Device and method for feeding a web of a packaging material

摘要

A device for feeding a web of a packaging material along a path and towards an application station; wherein the packaging material comprises a plurality of pre-laminated holes at which application station applies respective opening devices. The device comprises an advancing mechanism for advancing the web along a first direction parallel to path; a sensor for generating a plurality of measure signals associated to the positions of pre-laminated holes; and a first motor controllable on the basis of measure signals. The first motor is operatively connected to the advancing mechanism for moving the advancing mechanism along a second direction transversal to path.
