Patent ID: 7357169

Claim:
An automatic machine for applying a flexible tape on a substantially flat glass pane, comprising: a machine body comprising a substantially vertical plane of arrangement, a first, horizontal movement axis and a second, substantially vertical movement axis, said first and second movement axes being perpendicular to each other and parallel to said plane of arrangement; movement means provided on said machine body for moving along said first movement axis at least one flat glass pane that is arranged on said plane of arrangement; a carriage that is movable along guiding means provided on said machine body parallel to said second, substantially vertical axis; an application head for applying a flexible tape along a perimetric edge of said glass pane and which is rigidly coupled to said carriage for rotation about a third axis and for translational motion along a fourth axis, said third and fourth axes being substantially perpendicular to said plane of arrangement; feeder means, rigidly coupled to said application head, for feeding said tape along an advancement direction thereof; supporting means which are rigidly coupled to said carriage for supporting at least one storage spool for said tape, said supporting means supporting said storage spool so as to be rotatable about a longitudinal axis thereof, said supporting means and said application head being jointly movable with said carriage in its motion along said second movement axis, while said supporting means are coupled to said carriage so as to be independent of said application head both as regards rotary motion of the application head about said third axis and translational motion thereof along said fourth axis; first actuation means for actuating said movement means to move the glass pane with a translational motion alone said first movement axis; second actuation means for actuating said carriage with a translational motion along said second movement axis; third actuation means for actuating said application head to rotate about said third axis; fourth actuation means for actuating said tape feeder means, which are concatenated and controlled by a controller for synchronization and coordination of relative movements of said head and of said glass pane and of a motion for the feeding of said tape in order to apply the tape along the perimetric edge of said glass pane; and wherein said feeder means comprise two continuous belt conveyors, which are arranged one above the other along a longitudinal extension of said tape, are suitable to make contact with opposite faces the tape, and are associated with said head at an adjustable distance from each other, said fourth actuation means comprising motor means which are associated with said belt conveyors and are provided with corresponding transmission means interposed between the motor means and said belt conveyors.
