Abstract
Abstract The method and apparatus of this invention are illustrated in an embodiment of apparatus for controlling the tension of linear materials between material feeding and collecting means. Means are provided for collecting linear material into a package, including means for controlling the rate of collection. Means are shown for delivering the linear material to the collecting means, including means for controlling the rate of delivery. A predetermined tension is provided on the linear material between the delivering and collecting means by yieldingly biasing the linear material away from a straight path between the delivering and collecting means. The position of the biasing means is sensed as a measure of and to adjust the relative rates of delivery and collection to maintain the desired tension on the linear material. The rate of movement of the biasing means is selectively controlled by means responsive to increasing tension on the linear material for retarding the rate of movement of the biasing means during the final portion of travel in response to increased tension, thereby substantially preventing overadjustment of the rates of delivery and collection of the linear material. Means responsive to decreasing tension inhibit the action of the retarding means to enable the biasing means to maintain contact with the linear material to prevent slack from developing and to prevent loss of control of the feeding and collection of the linear materials.
