A tool ring (1) for securing blanks in a machine of the type comprising a pair of rotating rings whose opposite, plane side faces are formed with a plurality of holding tools (8, 11) so adapted that an oblong blank (16) can be secured substantially radially between a pair of holding tools in respective ones of said rings. At least one ring has a groove (4) which is adapted to receive holding tools and spacer tools (9, 10, 10', 12) of which at least the holding tools have a convex face (23, 33) to engage the engagement face (19) of said groove. The holding tools (8, 9, 11) are mutually spaced by the spacer tools, and some of the spacer tools (10, 12) are positioned in the groove, while the position of the spacer tools is defined by the cooperation between edge faces (24, 25, 30, 31) on the tools. |
