` COILER FOR CARDS USED IN TEXTILE I-NDUSTRY 2 Sheets-Sheet@ Filed June l5, 1965 ATTORNEY s United States Patent O 3,372,437 COILER FOR CARDS USED IN TEXTILE INDUSTRY Igor Nikolaevich Iliin and Pavel Ivanovich Aristov,

Filed June 1S, 1965, Ser. No. 464,012 1 Claim. (Cl. 19159) The invention relates to cards used in textile industry land more particularly to sliver coilers for these machines.

In the textile industry, coilers are known which include a can provided with an inlet and a mechanism for coiling the sliver into the can arranged above can. However a coiler of this type does not allow cards to be used in conjunction with other machines operably related to the further processing of the sliver. In addition, with these coilers, it is not possible to form a stock of sliver at each card.

Attempts have been made to overcome the above mentioned disadvantages but none of these prior proposals have been successful.

Applicants have found that such disadvantages can be overcome by the employment of a coiler comprising a can having a sliver inlet opening in the bottom thereof, a mechanism for laying a sliver in the can mounted on a base beneath the can adjacent to the inlet opening, and a device for feeding positively in an upward direction a sliver mounted in the coiler.

The object of this invention is to provide means ensuring operation of the card in conjunction with other machines operably related to the further processing of sliver.

An important object of the invention is also to insure a sliver stock at the card.

Further objects and advantages of the invention will become more readily apparent to persons skilled in the art from the following detailed description and annexed drawings and in which drawings;

FIGURE l'is a front view partly in elevation and partly in cross section of the coiler embodying the present invention,

FIGURE 2 is a top plan View of FIGURE 1,

FIGURE 3 is a View in side elevation of the coiler shown in FIGURE 1,

FIGURE 4 is a diagramamtic view in elevation showing the coiling of the sliver inthe can, and

FIGURE 5 is a view looking in the direction of the arrow A shown in FIGURE 4.

The coiler consists of a can 1 (FIG. 1) provided with a sliver inlet at the bottom thereof. A turntable 2 is mounted beneath the can and provided with an eccentricallly located opening 3 for the passage of a sliver and intended for coiling the sliver in the can 1. A trumpet 4 and positively rotated rolls 5 are mounted on the turntable 2 and function for the positive feed of the sliver in an upward direction. In order to permit the oper-ation of cards in conjunction with other machines operably related to the sliver processing such as for instance drawing frames, the can 1 is provided in its upper part with a sliver outlet. The turntable 2 is rotated through a worm and worm wheel 6-7 mounted on shaft 8 of card condensing rolls 9, and through -gear 10 meshing with the toothed periphery of the turntable 2.

For coiling the sliver according to a desired pattern,

for instance a hypocycloid, a reciprocating movement is imparted to the can 1 by means of crank mechanism 11-12 driven by the shaft 8 through bevel gears 13-14. More particularly, the can has a reciprocating movement along a circumference that is to say by a movement along a circumference during which the line connecting two points of the can always remains parallel to the line connecting the points in any position of the mechanism. The can 1 is arranged relative to the turntable 2 with an eccentricity as denoted at a. The rolls 5 are driven by bevel gears 15, 16, and the bevel gear 16 is mounted in a housing 17 provided with an axial opening 18 for the passage of a sliver 19.

To prevent displacement of sliver coils relative to the can 1, the can is provided with a sliver braking device 20. The coiling of sliver is effected as follows:

The sliver 19 comes from the condensing rolls 9, moves about guide bars 21, 22 (FIG. 4), Passes through the opening 18 in the gear 16, through trumpet 4 and is grasped by the rolls 5 which feed the sliver in an upward direction. The sliver is passed through the opening 3 in the turntable 2 which, being set in rotation, coils the sliver into the can 1 in shape of a hypocycloid. Next, the sliver is removed from the can 1 and forwarded to other machines for subsequent processing.

Thus the present invention elects coiling of the sliver into the can from the bottom thereof and provides for the accumulation of a sliver stock at the card whereby the cards may be used in conjunction with other machines for sliver processing.

The invention is not to be confined to any strict conformity to the showings in the drawings but changes or modifications may be made therein so long as such changes or modications make no material departure from the spirit and scope of the appended claim.

What is claimed is:

1. A coiler for cards and sliver machines employed in the textile industry, comprising a can adapted to execute a reciprocating movement along a circumference, Said can having a sliver inlet opening in the lower portion thereof, means operably related to the can for preventing displacement of sliver coils relative to the can, a turntable beneath the can with the can being disposed eccentrically respecting the turntable, means for coiling the sliver in the can mounted on the turntable in close proximity to the sliver inlet opening, means mounted in said coiling means for positively feeding the sliver in an upward direction into the can through the sliver inlet, a driven shaft, a rst drive connection between the driven shaft and the turntable for imparting rotary movement to the turntable, a crank mechanism operably connected to the can, and a second drive connection between the driven shaft and the crank mechanism, for imparting a reciprocating movement to the can.
