Abstract
A device for adjusting the size of the gap between an adhesive scraper of a labelling machine and an adhesive roller of the labelling machine. The device includes at least two independently controllable actuators that adjust the gap to different sizes from one another. The actuators may take the form of hydraulically or pneumatically controlled pistons and cylinders.
Claims20
A labelling machine comprising:
- a labelling station;
- means for supplying labels to said labelling station;
- mean for supplying objects to be labelled to said labelling station;
- said labelling station having an adhesive application roller;
- means for supplying adhesive to said adhesive application roller;
- and
- means for variably adjusting a thickness of adhesive on said adhesive application roller;
- said means for variably adjusting a thickness of adhesive on said adhesive application roller comprising:
- blade means for adjusting the thickness of adhesive on the adhesive application roller;
- said blade means comprising a thickness forming edge disposed in an adjacent but noncontacting disposition with respect to said adhesive application roller;
- automatically actuated positioning means for moving said thickness forming edge of said blade means between a plurality of discrete noncontacting positions adjacent the adhesive application roller;
- control means for positioning said thickness forming edge of said blade means at a selected one of said plurality of discrete noncontacting positions adjacent said adhesive application roller;
- said thickness forming edge of said blade means and said adhesive application roller to define a gap therebetween at each said position of said blade means;
- said blade means being configured to form a thickness of adhesive on the adhesive application roller corresponding to each said gap;
- and
- each thickness of adhesive corresponding to each said gap being different from each other thickness of adhesive corresponding to each other said gap.

Apparatus for variably adjusting a thickness of adhesive on an adhesive application roller of a labelling machine, said apparatus comprising:
- blade means for adjusting the thickness of an adhesive on the adhesive application roller;
- positioning means for moving said blade means between at least three rigidly maintained, discrete and reproducable positions adjacent the adhesive application roller;
- said blade means and the adhesive application roller to define a gap therebetween at each said position of said blade means;
- said blade means being configured to form a thickness of adhesive on the adhesive application roller corresponding to each said gap;
- and
- each thickness of adhesive corresponding to each said gap being different from each other thickness of adhesive corresponding to each other said gap.

Apparatus for variably adjusting the thickness of adhesive on an adhesive application roller of a labelling machine, said machine comprising:
- means for adjusting the thickness of adhesive on the adhesive application roller;
- means for automatically and selectively controlling said means for adjusting the thickness of adhesive on the adhesive application roller to at least three rigidly maintained, discrete and reproducable positions adjacent the adhesive application roller;
- said means for adjusting the thickness of adhesive on the adhesive application roller and the adhesive application roller defining a gap therebetween at each of said at least three rigidly maintained discrete and reproducable positions of said means for controlling the thickness of adhesive on the adhesive application roller;
- said means for adjusting the thickness of adhesive on the adhesive application roller being configured to form a thickness of adhesive on the adhesive application roller corresponding to each said gap;
- and
- each thickness of adhesive corresponding to each said gap being different from each other thickness of adhesive corresponding to each other said gap.
