Abstract
The apparatus for receiving and forwarding a reserve lap roll employs a trough to receive the lap roll and pivotally mounted arms for pivoting the trough from the reserve position toward the working position. The arms may be pivoted by a piston and cylinder unit. Alternatively, a parallelogram arrangement of guide rods may be used for moving the trough from the reserve position toward the working position. In still another embodiment, pairs of pivotally mounted arms can be used to move the reserve lap roll from the reserve position directly into the working position. In each embodiment, the pivotal elements are spaced apart a distance greater than the length of an empty tube in the working position so that the empty tube can be ejected through the space between the arms to a position below the reserve position.
