Apparatus for cutting labels from a ribbon on which the labels are printed. The ribbon is fed into the apparatus along a vertical plane, for instance. There are vertically spaced apart knives adjacent the ribbon for cutting the upper and lower contours of the labels from the ribbon. The knives are caused to pivot toward the ribbon and to rise and fall under the influence of a cam that is shaped correspondingly with the desired contours. After the upper and lower contours are formed the ribbon is caused to change direction around a roller while at the same time the trim margin is deflected in another direction and drawn away. The ribbon, with labels still connected endwise is fed over a vacuum cylinder which has cutters at its periphery for separating the labels from a waste portion between them. The labels are removed from the vacuum cylinder and led to a label applying machine, as an example.
