element 5, the separation of the leaves coincides with the axis of the plant. The device has a drive mechanism 10 for rotating the sleeve, through which an elastic copier 11 (rubber tape) passes, which repeats the shape of the contour of circuit 1 by means of elements 12-15. The mechanism for forming cells 16 is attached to the leaf separator elements 5, along the line of movement of which the stops 17 and 18 are located. A output disk 19 is attached to the driven sprocket 3. At the beginning of the device there is a winding disk 20. The device is closed by a casing 21.

The leaf separator 5 consists of a sleeve 22, into the guide surface of which an axially located sleeve 23 enters, which is rotatably mounted. Sleeve

22 is cut into two parts - half-sleeves 24 and 25, pivotally connected by means of brackets 26 and 27 and a roller 28. The semi-sleeve 24 is connected to the bracket 6. The sleeve 23 is cut into

two half bushes 29 and 30 pivotally connected by means of a spring plate 31 with screws 32. To bushings 22 and

23 are connected axially located collet knives 33 and 34, cut in one place into two parts with the ability to rotate one relative

to the other. I

The cell formation mechanism 16 consists of a semi-sleeve connected

24 of the bracket 35, which is attached to the boss 36 and the stop 37. To the half-sleeve 25 is connected the bracket 38, the hole of which is coaxial with the hole of the bracket 35 in the closed position

semi-sleeves 29 and 30. The coaxially arranged openings of the semi-sleeves 20 and 30 include a pusher 39 with a conical inlet chamfer 40. In the existing hole of the bracket 35, a lever 41 is mounted, on which a gear wheel 42 fixed in rack with the pusher 39 is fixed.

The hub rotation drive mechanism 10 consists of a bracket 43 connected to a half-sleeve 25, on which a freely rotating sprocket 44 is mounted and a roller 45 mounted on its axis. The sprocket 44 engages with perforations in the hub 23. On the bracket 43 there is a freely rotating driving roller 46 and a roller 47 paired with it. The rollers 45 and 47 are connected by a rubber band 48. A boss 49 is attached to the bracket 43. The lugs 36 and 49 are connected by an extension spring 50. A bracket 51 is attached to the bracket 6 with freely rotating rollers 52 and 53 which touch the spring of the copier 11. The stop 18 consists of a spring plate 54 and a stop 55.

The device works as follows.

When the driving sprocket 2 rotates, the chain 1 by means of the brackets 6 and 7, the plate 8 and the Elastic element 9 moves the leaf separator 5. The half-sleeves 24, 25, 29 and 30 are in the open state. At this moment, the axis of the roller 28 coincides with the cut of the sleeve 23. The axially located knives 33 and 34 are opened. The drive roller 46 does not touch the elastic copier 11 (Figs. 5 and 6). The horizontal component of the speed of movement of the chain of the device for separating the leaves and the center of the element 5 of the separation of leaves is equal to the speed of movement of the plant. The linear speed of the center of the groove of the winding disc 20 is equal to the speed of movement (Fig. 1).

The planting disk 20, rotating, slits the plant into the leaf separator 5 (Fig. 2). At the moment when the plant is inserted into the leaf separating element 5, the stop 17 puts pressure on the lever 41 (FIG. 5 and 6), turns the gear wheel 42 (FIG. 7), which through a pinion gear (FIG. 9) moves the pusher 39 ( Fig. 5 and 6).

39 presses on the bracket 38 and rotates it relative to the axis of the roller 28, overcoming the tensile force of the spring 49 to the coaxial position of the holes of the brackets 35 and 38. The pusher 39 of the conical lead-in chamfer 40 enters the hole of the bracket 38 by means of a pinch of the half-sleeve 24 and 25, 29 and 30 closes.

In the closed state of the sleeves 22

and 23, the collet knives 33 and 34 are rounded in cross section and mounted so that the sleeve 23 is able to rotate in the guide surface of the sleeve 22 (Fig. 8). Simultaneously with the half sleeve 25, a bracket 43 attached to it rotates, which drives the drive roller 46 in contact with the elastic copier 11. The roller 46 rotates, rotates the roller 45 by means of a rubber braid 48. The roller 45 rotates, transmits the rotation of the sprocket 44, which rotates the sleeve 23 with the collet knife 33, the segmental teeth of which, together with the stationary segment teeth of the knife 34, of the sleeve 34 accept the properties of the cutting and counter-clamping elements. Due to the slotted collet knives cover the plant depending on its diameter (Fig. 5 and 6), due to the elasticity of the copier 11 and the rollers 52 and 53, the sleeve 23 can rotate when the device for separating the leaves from the row axis deviates. The leaf separating element 5 deviates from the row due to the elasticity of the elastic element 9. The leaf stalk, between the segment teeth of the rotating 33 and the fixed 34 collet knives, is cut off (Fig. 3 and 4).

The separation process; tobacco tobacco g occurs around the entire circumference of the stem. At the same time, due to the inclination of the chain 1, the moving element 5 of the leaf separator has a vertical velocity component and, therefore, moves along the stem to produce leaf cleavages. The horizontal component of the speed of the device for separating leaves is equal to the speed of movement, and therefore, the relative speed of the device for separating leaves against the plant is zero. At the end of the leaf separation process, the stop 18 puts pressure on the pusher 39, which extends

before the end of the groove of the pusher touches the stop 37, the spring plate 54 deforms and removes the stop 55 out of contact with the pusher 39. Semi-bushes 24 and 25 have a revealing effect on the semi-bushes 29 and 30. When the roller axis coincides with the section of the sleeve 23 on the side of the spring plate 31 under the action of the stretch spring 50, the half-sleeves 24 and 25, 29 and 30, the collet knives 33 and 34 are opened (Fig. 11). The device for separating the leaves, moving along an arc of a circle, which is set by chain 1, which bends the driven sprocket 3, moves away from a row of plants. The output disc 19 removes the plant with its slots from the element 5 of the leaf separator (Fig. 1).
