Abstract

See full text

A method for wrapping a load with a film by a wrapping machine including an unwinding apparatus provided with a reel of the film includes moving the wrapping apparatus and the load in relation to one another and unwinding from the reel an established effective length of film per revolution of the wrapping apparatus or of the load. The established effective length of film is calculated with the formula: where: Sf. initial length of film is determined on the basis of dimension and/or shape of the load; ω: rotation speed around a wrapping axis of the unwinding apparatus or of the load; Vt: movement speed of the unwinding apparatus parallel to the rotation axis; ωmax: maximum rotation speed around the wrapping axis of the unwinding apparatus or of the load; Δcorr: corrective parameter.
