NL1008927C2 - Form drying of outer garments, especially coats or jackets, cleaned by wet process - Google Patents

Abstract

The garment (3) is placed over a mannequin form (1) and held there by vacuum whilst a press panel (4), hem clamp (6) and sleeve clamps (7a, 7b) are pressed against it, after which the garment is dried by hot air emerging from the form. A method for drying outer garments, especially coats or jackets, which have been cleaned by a wet process comprises placing the wet garment over a drying mannequin acting as a form and generating a vacuum force inside the form to suck the fabric stretched over the form and therefore the garment against the outside of the form and cool and dry it. A press panel is urged against the front side of the garment, a separate clamp is attached to the bottom hem, and clamps are attached to both sleeves, then the hem clamp is closed and moved away from the garment in order to keep the garment straight and away from the mannequin, whilst the sleeve clamps are moved downwards to keep the sleeves straight. Air is blown out from the breast region of the mannequin at a temperature of 120-180 degrees Centigrade, causing the fabric stretched over the form to billow, along with the garment, and after 3-5 minutes the garment has been dried without creasing. An Independent claim is also included for the form drying apparatus.

Description

Method and device for drying clothes

The invention relates to a method for shape drying of wet-cleaned outer clothing, in particular a cobert or coat, comprising the following steps: the wet outer clothing is placed on a drying doll, provided with a shaping cloth; by means of an underpressure in the drying doll, the shaping cloth and a front side of the outerwear are sucked in and thereby cooled and dried; the front of the outerwear is pressed against the dryer using a pressure panel; a divided hem clip is placed on a bottom seam of the outerwear; a cuff clip is placed on each of the cuffs; the hem clip is closed and moved outward to pull the 15 sides and the back of the outerwear tight and free from the dryer; the cuff clips are slanted downwards in line with the sleeves to tighten the sleeves; air with a temperature of 120-180 degrees 20 is blown out from a breast part of the drying doll, whereby the molded fabric bulges, such that the outer clothing also bulges up and acquires a substantially wrinkle-free appearance, after which in a period of 3-5 minutes the outer clothing is at least substantially dried.

Drying clothes on a drying doll is known. This concerns thin single clothing, such as work aprons, shirts and hospital clothing. For multilayer garments, which are easily creased and felted and, moreover, are subject to shrinkage, such as jackets, the opinion in the art is that wet cleaning, which actually means washing in water, cannot lead to good results. More precisely, washing as such is possible, but at least partly the shape of the clothes is lost during subsequent drying.

1003927 2

In order to successfully apply the inventive method, it is important to wash the garment with the utmost care in such a way that virtually no mechanical forces act on it. Also, the garment 5 should not be compressed and spun after washing. Washing methods of this type are known in the art, but they are not applied to outerwear such as jackets and jackets, because subsequent drying thereof is considered impossible.

10

The inventive method has not been developed so much because the more common method, using perchlorethylene instead of water, is unsatisfactory. The actual motive for this development is the concern for the environment. The modern view is that the use of large amounts of harmful perchlorethylene for simple cleaning purposes is actually not acceptable. The aim of the inventive method is therefore the wet cleaning of outer clothing with an acceptable washing result for an acceptable price. The last aspect requires far-reaching automation and a short lead time. Both aspects are realized in the inventive working method. The time a jacket spends on the manikin is about five minutes, while a manual post-treatment is generally not necessary.

The invention also relates to a device for shape drying of wet-cleaned outer clothing, in particular a jacket or coat, which device comprises a drying doll covered with a shape cloth on which the outer clothing can be placed, and pumping means for pressurizing a interior of the manikin, and a pressure panel provided with first actuator means for securing a front of the outer garment in the operative condition, and a composite hem clip, in the 1008927 3 operative condition gripping a lower hem of the outer garment on two sides and a back, and second actuator means for closing and pulling the seaming clamps outward at least substantially at the same time, and two cuff clamps for clamping and obliquely pulling down the cuffs in use condition using third actuator means, and second pumping means and heat generating means for it through the interior of n supplying the drying doll to the outer clothing 10 with air at a temperature of 120-180 degrees, and operating means for operating the actuators and the pumping means.

A favorable embodiment of the invention, which requires little floor space, is characterized in that the device is provided with a composite cabinet, comprising an upright part and a horizontal part, the first and second pumping means and the heat generating means in the upright part. and that the dryer is placed on the horizontal part.

The invention will now be further elucidated with reference to the following figures, in which: 1 shows a possible embodiment of the device;

Fig. 2 schematically shows the device at rest in longitudinal section;

Fig. 3 schematically shows the device in a second operating mode in longitudinal section;

Fig. 4 schematically shows an alternative embodiment of the device in cross-section, FIG. 5 schematically shows the alternative embodiment of the device 35 in a horizontal section.

1008927 4

Fig. 1 shows a possible embodiment of the inventive device, in which a drying doll 1 is fixedly arranged on a composite cabinet 2. Dry doll 1 is actually a metal body which is provided with an opening at the front and possibly at the rear. A fabric or felt molded cloth is draped over the dry doll 1, which is provided with arms and the top of which is permeable to air. A wet jacket or jacket 3 is hung on drying doll 1, or actually on the molded rug. The collar is put upright and the lapel is slammed and in vacuum doll 1 a vacuum is created which sucks the front of jacket or jacket 3 against dry doll 1. This can be corrected manually if necessary to prevent (folds or folds. Then a pressure panel 4 is pressed against the front of the jacket or jacket. Then, a composite seam clip 5 fixed on a plateau 5 is opened in an open position. moved up until the hem of the jacket is included, then composite hem clip 6 is closed and moved outward 20, so that jacket or jacket 3 on the sides and at the back are free from dry doll 1. The cuffs of the jacket become in two cuff clips 7a, 7b included, and sloped downward so that the sleeves are stretched.

