Abstract
Abstract An aerosol container filling line for use with light-weight aluminum aerosol containers. The line includes an intermittently and linearly movable conveyor having pairs of upstanding pins located thereon for engaging a lower portion of the container and moving it along the line to and past various operating stations. A pair of longitudinally extending brushes are mounted to the production line on both sides of the conveyor and are adapted and arranged to engage the sides of the container at a position between the conveyor surface and the top of the pins so as to prevent the container from toppling rearwardly as the line begins to move from its stopped position.
