RIEELING- YARN UPON BBBINS.'
To all whom fancy concern:
Be it known that I, FRANZ FRHLIoIr, a subject of the King of Saxony, and residing at Leipzig, in the German Empire, lhave,
As spooling is now usually carried out,-
the rotating bobbin draws the thread of yarn from the whisk, or cop, and thereby subjects the yarn to a certain stretching strain, the yarn being spooled in a tensioned condition. Owing to this strain the natural elasticity or resiliency inherent to yarn is destroyed to a larger or lesser de- It has been observed that this fact not only results in a decreased strength of the yarn, but extends its inuence in as far as yarn treated in this manner and used for manufacturing knitted or woven articles will yield less than yarn which is worked up in unstretched condition. The explanation of this phenomenon lies in the fact that with stretched yarn elongated loops are obtained in which the arched portions are cornered to some degree and, hence, more firm and unelastic. In consequence a larger quantity of yarn is required for the same article than if yarn is used which is in an unstretched condition when being worked up and which is not deprived of its natural resiliency. Furthermore, experience has shown that yarnkept loosely upon the bobbin can be preserved, without any detrimen-y tal effect, for a longer period of time than yarn which remains stretched after having been placed upon the bobbin. Because in the former case the natural resiliency of the yarn is preserved and will not be lost during a longer period of time. The natural elasticity, or resiliency is, as a matter of fact, of influence also as regards strength and durability of the looped fabrics manufactured from it; for since looped fabrics are particularly subjected to frequent stretching, the loops themselves will be less affected if the resiliency of the yarn material permits of a stretch to some degree.
The object of my invention is attained byk reeling the yarn upon the bobbin in the customary manner and-then relieving the convolutions of the reeled or wound yarn Specification of Letters Patent.
of the tension imparted to them during the reeling or winding operation immediately the bobbin is filled with yarn. This I accomplish by reducing or contracting the inner seating surface of the wound yarn body, thus permitting each convolution to recede into an 'unconstrained condition by a movement of contraction. When yarn treated in this manner is worked up into looped fabrics, the above Vmentioned advantages may then be turned to account.
The reduction or contraction of the inner seating surface of the .wound yarn body can be accomplished in various ways. A preferred construction of a suitable bobbin which allows of readily reducing or contracting the inner seat of the wound or reeled yarn body is illustrated by way of example in the accompanying drawings in which-'- Figure 1 shows the bobbin in elevation, while Fig. 2 is a sectional plan view taken on the line A--B in Fig. 1. Fig. 3 is a view` similar to Fig. 1 but showing the contrivance for reducing or contracting the said seating surface in another position.
The barrel a of the bobbin adapted for the purpose of my invention, is provided with .two longitudinal slots each of which is dimensioned to receive two bars d and c; the bars Z being iXedly mounted upon the bottoms of the slots. A bar c is pivotally connected to each of the bars Z by means of links e which keep the bar c in parallel relation to the adjoining bar Z and permit the bar c to move toward and away from the fixed bar d. 'At one end the bars c are interconnected by pivotally jointed links f, f. Vhen these links f, f are moved in the direction of the arrow l in Fig. 1, the bars c are thereby caused to move away from the bars Z till the linkse have assumed a radial position as shown in F ig. 1. -With the bars c in this position the bobbin is ready to be lled with yarn.
The bobbin rotating, the thread of yarn will be passed around the bars c and a portion of the circumference of the bobbin barrel. When the reeling operation is completed,viz., when the bobbin is filled with yarn, the jointed links f, f are drawn in the direction of the arrow 2 in Fig. 3, whereby the bars c are caused to move toward the bars b till they are within the circumference of the bobbin barrel on which the wound yarn body will then be seated.
