摘要:
Un dispositif d'extension en largeur (100) comporte deux cylindres (1, 2, 3) présentant des reliefs complémentaires (15), par exemple des reliefs hélicoïdaux, qui s'engrènent lorsque les cylindres (1, 2, 3) tournent. La bande de matière (10) est guidée à travers la fente d'extension (12, 13) constituée entre les rouleaux (1, 2 resp. 1, 3) et subit une extension selon la profondeur d'engrènement des reliefs (15) entre deux proéminences adjacentes dans le sens de la largeur de la bande de matière (10). L'extension en largeur locale spécifique est ainsi produite uniformément sur toute la largeur de la bande de matière. L'élément essentiel pour la production de cet effet est un cylindre de pression (7) qui serre la bande de matière (10) entre lui et les sommets du relief (15) et la maintient dans le sens de la largeur.
摘要:
The small finishing installation (100) for continuous strips of textile fabric includes a steam-filled housing (2) into which feed rolls (5) can be introduced at each end. Located in the housing are sets of fabric-handling equipment disposed symmetrically with respect to the vertical plane (40) running across the middle of the housing (2). Disposed in this vertical plane (40) is a squeezer unit (37) from which the strip of fabric can pass, against each feed roll (5), through a treatment bath (30) and then over an array (20) of guide rollers disposed above an open tank (26). The continuous strip of fabric (10) can be wound back and forth between the feed rolls (5), thus making it possible to carry out a variety of different treatments.
摘要:
Un dispositif de traitement en continu de bandes textiles comprend un ou plusieurs applicateurs d'un ou plusieurs bains de traitement sur la bande textile (10). Après cette application, la bande textile (10) a une humidité totale considérable, dans une plage comprise entre 100 % et 220 % du poids de la bande sèche. La bande textile (10) pénètre ainsi chargée dans une zone verticale de chauffage (26) d'un vaporisateur (30), dans lequel elle suit un chemin qui forme une pluralité de lacets horizontaux.

摘要:
A width expanding device (100) comprises two rollers (1, 2, 3,) having complementary contours (15), e.g. helical contours, which mutually engage when the rollers (1, 2, 3) rotate. The product web (10) is taken through the expansion slot (12, 13) formed between the rollers (1, 2 or 1, 3) and is expanded in accordance with the depth of engagement of the contours (15) between two adjacent rises in the contours (5) across the width of the product web (10). The specific local width expansion is thus uniformly achieved over the entire width of the product web. The essential feature for the occurence of the effect is a pressure roller (7) adjacent to the expansion slots (12, 13) and bearing on the rollers (2, 3) which clamps the product web (10) between itself and the peaks of the reliefs (15) and secures it across its width.
摘要:
The device proposed for the continuous treatment of a textile fabric web comprises one or more applicators, by means of which one or more treatment liquors are applied to the web (10). The web subsequently has an elevated total moisture content in the range of 100-220 % of the dry weight of the fabric. The web (10) passes, with the absorbed liquors, into a tower-like structure containing the heating zone (26) of a steamer box (30), in which the fabric follows a multiplicity of horizontal loops.
