Abstract

L'invention concerne un appareil (10) destiné à souder les bords tenus ensemble de tissus, en utilisant de l'énergie thermique. Cet appareil comporte une pince (16) ayant des éléments (28, 30) qui serrent et maintiennent les tissus. Un matériau transmetteur (52) est supporté par au moins un des éléments. Les éléments (28, 30) pivotent pour amener les bords des tissus en contact étroit avec le matériau transmetteur (52) pour former une soudure. De l'énergie thermique est alors dirigée vers les tissus à travers le matériau transmetteur (52) et au niveau de la soudure avec une intensité et pendant une durée suffisantes pour chauffer les tissus jusqu'à les transformer en une substance protéinique adhésive permettant de sceller la couture. Les bords rapprochés sont maintenus contre le matériau transmetteur (52) avec une pression appropriée pour éviter un retournement excessif des bords vers l'extérieur ou vers l'intérieur.
