摘要:
A wrapping machine for wrapping material around a load includes a wrapping unit to wrap a portion of the material around the load and a supplying unit to supply the material portion to the wrapping unit. The wrapping unit includes wrapping device to unwind the material portion from the supplying unit and wrap it around the load. The wrapping unit includes a supporting ring, rotating around a wrapping axis and provided with a plurality of wrapping rollers, and an unwinding arm having a first end rotatably fixed to the support ring and a second end supporting at least one unwinding roller to abut and guide the portion of material towards the load during wrapping. The unwinding arm is movable to move the unwinding roller to/from the load during wrapping.

A measuring device for detecting and measuring a wrapping force of a stretchable plastic material film wrapped around a load includes a first angular element that can be associated and fixed to at least one of an edge and a flat wall of the load, at least one force sensor fixed to the first angular element, a second angular element fixed to, and supported by, the force sensor, and a control unit connected to the force sensor and arranged for receiving therefrom a signal related to a wrapping force exerted by the film on the second angular element by the film that is wrapped around the load and around the measuring device. A system for detecting and measuring a wrapping force of a stretchable plastic material film wrapped around a load includes one or more measuring devices associated with, and fixed to, the load at edges and/or at flat walls of the load and an external receiving unit that is arranged for receiving signals which are transmitted by the measuring devices and related to a wrapping force exerted by the film wrapped around the load and around the measuring devices.
