Abstract: Method of setting fire rings in gaskets according to which a metallic sheet is provided with holes having upstanding cylindrical rings dimensioned and positioned to register with holes in the gasket. Rings encircling these rims are then cut from the metallic sheet while retaining them in their relative position, the gasket is placed on the rings so that the rims project through the gasket holes, and the rims are pressed down against the gasket. The invention includes a machine which carries out all but the first of these steps successively and automatically.

Abstract translation: 在垫片上设置防火环的方法，金属片设置有具有直立圆柱形环的孔，其尺寸设置并定位成与垫圈中的孔对准。 然后将环绕这些边缘的环从金属板上切割，同时将它们保持在相对位置，垫圈被放置在环上，使得边缘突出通过垫圈孔，并且边缘被压靠在垫圈上。 本发明包括连续自动地执行除了第一步之外的所有步骤的机器。
