  • Package transporting apparatus
    Patent number: 4601434
    Abstract: An apparatus for transporting a package doffed by a spinning frame to a winder. Packages are independently transported on a package supply conveyor by means of a peg tray which includes a guide member for securing thereto an end of a yarn extracted from the package. The package carrying tray is delivered to a frictionless inclined pathway and proceeds under its own weight to a winding position adjacent a winding unit.
