Pile divider.

In the previously known pile healers, in which two to achieve the pile ribbons In the same interstices with correspondingly wide scraper belts clad take-off rollers are arranged on the roving card, the upper one of which is its scraper belts corresponding wide Vliefband is removed from the card, while the one on the same . any fleece strips left behind are removed from the lower doffing roller, it is to be designated as an inconvenience, that the Vliefband, which the upper taker supplies are of significantly better quality than those of the customer below.

This circumstance is due to the fact that the upper buyer not only ■ the width of its fittings decreases certain strips, but also the longer, transverse fibers of the strips intended for the lower doffer and carries with it. As a result, the tapes produced by the upper doffer settle composed of many long fibers, while the ligaments of the lower consumer are almost exclusively formed from short fibers.

To remedy this disadvantage is the purpose of the present invention, according to which To achieve completely uniform Vliefband every Vliefband half off one strip removed from the upper stripper roller and to the other half consists of a strip removed from the lower roller.

The pile healer is shown in the accompanying drawing.

Fig. Ι shows the same in cross section and

Fig. 2 in outline.

Fig. 3 shows a part of the scratching tape used in cross section.

4 and 5 show a particular embodiment in cross-section and longitudinal section of the pile healer.

The doffing rollers BC are stored with the rollers EF assigned to them in a suitable frame in front of the reel A. Both doffer rollers are with the rollers E and F by narrow, endless scraper belts GG ¹ respectively. HH ¹ connected, which are arranged on the doffing rollers in gaps, the width of which is adapted to the width of the scraper belt, which causes the scraper bands provided offset to one another on the doffers BC to act in uninterrupted sequence over the entire width of the card. As a result of the alternating guiding of the scraper belts by the customers over the rollers EF , a belt from the upper customer always comes to lie directly next to a belt from the lower one, and so both are combined into a belt whose width is twice that of the previous one The arrangement of the doffing rollers on the same open scraper belts can suitably coincide, for which purpose it is necessary that the individual endless scraper belts are half as wide and twice as numbered as in the known arrangement mentioned.

The BC respectively by the rollers. by the scratching belts running over the same

Claims (1)

the reel A combed fleece strips are respectively through the scraper belts GG ^1. HH ^{1 of} the roller E respectively. F fed - where the fleece strip coming from the upper doffer is combined with the one from the lower one and is fed to the terry cloth J as a uniform band by the small doffing rollers. As a result of this arrangement, tapes are of a perfectly uniform composition achieved by half of each band from a good non-woven strip supplied by the upper customer and the other half is composed of a less good fleece strip coming from the lower consumer. The scratching belt K ¹ can event to give it sufficient strength as an endless connecting belt. To give drive belt, it should be provided with a leather pad K (Fig. 3). To keep the scraper belts at the same distance from each other during their movement, two cross bars B ¹ B ² , C ¹ C ² , E ¹ E ² and F ¹ F ^{2 are} provided for each roller, which are in bearings on the frame jaws next to the rollers and immediately above respectively. are stored under the scraping tapes. The cross bars carry disks, rollers, pins or the like at equal intervals, which take up the scraper belts between them and thus prevent them from moving sideways. ₍ The tensioning of the scraper belts can take place on the one hand by removing the rollers EF from the rollers BC by screwing the bearing jaws D divided at D ¹ more or less apart by screws Z) ^2. On the other hand, the same effect can be achieved by appropriate adjustment of the cross bars B ¹ B ² E-F ' ² in their bearing slots. To guide the scraper belts, part plates L can be used instead of the cross bars with their disks, as shown in FIGS. 4 and 5. Such partial plates are provided between all the scraping belts lying next to one another and are held at certain distances from one another ^{by means of short sleeves Af 1} , which are arranged on continuous transverse rods M. Pa τ ε ν τ - A ν s ρ R υ c η: A pile healer with two customers with stripes and alternately arranged scraping bands, in which the aim is to achieve a uniform roving, That is, one pile strip from the upper doffer with one pile strip from the lower doffer is united by placing them next to each other. 1 sheet of drawings.
