Beschreibung
Zusammenfassung:	A core metal insert is provided having a series, or multiple series, of laterally extending score marks in a non-reduced thickness portion, or portions, of the insert. Such score marks are provided in at least one face surface of the insert. The score marks provide stress relief so that when the corresponding precursor sheet, metal blank is lengthened to produce the insert, the resulting insert will have a lesser tendency to contract from its lengthened state. A method of providing such a core metal insert also is provided. L'invention porte sur un insert à coeur métallique présentant sur au moins une de ses faces une ou des séries d'encoches transversales de relaxation des contraintes. Ainsi lorsqu'on allonge la tôle lui servant de précurseur, l'insert résultant présente une tendance moindre à se contracter depuis son état allongé. L'invention porte également sur un procédé de fabrication d'un tel insert à coeur métallique.
