A device for accurately positioning and orienting a kinescope at a preselected position includes a horizontally moveable but vertically fixed carriage which transports the envelope from a first loading position to a preselected position. A second carriage, which is vertically moveable and horizontally fixed, is centered at the preselected position. The second carriage normally is beneath the horizontally moveable carriage and is raised to lift the envelope from the horizontally moveable carriage. Neck centering members are coupled to the vertically moveable carriage and are boomerang shaped to include oppositely facing internally curved surfaces. The curved surfaces urge the neck of the envelope toward the preselected position irrespective of the tilt of the neck and assure that the neck is centered at the preselected position and that the longitudinal axis of the envelope is parallel to the vertical axis. Simultaneously rotatable bumpers are rotated to engage the sides of the envelope to assure that the horizontal and vertical axes of the envelope are parallel to the transverse and longitudinal axis of the device.
