As can be seen from Fig. 3, the foot plate 13 is connected to a downwardly protruding hollow stub shaft 15 which is rotatably mounted in a central bearing 16 arranged below the floor level. The jug 12 is in frictional connection with the foot plate 13, its axis coinciding with the axis of rotation of the foot plate 13. The foot plate 13 is driven by a friction roller 17 which engages the underside of the foot plate 13 while the rotary movement of the foot plate 13 onto the jug

12 is transmitted through the frictional connection between the lower part of the jug 12 and the foot plate 13.

Inside the hollow stub axle 15 of the foot plate

13 is an upright mandrel 18 with a conical head piece 19 axially displaceable, which is connected to an arm 20 of an angle lever 21 , the other arm 22 of which is coupled to the associated end of a piston rod 23 of a pneumatic working cylinder 24, which in turn is below floor level is arranged. The arrangement is made in such a way that the mandrel is during the deposition of the tape

The base plate 13 protrudes and engages in a central opening 26 in the lower part of the jug 12 , while the mandrel 18 is lowered into a position below the base plate 13 when the working cylinder 24 is actuated.

As can be seen from Figure 2, 13 guide rails 27 to 30 are provided in the floor in the area of the foot plate, the cans 121, 122 along a path

HSSSSISS each provided with a reinforcing edge 39 which is arranged in such a way that it engages with the stop finger 36 or 37 cooperates and that the reinforcement edges 39 of adjacent cans abut one another, when the cans are pushed together.

During operation, the sliver is deposited from the head plate into the can 12 arranged in the center of the foot plate 13 and set in rotation by the latter. During this time the mandrel 18 is in the position shown in FIG. 3 held the position illustrated in which it protrudes over the foot plate 13, while the piston rod 35 of the working cylinder 34 is in the fully retracted position shown in FIG. 1 is shown, the two stop fingers 36,37 being some distance behind the empty cans 121,122 in the first and second storage positions.

As soon as the jug standing on the foot plate 13 is filled, a length measuring device assigned to the head plate emits a signal that is used to stop the head plate and to actuate a valve which supplies compressed air to the working cylinder 24 which actuates the mandrel 18, which then drives the mandrel 18 withdraws. At the same time, the mandrel 18 actuates a further valve which allows compressed air to flow to the working cylinder 34 of the can feed device, so that the piston rod 35 is advanced over its entire stroke, whereby the stop fingers 36, 37 with the cans 121 in the first and second storage positions , 122 come into engagement and advance them at the same time. The empty can 121, which is in the first storage position, strikes against the full can 12 and pushes it down from the foot plate 13. The size of the stroke of the working cylinder 34 of the Kanr.envorsohubvorrichtung is selected such that the full

Jug 12 is transferred from the empty jug 121 into a position that is a certain distance away from the foot plate 1.1, with the empty jug 121 still in contact with the full jug 12 on the foot plate 13 taking a position beyond the for the sliver deposit to be assumed middle position. Has the piston rod 35 its

executed entire working stroke, the working cylinder 34 is acted upon in the opposite direction with compressed air, see above that the first stop finger 36 against the action of a spring and down on the lower part of the first Is withdrawn by sliding along the supply position can 122. Another, im individual empty jug, not shown, either by hand or by a conveyor on the Floor 14 introduced between guide rails 29, 30, the second stop finger 37 against the action of a spring is pivoted to transfer the further empty can into the second To allow stockpiling. When the piston rod 35 has completed its backward stroke, it becomes the mandrel 18 actuating working cylinder 24 is acted upon in the opposite direction with compressed air, whereby the mandrel 18, as in F i g. 4 illustrates, advanced through the opening of the foot plate 13 and with the lower part of the empty Can 121 is engaged. The arrangement is made such that the conical head of the Domes 18 on the edge of the opening 26 in the lower part of the jug 21 comes to rest and further Advance of the dome 18 moves the jug 121 on the foot plate 13 so far that it is in a central one Position is withdrawn in which it is ready to receive the sliver coming from the head plate

The conical mandrel 18 centers the can 121 standing on the foot plate 13 (FIG. 3).

The full can 12 can be pushed onto a trolley in the form of a platform 41 (FIG. 1), which with Pairs of rollers 42, 43 is provided. For this purpose, the floor 14 is on the discharge side of the foot plate 13 provided with two spaced apart ramps 44, 45 which are below the floor level extend and on which the carriage 40 runs with the rollers 42, 43 to its platform 41 on the To bring floor level. The arrangement is made such that the jug 12 when it is moved from the foot plate 13 on the platform 41 of the lowered

Car 40 is moved, the ramps 44,45 having such a slope that a movement of the Car 40 is prevented when the full can 12 is pushed onto the platform 41. Below the Floor level is a hand-controlled pneumatic

shear thrust piston motor 46 is arranged, which when actuated on one of the carriage 40 below the Platform 41 acts above the stop and the carriage 40 with its rollers 42, 43 the ramps 44, 45 up and onto the floor 14, where he is then from
