Description

The present invention relates to the manufacture of mouthpieces and provides a device, the twisting of the mouthpiece in which occurs by the combined action of the swirling tube and the warlide, rotating simultaneously in opposite directions.

FIG. 1 shows a schematic view of the device from the front; FIG. 2 - side view; FIG. 3 is a top view in partial section; Figures 4 through 7 show the positions of the swirl tube and the warp at different points in the action, in section along the line AB in FIG. 2; FIG. 8 - position of the friction clutch at the time of the end of the spinning, twisting, top view.

The device operates as follows: the swirling tube / (figs. 1 - 3), in the internal channel of which there is a pillow 2 and a pusher / 2, has on one side of the bearing / (slot 14, and on the other - friction tooth 9. its rear edge is placed in the bearing / 5, with

gri / b,

than at the end of its gear is fixed and in its front side, located inside the tube /, the warlock 2 has a narrow slot for gripping the mouthpiece.

When the cutting band 1 to the required extent, the strip of mouthpiece tape 3 is brought by the corresponding device (in the drawing

not shown) to the twist tube /, the latter, like the warlock 2, is at rest to their slots coincide in the same plane (Fig. 1 and 4). When the edge of the tape, having passed through the 1pc M tube, enters the narrow slot of the warrior, the tube begins to rotate counterclockwise and at the same time begins its rotation in the opposite direction, and the warrior 9, i.e. clockwise, and thus the mouthpiece is wound on the neck.

The rotation of the swirling tube / takes place with the help of gear 4, moved with fork 5, lever b and cam 7, and the rotation of the swivel 2 with segment 20 and cam / I When the mouthpiece approaches the tube /, the gear is in its initial position and connected Its part 8 of the fist clutch 8, 9 is turned off from the other part 9 associated with the tube / and the segment 20 with its roller 24 rests on the lower lip of the cam 19. Thus the tube / and the warlock 2 are at rest; when the mouthpiece enters the narrow slot of the warrior, gear 4 engages with the fist 9 of the tube 7, and segment 20 begins its movement from left to right and, thus, they both begin to rotate.

The mouthpiece and tubing are pushed out by the pusher / 2 using the lever 22 and the cam 23.

The subject matter of the invention.

The device for tightening the mouthpieces in the sleeve-mouthplate machines, characterized by the use of the warlock 2 and the tube enclosing it /,

in rotating percussion mouthpieces in rotation in opposite directions, and to stop the tube 7 in the intervals between the twistings - a release coupling 8, 9 is included in its drive.
