摘要： A comminution device having replaceable blade assemblies which are used, preferably, as stators. The blade assemblies can be replaceably affixed to the housing of the machine when used as stators or may be replaceably affixed to a rotating arm when used as rotors. The blade assemblies are comprised of a plug member that may have threads on part of its outer periphery in order to be threadedly connected to a stationary housing or rotatable member of a machine. A slotted portion is formed in the plug member and one end of a cemented hard metal carbide blade is disposed in said slotted portion. A collar is shrunk fit over the periphery of the slotted portion and provides the clamping force necessary to hold the blade in assembled relation to the plug member. Tapering cooperating elements of abutment are provided between the walls of the slot and the sides of the blade in order to urge one end of the blade into firm contact with the bottom of the slotted portion.

摘要： A method and apparatus for removing tread from tires preparatory to retreading of the tires in which a tire is mounted on a support and inflated and rotated on the axis of the tire. The tread is removed from the tire by a cutter disc which has cutting elements mounted thereon in an annular path with the annular path being presented to the periphery of the tire. The cutter disc and tire are moved relatively to cause the annular path of the cutter disc in which the cutting elements are mounted to traverse the tire from side to side and in a single pass across the tire the tread is removed therefrom. The relative movements between the tire and the cutter disc are under the control of a cam so that the proper contour is imparted to the periphery of the tire. The cutting elements mounted in the aforesaid annular path of the cutter disc are in the from of sharp edged discs of hard material which take clean chips from the tread of the tire thereby avoiding heating of the tire or the cutting elements and, likewise, eliminating smoke and dust that normally accompanies the removal of tread material by the use of a cutting device employing rasp elements therein.
摘要翻译：一种用于从准备翻新轮胎的轮胎中除去胎面的方法和装置，其中轮胎安装在支撑件上并在轮胎的轴线上膨胀和旋转。通过具有安装在其上的切割元件的切割盘从轮胎上将胎面从轮胎上移除，环形路径呈现在轮胎的周边。刀盘和轮胎相对移动以使得其中安装有切割元件的切割盘的环形路径从一侧到另一侧穿过轮胎，并且在穿过轮胎的单次通过中，从其移除胎面。轮胎和切割盘之间的相对运动处于凸轮的控制之下，从而赋予轮胎周边适当的轮廓。安装在切割盘的上述环形路径中的切割元件位于硬质材料的锋利边缘盘中，其从轮胎的胎面采取干净的切屑，从而避免轮胎或切割元件的加热，同样，消除烟雾以及通常使用在其中采用锉刀元件的切割装置来除去胎面材料的灰尘。
