DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENITON
This invention relates to a method of ironing articles of clothing, such as jackets, shirts, overcoats and the like, preferably by continuous operation, and to an apparatus for carrying out the method, wherein hot air jets are directed symmetrically from top to bottom onto both sides of the articles through a plurality of superimposed nozzles which are inclined downwardly about 45.degree. to the plane of movement of the articles.
Ironing of articles of clothing, in particular those made of an industrial scale, is at present performed by pressing operation, more specifically by means of two opposite conveniently heated plates which are closed on the article while suspended on a hanger, put on a dummy, or lying in spread condition. This method has a number of disadvantages.
In a first place, the two opposite plates can usually only iron the front and back of a garment, whereas it is desirable that the sleeves thereof should be ironed separately.
Moreover, the article of clothing has to be put with care on its support in order to prevent formation of folds which may cause creases to appear on the ironed articles after pressing.
These ironing machines are, obviously, of a discontinuous-operation type, in that a single article is fed at a time between the opposite press plates, so that their working rate is rather low.
SUMMARY OF THE INVENTION
From AT-A-370790 an apparatus is known by which a method of ironing articles of clothing is carried out, wherein opposite hot air jets are directed onto the two larger sides of the articles which are suspended on hangers and which have been previously wetted.
The opposite air jets act to impinge upon the article in a direction from top to bottom so as to maintain the article in a state of vertical tension during the treatment.
The object of this invention is a method and an apparatus to ensure through ironing of an entire article of clothing by a very rapid process.
This object is acheived according to the invention which provides a method of ironing articles of clothing by means of hot air jets which are directed from top to bottom towards the treated article so as to evenly impinge upon it, thereby to keep the article in a stretched state on its hanger or any other support means on which it is suspended, said air jets are being directed so towards the two opposite sides of a previously wetted article as to be inclined through substantially 45.degree. to the plane of said article. At the end of the ironing operation, the article is cooled by means of cool air jets that are oriented in the same direction as the preceding hot air jets.
The process is, with preference, carried out continuously, that is with the articles being moved on a constant speed during the treatment.
The apparatus for carrying the method into effect is, preferably, one of a linear type and is comprised of modular sections each having a centrally disposed tunnel through which the articles suspended on corresponding hangers carried on a conveyor chain, are fed.
In a first of said sections the articles are wetted by means of an air-water atomizing system comprising a series of adjustable atomizing heads arranged on both longitudinal sides of this section.
Following said wetting section is a drying-ironing section comprising an array of radial fans which draw in hot air and discharge the hot air symmetrically towards the two sides of the articles moving in the section, through downwardly oriented nozzles that are included about 45.degree. to the plane of movement of the articles.
In this way, the hot air jets impinging in an evenly distributed manner upon a garment, in addition to drying it, also achieve thorough ironing thereof due to the tension exerted from top to bottom upon the article by said hot air jets.
Provided at the ironing section is an exhausing conduit for removing moisture and charging air.
Finally, a cooling-stabilizing section is provided and has, in turn, fans that are arranged to direct on the ironed articles cool air drawn in from the outside.
