Abstract

"DISPOSITIVO DE ESTIRAMENTO PARA MáQUINA DE FIAçãO". A presente invenção refere-se ao dispositivo de estiramento para uma estação de fiação (1) compreende um par de roletes de alimentação (2, 3), um par de roletes de sustentação de correia transportadora (10, 11) a jusante do par de roletes de alimentação (2, 3) um par de correias transportadoras (8, 9) enroladas em torno dos referidos roletes de sustentação de correias transportadoras (10, 11), curva de retorno e dispositivos de guia (14, 18, 31, 15), que condicionam os cursos das correias transportadoras (8, 9) para criar um esticador de contato (17), ao longo do qual as referidas correias transportadoras (8, 9) são fixadas uma à outra, criando um guia para uma banda (5). Um par de roletes de estiramento (21, 22) é colocado a jusante do esticador de contato (17) do par de correias transportadoras (8, 9). Uma área de pré-estiramento é criada entre uma fenda de tensionamento (4) do par de roletes de alimentação (2, 3) e uma fenda de tensionamento de entrada (7) das referidas correias transportadoras (8,9) entre os referidos roletes de sustentação de correias transportadoras (10, 11). Um condutor de estiramento de área é criado entre o par de roletes de sustentação de correias transportadoras (10, 11) e o par de roletes de estiramento (21, 22), em que o ângulo (<244>) que é definido entre uma linha de junção reta ou paralelo entre os eixos de rotação (26, 28) do par de roletes de sustentação de correias transportadoras (10, 11) e uma linha de junção plana ou reta entre os eixos de rotação (27, 29) do par de roletes de estiramento (21, 22) é maior do que 100."STRETCH DEVICE FOR SPINNING MACHINE". The present invention relates to the stretching device for a spinning station (1) comprising a pair of feed rollers (2, 3), a pair of conveyor belt holding rollers (10, 11) downstream of the feed rollers (2, 3) a pair of conveyor belts (8, 9) wrapped around said conveyor belt support rollers (10, 11), return curve and guide devices (14, 18, 31, 15 ), which condition the travels of the conveyor belts (8, 9) to create a contact stretcher (17), along which said conveyor belts (8, 9) are attached to each other, creating a guide for a band ( 5). A pair of stretch rollers (21, 22) are placed downstream of the contact tensioner (17) of the conveyor belt pair (8, 9). A pre-stretch area is created between a tensioning slot (4) of the feed roller pair (2, 3) and an inlet tensioning slot (7) of said conveyor belts (8,9) between said rollers. of supporting conveyor belts (10, 11). An area stretch conductor is created between the pair of conveyor belt support rollers (10, 11) and the pair of stretch rollers (21, 22), wherein the angle (?) Which is defined between a straight or parallel junction line between the rotation axes (26, 28) of the conveyor belt pair (10, 11) and a flat or straight junction line between the rotation axes (27, 29) of the pair of stretch rollers (21, 22) is greater than 100.
