ABSTRACT:
Apparatus for assembling axially elongated, diametrically expandable and contractible product bags axially within energy sleeves of elastomeric material which are at least partially diametrically expanded at assembly. The apparatus comprises three, (3) energy sleeve expansion stations where at the elastomeric sleeve is sequentially expanded by the insertion of expansion rods and/or tubes therewithin. From the third station the energy sleeves proceed to an assembly station with an expansion tube therewithin. At the assembly station a product bag is inserted axially within the expansion tube in the energy sleeve with an end portion protruding from the tube. A first mechanism moves the energy sleeve axially relative to the tube so that an end portion surrounds and frictionally grips a part of the protruding product bag. A second assembly mechanism grips the protruding end portion of the bag and withdraws the bag from within the expansion tube with the energy sleeve following and sliding axially from its position about the expansion tube.
