Title
(EN) ARTICLES COMPRISING PROTECTIVE SHEETS AND RELATED METHODS
(FR) ARTICLES COMPORTANT DES FEUILLES DE PROTECTION ET PROCÉDÉS ASSOCIÉS
Abstract
(EN)
Methods of the invention include those for applying protective sheets to articles. According to these methods and resulting articles, a protective sheet is applied to at least a portion of an exterior surface where protection is desired on an article. At least one portion of at least one exterior surface of the article to be protected can be integrally formed in the presence of the protective sheet. Improved bonding of the protective sheet to the article and improved processing efficiency are advantageously achieved according to the invention.
(FR)
La présente invention concerne des procédés comprenant ceux permettant d'appliquer des feuilles de protection à des articles. Selon ces procédés et les articles obtenus, une feuille de protection est appliquée à au moins une partie de la surface extérieure où une protection est souhaitée sur un article. Au moins une partie d'au moins une surface extérieure de l'article à protéger peut être formée intégralement en présence de la feuille de protection. L'invention permet d'obtenir de manière avantageuse une adhérence améliorée de la feuille de protection à l'article et une efficacité de traitement.
