Abstract: A modular comb element for a machine for automatically cutting a mat of sheets of material. The cutting machine includes a plurality of cutting supports. The comb element includes a plate forming a support from which a first and a second row of teeth extend longitudinally. The teeth of the first row alternate with the teeth of the second row, and a free end of the teeth of the first row are farther from a downstream edge of the support than a free end of the teeth of the second row of teeth. A ramp is mounted on the downstream edge of the support and inclined with respect to the latter so as to limit the contact surface between the mat of sheets and the comb element. Air injection means are at a downstream edge of the ramp over an entire width thereof.

Abstract: The present invention relates to an assembly for a turbomachine turbine extending along an axis (X), comprising: —an ejection cone (100) comprising a radially outer annular wall (102) defining a flow duct for a flow of hot gases and a sound box radially arranged inside the outer annular wall (102), the sound box comprising a radially inner annular wall (104), —a connecting member (106) intended to be axially inserted between the exhaust housing and the ejection cone (100), the connecting member (106) comprising an upstream annular flange (108) intended to be attached to the exhaust housing and a plurality of downstream securing tabs (110) connected to the inner annular wall (104), —an annular sealing shroud (112) comprising an upstream portion surrounding the securing tabs (110) of the connecting member (106) so as to cover the spaces circumferentially located between the securing tabs (110) and axially located between the upstream annular flange (108) of the connecting member (106) and the radially inner ann

Abstract: A modular cutting-support element with suction in a machine for automatic cutting of sheet material by means of blades, includes a plurality of bristles arranged in the same single line, at least some of the bristles each having a base rigidly connected to a bearing plate intended to be mounted on a support, a head opposite the base on which a sheet material to be cut is intended to rest, and a stem connecting the head to the base, the largest cross-section of which is strictly included in the largest cross-section of the head, the bearing plate comprising, on each of its side surfaces, a plurality of transverse channels for the passage of suction air providing communication between an upper surface of the bearing plate from which the bristles extend and an inner surface opposite the upper surface.
