Description

The main copyright certificate Kg 22548 describes a machine for sewing tobacco leaves, consisting of an ordinary sewing machine, equipped with an endless leaf feeder with pleats sewn on it, a cord to form transverse grooves for placing the cuttings of leaves and Gall pressure chains, which serve pressing the cuttings of leaves to the cord, unwinding from the coil.

In the proposed machine for stitching tobacco leaves, an exhaust mechanism is used, consisting of two alternately operating drums, rotated with weights and wrapped with cables with clips at the ends for alternating gripping of the braid on which the leaves are sewn.

In FIG. 1 shows a machine in longitudinal section; FIG. 2 - the same, from above; FIG. 3, 4, 5 - separate parts of the machine.

The tobacco leaf sewing machine consists of a table /, under which, at the end on the left, is sprocket 2, and in the middle is a leading sprocket 3 for moving the chain with the bars 4 to the right along the longitudinal cut 5 of the table /.

The lower level of the slats 4 is at table level. House with an asterisk 3

(297)

there is a roller 6 with a cotton braid 7 wound on it, which is fed to the surface of the table /, through the opening 8.

At the right end of the table there are two pairs of drums 9 and 0 of different diameters on the same fixed axis. Each pair of 9n fO drums are merged together. Cables // and / 2 are so secured on the drums that when the load 75 is lowered down and, consequently, when the cable is unwound / 2, the drum 9 winds a cable // at the end of which a hinged rhomboidal clip / 4 is attached. Under the reverse action, i.e., when the cable is tensioned, the // drum 70 begins to wind the cable / 2 onto itself and lift the load J3 up.

A sewing machine / 5 is attached to the side of the table. Her needle / b comes over the tape 7 lifted upwards. Right and left needles J6 (Fig. 3) there are two rollers / 7, of which one is driven with a soft rubber band J8 stretched between them. The movement of this tape must exactly match the speed and direction of movement of the chain with the strips 4 and the machine.

First, lay out tobacco leaves / P by cuttings in the slots formed by the slats 4. These slats are from movement

the chains on which they are attached, remove the leaves 19 to the sewing machine 75. Unwind the string 7, slip the end of it under the belt 18, onto the other side of the machine / 5, then this end is clamped with the clamp 14, which, under the influence of the load 13, will begin to pull the string 7 to the right. Leaf 19, supplied by the chain after meeting with the tape 7, passes further below. The rubber pressure tape 18 is already directly attached to the tape 7, touching it with its own cuttings, and “Ashina 15, work, sews these cuttings to the tape 7. When the tape 7 thus goes, with leaves 19 already sewn to it, it will reach the drum 9, and the load 13 will reach to the stop, stir, load the load 13 up for the cable //, then “it is necessary to hook the second clip 14 of the second pair of drums P and 7 (for 7).

When it leaves the machine 15 and next to this clip, it is necessary to cut the tape 7, and then remove the first clip 14 at the drum 9. After that, the tape with the leaves is removed.

The conventional machine foot is replaced for the above-described new job (Fig. 5), in which the grip angle 20 is larger than normal and there is a hinge 2 /.

The subject matter of the invention.

The modification of the machine according to the author's certificate No. 22548, characterized by the use of an exhaust mechanism consisting of two drums 9, 9, rotated by weights 13, 13 and wrapped with cables 77 with clamps 7 at the ends dp of alternate gripping of the band to which the leaves are sewn.
