Abstract: The bristle brush comprises a support plate (1), a plurality of flexible bristles (2) emerging from one of the surfaces thereof, the ends of the bristles (2) furthest from the support plate (1) defining a support surface intended to receive a part to be transported and/or cut, wherein said support plate (1) comprises a leading edge (11) and a trailing edge (12), said leading (11) and trailing (12) edges comprising complementary shapes. It enables a conveyor belt formed by said brushes to achieve very small turning radii.

Abstract: The sharpening system for cutter blades for cutting flexible materials in automatic cutting machines comprises at least one sharpening element, and it also comprises a first sharpening module that includes at least one first sharpening element, and a second sharpening module that includes at least one second sharpening element. It provides a sharpening system that offers an integral and simple solution to current sharpening systems by incorporating an active sharpening system in the guide plate, either in the rotary area or on the outside, or symmetrically in the upper part of the lower body of the cutting head, interchangeably.
