    Abstract: A yarn tension control device for controlling the tension of yarn being longitudinally advanced having two movable yarn guide members with spaced guide pins alternately engaged by the longitudinally travelling yarn. One of the yarn guide members is pivotally mounted to move its guide pins across the yarn path and has a pin or roller mounted spaced from its pivot and is balanced by a balancing weight. A pivotally mounted control cam has a balancing weight and a laterally extending arm with a biasing weight adjustably positioned on the arm. The control cam has a cam profile in contact with the pin or roller on the first yarn guide member and the biasing weight biases this profile into engagement with the roller or pin to pivot the first yarn guide member in a desired direction. The portion of the arcuate cam profile nearest its pivot is concave, a middle portion thereof is nearly straight, and the portion of the cam profile furthest from the control cam pivot is convex. Thus as the first yarn guide member moves away from the second yarn guide member the biasing is decreased.

    Abstract translation: 一种纱线张力控制装置，用于控制纵向前进的纱线张力，该纱线张力控制装置具有两个可动纱线引导部件，其间隔开的引导销由纵向移动的纱线交替地接合。 纱线引导构件中的一个枢转地安装成使其引导销横过纱线路径移动，并且具有与其枢轴间隔开并由平衡重平衡的销或滚子。 枢轴安装的控制凸轮具有平衡重和横向延伸的臂，其中偏置重量可调节地定位在臂上。 控制凸轮具有与第一纱线引导构件上的销或辊接触的凸轮轮廓，并且偏压重物偏压该轮廓以与辊或销接合，以使第一纱线引导构件沿期望的方向枢转。 弓形凸轮轮廓最靠近其枢轴的部分是凹形的，其中间部分几乎是直的，凸轮轮廓部分距控制凸轮枢轴最远的部分是凸的。 因此，由于第一纱线引导部件离开第二纱线引导部件移动，所以偏压减小。

    Abstract: A yarn tension control apparatus comprising a first feed roll having a substantial conically tapered yarn engaging roll surface, driven at a predetermined r.p.m., a second feed roll having a substantially conically tapered yarn engaging roll surface, the second feed roll positioned in spaced-apart relation with the first feed roll for receiving a yarn wrapped successively around a circumference defined collectively by opposed surfaces of the first and second rolls from a yarn infeed position axially along the first and second rolls to a yarn exit position. The first and second feed rolls are aligned relative to each other so that the collectively defined circumference any any point on the yarn engaging surfaces of the first and second rolls is greater than the collectively defined circumference in one direction along the axis of rotation of the rolls, and less than the collectively defined circumference in the other direction along the axis of rotation of the rolls. An elongate tension arm is positioned between and along the length of the first and second rolls and a plurality of yarn guides positioned in the tension arm along the length thereof for receiving successive wraps of yarn. The tension are moves along the length of the rolls in response to changes in tension of the yarn to a yarn infeed position or increased roll diameter in response to an increase in tension on the yarn and to a position of decreased roll diameter in response to a decrease in tension on the yarn.

    Abstract: A ball tension device for horizontal yarn comprising generally a body defining a vertical channel within which one or more balls can be positioned to vary yarn tension. A pair of horizontally aligned openings communicate with the bottom of the channel to provide for yarn inlet and outlet as the yarn passes through the device. Similar, ceramic inserts line the inlet and outlet openings and are angularly downwardly inclined to define a pair of opposed, angularly inclined conduits through which the yarn horizontally passes in the tensioning procedure.
