<p>The cutting cylinder (2) of a rotary cutting machine comprises at least one radial needle (8) for retaining waste (10) and projecting radially from its surface. A waste ejector (11) has a rectilinear part (11b) parallel to the generatrix of the said cylinder (2) and traversed by at least one slot (11a) coinciding with the trajectory of said radial needle (8) for the passage thereof. A support (12) has a first part (12a) secured to the frame of the rotary cutting machine, a second part (12b) secured to said ejector (11) and connected to the first part (12a) by guide means (12c) defining a transverse trajectory. relative to the edge (11b) of said ejector (11) and intersecting said cylinder (2). Adjustment means (17, 18, 21) serve to move the said second part (12b) along the said transverse trajectory and elastic means (12c) for exerting a prestressing of the said second part (12b) on the said adjustment means (17, 18, 21).</p> |
