Title: Yarn tension devices
IPC: B65H59/38
Filed: 1951-04-30
Abstract: 691,152. Yarn tensioning device. CELANESE CORPORATION OF AMERICA. April 30, 1951 [May 2, 1950], No. 10084/51. Class 120(ii) A yarn tensioning device comprises a friction surface, a pair of fixed yarn guides and an intermediate yarn guide angularly adjustable relative to said fixed guides so as to bring the yarn into contact with said surface to an adjustable extent said yarn guides being spaced from one another along the axis of adjustment. The embodiment shown consists of two tubes 19 and 21 having plugs 22 and 24 press-fitted into their ends and separated from one another by a further plug 26 having bosses 27 and 28 projecting into the tubes 19 and 21, said plug 26 being freely rotatable with respect to said tubes. Pigtail yarn guides 29, 31 and 32 are fastened to the plugs, the guides 29 and 31 being aligned one with the other. The plug 26 is secured to a shaft 33 carried in bearings 34 and having a bevel gear 36 at its upper end which meshes with a bevel gear segment 37 connected by a rod 39 to a part of the yarn traversing mechanism of a winding machine. As the winding proceeds, the traversing mechanism rocks and so rotates the segment 37 which in turn rotates shaft 33 and therefore guide 32. The arrangement is such that as the rate of take-up of yarn increases, the wrap of yarn around the tubes 19 and 21 decreases so compensating for the increase in tension caused by the increase in the take-up rate, and thus maintaining the tension in the yarn constant throughout the winding operation.
