Filed: 1989-06-20
Abstract: PURPOSE:To produce a self-adhesive sticker without the necessity for die cutting or removing unnecessary parts of the sticker by printing characters, patterns, etc., on an exposed surface of a metal foil with an acid- or alkali-resistant, solvent-resistant ink and etching and removing the metal foil of those parts where characters, patterns, etc., are not printed with an etchant. CONSTITUTION:Characters, patterns, etc., (M) are printed on an exposed surface 11 of a metal foil 2 of a self-adhesive sheet 1 with an acid- or alkali-resistant, solvent-resistant ink 12. After the ink 12 is cured, the self-adhesive sheet 1 is immersed in an etchant, e.g. an aq. NaOH soln., to remove the metal foil 2 of those parts where characters, patterns, etc., (M) are not printed. After the etchant 3 sticking to the self-adhesive sheet 1 is removed, the sheet 1 is immersed in a solvent, e.g. toluene. Thus an adhesive 6, a film 4, and a self-adhesive 9 of the parts corresponding to the removed metal foil 2 are removed, forming the essential parts 13 of a self-adhesive sticker comprising only the parts of the characters, pattern, etc., (M) with a metallic gloss. A weakly self-adhesive application tape 14 is laminated onto the surface of the characters, patterns, etc., (M) to complete a self-adhesive sticker 15.

Abstract: PURPOSE:To obtain a flat cutting face at all times by pressing a movable cutting edge toward a normal direction after slightly pressing said edge toward a direction different from a cutting direction when a rod material is inserted in the holes of fixed and movable cutting edges and cut with the shift of the movable cutting edge. CONSTITUTION:After a rod material 3 has been inserted in the through-holes 1a and 2a of a fixed cutting edge 1 and a movable cutting edge 2 for contact with a stopper 4, a piston rod 15a is contracted, a spacer 16 is drawn out and another piston rod 11 is pushed up, thereby pressing the movable cutting edge 2 upward. According to the aforesaid constitution, a shear force works between the fixed cutting edge 1 and the movable cutting edge 2 and a lead crack is generated on the rod material 3. Then, a ram 5 is lowered for hammering the movable cutting edge 2 and cutting the rod material 3. In this case, a crack due to pressing by the ram 5 propagates toward the lead crack as already existing. Therefore, the final shear force is small and a cutting face is clean, thereby improving cutting accuracy.
