leather (not shown) or biased under the influence of gravity in their inclined position.

A part of the welding device 2 which forms a drum 13 is mounted opposite and below the front end of the slideways 6. The drum 13 sits on a horizontal shaft 14 and contains (see! FIGS. 3 and 4) a pair of spaced-apart, circular disks 15 ₅ which are mounted coaxially on the shaft 14. Four sets of studs 16 sit in sets of holes 1? » which are arranged in each disc 15 in an angular position. A conical hub 18 is also mounted on the shaft 14 outside the outer surface of each disk 15. In addition, the drum 13 forms four frame elements, each of which consists of a pair of spaced-apart, substantially 90 ° segments forming end plates 19, which are connected to one another at their periphery by four equally spaced rods 20, one in each of the rods 20 Cutting blade 21 is inserted, which protrudes from the rod surface. The outer edges of the end plates 19 between the rods 20 also run straight, so that with the aid of the plates and rods of each frame element three flat rectangular openings are formed. At the foot of each end plate 19 an arched surface 22 is attached in order to reach in this way from the plate outer surface at a slight angle to the normal of the plate plane. Each frame element is mounted on the discs 15, with the end plates 19 on the outer

side of the washers 15 and the studs 16 pass through radial slots 43 in the end plates 19. In this position the arched flanges 22 form together a frustoconical space at each end of the drum and rest on the had 18, which is keyed in its interior on a bushing 25, which in turn has a thread is mounted on the shaft 14.

The two sockets 23 are against mutual rotation wedged together, but slidable relative to each other. The two sockets are threaded from opposite Provided sense, so that when they are rotated by rotating a wheel 24 on one of the shafts, the hubs 18 as a function be pulled inward or pushed outward by the direction of rotation of the wheel 24 · Move in this way the four frame elements move inwards or outwards, the inward movement being effected by springs 25 will. Thus, the peripheral speed of the drum 13 can be adjusted by changing the effective diameter of the drum can be changed while the drum is driven at constant speed by means of a wheel 26 which has a driving pin 27 brägb, which passes through one of the slots in one of the end plates 19 and is connected to one of the disks 15 in Engagement is.

the loading device 3 facing away from the side is closer than the top of the drum 13. Above the drum is a Pressure roller 29 is mounted, which is also part of the welding device 2 and includes a cylindrical metal core 30 and a cylindrical metal tube 3I, which is fitted to the metal core 30. The outer surface of the tube is the contact surface of the pressure roller and consists of a series of protruding ones arranged around the roller Rectangular frame 32, the size and shape of which is adapted to the edges of the openings of the drum I3. Every face of the core 30 forms three bores 33 which run parallel to the core axis and are the same radial distance from the Eernach.se exhibit. Three elongated cylindrical heating elements (not shown) are replaceable in the bores housed at each end of the core 30. The heating elements are attached to a (not shown) circular disc, which rests on the corresponding face and on its outer surface a series of concentric slip rings (also not shown) carries. With the help of brushes resting on the slip rings, the heating elements powered. The pressure roller described is arranged in such a way that it presses against the upper side of the rotary drum 13 during operation, as shown in FIG.

direction 35 contains the film via a device for printing of the strip with a date or other information into the gap between the drum and the printing roller. The register device 35 comprises a photocell 36 and a light source 37 on opposite sides the transport path of the film of the roll 3 ^ - are arranged. The strip is periodically opaque with, for example colored areas which pass between the photocell 36 and the light source 37. One Sliding device 38 (only shown schematically) is mounted on an endless chain, the angular position of which is relative to the Cutting blades of the drum 13 is adjustable so that the Device 38 is drawn over the film lying on top of one of the cutting blades, the container through a chevron-like movement can be separated from each other.

The removal device 4 contains an inclined conveyor 39 » which is arranged below the device 38 for the removal of the finished articles from the device.

In operation, the chain conveyor 7 is a row of open confectionery containing plastic container supplied and thereby pushed along on the slideways 6. If the foremost Container reached beyond the range of the conveyor 7, its movement is taken over by the loading table 8, the reciprocates synchronously with the movement of the conveyor 7. The plate 11, which is in its inclined position on the

1 09887/1124

Loading table 8 is pre-tensioned, pushes the foremost container from behind under the influence of the forward movement of the piston rod 9 until it is easily held between the plate and the continuously rotating drum 13. As the drum 13 rotates, the plate 11 is under the influence of the spring pressure of the spring-loaded carrier 41 until the container falls into one of the openings in the drum 13. The piston rod 9 is then withdrawn so that, as the table 8 moves back, it slides under the next container, the weight of the container being sufficient to move the plate 11 at the end of the table 8 into its horizontal position. When the table 8 has completely passed the container, the plate moves back to its inclined position under the action of gravity or a spring. The forward movement of the table causes an impact on the container through the inclined plate towards the drum and into that of the previously filled adjacent opening, the edge of the container coming to rest on the edge of the opening. The table then moves back for the next loading process. The containers carried by the drum 13 then pass into the gap between the drum 13 and the pressure roller 29. Here the film lies on the opening of the container and the pressure roller, which is heated, welds or glues the film to the edge of the container . The further rotation of the drum brings each container in sequence to the sliding device 38, which is synchronized and moves across the cutting edge.

blade 21 to move behind the container in question in order to remove the applied plastic film from the next Separate film length. At this point the bottom of the container has the determined curved ejector plate 28 in the Drum 13 touches the process of ejecting the sealed Starts the container from the drum »If the plastic film is repeatedly printed, it may be necessary to to bring the container and the printed plastic film exactly into alignment so that the imprint is central on each Container appears. In such a case, only a small amount of relative movement is usually required. This can be done by Use of a clutch or brake and a motor can be achieved that drives the wheel 24 to the effective diameter the drum 13 and thus the peripheral speed of the container on the drum changes, so that a precise grid the container and the imprint is effected on the film.

The register device 33 is used to control the operation of clutch, brake or motor when driving the bath 24 by changing the positions of the opaque areas of the photocell 36 are detected and these signals are related to the relative position of the drum 13.
