Description

Dec. 25, 1951 Filed March 19, 1948 INVENTOR JAN MORAVEC ATTORNEY Patented Dec. 25, 1951 DEVICE FOR DRAWING OFF SPUN FIBRES Jan Moravec, Zlin, Czechoslovakia, assignor to Bata, narodni podnik, Zlin, Czechoslovakia Application March 19, 1948, Serial No. 15,753 In Czechoslovakia March 27, 1947 3 Claims. (CL 28-715) This invention relates to a simple and effective device for guidance of spun fibres during their drawing off.
It is usual to lead a bundle or group of spun fibres, obtained for example by the'dry spinning of polyamides or the like, to a take-uproller,
.and to wind them upon it in a number of helical windings, Whereafter the bundle of fibres is wound upon a reel or bobbin, being simultane-' ously stretched if so desired. For high spinning speeds, it is very important to provide easy guide ance of the bundle of fibres upon the take-up roller continually.
The object of the invention is to provide a fibre-spacing holder and means for winding the ingoing fibres around both the take up roller and the holder so that they are formed in properly spacedhelical windings. In this manner the required windings are formed, their number being suflicient to prevent the fibres from sliding in the direction of the pull, when being drawn off.
The invention is illustrated, by way of example, in the accompanying drawing, which is an elevation, partly in section, of a take up roller and associated parts.
The device according to the invention consists of a take up roller 1 journalled on a stationarily supported bearing or journal member the bottom of which is indicated by 4. The roller I is continuously rotated on the member 4 by a beltdriven pulley 8 which is firmly connected with the take up roller l. The member 4 is extended above the take up roller l as a screw 4'. The axis of this screw is identical with the axis of rotation of the take up roller I. A stationary fibrespacing holder 2 parallel with the axis of the take up roller is secured to the member 4, being formed with grooves for locating the fibres. Through the stationary hollow member 4 extends a turnable shaft 1 which can be turned by means of a wheel 6 secured to its lower end, the shaft I oeing also axially slidable through the journal member 4. The upper end of the shaft 1 is extended as a finger 9 with a terminal eye 9'. Through this eye 9 passes a fibre-guiding arm 3 with a terminal eyelet 3, through which the ingoing fibre or bundle of fibres is drawn. The guiding arm 3 is integral with a boss made as a nut which engages the screw 4'.
When the fibres are drawn off from the usual spinneret (not shown) in the direction of the arrow to any usual reel or bobbin (not shown) it is possible to form them into a sufficient number of windings on the take up roller to prevent 2 the fibres from sliding in the direction of the pull. This is performed, after the fibres have been passed through the eyelet 3', by 'tuming the wheel 6 in the opposite direction to that of the take up roller as many revolutions as the number of windings considered necessary to prevent the fibres from sliding in the direction of the pull. When the wheel 6 is turned, the finger 9 carries the guiding arm 3 around both the rotating take up roller and the stationary holder 2, the shaft 1 simultaneously sliding upwards. The eyelet 3' thus follows the helical path of the thread of the screw 4, so that the fibres are helically wound upon the take up roller l and the holder 2, which holds them properly spaced apart.
When a satisfactory frictional drag is applied to the fibres .by the ultimately selected number of windings around the take up roller and the holder, turning of the wheel 6 is stopped. Thereafter, the drawing ofi operation is carried on, the take up roller l revolving as usual.
In the example, the screw 4 is co-axial with the take up roller I but it is sufiicient if they have parallel axes. Instead of the .screw device shown, the arm 3 could be made as a pivotal member and arrangements could be made to lift the arm manually about its pivot as the arm rotates; the same eiiect could be obtained by making the arm of the guide of flexible material and by manually lifting it during the rotary movement.
An advantage of the arrangement according to the invention consists in the very easy and-very quick manner of guidance of the bundle of fibres upon the take up roller, thus allowing the operation even at high velocities of drawing on.
