Abstract: A method or producing rollers and sleeves for chains, particularly for roller chains or sleeve-type chains. The rollers and sleeves are of cylindrical form and they are deep-drawn from a sheet metal material. The drawn components can remain attached to the sheet metal for convenience in transporting them and later separated from the sheet as they are needed. Alternatively, the drawn components can be separated from the sheet metal material and can be pressed into the openings that remain in the sheet metal, again for convenient transportation.

Abstract translation: 用于链条的方法或生产用于链条的滚子和套筒，特别是用于滚子链或套筒型链条。 辊子和套筒是圆柱形的，它们是从金属片材料深拉的。 拉伸的部件可以保持附着在金属板上以方便运输它们，并且随着它们的需要而与片材分离。 或者，拉拔的部件可以与金属板材分离，并且可以被压入残留在金属板中的开口中，以便于运输。
