Abstract

The connector consists of a rotary striker arm (3) with a hammer (4) on one end and a cam (37) on the other. When a paper strip (2) is beginning to run out, a power cylinder (51) actuates a roller (53) which interacts with the cam (37) and brings the surface of the hammer into contact with the paper. The mechanism also incorporates front and rear cutters which cut off the free ends of the paper strips before and after the joint.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for connecting strips of compliant material, in particular paper webs used in the tobacco industry to produce cigarette wrappers of tobacco or cigarette filters, and can be used to perform butt joints of other similar materials, e.g., smooth, creped, double-sided glazed, high-gloss and lacquered paper, paper or other materials in combination with aluminum foils, synthetic foils, eg cellophane or polypropylene, non-woven materials or thin metal foils, eg aluminum. Said materials may be used as thin coating layers of some part of the cigarette or its filter. The belts can be printed on one or both surfaces.

Present to date .. \ t

The devices are known in the art and described in several documents. EP-A-O-318,427 discloses sufficiently a method and apparatus for attaching cigarette paper strips, including a work step that precedes the replacement of discs, preparation of a solid disc, and introduction of the top of a full roll coil to the device. In principle, the device performs the connection of the strips after the unwinding of the unwinding and it is therefore necessary to interrupt the operation of the production machine or to have a secondary device 5 provided by a sufficient length of the reserve web for filling the "C" of the production. · &Quot; cigarettes .- · after, -time. watering-saving.

· - - /: /, '·''/·' ^ Xr '-j / S stop and resume working speed, it is necessary to have a backup of a sufficiently long strip on the secondary device, making the whole file more complex and spatially larger. A compromise solution to these disadvantages of reducing machine speed = < shortening the length

spare belt reduces productivity, which is not negligible. Although the method and apparatus described in the application EP-A-0.475.886 makes it possible to connect the webs of paper during unwinding, the device is only suitable for connecting strips of paper intended for cuffs or cigarette filters. The device is provided with two rollers inserted into the grooves so as to connect the end tabs of the paper strips. This device is only suitable for some types of paper. Other devices perform φ bonding of both belt ends with adhesive tape, and the disadvantage of this method is the need for operator presence. ^ Connecting the paper strips is related to the cutting of paper pieces that protrude on both sides of their connection. The above devices are provided with a shearing mechanism that is independent of the device to be connected, which requires complex synchronization, at least with respect to the speed of both operations. EP-AO.331.634 solves the method and apparatus for opening a solid disc and for preparing the edge i. EP-A-0.509.958 discloses a method and apparatus for moving coils or discs during unwinding. Both. The apparatus may suitably be used with the apparatus described in this application. ... . ". .., v ...; .

Fig. 3 illustrates a punching arm 3 which, when rotated, strikes the bumper surface 37A of the cam 32 onto the cylinder 53. The impact has caused the knob arm 3 to be moved with the tap head 4 and thus to force the upper surface of the paper web 24 to the lower surface 41. Stalk heads. The impact of the cam on the roller 33 is not punctual, and the wear of the cam during the contact of the cam with the roller at one-turn of the hammer arm. The 37R of the cam 32 is large enough to move the hammer arm 3 close to both of the paper webs 2 and 21 and the bottom surface 41 of the tap head on both of the paper webs and has compressed them strongly onto the support roller surface 6.

The overpressure thus caused will further increase the pressure of the lower surface 41 on the paper web and on the support roll surface. Between surfaces 41 and 40, a pressure of the order of 200 kg is formed at the time of contact on a paper width of the order of 50 mm. This pressure is sometimes increased by scoring the surface of the bottom surface 41 and firmly bonding the two sheets of paper, similar to a cold weld. The lower surfaces 41 arranged in a plurality of fields 40 and 42 make it possible to reduce the pressure on the large-width belts.

Place the support cylinder L · 12 «on the hZi shaft. in a resilient support that attenuates said position difference from 12 mm.

In addition to the aforementioned adjustment, the device according to the invention does not require alignment with the cutting mechanism which is controlled by the movement of the adhesive head 4 ·

The paper belt connection device is described herein; .the position at which the paper strips unfold in an approximately horizontal plane. Running the machine would be the same if the paper strips were unwound approximately in a vertical plane. The stripping angle depends on. positioning the machine and can therefore be any.

Mechanical components of the apparatus, in particular cylinder 52i cam 22.1 for adhesive head 4; and the support roller &amp; as well as the parts that carry them undergo considerable mechanical stress and will therefore be made of durable materials. '? »' * '

Due to the severe impact of the impact head 4 on the two bands to be joined and the possibility of varying the surface arrangement of the bottom surface 41 and the choice of impact force by controlling the position of the roller 53 against the cams according to the invention, the different types of belts can be joined from Thin and brittle, PP thin metal strips, for example aluminum, can also be used to bond the stripes of synthetic materials and strips made of aluminum. ~ -. v '-,; In particular, the device according to the invention performs a laminated material. . bonding, belts of all kinds of paper and other materials used in the tobacco industry, including relatively wide belts.

Said front cutting mechanism (8) may be maintained by the tongue (85) in a rest position in which the knife (83) is spaced from the belt (21) or in the working position in which the support surfaces (84) of the lever (80) activated by the two contact surfaces (62) of the support roll (21) to move the knife (83), which strip (21) of flexible material overlaps. ,. r Equipment for connecting belts according to point. 6 or 7, characterized in that the rear cutting mechanism (9) is provided with at least one lever ("which rotates on the pin (91) parallel to the axis of rotation of the support roll (6) and is located behind said cylinder on the same wall (13) The blade (93) is inserted in the part of said levers and its length is at least equal to that of the strip (2). 9) can be maintained with the tongue (96) in a rest position in which the nose (93) is spaced from the belt (2) or in the working position in which the edge (94) of said lever (90) is activated by a cylindrical projection ( 95) on the side of the hammer head (4) to displace the knife (93), which strip the flexible material (2) at the point 7 or 8, that the knife (83) of the front end The rear cutting belts (2, 21) are: at the belt connection device according to the invention. of the cutting mechanism (3) and the knife (93) in the mechanism are activated to overcome the extended position of the impact head (4). characterized in that it is provided with control means (7) with a control unit (70) which can find that one of the disks (20) from which the flexible material strip (2) is unwound is almost empty may instruct to start rotating the spreader arm (3) and adjusting its rotation speed so that the circumferential velocity of the bottom surface (41) of the knock-on head < 4 > (5Γ) the "arm" reaches the first determined angular position and terminates the operation of said jack after the connection has been made, and then stops the rotation of the hammer arm at the second defined angles position.
