The hollow space of the holding body 52 is furthermore connected via a hose 55 to a controllably switchable suction device 53 (turbine) (see FIGS. 1 and 4). Further, the section 51 is provided with a suction hole 54 at least in the area supporting the collar and the vertically folded part of the garment, so that the garment that has already been folded vertically and is in contact with the section 51 will not slip when the suction device 53 is actuated. It is held on the part 51 without any problem.

The transverse folding device 25 has a lower part and an upper part formed as transverse folding flaps 42, 43. The transverse folding flaps 42, 43 and the portion 44 located therebetween are parallel to each other and spaced apart from each other and the intermediate member 2
It is designed as a number of rods 45 which are also arranged parallel to the pivot axis 38 of 8 and are fixed or supported on lateral holders 46 (see FIG. 5). The holding body 46 is arranged on the opposite side of the portion 51 of the intermediate member 28 from the holding body 52 with respect to the longitudinal center line of the transverse folding device 25 . Horizontal fold flap 42,
43 indicates arrows 49 and 50 centered on axes 47 and 48.
It is possible to swing back and forth in the direction of. Horizontal fold flap 4
2 and 43 are rotated by a known drive device (not shown).

The portions 51 of the intermediate member 28 of the longitudinal folding device 24, their mutual spacing and the diameter of the bars 45 of the transverse folding device 25 are such that the intermediate member 28 pivots from the V-shaped position to the rearward position shown in dashed lines (FIG. 1). It is chosen in such a way that it can pass through the transverse folding device 25 during movement.

The transverse folding device 25 further includes transverse folding flaps 42, 4 after the intermediate member 28 of the longitudinal folding device has passed through.
It is formed so that it moves from its basic position to a stacking position located on the side of this basic position as shown by the double arrow 57 while performing the horizontal folding according to No. 3, and then returns to the basic position again.

8. The frame 63 with the stacking table 59 and the discharge conveyor 15, as well as its drive, are functionally properly supported in the machine frame 10 in a known manner. The frame 63 is connected to the stacking table 59 by, for example, running rollers 70 and guide rails 71 (FIG. 7).
are guided by running rollers 72 and guide rails 73 (FIG. 5), respectively. The stacking table 59 is furthermore designed in the form of a rake in its supporting part, so that the webs 68 of the rake extend downwardly from the conveying plane of the discharge conveyor 15 during its descending movement, in other words between a plurality of belts 69 spaced apart from one another. It is formed so that it can be passed through downward. The clothes placed on the web 68 of the rake are thereby transferred onto the belt 69 or onto the discharge conveyor 15.

The illustrated device has the known components required for the drive, such as in particular an electro-pneumatic control device for the pneumatic and electrical control of the device.

Next, the operation of this embodiment will be explained.

A garment (not shown) placed on the support plate 11 or 12 and held by a hanger-like device 16, for example a top layer, can be folded into the vertical folding device 24 or two vertical folding flaps 29 by pivoting the support plate 11 or 12. , 30 and an intermediate member 28 located therebetween. Immediately the table plates 26, 2 placed under the vertical folding flaps 29, 30
The suction devices 31, 32 of No. 7 and the suction device 53 of the intermediate member 28 are activated. The hanger-like device 16 is then unclamped, the device 16 is moved upwardly away from the garment, and the support plate 11 or 12 is pivoted back into the V-shaped position relative to the folding device 13. In this state, the clothes do not shift due to the suction force, and are folded into the vertical folding device 24 or the section 2.
8 to 30. Immediately thereafter, the suction devices 31, 32 are switched off and the longitudinal folding of the garment takes place in the direction of the arrows 35, 36 by a follow-up controlled movement of the longitudinal folding flaps 29, 30. As soon as this is finished, the intermediate member 28 is swiveled into a rearward position (indicated by dash-dotted lines in FIG. 1). The garment is then transferred to the cross-folding device 25 by the intermediate piece 28 passing through the rake-like garment support surface of the cross-folding device 25, and during this transfer the suction device 53 of the intermediate piece 28 is shut off. The garment, which has now been vertically folded and placed on the garment support surface of the transverse folding device 25, is then held in place by pressing a holding member (not shown) in the region of the transverse folding point. By crimping this holding member, arrows 49 and 50
During the cross-folding of the lower and upper parts of the garment due to the follow-up controlled movement of the cross-folding flaps 42, 43 occurring in the direction , the garment does not slide and does not jump up. The transverse folding takes place while the transverse folding device 25 is moved from its basic position to the stacking device 14 arranged to the side of this transverse folding device. The transverse folding flaps 42, 43 are then still in the swiveled position when the stacking position is reached. The clothes are sandwiched between rod-shaped members 42 to 44 of the horizontal folding device 25 and stacked in the stacking device 1.
4. The subsequent stacking of the now vertically and horizontally folded garments is introduced by pressing down on the clamping jaws 62 above the two clamps 58 of the stacking device 14 to secure the garments. The transverse folding device 25 is then moved back to its basic position after the aforementioned holding member (not shown) is released and is then pulled out of the garment. Immediately after pulling the transverse folding device 25 out of the garment, the clamps 58 are opened and then moved laterally away from the garment area. By pulling out the horizontal folding device 25 and opening and moving the clamp 58, the garment is placed on the stacking table 59 located below it or on another garment that has already been folded and placed on the same table. . The stacking table 59 is lowered by the height or thickness each time one garment is stacked,
After stacking a predetermined number of clothes, the rake web 6
8 passes downwardly between the upper sections of the plurality of belts 69 of the discharge conveyor 15, thereby depositing the stacked garments onto the belts 69 of the discharge conveyor 15. Then the discharge conveyor 15 is moved by the arrow 67
The stacked clothes are thereby removed from the working area of the stacking table 59. The stacking table 59 is then returned to its upper basic position again. Similarly, clamp 5
8 is returned to its basic position from the side position after each garment is placed on the stacking table 59.

The stacked clothes are fed by a discontinuously operating discharge conveyor 15 to a continuously operating transport device (not shown), which transports them onto shelves after mechanically wrapping them if necessary. Supplied. In this case, a worker is not required on the delivery side of the device.

The illustrated apparatus and its mode of operation can be used or applied to the folding of different types of garments. In this case, it is sufficient to carry out various operations adapted to the various configurations when placing the garment on the support plates 11, 12 and when positioning the garment correctly on the support plates. This operation will be easier if the fabrics stretched over the support plates 11 and 12 are translucent and a lighting device is placed behind them. For lightweight clothing, support plate 1 is placed in the upper area of support plates 11 and 12.
As an auxiliary holding device for the clothes placed on 1, 12, it is advantageous to provide a suction device which can be controlled and switched from behind.

Effects of the Present Invention According to the present invention, after the first garment is mechanically transferred from the support plate to the folding device, the second garment can be placed on the support plate at the same time as the first garment is vertically folded. When the first garment is fed to the folding device and folded vertically, the first garment can be folded horizontally and fed to the stacking device simultaneously. Therefore, processing time and preparation time can be overlapped, improving operational efficiency. increases.
