Abstract
A device to limit the glue width on a glue applying roll of a gluing station for applying glue on a sheet of material characterized by the glue applying roll dipping into a container of glue, a doctor blade engaging a surface of the glue applying roll to remove glue, said doctor blade being mounted by an arrangement which moves the blade laterally along the axis of the roll in response to the detected position of the web so that as the web shifts laterally, the edges of the glue film are simultaneously shifted. Preferably, the apparatus includes a second blade which is larger than each doctor blade which has an edge positioned spaced from the surface of the glue applying roll to reduce the size of the film in the area of the doctor blade.
