Suction channel end part, production method and drafting system comprising such a suction channel end part

A method for producing a suction channel end part for removing fiber flight in the region of a drafting system by applying negative pressure, the suction channel end part comprising a first component, to which negative pressure is applied and which has an inlet and an outlet communicating with the inlet, the method comprising:

• producing at least one part of the suction channel end part using a 3D printing method, a laser sintering method or a plastics injection-molding method,
• wherein the suction channel end part has a second component, which is a cover element and to which negative pressure is applied and which is exchangeably connected to the first component, the second component having an opening, which, in the joined state of the suction channel end part, forms a suction port, which communicates with the inlet and via which the fiber flight is removed into the suction channel end part when a negative pressure is applied.

A drafting system comprising a plurality of a roller pairs for the defined drafting of a fed fiber band,

• characterised in that
• a suction channel end part is arranged in the region of the drafting system, wherein the suction channel end part for removing fiber flight in the region of a drafting system by applying negative pressure, the suction channel end part comprising a first component, to which negative pressure is applied and which has an inlet and an outlet communicating with the inlet, wherein the suction channel end part has a second component, which is a cover element and to which negative pressure is applied and which is exchangeably connected to the first component, the second component having an opening, which, in the joined state of the suction channel end part, forms a suction port, which communicates with the inlet and via which the fiber flight is removed into the suction channel end part when a negative pressure is applied.
