A low-profile sheath (10) for protecting elongated items (24) is disclosed having a pair of substrates (12, 14) formed from flexible thermoset sheet material with opposite edges paired together to position the substrates in overlapping alignment. One pair of edges is flexibly attached together by a hinge (22) allowing the substrates to pivot between an open and a closed position for receiving and capturing the items. The substrates are corrugated. The hinge is formed from a plurality of thinned sheet regions which alternate between being oriented in the plane of the sheet and perpendicular to it. The alternating orientation reduces the imbalance of shear stiffness between the hinge connected edges and the free edges of the substrates. An apparatus for forming the sheath having intermeshing gears with beveled teeth and facing edge surfaces is also disclosed.
Cette gaine mince (10) destinée à protéger des articles de forme allongée (24), est constituée de deux substrats (12, 14), faits d'une feuille de matière thermodurcissable dont les bords opposés sont jumelés afin d'aligner les substrats. Deux bords sont reliés de manière flexible par une articulation (22) permettant aux substrats de passer d'une position ouverte à une position fermée afin de se saisir des articles. Ces substrats sont ondulés et l'articulation est faite de plusieurs feuilles amincies, horizontalement et perpendiculairement. Cette alternance d'orientation permet de réduire le déséquilibre entre les bords raccordés et les bords libres du substrat. L'invention concerne également un appareil permettant de former une gaine ayant des engrenages entrecroisés à dents biseautées faisant face aux surfaces des bords.
