Abstract: A gantry film wrapping system and method useable for wrapping film about an elongated load. The system includes an overhead frame with first and second lateral support members for supporting opposing end portions of a carriage, which is reciprocatably translatable back and forth along the first and second lateral support members. A film wrapping apparatus having a rotary arm is coupled to the carriage, and a film wrapping carriage is coupled to a dependent member extending from an end portion of the rotary arm. The rotary arm and film wrapping carriage are rotatable in approximately 180 degree rotational increments between and during back and forth translations of the carriage along the first and second lateral support members of the overhead frame, wherein the film wrapping carriage is orbital in a substantially oval orbit about an elongated load disposed below the overhead frame.

Abstract: An apparatus for placing corner protectors having elongate panels meeting at right angles onto vertical corners of pallet loads having vertical sides defining vertical corner comprises a magazine to hold a supply of the corner protectors and mechanisms for removing one corner protector from the magazine, transferring the corner protector to a position where one of its panels is disposed in close proximity to a vertical side of such a load, and displacing the corner protector until its other panel engages another side at the same corner of the load. In the magazine, the corner protectors extend vertically and are nested within one another. Also, the corner protectors are guided forwardly along a supporting chute. A wheeled carriage having an upright member is mounted operatively in the chute and prevents the corner protectors from tipping backwards.

Abstract: Apparatus for vertically regulating the dispensing height of stretchable wrapping material for stretch wrapping a load which comprises carriage means for varying the height of the carriage means between predetermined upper and lower positions, and safety means to prevent the fall of the carriage means to the lower position in the event of a failure of the height varying means. Also, a methods for preventing the accidental downward movement or falling of the carriage means in the event of a failure of the height regulating means which comprises providing safety means to grasp the frame means of a stretch wrapping apparatus when the height varying means breaks or fails.

Abstract: A system for measuring weight of objects using a single load cell means which comprises a pair of structural means having at least four sides and four corners, with pairs of opposed sides being substantially equal in length, a tensioned member positioned at each of said four corners of the structural means and load cell means extending therebetween an generally centrally thereof which is maintained under a predetermined compressive force applied by the structural means.
