Abstract
A suction cutting conveyor of an automatic blade cutting machine for sheet materials, including a plurality of cutting supports rigidly connected to a drive mechanism driven along rectilinear and curvilinear trajectories, each cutting support including a plurality of bristles each having a foot rigidly connected to a sole and a head opposite to the foot and on which a sheet material to be cut is intended to rest, the sole of each cutting support being capable of being able to elastically deform following the trajectories of the drive mechanism.
Claims13
A suction cutting conveyor of an automatic blade cutting machine for sheet material, the conveyor comprising:
- a plurality of cutting supports rigidly connected to a drive mechanism driven along rectilinear and curvilinear trajectories, each cutting support comprising a plurality of bristles each having a foot rigidly connected to a sole and a head opposite to the foot and on which a sheet material to be cut is intended to rest,
- wherein the conveyor is housed in a box having a vacuum configured to hold immobile the material sheet during cutting operations,
- wherein the sole of each cutting support elastically deforms by a reversible deformation without creep following the trajectories of the drive mechanism and wherein transverse channels are provided through the soles of the cutting supports in order to allow suctioned air to pass through the soles,
- wherein the sole is arranged to return to an original shape following the reversible deformation, and
- wherein the sole comprises a plurality of parallel slots including external slots protruding outward with respect to an outer surface of the sole and internal slots protruding inward with respect to an inner surface of the sole.
