Abstract
Abstract A stacking device for a longitudinal member being transported along a predetermined path of movement is disclosed. Arresting means are disposed along the predetermined path of movement for arresting the longitudinal member adjacent to a preselected location. The stacking device has a stacked supporting means adjacent the preselected location on one side of the predetermined path of movement. A movable guide means is disposed on the one side of the predetermined path of movement and is operable to guide longitudinal member from the predetermined path of movement and are reciprocable between a rest position and a stacking position to move the longitudinal member from the predetermined path of movement over the guide means and onto the stack supporting means. Elevating means are connected to the movable guide means for moving the guide means, after delivery of the longitudinal member to the stack supporting means, so that the guide means is aligned with the top of the stacked longitudinal member preparatory for the transfer of another longitudinal member by the stacking device onto the stacked longitudinal member on the stack-supporting means.
