AI Technical Summary
Technical Problem
Existing wrapping technologies face challenges in achieving quick, effective, and secure attachment of pre-stretched film to loads, often resulting in inefficient use of material and safety risks due to manual intervention or inadequate mechanical guidance.
Method used
An apparatus and method utilizing a delivery head with pre-stretching rollers, a control roller, a drive unit, a source of compressed air, an electrostatic charger, and a deflector, controlled by a control unit to manage the film's orientation and attachment to the load through multiple operational configurations.
Benefits of technology
Ensures rapid and reliable film attachment to loads, optimizing wrapping operations by minimizing material waste and ensuring secure adhesion without manual intervention.

Abstract
Described is an apparatus (100) for wrapping with a pre-stretched film (200) a load (300) supported by a surface (310) comprising: a delivery head (1), provided with a delivery mechanism (2) for delivering the film (200); a drive unit, for generating a relative movement between the delivery head (1) and the load (300); a source of compressed air (3), for generating a flow of air in such a way that the flow of air blows the film (200) delivered; an electrostatic charger (4), for applying an electrostatic charge to the film (200); a deflector (5), movable between a first position, wherein the deflector orients the flow of air for blowing the film (200) delivered along a first vertical plane (P) which does not intersect the load (300), and a second position, wherein the deflector orients the flow of air for blowing the film (200) delivered along a second plane (Q), vertical and intersecting the load (300). A control unit controls the movement of the deflector (5) between the first position and the second position by means of an actuator (6).
