Abstract: A clip feed or advance mechanism for advancing clips on a guide rail into the window of a clip attachment apparatus includes an arm which supports biased jaw members into engagement with the clips. The arm is reciprocally driven by a piston and cylinder arrangement.

Abstract: An apparatus for packing fowl which includes first and second work stations. The first work station is provided to receive the product to be packaged. A pusher mechanism pushes the product from the first station between spaced plates into a plastic bag and then through the gates of a clipper mechanism. Advancement is slightly retarded by means of a blocking mechanism to thereby insure that the product is tightly retained within the flexible plastic bag. The bag and product are thereby moved to the second station at which time a holding bar preliminary closes the bag. Thence, gates close and gather the neck of the bag and a metal clip is advanced by means of a punch in a clip channel defined by the closed gates. The clip is thereby fastened about the neck of the closed plastic bag and the excess tail of the bag is cut by means of a knife. Trap doors then release the packaged product onto a conveyor belt, a new bag is positioned on the spaced, guide plates, and the apparatus is ready to recycle.

Abstract: Apparatus for adjusting the spacing of drive assemblies for transport of tubular film over a forming tube includes adjustment arms attached to each of the separate spaced drive assemblies which are attached to a rotatable adjustment plate. Rotation of the adjustment plate about its axis simultaneously moves the drive assemblies in equal and opposite directions with respect to the centerline of the tubular film product.
