PATENT OFFICE.

The subject of the present invention is a feed device for lickerins. The novelty of this feed device is compared to the "devices used up to now" of this kind in that the feed rollers are given an upward and downward movement, whereby, in addition to feeding in the fiber material, pulling and stretching of the same is achieved at the same time. Consequently loosening and cleaning is facilitated and, on the other hand, also has the effect that the fibers in a somewhat straightened state instead of in a more or less confused state the lickerin respectively. be fed to the tear roller. This up and down movement the feed rollers, which remove the fibers from the feed table in the usual way, can be produced in any way. . Namely, you can for mounting the journals of the feed rolls serving cross rails either in an arc shape curved or in straight guides or scenes and so the feed rollers either one arcuate, optionally concentric to the circumference of the Velcro roller, or one to give this tangential movement.

The drawing illustrates these two embodiments of the subject matter of the invention, namely shows:

Fig. Ι an embodiment in side view, in which the feed rolls receive an arcuate movement.

Fig. 2 shows the drive parts of this device in a front view.
Fig. 3 is a top view.
4 and 5 show an embodiment in which the feed rollers receive a straight up and down movement, namely in FIG. 4 in the side view and in FIG. 5 in the front view.

The device consists of the feed rollers provided with scrapers in the usual way I, 2, 3, which remove the fiber material to be cleaned from the feed table 23 and the Feed in the Velcro rollers 7 with Velcro straps 37.

To bring about the upward and downward movement of the feed rollers is now in the embodiment of FIGS. 1 to 3, a frame 5, 6 used, which directly or is rotatably arranged on the shaft 8 of the Velcro roller 7 by means of an attachment. The frame 5, 6 is used to store the by slide or in another way in any distance from each other adjustable feed rollers 1, 2, 3, as well as a brush roller 4. On this frame, one of the guide rollers for the feed table 23 is mounted so that the same on the up and Downward movement of the feed rollers takes part. This movement of the feed rollers and the In the present exemplary embodiment, a table is arranged on the frame 5 Articulated rod 9 mediated, the other end rotatable on a pin passing through the cross head 14 of the Gear 10 is seated, which from a toothed non-circular disc 12 from a and downward movement, with the crosshead 14 between the guides 13 to be led. The movement of the feed rollers is in this embodiment for Axis 8 of the Velcro roller 7 a concentric movement. The one facing the: feed rollers The end of the table 23, which takes part in the upward and downward movement, retains here its distance from the feed rollers.

Claims (2)

In order to promote the pulling out and straightening of the fibers, the feed rollers are expediently of unequal diameter, and it is advisable to give the rollers 2 and 3 next to the table smaller diameters than the feed roller 1. The peripheral speed of the feed rollers, which, as usual, is less than that of the Velcro roller 7, is of course to be set up in such a way that it is sufficient for the uninterrupted supply of the machine. The rotation of the feed rollers, of which the upper one moves in the direction of arrows I, II and the lower 1 moves in the opposite direction IV for the purpose of feeding, can, for example, originate from the sprocket 15 sitting on the axis 8 of the Velcro roller 7 and from there by means of the chain wheel 16, for example, to the feed roller 2 and from here by means of the chain wheels 17, 18 to the feed roller 3. From this the movement is then further transmitted through gear wheels 19, 20 to the feed roller I and, through the intermediary of the chain wheels 22, 21, to the brush roller 4. The table can also receive its movement in the direction of the arrow in FIG. The guide rollers 24 and 31 for the table can be rigidly connected to one another by connecting rods 32, 33 which fit in a known manner by means of threads into a sleeve or block 34 and can be extended and retracted by rotating the sleeve. For the purpose of readjustment, the roller 24 is movably supported in the sliding guides 27, 28 in a known manner (FIG. 3). The bearings 29, 30 accommodating the rollers 31 are fastened by means of bolts to the movable frame 5, 6 carrying the feed rollers. In the embodiment (Figs. 4 and 5), the feed rollers receive a straight, with respect to the circumference .der Kletten roller tangential movement in that they are not mounted on a rotatable on the axis of the latter frame, but on a along the guides 13 frames that can be moved up and down are stored. This frame 41, which is used to support the feed rollers 1, 2, 3 and is guided laterally by the guides 13, is also here rotatable by a link rod 9 connected to the pins of a gear 10 rotated by an out-of-round gear 12. The gear wheel 10 can move up and down by means of a suitable sliding guide. By means of a gear 42 seated on the same axis, a gear 43 seated on the axis of the feed roller 1 is driven at the same time and the rotation of the feed roller τ is effected. The other two feed rollers 2, 3 can be rotated in any way. Here, too, the end of the table which is closest to the feed rollers takes part in the upward and downward movement of the same. In order to be able to set the feed rollers at different distances from one another and from the Velcro roller 7 in the embodiment (FIGS. 4 and 5), the feed rollers 2, 3 are expediently on special articulated rods 39, 40 with their other end resting on the axis of the feed roller 1 stored, which can be adjusted by pins, slots or in any other way at different distances from one another on a rod 38 attached to the cross head 41 and also guided through the rails 13. Since in this embodiment the distance between the feed rollers and the Velcro roller is so small in practice that the contact does not take place along a line of the lateral surfaces, but on a surface, i.e. a contact between these two roller systems takes place over a longer period of time and the peripheral speeds only are low, the fibers are stretched here too, although the feed rollers move up and down in a straight line. The work is made even easier by the large surface of the lower feed roller. The fibers are thereby straightened and exposed to the action of the loosening and cleaning parts of the device for as long as possible, whereby burrs, dirt and other impurities are effectively removed and the fibers are subjected to a pretreatment, so to speak, which later makes carding much easier.
