PATENT OFFICE.

The subject of the invention is a device on the combing machine system Heilmann to remove the mustache, which thereby differs from similar institutions, z. B. Patent No. 55232, distinguishes that the burrs in the front wool beard torn before combing it out and taking the greatest possible care of the wool fiber will.

For this purpose, the woolly beard is held by one in the cylinder comb, in front of the needle segments attached, resilient against the pliers part, covered with leather and stretched, whereupon it by an edge protruding from the jacket of the comb roller (blunt knife) is pressed into a corresponding groove in the upper part of the pliers. Through this the brittle burdock is crushed, while the woolly beard is elastic due to its elasticity Fibers and there it is between the springy, leather-covered stick and the upper part of the tongs is only clamped in such a way that it is not exposed to a tensile effect, uninjured remain.

Since the cylinder comb rotates continuously, precautions must be taken to protect the wool fiber must be made so that it is immovable in the groove of the cylinder crest The upper part of the tongs is stepping blunt knife at this moment and until it emerges from the groove, furthermore the one against the Upper part of the tongs resilient rod for the purpose of avoiding any pulling effect on the tuft stand still.

The accompanying drawing illustrates such a comb machine in the case of a Heilmann's comb machine attached device (wool detachment device), namely shows:

Fig. Ι a cross section through the comb roller of the Heilmann combing machine. with the de-climbing apparatus in the inactive state next to the feeding apparatus b,

FIG. 2 shows a longitudinal section of the comb roller according to xx of FIG.

3 shows the comb roller with the Velcro removal device in the position in which the front woolen beard is gripped and stretched by the pliers c c ¹ and the Velcro removal device (or the clamping rod d of the latter),

Fig. 4 shows the same in the position in which the mustache held by the pliers cc ¹ and stretched by the clamping rod d is pressed by the knife f ^{1 of} the unfastening device into a groove in the upper part of the pliers c and the bent end of the lever z ' ² brings the unfastening device to a standstill forces.

Fig. 5 shows the bent lever end ² .

The de-velcro device consists essentially of a clamping rod d arranged in a radially movable guide rod (U-shaped cross-section) e along the comb roller α , which is ^{covered with leather d 1} on the outer work surface and can spring in the radial direction by means of springs y placed in between. The guide rod e, which is sunk into the comb roller α and is always pressed against the stop bracket h on the comb roller by springs g, is on the

a side surface formed into a blunt edge f ¹ (so-called knife). The latter corresponds to a groove f ^{2 made} in the upper part of the forceps c . Two such described Entklettungsapparate are diametrically between the string leather segment a ¹ and the. Needle segment a ' ² arranged. The Entklettungsapparat is Bethätigt e.g. by two-armed lever disposed outside and on both sides (end surfaces) of the pinion about a horizontal axis z ^'1 are rotatably arranged and soon k of a thumb wheel, soon to be dominated by a tension spring I.

The other free end z ² of each lever which acts on the Entklettungsapparat is, as Fig. 5 shows widened and perpendicularly bent; so that this angled end in the path of protruding from the end face of the pinion end of the U z ^'2 shaped rail e lies.

The lifting device works in the following way ^:

If the pliers cc ^{1 are} closed and hold the woolly beard tightly, the de-velcro device comes under the upper part of the pliers. Now the thumb disk k begins to act on the nose i ^{s of} the lever i and as a result, by virtue of the upward lever end i ^2, presses the unfastening device upwards, so that the resilient rod d and thus the mustache are pressed against the upper part of the pliers c (Fig. 3) . In this way the woolly beard is not only held in place by the pliers, but also grasped and stretched by the upper part of the pliers and the clamped rod d.

With the continued upward movement of the lever end z ' ² , the same presses the knife f ¹ into the groove f ² in the upper part of the pliers (Fig. 4). Here, the wool of the wool beard held on both sides, because it is curled and because no tension is exerted on the end clamped between the clamping rod d and the upper part c of the pliers, is pressed into the groove f ² without tearing, while the brittle burrs are torn .

In order to avoid any pulling action and any friction between knife f ¹ and upper part c of the pliers, since this would attack the wool fiber, the stops z " ² grasp the U-shaped rail e and hold it during the time during which the knife ^" ¹ enters the groove f ² and exits it again, firmly. After the lowering of the lever ends z " ² , the rail e also steps back into the comb roller α and is placed again at the angle h by the lateral springs g .

The torn off pieces of Velcro are combed out ^{by the needle segments Λ 2.}

Claims (2)

Patent Claims: ι. A wool detachment device for combing machines with a rod fd) which is pressed resiliently against the upper part of the tongs (c) and is mounted in the comb roller (a ), characterized in that, in order to avoid any pulling action or friction which could damage the wool beard, the burrs dismembering knife ff ¹ J engages in a correspondingly designed groove (f ² ) of the upper part of the pliers (c) , so the latter itself is not touched and the Velcro dismantling device is held until the knife emerges from the groove. 2. A wool detachment device of the type described under 1 .., provided that it is operated by a lever (i) under the action of a thumb washer (k) that lifts the rod (d ) and a tension spring (I) that causes the rod (d) to retract takes place, the upturned end (i ² ) prevents the Velcro removal device from rotating with the comb roller as long as the knife (f ^l ) is in the groove (f ² ) .. 1 sheet of drawings.
