Abstract
Abstract A mechanism is described for removing a filled cloth roll from a loom and for transporting a plurality of said removed said filled cloth rolls away from the loom area. A doffing cart is provided which is adapted to be placed adjacent the horizontally extending filled cloth roll on the loom and includes means for lifting the roll, when detached, horizontally onto the cart. The doffing cart with the filled cloth roll secured thereto may then be lifted to an upright position, where the filled cloth roll extends vertically, and the doffing cart may then be rolled away from the loom in the narrow aisles generally provided between looms. A receiving cart is provided which is adapted to receive the filled cloth roll from the doffing cart, store a plurality of said rolls and transport said plurality of rolls away from the loom area. Further, the receiving cart may store a number of empty rolls for installation in the looms when the filled rolls are removed therefrom. The doffing cart includes a tongue means adapted to be engaged with a coupling bar on the receiving cart placing the platform which supports the vertical filled cloth roll on the doffing cart substantially flush with the floor of the receiving cart so that the filled cloth roll need only be slid from one cart to the other.
