  • Patent number: 4495751
    Abstract: An apparatus and process for forming and dispensing individual wrappers of varying lengths from a supply roll of flat-folded tubular film is provided. The apparatus includes a rotatable turret which defines a plurality of appertures and has a plurality of hollow mandrels secured thereto in such manner that the interior of each hollow mandrel is communicatively connected to a respective apperture. In operation, a mandrel and tubular film loaded on the external periphery thereof is rotatively indexed from a stock receiving station to a stock dispensing station where the tubing is sealed, loaded with a product and severed to form an individual wrapper. A guide bullet is provided at the stock receiving station to assist in the loading of the tubular film onto the external periphery of a hollow mandrel upon the mandrel being indexed to the stock receiving station. In a preferred embodiment the guide bullet may be retracted through the interior of a mandrel by way of a reciprocal thrust rod.
