一 緒言粗紡機的主要目的是: (1) 將併條機上所產的熟條(Drawn sliver)加以牽伸後,使棉條的直徑漸漸减小,供精紡機紡出條幹均勻的細紗。 (2) 使粗紗加撚,增加其拉力,在粗纱自筒管退解時不致斷裂。 (3) 使粗紗绕在筒管上,以便利于搬動。根據以上的上的,製成同時能繞紗及加撚的錠翼。粗紗機錠翼的种类,可根據下列幾點來分: (1) 依據壓掌(Presser)的有無,分為:
An introduction The main purpose of the roving machine is: (1) After drawing the draw sliver produced on the draw frame, the diameter of the sliver is gradually reduced, and the spinning machine spins out evenly spun yarn. . (2) Twist the roving to increase its pulling force so that the roving will not break when it is withdrawn from the bobbin. (3) Wrap the roving around the bobbin to facilitate handling. According to the above, an ingot capable of winding and twisting at the same time is made. The types of roving frame rotors can be divided according to the following points: (1) According to the presence or absence of a presser, it can be divided into:
