Also, it is contemplated that the detector device, like for example, a photograph-mobile phone sensor, may be placed on the packaging materials dispenser of stretch wrapping machine to find the orientation in the film crack sensing roller . The detector device might be set up to deliver a signal into a control to give the apparatus 100 to a residence situation and prevent. It may well moreover signal an proprietor that we have seen a breakdown.

According to yet another aspect of the invention, the mechanical connection between the rotational drive system and the pre-stretch assembly may be replaced by an electrical connection. Such an embodiment, two individual pushes may be presented, a first rotational drive for delivering relative rotation involving the load and the packaging fabric dispenser, plus a 2nd rotational push for spinning the pre-stretch rollers of the pre-stretch construction. The two rotational drives may be electronically linked such that a ratio of the drive speeds remains constant throughout a primary portion of the wrap cycle in order to permit the pre-stretch assembly to dispense a predetermined substantially constant length of film for each revolution of the dispenser relative to the load. A way for providing relative rotation between the stress along with the dispenser may include any of the methods previously discussed, e.g., straight or horizontal stretch wrapper and wedding rings, rotatable biceps and triceps, and turntables.
