Abstract: By shot-peening, shots having almost spherical shape are impacted against a surface of a portion of a metal-product, the portion being one which is to be subjected to sliding action. The shots have a hardness higher than that of the metal-product. By the shot-peening, the surface of the metal-product is heated to a temperature higher than a predetermined temperature and very small concave portions, each having a circular arc-shaped cross section, are formed due to the impact of the shots. As a result, the structure of the surface layer of the sliding portion has high internal stress, high hardness and high toughness. Further, since very small concave portions are formed on the surface of the sliding portion, the surface tension of lubricating oil is not decreased and a stable oil film can be formed. In addition, the surface retains high hardness and toughness, even if sliding is performed for long time periods, and the concave portions are not deformed so that a stable oil film can be maintained.

Abstract: Sheet-metal blanks are fed in succession one immediately after another to a rounding apparatus in which they are plastically deformed into a curve in a rounding mechanism and are given a desired constant bending radius. The portion of the blank initially running out of the rounding mechanism in the natural rounding position is deflected by guide means under elastic deformation out of the rounding position into a transfer position which is different from the rounding position and is thereby elastically deformed so that the portion of the blank running out of the rounding mechanism is kept under stress. When the end portion of the sheet-metal blank leaves the rounding mechanism, it springs into the transfer position due to said stress, leaving the way clear for another sheet-metal blank, which can already be in the process of being rounded before the fully rounded sheet-metal blank is ejected from the rounding apparatus and conveyed away.

When the piston is forced to move longitudinally in either direction, the groove slides over the guiding members to force rotation. The apices of the wave-shaped groove are either contoured or provided with a gating structure to assure that the guide members do not backtrack but instead move in one direction through the groove.
