Patent

CA 2637793

Many types of stabilized lock-seam tubing are provided, as well as devices, apparatus and methods for producing such stabilized tubing. Advantageously, pinch-locked tubing according to the invention, which comprise interlocking, spaced pinched deformations of the lock-seam, greatly resists side-slip and other shape deformations, including those typically produced by cutting the tubing, and by ovalizing it. Many permutations of lock-seam pinching rollers and related devices for producing stabilized lock-seam tubing are provided. Pinch roller assemblies of the invention are suitable for use with conventional machines as well as machines adapted specifically for them. Apparatus of the invention are suitable producing helically wound or straight lock-seam tubing.

La présente invention concerne de nombreux types de tubes agrafés stabilisés ainsi que des dispositifs, des appareils et des procédés permettant de fabriquer de tels tubes stabilisés. Selon la présente invention, le tube agrafé présente l'avantage de comprendre au niveau de l'agrafage des déformations rétreintes espacées à emboîtement et de résister fortement au dérapage et à d'autres déformations dont celles obtenues généralement en coupant le tube et en le rendant ovale. L'invention porte aussi sur de nombreuses permutations des rouleaux pinceurs agrafés et des dispositifs associés en vue de produire des tubes agrafés stabilisés. Les ensembles rouleaux pinceurs de l'invention peuvent s'utiliser avec des machines classiques ainsi qu'avec des machines conçues spécialement pour eux. Les appareils de l'invention conviennent à la production de tubes agrafés droits ou à enroulement hélicoïdale.
