  • Laminated clothing, as well as method and blank for manufacturing the same
    Patent number: 6265048
    Abstract: The invention relates to a laminated clothing for a papermaking or cellulose manufacturing machine, as well as a method and a blank for manufacturing thereof. The clothing comprises two laminated layers (O, I), each having an inclined direction-defined thread system, the thread systems being inclined relative to the machine direction of the clothing and relative to each other. The two layers (O, I) constitute an upper and an inner part, respectively, of an endless band (40), which is so flattened that two edge folds (48, 50) are formed transversely of the machine direction, and which is then doubled with the edge folds (48, 50) coupled together. As a result, the band comprises a direction-defined thread system which is inclined relative to the machine direction and which, owing to the flattening and doubling of the band, forms the thread systems, inclined relative to each other, of the first and the second layer (O, I).
