Fig. 2 shows a device with four operator stations, i. E. the operator station B5 of FIG. 1 with associated Guide rail 29 is omitted. The guide rails 16 and 21 are essentially U-shaped, the short legs facing outwards, d. H. face forward and backward. On these guide rails are the Carriages guided displaceably, only the carriages 15 and 20 can be seen in Fig. 2, via rollers 15 'or 15 ″, which run along the inside of the short legs of the guide rails 16 and 21, can be used by the carriages be moved. To secure against falling out, the short legs pointing outwards can each be added have short legs pointing towards one another, whereby the rollers or wheels 15 'and 15 "in the axial direction are secured. At the lower end of the carriages 15 and 20, brackets 35 and 34, respectively, of known design are attached, in which items of laundry can be jammed. The carriages are moved by pulling members 32 and 33, as will be described in more detail in connection with the following figures. One trained as a belt conveyor Feed conveyor 36 is stretched, guided and driven via deflection or drive rollers 37 and 38. in the In the input area of the feed conveyor 36, a pressure roller 39 is also provided, by means of which the laundry items held on the feed conveyor 36 and conveyed in the direction of arrow 40. Below the feed conveyor a smoothing device is also provided, which here consists of a device working with negative pressure 41 with tilatt brushing edge and smooth brush brushes 42.

3 and 4 show the clamp conveyor of the, Operator station B1.

The front carriage 14 with the associated clamp 35 'is J ₁ firmly connected to the pulling element 32, which is guided in the form of an S belt by deflection rollers 45 and 46, at least one of which is drivable. The carriage 14 is here on the underside of the Zugorganes 32 attached. The carriage 15 with clamp 35, on the other hand, is freely displaceable with respect to the pulling element 32 - within certain limits. Two stops 47 and 48 are now firmly attached to the top of the pulling element, with a fixed distance from one another in the direction of movement of the pulling element, which is the distance between the center line 13 in single-lane operation and one

Center line 49 of the partial web 11 corresponds. ■;

As can be seen from FIG. 4, the stops 47 and 48 are offset from one another in the transverse direction of the pulling element 32 by a distance 53 denoted by X, so that the stop 47 lies on a stop track 51 (S1) and the stop 48 lies on a stop track 52 (SA).

As will be explained further below in connection with FIGS. 8 and 9, the carriage 15 has one optionally with the stops 47 or 48 cooperating stop, so that the following mode of operation results. Assume that the stop on the carriage 15 is set in such a way that it interacts with the stop 47. Between the two A laundry item is clamped in clamps 35 and 35 '. The pulling element 32 then moves first in response to a corresponding command the carriage 14 with the bracket 35 ', while the carriage 15 with the bracket 35 and the rear end of the Item of laundry is still standing still. This movement first removes the slack and the item of laundry tightened to some extent. The rear carriage 15 is then dragged and moved over the item of laundry in Fig. 3 also to the right. By moving

of the front carriage 14, the stop 47 was also moved, namely to the left in Fig * 3 in the direction of the rear carriage 15, in the course of the movement described the stop 47 now strikes the stop on the carriage 15. This takes place exactly when the item of laundry - Regardless of its length - is centered with respect to the center line 49 of the partial web 11. The drive member 32 i is then set, and the handover of the item of laundry takes place on the feed conveyor, as described in connection with FIG.

If, on the other hand, the stop on the rear carriage 15 is set so that it coincides with the stop 48 of the stop track 52 cooperates (single-lane operation), the item of laundry is opposite the center line 13 in a similar manner to 15th

centered as described above.

In the embodiment of FIGS. 3 and 4 is sufficient for Switching from one to two-lane operation thus only involves an adjustment of the (in FIGS. 8 and 9 in more detail described) stop of the carriage 15. f

FIGS. 5 and 6 show, analogously to FIGS. 3 and 4, the Clamp conveyor in the middle of the working width

lying operating station B5. From this station you can 25th

the item of laundry can either be centered with respect to the center line 13 or conveyed to the left or right where it is centered on the center line 49 of the partial web 11 or the center line 50 of the partial web 12, depending

according to which of the two partial webs is currently receptive 30th

is.

For this purpose, both carriages 24 and 25 can be freely displaced with respect to a pulling element 54 within certain limits. The on

59 formed, which - depending on the direction of movement of the pulling element 54 - either moves the right carriage 25 to the right or moves the left carriage 24 to the left.

On the upper side of the pulling element 54 three stops 55, 56 and 57 are fixedly attached, the stop 55 in the middle lies and the stops 56, 57 mirror-symmetrically at a distance from the stop 55. Furthermore, the stops are in The transverse direction of the pulling element is arranged in three different tracks 51, 52 and 58, which are opposite to one another by a track width are offset. Both carriages 24, 25 in turn have adjustable stops which are set in this way can that the stop of the left carriage 24 cooperates with the stop 55 or the stop 57, during the Carriage 25 has an adjustable stop which can be adjusted so that it is either with the stop 55 or the stop 56 cooperates.

2Q First of all, it is assumed that the item of laundry compared to the Center line 13 should be centered. It is also assumed that the pulling element 54 is moved so that the driver 59 runs to the right. The stop on the carriage 24 is then set to the stop 55 of the track 52. As soon the driver 59 sets the carriage 25 in motion, the stop 55 of the track 52 also arrives with the stop the carriage 24 in contact, so that both carriages are moved in opposite directions simultaneously, whereby the item of laundry stretched and centered to the center line 13

_{g0 is} trated. In an analogous manner, when the driver 59 moves to the left and thus the carriage 24 moves through the driver 59, the corresponding stop on the carriage 25 can be set on the track 52 and thus the driver 55, so that an analogous sequence of movements results.

The guide rod 64 is screwed to the carriage 15 via a nut 76 with a threaded end piece that protrudes through a bore 75 through a side wall of the carriage 15. The guide rod 74 has two recesses 77 and f 81, which is disposed here on the side facing the pulling member 32 side of the guide rod 64th The two locking recesses 77, 81 are spaced apart at a distance 53, which corresponds to the track spacing. Furthermore, the two locking recesses 77 and 81 are aligned with the center of the tracks and thus with the center of the

Ij strike 47 or 48. The stop 60 has a hollow |

space 78, which is at right angles to guide rod 64

runs. In the cavity 78 there is a compression spring 79 brings as well as a ball 80, which from the compression spring 79 | is pressed in the direction of the guide rod 64, where it then with the appropriate position of the stop 60 in one of the locking recesses 77 or 81 engages. In this way, a perfect fixation of the stop 60 is achieved.

From FIG. 9 it can also be seen that the pulling element 32 is guided by a slider 82 which has a recess 83 with inclined side edges, whereby the Zuqorgan 32 is supported and automatically centered. The slider 82 is connected to a side wall of the carriage 15 and is additionally supported by a girder reinforcement 84. This ensures that the stop 60 of the carriage always comes into effective contact with the associated stop 47 or 48.
