Triptych and process for its manufacture

The strands known up to now are opened Reel machines divided into more or less Umbelnde so wiggled that they su «unwinding on rotatable Reels are radially unwound nuts. Your paden must therefore be drawn tangentially by the reel set in rotation with the pull of the thread to be unwound will. This is the reason that especially with thinner, i.e. for weaker yarns the skein weight should only be small

careful, slow start-up has its slightest impact Tear resistance set a larger weight in rotation would have to. For this reason the i>; wl: nt, the ütrangen limited because of the cooling capacity of bathing.

In spite of this, it has already been suggested in various ways sought to be able to increase the strand weight. On the one hand succeeded in doing this to a certain extent by using the winding machines with sensitive starting, as well as have been equipped with useful braking devices. On the one hand, this means fewer knots and longer running times and ultimately also to reduce the manipulation work. On the other hand were to To be able to work with larger strand weights, the payoff reels increased so that it was possible to work at a lower speed. With such efforts came you actually rely on higher weight units per strand, especially with thicker yarns, such as hand knitting yarns. In the twisting mill, the acceptance weights However, the spindle can be increased so much that reel weights of two to more kilograms can be achieved. Must be used for dyeing and other finishing However, these bobbins are again divided into several strands, and so is the large thread length obtained several partial lengths are cut, which is a quality

The subject of the present invention is now "in a novel wound large winding, which up to can have several kilograms in one thread length. The most important feature of this wrap is that it does not have to be rotated to unwind, but that its thread can be withdrawn axially overhead of the stationary lap at great speed. The procedure to build such a ureitwlckela provides that first a beginning with a conical exit wound and that from this cone from dor winding in continuously See shifting cone bat after the third is wrapped in a cross. This creates a constant Cone like a head, only here on a large one Circumference and with cross-laying »This cone then enables unwinding the thread from the stationary, round stretched out Pull off the wide lap axially from this side of the cone with a large thread curl.

The beginning of the cone can be in different ways are executed. In the embodiment shown, this beginning on the mechanically easiest to perform Art shown. This should then be explained in more detail in the special description with a drawing.

The crossing ratio must also match the purpose and but should be adapted to the material to be wound throw not explained in detail here.

This combination of the cone curl in the form of a strand and the securing of the conical cross-ply twisting through the longitudinally stable ligation large step in terms of labor savings through larger padding teeth when winding down and an improvement in quality due to the significantly longer thread lengths without a knot point.

Ks are already similar-looking »la diameters but much smaller laps are known which are pulled off axially for unwinding, such as the spider cakes, how they are made with the artificial silk spin process. However, this type of winding is not in conical layers.

The cloud layer, with such a large diameter, would not withstand any treatment, if the method for its structure were not also provided with a longitudinally stabilized , finely curved subdivision. This subdivision should have at least three subdivision sides 3 in width per crossing lane (see Flg. 2) and the circumference should be repeated a number of times. The subdivision elements can be made from stable material such as wire, from cotton or from plastic otter, also made of cord. The subdivision elements 3 ^^ za ^ e ^ ® i ^ ig.ia and 2b show an essentially U-shaped cross-section and the element elements 3 are connected to one another by connecting members 3a and thus form an interlinking connecting member. The most important moaent of this subdivision is that the subdivision elements are connected to one another in a stable manner. In Fig. 2a / 8b a rigid subdivision element 3 * * is shown, in which the subdivision elements 3 are made of stainless steel wire in pore of connecting wire brackets. These

By doing essentially one pin-shaped absalus organs 5 through the aligned tips of the subdivision elements 3 in the cavity enclosed by the Wiokelsohioht the elements 3 are secured against falling out.

Flg. 4 to 7 schematically show an example the implementation of such a termination. The procedure provides that one Reel machine in a needle bed like that of a flat knitting machine (not shown) 8 needles with special Hooks and feet are arranged, with a Needle lock (not shown) the needles on their kiss are individually driven from the outside through the winding layer 2, so that their hook heads 8 in that of the Wickelsohioht enclosed cavity protrude in a straight line. This special hook is then used by means of a special Durehführungsorganes 9 a lower waist thread 7 coming from a bobbin and carried out at the end of the Row of needles attached to a clamping device (not shown). Then use the needle lock from this side one needle after the other pulled back through the wrapping layer, as FIG. 7 shows, so that from each needle a thread loop 7a (FIG. 7) around daa between two needles lying winding part is pulled. That way will from each needle a loop 7b is pulled through the winding layer and these loops are then together with flexible but longitudinally stable organs 16 connected.

In the example of FIGS. 6 and 7, the sole rings awaken a long-lasting connection »smell an upper one and a lower special plastic band l6 through a roll spot welding device The roll point welding device consists of a white roller 17 and a counter pressure roller 18 (Flg. 6).

The whole Schwelsselnriohtung as well as the supply rolls of the Sohweissbändehen 16 are on a slide along the needles or the row of loops and special guide slots in the form of guide slots ensure that the two smoldering ligaments come to lie exactly one above the other on both sides of the loops. The welding roller has on its circumference at certain intervals electrically heatable bosses 17a, which under pressure and worms the swelling points between the Create ribbon. These simmering points are so close on top of each other * that there is at least 1 welding point in each loop. To safely meet this requirement * the loops are spread out beforehand by a spreader plate 15 with teeth 15a.

The task of wedge I3 is * that when * the bar 12 is pressed in the direction of the arrow (Fig. 5), the ends of the strand are first pushed apart so that the two end noodles hit the void when pushed forward. In this way they each pull an identical loop 7b (Fig. 7) between the winding layer and the cutting device, while the thread 7 rolls around the cutting device

1st. If all soles 7b are then attached to the rigid organ, the underside thread 7 continuous over the entire width of the reel soles is cut in the cutting devices lh. In addition, the stabilization joints are also cut through by special cutting devices, so that the strands are now separately ready for removal. Duroh special organs, the beginning and the end thread of each wrap are sewn into the stabilizing organs. It is a matter of course that these organs of stabilization, which should hold the ends, are marked by a special color, distinguishing them from the other organs of stabilization of the coil. This enables the starting and ending threads of the Wiokela to be found immediately for unwinding the lap.
