7 Claims. (Cl. 242-18) This invention relates to textile machines and relates more particularly to an improvement in the take-up means of textile machines on which are produced cheeses and like packages of yarn.

In winding or twisting and winding machines for producing yarn packages, as heretofore commonly constructed, the yarn was wound into package formed by means of a cork-covered roll or drum which frictionally rotated the yarn package. The positively driven cork-covered roll or drum often caused excessive friction'on the yarn being wound which resulted in broken filaments and hairy yarns. It is, accordingly, an important object of this invention to provide an improved take-up means for a winding or twisting and winding machine which will be free from the above mentioned. and other disadvantages, and

. which will be especially simple in construction and ,efilcient and inexpensive in operation.

Another objectof this invention is the provision of a winding or twisting and winding machine for producing packages of yarnwhich are perfectly wound as to the density and traverse and which will be substantially free from broken filaments.

A further object'of this invention is the provision in a winding or twisting and winding machine of an improved take-up means wherein the package being wound is directly driven.

Other objects of this invention, together with certain details of construction and combinations of parts, will appear from the following detailed description. 7

In the accompanying drawings wherein a Preferred embodiment of my invention is shown,

Figure 1 is a front elevational view of a portion of a twisting and winding machine in which my invention is embodied, and

Figure 2 is an end elevational view, partly in section, of Figure 1.

'Like reference numerals indicate .like parts throughout both views of the drawings.

Referring to Figure lot the drawings, there are shown some of the twisting and winding units generally making up a machine of this type. However, in order to simplify the disclosure of my invention, the description will be particularly directed to one of said twisting and winding units such as is shown in Figure 2.

The yarn 3 to be twisted and wound into the form of a cheese 4 is drawn from a bobbin 5 drivingly supported by spindle 6 driven by any suitable means, such as a motor (not shown) through a belt or tape I passing over whorl 8 and idler pulley 3 and driving pulley II, which pulleys are u 'of the spindle, as is well understood in the art.

. a 2 a suitably supported on, the machineframework. The yarn 3 is drawn from' bobbin 5 througha fixed guide l2 supported on a cross-piece l3 attached to the framework of the machine, said guide eye being positioned centrally or substantially centrally over the spindle 6. From the guide eye l2 the yarn passes from a traverse guide I! carried by a traversing rod l5 whichtraverses the yarn on to the cheese 4.

The cheese 4 is wound on a yarn support or core It held on a mandrel I! "provided with spring. fingers H! for retaining the core on the mandrel.

The mandrel I'lis attached to a support l9 having integral therewith a sprocket 2|, the mandrel and support assembly being mounted on ball bearings 22 mounted on a spindle blade 23 joumalled in a bearing member 24 in the end of an arm 25. The sprocket 2| is connected by means of an articulated chain 26 to the sprocket 21 mounted on the shaft 28 driven by the output shaft of a positive, infinitely variable speed transmission (not shown) such as the one known as a P. I, V?

gear manufactured by the Link-Belt 00. As is well known, such a variable speed drive is so con- 5 structed and arranged that changes in speed may .be effected continuously during the operation thereof. By the use of such a Variable speed arrangement, the cheese 4 being rotated by the mandrel l1 may be given the constant peripheral speed which is necessary to produce satisfactory cheeses. The shaft 28 is journalled in suitable j bearings carried on the upper extremities of standards 28' supported on the framework of the machine.

For taking up the yarn 3 on to the package to form the cheese 4, the mandrel II with a core or yarn support It thereon is placed in contact with a polished steel drum 2!! having roller bearings 3| rotatably mounted on a stationary shaft 32, the rotation of the mandrel also rotating the drum 29. The use of the idler drum 29 for supporting the package being. wound is advantageous since it makes for very little friction on the yarn being wound thereby substantially eliminating broken filaments and hairy yarn.

.As is shown in the drawings, means may be provided for lowering the package support on to the yarn and for automatically lifting the cheese. Such means is generally indicated by reference numeral 33 and is mqunted on the framework of the machine, being attached at one end to arm 25 and at the other end to a foot pedal 33'. A spindle brake' generally indicated by reference numeral 3 is provided for stopping the rotation The reference numeral 35 indicates drop wires which may be employed to stop the rotation of the yarn package upon the breaking or failure of the yarn.

tating the package being wound at a constant peripheral speed and idler means for supporting said package being wound during the winding thereof.

5. Apparatus for winding textile packages, comprising a mandrel adapted to support the package being wound, means for positively and directly driving said mandrel at a constant peripheral speed, and a 'freely rotatable polished steel drum for supporting said package being wound during the rotation thereof.

6. Apparatus for winding textile packages, comprising a mandrel for supporting the package being wound, means for positively driving said mandrel at a constant peripheral speed, said means comprising a variable speed drive means, a sprocket attached to aid mandrel, a second sprocket attached to said variable speed drive means and an articulated chain connecting said sprockets, and a freely rotatable drum for sup-' porting said package being wound during the winding thereof. 7

'7. Apparatus for winding textile packages, comprising a mandrel for supporting the package being wound, means for positively driving said mandrel at a constant peripheral speed, said means comprising a variable speed motor, a sprocket attached to said mandrel, a second 7 sprocket attached to the output shaft of said variable speed motor and an articulated chain connecting said sprockets, and a freely rotatable drum for supporting said package being wound during the winding thereof.
