Abstract

See full text

The invention concerns a device for unrolling a strip (10) for a stamping machine (1) that allows an accumulation of the strip to be stamped (2) under a pre-unrolled form between at least one stamping spool (3) and a plate press (310) of the stamping machine (1), so characterized in that the device for unrolling a strip (10) comprises:

    a central drum (11) configured to be led in rotation at a variable advance speed, united in rotation with an axis of the device for unrolling the strip (10),a satellite roller (14) presenting an axis (11) constructed parallel to the axis of the central drum (11), where the satellite roller (14) can be turned around the central drum (11), and the pre-unrolled strip may be rolled around the central drum (11) due to the movement of the satellite roller (14), anda planetary leading device (15) to move the satellite roller (14) around the central drum (11) as a function of the difference of the rotation speeds of the central drum (11) and of an exterior ring (13) of the planetary leading device (15) configured to be led in rotation at a constant speed in the rotation direction contrary to the rotation direction of the central drum (11).
