摘要:
Apparatus for winding spools with textile yarns comprising a yoke of two arms which are secured on a common shaft and which terminate in aligned spool-mounts. The portion of the shaft between the mounting points of the arms acts as an elastic or torsion-bar system to permit the arms and their spool-mounts to yield to accommodate static or dynamic variations in the spool.

A winding head for the winding freshly spun and/or stretched synthetic threads running continuously at a high speed onto a bobbin securely held by means of a chuck which bobbin and its winding are driven by a drive roller in steady rotation, and a fluid operated system for operating the chuck, for moving and pressing of the drive roller against the bobbin, and for the braking of the chuck shaft.

Winding device with drive-roller drive for winding endless threads on a bobbin tube securely held by means of a chuck, with a pressure-operated rod axially movable in the chuck for releasing the chuck and an electric or a pneumatic or hydraulic drive motor for starting rotation of the empty bobbin or providing an additional drive moment in the chuck shaft.

There is disclosed a device for reducing the contact pressure of a bobbin contacting a drive drum of a winding arrangement for threads or the like. The inventive device comprises a machine frame, a pivotable bobbin support arm and loading spring means cooperating with said bobbin support arm for providing the bobbin contact pressure. A lever is pivotably arranged on the machine frame and a guide element determines the position of said lever. According to an important aspect of the invention, the loading spring means is attached to the bobbin support arm in the vicinity of the bobbin and is hinged to the machine frame via the aforesaid lever, so that the guide element of the bobbin support arm deflects this lever and the loading spring means over a certain distance while the bobbin support arm is tilted.

A METHOD AND APPARATUS FOR WINDING ENDLESS YARNS ON A SPOOL IS DISCLOSED, THE METHOD AND APPARATUS PROVIDING A WINDING HAVING A CONSTANT WINDING RATIO, I.E., A SOCALLED "PRECISION WINDING," WHEREIN THE NUMBER OF SPOOL REVOLUTIONS PER THREAD-GUIDE STROKE IN A CROSS WINDING ARRANGEMENT REMAINS CONSTANT. THE INVENTIVE METHOD AND APPARATUS IS APPLICABLE FOR WINDING AN ENDLESS YARN FED AT A CONSTANT SPEED ONTO A SPOOL DRIVEN AT ITS CIRCUMFERENCE BY A DRIVE CYLINDER. THE THREAD IS FED TO THE SPOOL VIA A GROOVED DRUM OR A THREAD-GUIDE OPERATED BY A GROOVED DRUM. THE DRIVE CYLINDER IS DRIVEN IN KNOWN MANNER AT A CONSTANT SPEED. YET, THE GROOVED DRUM ITSELF IS DRIVEN IN DEPENDENCE UPON AND AS A FUNCTION OF THE NUMBER OF ROTATIONS OF THE YARN SPOOL OR THE DIAMETER OF THE YARN SPOOL AND THUS A CONSTANT WINDING RATIO IS MAINTAINED.
摘要:
A device for winding textile threads in which the clamping spindle, upon which a bobbin cylinder is mounted, extends with its ends beyond the bobbin and loosely engages with annular grooves in these ends the circumferences of two pairs of circular supporting discs, each pair of which is mounted on a horizontal shaft, whereby these two shafts are parallel and spaced from each other and are arranged in the same horizontal plane. A motordriven cylindrical roll is arranged above the bobbin cylinder and frictionally engages the same and later the bobbin formed by the thread which is conducted from above by a horizontally reciprocating thread guide-along a portion of the circumference of the cylindrical roll-and then onto said bobbin cylinder.
