Abstract:
1. A labeling machine, comprising a conveyor of containers, each to be labeled with a label taken by cutting from continuous ribbon wound in a reel, an intermittent cutting device for intermittent cutting of each individual label, a feeder which is adapted to convey with the appropriate timing the ribbon in a feeding direction to said intermittent cutting device, said feeder comprising a device for unwinding the ribbon from a reel and a pair of rollers for moving the ribbon which are arranged in the immediate vicinity of said cutting device, a drum for transferring the cut label to a container provided on the conveyor, and a label locking mechanism for locking the label during cutting, said label locking mechanism being arranged downstream of said cutting device with respect to said feeding direction of the ribbon and said label locking mechanism being arranged between said cutting device and said drum for transferring the cut label with respect to said feeding direction of the ribbon, said label locking mechanism comprising a slider and a fixed block provided with an fixed abutment surface, said slider and said fixed block being arranged at opposite sides of said ribbon, said slider being configured to move between a cutting position for compressing said label in contact with said abutment surface whereby the label is cut when said slider compresses said label in contact with said abutment surface in said cutting position and a position for separation from said label, said ribbon moving between said pair of rollers which are arranged adjacent said cutting device, said cutting device being arranged between said pair of rollers and said label locking mechanism with respect to said feeding direction of the ribbon; wherein said pair of rollers are configured to exert a compression force on the ribbon such that a tension is maintained in the ribbon between the pair of rollers and the label locking mechanism when the label locking mechanism is in the cutting position.
