Abstract: An unwind station for a packaging machine may be configured to form wrappers having different sizes from a web of packaging material and supply the wrapper to a wrapping station. The unwind station may include a base configured to support the web of packaging material and a carriage configured to selectively slide in a longitudinal direction on the base. A rotating blade can be configured to periodically score the web to form a break line extending between lateral sides of the web. A first conveyor arm and a second conveyor arm may project longitudinally outward from the carriage. The first conveyor arm and the second conveyor arm can each include a low-speed conveyor configured to transport the web to a high-speed conveyor. The high-speed conveyor is configured to separate the wrapper from the web as the break line passes a shear point between the low-speed conveyors and the high-speed conveyors.

Abstract: A rotating tucking device for securing a wrapper to a roll in a roll packaging system comprises a tucking arm for insertion into a hollow cavity of a roll and a rotating insertion system connected to the tucking arm for moving the tucking arm in a rotational pattern coordinated with the movement of the roll through the roll packaging system such that the tucking arm and the rotating insertion system tuck a wrapper into the hollow cavity of the roll as the roll moves continuously through the roll packaging system. Also provided is a roll packaging system having a rotating tucking device, as well as a rotating tucking method for securing a wrapper to a roll as the roll moves continuously through the roll packaging system.

Abstract: The device (1) is associated, in line, to an outlet of a packing machine and is designed to seal superposed flaps (Ls, Li) of packs (C), at longitudinal vertical sides (V) thereof. The device includes apparatus (2) for receiving and moving the packs (C) and includes two batteries (3, 4) of heat-welding rollers (30, 40), having a vertical axis, for acting on respective longitudinal vertical sides (V) in order to heat the flaps (Ls, Li) up to a temperature which is sufficient to cause joining by aggregation of the packing material. Cooling is provided downstream of the batteries (3, 4) for acting on the flaps (Ls, Li) in order to lower the temperature thereof and thus stabilize the joint.

Abstract: A modular packaging system includes a base system configured to manipulate a product and configured to receive at least one of a group of packaging modules, wherein the base system is used with a variety of packaging modules depending on a desired packaged output. The system also includes a first packaging module selectively coupled to the base system, the packaging module having a first member coupled to the packaging module, the member configured to manipulate an object. The system may also include a second packaging module selectively coupled to the base system, the second packaging module having a lifting device coupled to the second packaging module, the lifting device configured to manipulate an object.
