acute angle relative to the cutting edge of the lower blade. Diametrically opposing upper blades are disposed at corresponding angles, and adjacent upper blades are disposed at different angles from one to the other. Thus, diametrically opposing pairs of blades function to simultaneously engage a tire for cutting and adjacent pairs of blades operate to sequentially engage the tire for cutting. As a result, less force is required to cut an ordinary automobile tire, or a larger tire may be cut with the apparatus.
摘要翻译：用于将轮胎切割成分段件的装置利用由液压缸柱塞驱动的成对的剪切刀片的偶数倍。成对的叶片以径向对称布置，并且每对叶片包括上叶片和下叶片，两者都具有限定在其上的切割边缘，使得每对叶片通过相对的切割边缘的作用而操作。每对的下部刀片固定在框架上，该框架可以拖车安装以便移动。每对的上部刀片固定到可在固定到框架上的轨道上移动的托架，并且其切削刃相对于下刀片的切割刃设置成锐角。直径相对的上叶片以相应的角度设置，并且相邻的上叶片以彼此不同的角度设置。因此，直径相对的叶片成对的作用是同时接合用于切割的轮胎，并且相邻的叶片对操作以顺序地接合轮胎进行切割。结果，切割普通汽车轮胎需要较小的力，或者可以用该装置切割更大的轮胎。
