A foil reel mounting device (10; 40) for supporting a reel (2) of stamping foil (3) in a supporting module (1). The device is fixed to the supporting module (1). It includes a support (11; 41) having a recess (16; 46) to receive an axle (7) of the reel (2) of stamping foil (3). A retaining element (12; 42) mounted on the support (11; 41) and arranged to move between a closed position, in which the retaining element (12; 42) retains the axle (7) of the reel (2) in the recess (16; 46), and an open position, in which the retaining element (12; 42) releases the axle (7) of the reel (2) from the recess (16; 46). The retaining element (12; 42) is biased towards the closed position. Also, a supporting module (1) has at least one foil reel mounting device (10; 40) and a stamping machine (100) includes a supporting module (1) or at least one foil reel mounting device (10; 40). A method for loading and unloading a reel (2) of stamping foil (3) with such at least one foil reel mounting device (10; 40) is also disclosed.

According to one aspect of the present invention, when there is no leaf object striding over a boundary of two leaf rolls in a leaf image, a leaf image generating section performs processing for dividing first leaf image in first print data for leaves and a second leaf image of second print data for leaves at the boundary, replacing one of divided leaf images with one of other divided leaf images that hold the boundary between the first leaf image and the second leaf image to generate a first combined-leaves image and a second combined-leaves image, and rotating the second combined-leaves image at a predetermined angle.
