from the rules at high speed, e.g. 1 ) $ d "iis ^ roÜCC m per minute and gathered into a dbrang, but if they slide a suitable guide. Then the strand of thread is wound on a rapidly rotating forming tube Dicice of the threads to be produced, the shaped tube is set in circulation at a speed of about 2.üuu to 15.GUÜ rpm.

During the production of the thread strand, ice takes place in Yerdrillen, whereby a binding agent and a lubricant, e.g. Starch and a vegetable, ul, Destehenaer .kle glue is applied before the individual load, together to form an otang and wound on the ear to connect the threads with each other and to maintain the unity of the thread strand. The glue also reduces the abrasion of the threads that have been pulled thinner. The single strand of thread is usually on. The dohr is wound up at an angle, so that the following threads cross each other and do not run parallel to each other. This makes it easier to take the cord from the ear. The course of the drill is given to the strand after the threads have been knotted together to form an id strand and before this is wound onto the tube, a suitable guide is used to soften the strand.

never manufacture u-lasfadeüs-crangen according to the above Procedure is limited in that the speed the chain formation depends on the speed, with which the individual strand is wound up on the shaped tube, obviously the production could be increased significantly, if several strands of thread are on the same jiorm tube at the same time

could be wound up and unwound as separate strands.

It has been proposed to produce a -Number of strands at a single 2 ^V or MGE bung station and to wind all of the strands to form a single pipe. American Patent Specification No. 2,386,158 discloses a method according to which the threads are combined into two groups, the threads of each group being gathered into two separate strands. The strands are then simultaneously wound onto a shaped tube and guided in a seal by a pin wheel guide. The strands are twisted on the forming tube essentially parallel to one another and closely spaced. In the older method according to American patent specification 2,386,158 and especially on the inde- der-trajectory, the strands often overlap and lie closely against one another over a substantial part of their course,

The strands are wound up on the shaped tube at a relatively high speed, so that the adhesive applied to the individual threads is still moist when the strands are wound onto the shaped tube. but brought vderden the strands of a substantial part of its length into intimate contact with one another, they remain permanently in each strand, In ameriranischeη Patent Mr, 3 Ο56 711 a method is disclosed for the separate strands as well to each other are liable as the individual would find can be united with one another by bringing them together in intimate contact over part of their length and being wound up on a shaped tube.

has a significant effect when unwinding the separate strands from the shaped tube, the tensions under which the strands are dyed stand at appropriate points along their length, from each other, so the strands seek to unwind unevenly from the I'ormrohr. As is believed, uneven tension of the strands causes groups of turns to be made at once instead only one vfindung is removed from the shaped tube at a time.

Both the sticking of the strands to one another and the uneven tension with which the strands are wound on the W- shaped tube cause the strands to tear and the unwinding to be interrupted. It is therefore desirable to lay the strands on the shaped tube in such a way that they have little contact with one another and thus little opportunity to stick to one another; it is also desirable to open the strands to lay down the drill pipe so that

the individual strands are essentially under the same tension and can be unwound quickly and easily, without deducting several turns at the same time.

The invention has shown that when several strands are wound onto a single shaped tube in such a way, that the strands are on top of each other, that they are

ύ \. specific temporal relationship to each other and are then wound onto a forming tube, a package of wound strands can be produced from which the strands can be easily unwound individually. jYes Winding a number of strands in the one described above

and run over a transverse guide device, designated as a whole by 36, when they are wound up on the forming tube 20. The transverse guide device 36 has a cylindrical body part 38 with two end walls 40 and 42 flanged on. These consist of two spirally formed and complementary guide members 44 and 46, to which the body part 38 is formed. The guide members 44 and 46 extend over a little more than 180 ° of a full turn. The end of one guide link lies inward of the other end of the other guide link so that the guide links 44 and 44 overlap one another at the ends. The. Cross guide device 36 can be made from any abrasion resistant material. The transverse guide device 36 is attached to a well 48 and rotates with it. The shaft 48 is mounted parallel to the shaft 5 ° which carries the shaped tube 20. The winding device 22 carries both shafts 48 and 50 and has the suitable means to set the shafts 48 and 50 in rotation at preselected speeds and to move the shaft 50 or shaft 48 or both shafts axially in order to move the strands 26 and 28 to be distributed in a suitable manner during winding on the forming tube 20. For example, the ftlie 50 and the forming tube 20 back and forth in the manner and forth "discloses ■■" as itt'der American patent specification 3,041,662.

is wound up lying over the strand 28. The strands 26 and 28 are of the complementary guide members 44 and 46 of the transverse exercise device 36 laterally with respect to one another emotional. The manner in which the strands 26 and 28 are laid down on the forming tube 20 is shown in FIGS. 3 and shown. In FIG. 3, the vertical lines A, B, G, D and E indicate the same location of the strands 26 and 28 as in FIG Figures 4-7 shown. The guide members 44 and 46 extend but an angle of 180 ° and complement each other

W mutually so that the strands 26 and 28 cross each other twice with one full revolution of the guide device 36 and form an "8" in plan view.

Figures 4-7 show the relative position of the strands 26 and 28 and their lateral direction of movement when the i ^ uerfUhrungsvorrichtung 36 extend one full turn. In 4 the strands 26 and 28 move laterally away from each other. The guide member 44 pushes the strand 28 in the direction of the flanged side wall 42, while the guide member 46 moves the strand 26 against the side wall 40 pushes. The relative position of the strands 26 and 28 is shown at A in FIG. When the transverse guide device rotates The strands 26 and 28 have their lateral ones over 90 ° The direction of movement is reversed with respect to one another and now move under the action of the guide members 44 and towards each other. The relative position of the strands 26 and 28 according to FIG. 5 is shown at B in FIG. Drive the guide a rotation but a further 90 °, then the. strand 26 crosses the strand 28, and the strands 26 and 28 move away from each other again, as shown in Fig. 6-

The position of the strands 26 and 28 in relation to each other according to the Fig. 6 is shown in the Fig. 3 at ύ. Ivach i'ig.7 of the strands in turn have reversed their direction of movement, so that they again approach each other, as shown in the I ^H '"is.3 at -U. In the embodiment shown at G and D have the location strands therefore reaches their greatest lateral distance from one another and move towards one another again. In FIG. 3, the line E shows the same position of the strands 26 and 20 that is shown at A. In this position, the implementation procedure has

direction turned into the position shown in i'ig.4-. ^ From the above it can be seen that the strand 26 the S ■ Strand 28 during one full revolution of the guide device 36 crossed twice.

The relative speeds of the jj'ormrohres and the ^ ueridhrungsvorrichtung 36 are determined so that the strand 26 traverses strand 28 at a substantial angle, so aass between strands 26 and 2Ö at the crossing point only there is a very small contact area. The strands 26 and 28 do not try to stick to each other at the crossing point ben, since the contact area between the strands is only slightly longer than is the diameter of the strands.

are laid down crosswise.

By placing strands 26 and 2 & on opposite sides Pages of the '^ uerflihrungsvorrichtung 36 is on the Strands exerted essentially the same tension, with strands 26 and 28 ironing the greatest lateral distance from one another in this way essentially the same tension is exerted on both strands. Likewise, on both strands is essentially the exercised the same pull when they cross each other, rfie already explained, the strands unwind more evenly from the forming tube when both strands are essentially below the same tension.

It is also possible to use the described ikerkniale Invention to use to make more than two strands on a single Wind up the shaped tube and unwind it separately and at the same time.
