The invention is directed to method and apparatus for making pads, such as interlabial pads. The apparatus includes a blending apparatus that weighs and blends fibers of different materials, at least one of which is absorbent. The blended fibers are conveyed through a chute to a fiber collection station. At the fiber collection station, collecting and feeding apparatus collects the blended fibers and feeds them to a forming apparatus that forms the blended fibers into a continuous blended-fiber web. The blended-fiber web is fed to a pad-making apparatus that cuts fluid-absorbent bodies in the blended-fiber web and laminates the bodies with at least one continuous cover web to form a laminated web. The laminated web is fed to a sealing and cutting apparatus to make the pads. Folding apparatus is provided for folding each pad along a major axis thereof.

L'invention concerne un procédé et un appareil de fabrication de serviettes, telles que des serviettes interlabiales. Ledit appareil comprend un appareil de mélange qui pèse et mélange des fibres de différentes matières, au moins une de ces matières étant absorbante. Les fibres mélangées sont transportées à travers une goulotte jusqu'à une station de collecte des fibres, dans laquelle un appareil de collecte et d'alimentation collecte les fibres mélangées et les achemine jusqu'à un appareil de façonnage qui les façonne sous la forme d'une bande continue de fibres mélangées. Cette bande de fibres mélangées est ensuite acheminée dans un appareil de fabrication de serviettes qui découpe dans ladite bande des corps absorbant les fluides et recouvre ces corps d'au moins une bande continue de recouvrement de façon à former une bande stratifiée. Cette bande stratifiée est transportée jusqu'à un appareil de scellage et de découpage dans lequel les serviettes sont fabriquées. Un appareil de pliage plie ensuite chaque serviette le long de son grand axe.
