CA 2459573

An attachment gusset with ruffled corners and method and machinery for manufacture provides a gusset formed of a continuous strip of material which is pleated at corners or turns in direction of the gusset to form ruffles which are attached to an adjacent layer of material. The ruffled gusset lies substantially flat against adjacent layers of material to which it is attached in a pressed state, and can be expanded to accommodate dimensional structures, such as cushioned pads. The number and spacing of pleats can be adjusted according to the radius of the corners or turns in the gusset. In a method of construction of the gusset, the pleats are formed as the material to which the gusset is attached is turned relative to the sewing point of attachment.

L'invention concerne un soufflet de fixation à coins à volant, un procédé et une machine permettant de fabriquer un soufflet formé d'une bande continue de matériau plissé au niveau des coins ou des angles dans le sens dudit soufflet afin de former des volants froncés fixés à une couche adjacente de matériau. Le soufflet à volant froncé s'étend sensiblement à plat contre des couches adjacentes de matériau auxquelles il est fixé à l'état aplati, et peut être détendu de façon à s'adapter à des structures dimensionnelles, telles que des garnitures de rembourrage. Le nombre de plis et les espaces entre eux peuvent être réglés en fonction du rayon des coins ou des angles dans le soufflet. Dans un procédé de fabrication du gousset, les plis sont formés à mesure qu'on fait tourner le matériau auquel ledit gousset est fixé par rapport au point de couture de fixation.
