Abstract
In apparatus for applying a sliver at a bias to an endless backing web in the making of a paper machine felt, a needle machine is preceded by a sliver feeder, which is operable by a traversing drive to perform a traversing movement across the working width of the needle machine. Irregularities can be avoided because an automatically controlled position-correcting mechanism is provided, which serves to compensate any deviation of the actual course of one longitudinal edge of the backing web from a predetermined, desired course of said longitudinal edge, and means are provided for controlling the traversing drive so that the traversing movement of the sliver feeder will be influenced by changes of the width and/or length of the backing web.
