Description

The invention relates to a folding machine for items of laundry, in particular for underwear, in which Several transverse folding devices are arranged one behind the other in the conveying direction of the material to be folded.

In the case of Abwälzfolding machines that are used in laundries to fold ironer or flattened laundry and the like, the starting edges of the folded goods running on the conveyor belt are usually lifted and held, while the remaining part of the folded item under the held starting edge Unrolling moves through it until the rear end of the folded item is below the fixed starting edge arrives, after which the clamping plate falls off and the top layer falls on the base of the folded item. if the once folded item of laundry is then to be folded transversely, it has sometimes been observed that the once cross-folded object is not always in the most suitable form for further processing or the cross folding is located. For example, lie when a household apron is folded which has a portion which is placed over the head around the neck of the wearer and which has ribbon-like portions which are tied around the waist of the wearer after two Fold and cross-fold parts of the neck band and the waist bands on the top of the folded object, where they can get messy and shift.

The aim of the present invention is to provide a folding device in which collapsed Objects have a nice and decent appearance.

This is the case with folding machines for items of laundry, in which one behind the other in the conveying direction of the folded goods a plurality of transverse folding devices are arranged, achieved according to the invention in that the first transverse folding device a turning device is arranged downstream.

This additional arrangement of the turning device after the first folding device achieves that those parts of the laundry, for example ribbons, loop-shaped parts and the like the turn after the first fold in the subsequent folds in the interior of the item of laundry are located so that they do not interfere with the appearance of the folded by shifting and the like Items of laundry can cause more.

The turning device arranged according to the invention is designed in a manner known per se as a liftable clamping plate controlled by a button, light beam or the like with a double stroke, which during the turning process the gripped edge of the laundry folding machine for laundry items,
especially for underwear, in which one behind the other in the conveying direction of the folded goods

several cross folding devices
are arranged

■.-.-., _R 3 4 In FIG. 1, a household press to be folded is able to be used as an example of a folded item to be folded against a stationary terminal strip u. The terminal strip u and the terminal apron are shown. With α the edge of the counter is lever-s include slots through which designates the forward object, the g for conveying it to the end of the follower arm, as shown in FIGS. 12 and 13, a conveyor belt, which itself is not shown, the 5 can be seen, can pass through.

With b is the neck band and tang ν can be the lower space of the cylinder k, under with c the bands are designated, by means of which the piston t, compressed air is supplied or from there the apron is tied around the waist of the wearer. be derived. FIG. 2 shows the apron after a one-off case. In the position according to FIG. 10, the object has e direction, whereby the leading edge α on the rear io does not yet reach the feeler arm /, whereby the downward end of the folded object to lie down cylinder k hangs on the stationary piston m , comes and the neck band and the waist bands c In the position, as it can be seen in Fig. 11, this is lines lie. Been 's sensing arm moves from its position, so that Fig. 3 shows the article after a second pressurized air through the tube / into the upper end of the folding, it being seen that the neck band and cylinder k has stepped over the piston m , leaving the waist bands in the fold line and the rest of the Cylinder around the stroke of the upper piston ρ and these parts lie in the bottom of the object. is lifted with the lower piston in the cylinder Fig. 4 lets the object gleierkennen after a transverse folding corresponding to the two piston paths downwards, where the parts of the neck band b and a tet, without the clamping plate raised waist band c on the top, the rest of this 20 is.
