Thorough DESCRIPTION OF THE PREFERRED EMBODIMENTS

A process and apparatus for stretch wrapping a roll item is proven in FIGS. 1-8. The device features a body 50, a stretch wrap machine and dispenser 52, a clamp construction 54, rollers 58 and 56, and a control system 60.

The stretch wrap dispenser and machine 52 might be a standard stretch wrap dispenser and machine. Appropriate dispensers and machine are displayed in United states Pat. No. 5,161,349, which happens to be included herein by reference. As demonstrated in FIG. 9, stretch wrap machine and dispenser 52 could include a support 62 for the roll 64 of stretch wrap wrapping material such as a film website 66. dispenser and Machine 52 also may add a prestretch device 68 developing a downstream curler 68b that is tailored for an upstream roller 68a to swivel quicker than upstream roller 68a. One more roller 70 may possibly help in dispensing film internet 66. As proven in FIG. dispenser, machine and 11 52 is mounted along with beam 51 of body 50 to be controllably pushed together ray 51 by an electric electric motor travel using a holder and pinion engagement with beam 51.

As demonstrated in FIG. 12, clamp set up 54 ideally contains a rotatable mounting such as a number band through an external race 72, that is mounted on body 50, and an inside competition 73, which is installed for rotation about horizontal axis 74. Electric motor 75 drives internal competition 73 by way of a mechanical push say for example a reducer, coupling, 90?? products package and sequence and sprocket generate. Other push and installing plans also can be utilized as alternatives. It is additionally possible to additionally push the inside race 73 by way of a immediate or indirect proposal with yet another travel device, including the top of the fill.

As proven in FIGS. 12 and 11, a traverse arm 76 is mounted on the works with 73a which increase axially from internal competition 73 and swivel with inner competition 73 about axis 74. Counterweight 85 is attached to internal race 73 to countertop equilibrium traverse arm 76. Carriage 78 rides together songs 79 on traverse arm 76 and is also linearly translatable from a single finish 76a towards the other end 76b of traverse left arm 76 with a driving a vehicle device for instance a rodless atmosphere air and cylinder braking system 77 that is attached to traverse left arm 76. A clamp 80 is installed on carriage 78.
