Abstract (en)
[origin: US4614969A] A method and apparatus for producing an endless tubular felt includes superposing layers of tubular felt one upon the other and binding of the superposed layers together. A marking line is applied to the top surface of the superposed layers in continuous manner as the felt is trained about the driven rolls. The rolls include needle segments which move the felt axially of the roll. A scanner scans the position of the marking line shortly before the completion of one revolution. A controller compares the position of the marking line with a reference and causes the needle means to be adjusted to that the marking line corresponds with the reference.
