Labeling device in a labeling machine with continuous introduction of a film containing labels in reel form

A labeling device in a labeling machine with the continuous introduction of a film containing labels in reel form, comprising:

• a cutting group having a blade located along a generatrix of a rotating roller and a counterblade,
• a gripping and transfer drum for gripping and transferring a label cut by said blade towards a device for applying glue in predetermined zones and subsequently onto a container, and
• a resilient support having a fork-shaped cross-section with two arms joined together in a portion which forms the point of rotation of the arm carrying said counterblade, and a wedge actuated by an adjusting screw to press against and cause rotation of the arm carrying said counterblade, said support for positioning said counterblade with respect to the point of tangency between the gripping and transfer drum and circumference described by said blade at a distance such that at least two thirds of the label are retained by said gripping and transfer drum at the moment of cutting of the label from the film by said blade.
