Definitions

• the invention relates to a method and a device for smoothing clothes.
• the fibers of a piece of clothing can be so kinked over time that the kink is impressed in the fiber structure in such a way that the fiber tends to the kinked state in the relaxed state without any external mechanical influence.
• a smoothing process can only achieve no smoothing effect with the help of steam and heat without mechanical action.
• the present invention has for its object to provide a method and a device for smoothing garments, with which an improved smoothing effect is achieved, whereby the garment to be smoothed is protected.
• a smoothing effect can be achieved with little effort, which is also very gentle on the item of clothing.
• the gas jet can be pressed into the fabric of the garment in places or a tensile force can be exerted on the entire garment, as a result of which it is tensioned. Any wrinkles that may be present are smoothed in this way.
• This smoothing effect of the gas jet can be increased by relaxing the fabric of the garment before the smoothing process or at the beginning of the smoothing process, by moistening and heating the fabric of the garment.
• water vapor can be mixed into the gas jet and can thus be directed onto the fabric. It is also possible to sprinkle the garment with water, the water being sprinkled by means of the nozzle with which the gas jet is directed against the garment or by means of a separate nozzle which is not used to generate the gas jet.
• a force is necessarily exerted on the garment by the at least one gas jet. This can adversely move the garment and possibly crease it. This can be prevented, for example, by using a gas jet which has a high outflow rate but a small diameter. This means that the gas jet as a whole does not exert a large force on the garment and therefore has little influence on its position, but can nevertheless achieve a high tension effect on the fabric and thus a high smoothing effect in a small area on the garment. It can be provided that the deflection due to the gas jet is at least partially compensated for by hanging the clothes by pulling the suspension of the clothes somewhat towards the nozzle from which the gas jet flows.
• the garment is advantageously supported during the application of the gas jet. This can prevent the garment from being moved by the force of the gas jet. Furthermore, a stronger gas jet can be used and a better smoothing effect can be achieved.
• the support can be done by means of fixed supports such as at least one support surface. If the item of clothing is moved, for example, to pass through several treatment stations, such supports can also be set up in such a way that they can move with the item of clothing. For example, at least one support roller can be used, which is rotatably mounted about an axis, which is oriented at least substantially perpendicular to the direction of movement of the garment.
• the garment is supported by a gas jet. In this embodiment, the garment is subjected to at least one gas jet from both sides. In this way, imprints in the tissue can be avoided, which can occur with solid supports. Furthermore, the smoothing effect is enhanced, since a force is exerted by a gas jet from both sides.
• the gas jets acting from both sides can in particular be matched to one another in such a way that the section of the garment in between is deformed in a certain way in order to achieve a good smoothing result.
• the force exerted by the gas jets from both sides can each be distributed over a certain area with a non-uniform force distribution.
• the force distributions over the surfaces on both sides can be set differently, so that in one section of the garment the force exerted by the first side on the section is greater than the force exerted by the other second side and in an adjacent section that by the second Side force prevails.
• the garment can be deformed in a defined manner, so that it assumes, for example, a corrugated shape or elevations are formed in one or the other side in the garment.
• a gas jet can be used on one side, which widens like a cone and is hollow on the inside, so that it exerts a force in an annular area on the surface of the garment, and a gas jet can be used on the other side that exclusively generates a force in a small point or circular area, the point or circular area being located within the annular area of the force exerted by the opposite side.
• This causes the fabric of the garment to be stretched and smoothed between the annular region and the point or circular region lying therein.
• an essentially linear surface pressure can also be selected.
• the force in these areas can be tensioned and smoothed with a force acting in different directions in adjacent areas.
• the forces acting from both sides can be coordinated in such a way that the garment is held in a certain local area and, in particular, it is prevented that the garment comes into unwanted contact with other parts, where can be prevented by contamination or wrinkling. Since the force of a gas jet used decreases with the distance from the nozzle, the arrangement, the alignment and the outflow characteristic of opposing and opposing nozzles can create a control system which tries to keep the items of clothing at a specific location between the nozzles.
• the location of the item of clothing or a section of the item of clothing is recorded and the recorded location is used as the input variable of a control system which regulates the gas jets acting on the item of clothing from different sides in such a way that the item of clothing or section of the item of clothing is always at a predetermined target location or target location area.
• the location detection can be carried out with light barriers or reflex light barriers, whereby other methods for distance measurement or location detection can also be used, for example by means of ultrasound.
• the fabric of the garment can be stretched gently but at the same time vigorously and thus achieve a high smoothing effect.
• the force distribution and / or the total force exerted by the individual sides can be changed over time, so that an alternating deformation is achieved, which can have an advantageous effect on the smoothing process.