25

Subsequently, warm air is blown into dry doll 1, which escapes partly through the outerwear and partly between the molded jacket or jacket 3 via the molded cloth. The shaping cloth hereby bulges and has a stretching effect on jacket or jacket 3, while the passing air has an ironing effect. After a few minutes, jacket or jacket 3 is dry, seam clip 6 and pressure panel 4 are removed and jacket or jacket 3 is taken from the dummy 1 and after a visual inspection it is placed on a coat hanger and hung in a drying tunnel for example 1: 10 0 8927 5 to remove moisture. Dry doll 1 is placed on composite cabinet 2, which contains actuators, pumps, valves and a heat exchanger.

FIG. 2 schematically shows the device in rest in cross section. Dry doll 1 is again designed as a metal hull, in which holes have been made to allow air to pass. Dry doll 1 is covered by a fabric or felt molded carpet 8 and is connected via tunnel to an upright part of 10 assembled cabinet 2. The upright part contains an air pump 9, an air inlet 10, an air outlet 11 and a heat exchanger 12. There are two operating modes.

In the first mode of use, pump 9 is used to create a negative pressure in drying doll 1. A valve 13 is hereby folded upwards, so that heat exchanger 12 is out of use. Furthermore, air inlet 10 is closed and air outlet 11 is opened. Pump 9 will now pump and exhaust air from dryer 1 and this through air outlet 11. This mode of use 20 is used to pull a wet garment against the front of dryer 1 and to suck away moisture and to cool the garment and dryer 1 and mold 8. .

In the second operating mode, pump 9 is used to supply warm air to dry doll 1. In this case valve 13 is folded down, so that heat exchanger 12 can transfer heat to passing air. Furthermore, air inlet 10 is opened and air outlet 11 closed. Pump 9 will now pass air obtained via air inlet 10 past heat exchanger 12, in which the air is heated to about 150 degrees and convey this air to drying doll 1. Heat exchanger 12 is heated with electricity or with steam.

Furthermore, FIG. 3, the pressing panel 4 in a passive state, together with first actuator means 14, here 1003S27 6, are designed as a pneumatic actuator. Also, FIG. 2 one of the three zoom clips of composite zoom clip 6, also in a passive, open position. Also visible is one of the three pneumatic actuators which together form the second actuator means 15 and which operate composite zoom clamp 6.

Composite zoom clamp 6 and second actuator means 15 are attached to platform 5, which can be moved vertically along a column 16, for example via a motor-driven screw spindle. This can be done manually, but also automatically, for example with a photocell that can detect the difference between shaping cloth 8 and a garment and control the motor until zoom clamp 6 has reached the correct height.

Fig. 3 shows the device in the second mode of use, in which pressure panel 4 presses the front of jacket or jacket 3 against dry doll 1, or actually against mold cloth 8.

20 Composite hem clip 6 holds the seam of jacket or jacket 3 all around and pump 9 blows air from air inlet 10, via heat exchanger 12 into dry doll 1, which air escapes partly through and partly along jacket or jacket 3, leaving jacket or jacket 3 dried and is ironed. Form rug 8 25 hereby bulges and has a stretching effect on jacket or jacket 3.

If steam is available, it may be useful to release some steam into drying doll 1 at least once per treatment, which steam mainly escapes along and through the back of jacket or jacket 3 and thereby has a stretching, wrinkle-removing effect.

Fig. 4 schematically shows an alternative embodiment of the device in cross section. Dry doll is 1 s! 1008927 7 reduced to a column 16, provided with shoulder pieces 17a, 17b and a mounting edge 18 for molding cloth 8. Furthermore, an opening 19 in the front and the back of column 16 is visible, with the hole in the front 5 being mainly functional in the first mode of use, for admitting the underpressure on the front of jacket or jacket 3, and the hole in the back is mainly functional in the second mode, for admitting the warm air. Furthermore, two of the zoom clamps of 10 composite zoom clamp 6 and the cuff clamps 7a, 7b are visible, together with the third actuator means, here consisting of the pneumatic actuators 19a, 19b. Cuff clamps 7a, 7b are drawn separately, which occurs when jacket or jacket 3 is almost dry, to also allow the cuffs to dry.

Under these circumstances it may be useful to slide cuff tensioners into the sleeves, which tension the cuffs laterally during drying. Also visible are two pipes 20a, 20b from which, if necessary, steam can be blown into drying doll 1.

20

Fig. 5 schematically shows in a horizontal cross-section the alternative embodiment of the device, illustrating the placement of the composite hem clip 6 and the way in which it engages jacket or jacket 3.

In addition, the position of platform 5 and column 16 is also indicated, as is the position of column 16. Shoulder pieces 17a, 17b are also indicated for clarification, although they are strictly invisible in this section.

30

It goes without saying that single outer clothing, such as shirts, hospital clothing and work jackets, can also be washed according to the inventive method and with the inventive device.
