Abstract

DISPOSITIVO EM UMA MÁQUINA DE CARDAR ALGODÃO, FIBRAS SINTÉTICAS, E SIMILARES, DISPOSTO ENTRE UM TAMBOR DE DESCARGA E DOIS ROLOS DE PRESSÃO. A presente invenção refere-se a um dispositivo em uma máquina de cardar algodão, fibras sintéticas e similares, disposto entre um tambor de descarga e dois rolos de pressão, em que se proporciona abaixo rolo extrator um elemento estacionário, a superfície superior deste faz face com uma região do rolo extrator e a superfície dianteira desta faz face com o rolo de pressão inferior, e em que a borda entre a superfície superior e a superfície dianteira é disposta na região entre rolo extrator e os rolos de pressão e é orientada na direção em direção à pressão entre os rolos de pressão, uma manta de fibra passa através da superfície superior e, então, através de um espaço livre até a pressão entre os rolos de pressão. A fim de proporcionar um modo simples de aprimorar a orientação da manta de fibra, especialmente no caso de uma largura de trabalho relativamente grande e/ou uma velocidade de distribuição elevada, a região do elemento de suporte e orientação que faz face com o rolo de pressão inferior é constituída de tal modo que o fluxo de ar seja orientado em uma direção oposta à direção de rotação do rolo de pressão inferior.DEVICE IN A CARDING MACHINE FOR COTTON, SYNTHETIC FIBERS AND SIMILAR, ARRANGEMENT BETWEEN A DISCHARGE DRUM AND TWO PRESSURE ROLLS. The present invention relates to a device in a machine for carding cotton, synthetic fibers and the like, arranged between a discharge drum and two pressure rollers, in which a stationary element is provided below the extractor roller, the upper surface of which faces with a region of the extractor roller and the front surface thereof facing the lower pressure roller, and wherein the edge between the upper surface and the front surface is disposed in the region between the extractor roller and the pressure rollers and is oriented in the direction towards the pressure between the pressure rollers, a fiber mat passes through the upper surface and then through a gap to the pressure between the pressure rollers. In order to provide a simple way of improving the orientation of the fiber web, especially in the case of a relatively large working width and/or a high distribution speed, the region of the support and orientation element facing the bottom pressure is constructed in such a way that the air flow is oriented in a direction opposite to the direction of rotation of the bottom pressure roller.
