^ o transported in the base part 19. The base part can be movable or comprise a movable component in order to make the interior of the housing 1b accessible, in particular for purposes of non-disclosure. In order to drive the two belts, the two front rollers 22 and 24 can be connected to one another by pinions 29, and the shaft 30 carrying the roller 22 can be driven via intermeshing Izalmr ad er 51, a vertical shaft 32 and an upper pinion 33. which cooperates with a ring gear 34 supported by the gear wheel 9. Further Gurtreinigungsmittel may be provided which are disposed g so that they are pressed against the belts. 20 and 21

Both the first organ A and the second organ B must are driven so that the second member B rotates about its own axis 14 at a higher speed than it rotates around the first axis 15 together with the first organ A. To make this possible, the vertical drive shaft 7 is provided at its upper end with a pinion 54 with an upper gear 3-5 meshes, by means of which a lower Pinion 36 is driven, which meshes with the gear 9 in order to drive the first member A at the desired low speed.

Sig. 1 is the double sun gear 39> 4-O.in his Correct location shown while it is in Pig. 2 from iründen ■ - who obviously takes a different position. Thus, from a common drive shaft accommodated in the column part 6 7 from the two organs or sub-units A and B in a simple ./eise driven via gears and simultaneously a driving force is transmitted to the belts 20 and 21.

As described above, the stretch tape feed tube 27 is straight and inclined so that the stretch tape can move freely through the tube ; however, it would also be possible to provide a curved or coiled feed tube. The inlet end of the tube 27 protrudes into the inlet 42 of the hollow Uabteils ö of the first organ A, it extends through the v / and of the Uabteil, and its outlet opening at the lower end is immediately above the passage point of the front rollers 22 and 24 as well as in the proximity of the already mentioned second axis 14 is arranged. The upstream% mechanism described are two drivable calender rolls _r assigned to the 43 directly above the inlet. end of the feed pipe 27 are rotatably mounted in a stationary manner.

The calender rolls 43 are from the drive for the already driven device described; for this purpose a second vertical shaft 44 is used by the mentioned gear 37 driven off by a pinion 45. This second much drives a horizontal shaft 46 over in an upper (leliäuse 4b arranged bevel gears 47. The horizontal shaft 46

The cover 1 comprises according to Pig. 2 a stationary one lower j & ing and an actual cover, cut in half is divided, which are rotatably mounted on a built in the upper bridge part 4 bolt i? 0.

In the case of smaller constructions, the bridge part 4 shorten to half a cross member, that of the column part 6 protrudes from inside. Alternatively, the support member can be designed as an arm star.

It can thus be seen that the invention is suitable for eliminating a difficulty that arises when inserting Stretching belts in cans results, because the invention provides a considerably low f compared to known devices Geren cost manufacturable device before working with a planetary motion. With the so far known inserting devices operating with a planetary motion use large, circumferentially extending bearings, which have to be designed as roller bearings when inserting stretch belts at high speed. Ball and . Large diameter roller bearings are very expensive, and In order to reduce costs and avoid delays in the delivery of spare parts, we have special stocks of large

In the device according to the invention, however, the dimensions of the bearings to be used are completely independent of both the dimensions of the cans and the eccentricity of the planetary motion. The dimensions of the bearings are based only on the normal mechanical criteria, such as the load, structural aspects and the like.

furthermore, the bearings of the owls over which the belts to feed the stretch strip, all of them on a rail door arranged so that after the trapdoor is opened, the whole Lrurtaggregat is accessible for cleaning. Such In the case of the construction described here, a skeletal support element in the form of a bridge part requires an arrangement Transverse arm or an arm star not to be provided, because when the cover 1 is removed, the ijeile of the reading device easily accessible.
