SPIKE-MOUNTING STACKED-BAGS PROCESS AND APPARATUS

The bag-mounting process and apparatus of the invention are directed to a spearing of stacked paper bags onto a needle-like spike rammed through stacked lips thereof with the spike piercing the lips from the lips' outer faces thereof near the lips' upper peripheries after first compressing the stacked lips in the stacked state, employing solely a linear spike having a concentrically tapered point at its piercing end and a blunt opposite end against which a plunger is pressed to ram the spike from a spike-supporting barrel aligned perpendicularly to the point for piercing, and mounting tabs or other retaining members on the opposite ends of the spike for retaining the pierced-bags on the spike against bags' tendency to slip-off during handling and shipping. Preferably the machine is pneumatically actuated and semi-automatic for at least part of the process, and is adjustable to receive bag-stacks of different widths of the bags thereof.
