A yarn-producing apparatus for an air spinning machine, which is used for producing a yarn from a fiber strand with the assistance of an air flow, has a spinning tip with an inlet opening surrounded by the outer surface of the spinning tip, in the area of which a yarn is able to be produced with the assistance of the air flow. The yarn-producing apparatus has an internal inset with a draw-off conduit adjacent to the inlet opening for the yarn and several air outlets branching off on the side from the draw-off conduit, such that an air flow introduced counter to the direction of spinning (S) in the draw-off conduit can escape in part through the air outlets and in part through the inlet opening. In addition, a spinning unit with a corresponding yarn-producing apparatus is provided.

System and method for determining a ripping path

A system for determining a ripping path includes a position sensing system, a work implement, and a controller. The controller is configured to determine a plurality of positions of the machine as the machine moves along an operating path and the work implement moves a volume of material and sense the material characteristics of at each of the plurality of positions along the operating path. The controller is further configured to determine the ripping path based upon the material characteristics sensed at the plurality of positions and store the ripping path.
