Method and device for joining two textile surfaces '

The invention relates to a method and a device for connecting two adjacent textile cloth surfaces using an adhesive., It relates generally to cloth treatments as well as wrinkling or wrinkling Pinching of textiles, especially of garments or parts of garments and on the fastening or joining of such textile cloths, cloth parts, garments or other textile articles,

The object of the invention is to create a suitable one Method and a corresponding device, after which the desired cloth treatment of the type mentioned in a simple Way and while avoiding the disadvantages of known methods and devices can be achieved.

409823 / 08O ₂

According to the present invention, a method of fastening or connecting two textile cloth surfaces aligned relative to one another proposed according to which a solid element with a sticky adhesive surface, which is for gripping or holding the cloth surface is sufficient, is attached to at least one of the surfaces, the second cloth surface in the desired Position is arranged relative to the first cloth surface and wherein the parts are pressed together to achieve the bond will.

The formation of so-called 'permanent ^I- folds or tricks has been studied over many years. When using natural fibers, such folds or tricks can only be achieved by special treatments, which usually have the disadvantage of high costs and considerable effort. In the case of synthetic, thermoplastic fibers, such folds or creases can often be produced by a simple heat treatment, but the required temperature is above that which is available, for example, in the usual production of clothing. In the case of jersey cloths, for example, folds or creases have been fixed by stapling or quilting, but this does not give the garment a completely satisfactory appearance.

It was not only found that wrinkles. Or twists through Presses can be fixed in the presence of adhesive or adhesive, but that the adhesive or adhesive can be fixed accurately and quickly can be applied if it is in the form of a solid thread or yarn or a cord. Hence the invention encompasses Among other things, a method for applying folds or creases on cloths with the aid of an adhesive and further a dispensing member for applying the adhesive along a selected line of the sheet.

According to a preferred embodiment of the method according to the invention, a solid thread or a corresponding cord is included an adhesive adhesive surface along a selected line on the textile cloth, the cloth being used to enclose the

409823/08

Thread or glue folded along the line and the folded Cloth is pressed, unu a fold or a crease along the selected Lock line. It is preferred that the cloth first briefly a fold or a crease along the selected Line is attached as this procedure helps guide the thread or cord into the appropriate position.

The tacky adhesive surface can be provided by an adhesive composition can be achieved, which itself is responsible for fixing the fold or the crease, in which case the thread or the Cord made of a neutral or insensitive material, for example consist of cotton and peeled off if necessary can be before the fold is pressed and fixed. Alternatively, it is possible in a preferred manner that the thread or Cord is thermoplastic or activatable in some other way to serve as an adhesive or glue, the sticky adhesive surface can serve to hold the thread or cord in the respective position while the cloth is folded and pressed. The adhesive surface can be made by coating a thermoplastic Fadensjoder - an appropriate string with a liquid glue composition can be achieved. Alternatively, the surface of the thread or cord can be softened, for example with a solvent, but with sufficient adhesiveness must be achievable for the purpose of the invention, namely to firmly adhere to the cloth surface until the complete Adhesion or gluing is achieved by pressing.

A particular advantage of the method according to the invention for generating of folds or kinks consists in the fact that very fine threads or yarns normally 0.1 to 0.5 mm and preferably about 0.3 mm in diameter can be used. It was surprising found that such thin threads or yarns are permanent Wrinkles or twists result in an unconventional look differentiate between the pressed-in folds or nips. this is of course of great importance if the product is to meet commercial requirements.

The formation of a fold or a crease in the manner described can be considered an act of connecting or securing two adjacent pieces of cloth are considered, each lying on one side of the fold line, namely in a predetermined relative position to each other.

According to a second aspect of the present invention, this principle is applied to the securing or fastening of a connection of Textile doors applied. After that, parts of textile doors are made connected by attaching a solid element with a tacky adhesive surface to the surface of one of the parts is, after which inclusion of the element or adhesive the another cloth part is applied to the first-mentioned surface and wherein the arrangement of the cloth parts is pressed together. As a result, they are bonded together with adhesive.

In a preferred manner, a thermoplastic thread, a yarn, a strip or ribbon or a cord is used with a pressure sensitive or pressure-sensitive adhesive or adhesive coated to achieve an initial fixing or anchoring of the tape is used. The final bond between the cloth parts is made by softening the thermoplastic tape underneath Preserve heat and pressure.

The tape and adhesive can be of any composition have, which granted properties suitable for the cloth parts to be connected. Various materials have already been described and below are various forms of a dispensing member for supplying an adhesive coating carrying thread, although it is of course not absolutely necessary, these individual forms of distribution members to be used when connecting pieces of cloth to one another. Other forms of distribution links can also be used can be used, and for example a thermoplastic nylon yarn can be fed from a rack or delivery plant, which is separated from a distribution member for attaching the adhesive to the thread or the yarn and from this a partition +) described - 5 -

stand has. Furthermore, other ways of attachment can also be used a sticky, adhesive-coated tape on cloth parts will be labeled.

The thread, the yarn or the fiber is preferably the Strip or tape in accordance with the shape of the to connecting area preformed.

According to the present invention there is also a method for Joining parts of sheet material in a predetermined Area suggested. Then a pre-formed thermoplastic sheet, the shape of which corresponds to the area, is used an adhesive applied to one of the parts, the other Part of the leaf material including the leaflet on the the first part is applied and heat and pressure are applied to cause the leaflet to join the two parts.

The adhesive for fixing the fold or the crease or for connecting the cloth is, either in the form of a thread or yarn or as a liquid composition, preferably selected so that it can be bonded by hot pressing and thereafter, it is resistant to detergents and dry cleaning agents. In the case of a thermoplastic thread, this should preferably be fusible at a temperature which is normally achievable with a Hoffman press or a domestic iron, but which is preferably far enough below the temperatures which lead to the destruction of the cloth to be treated can. It has been found that monofilament arrangements are most satisfactory. Preferred thermoplastic threads are made of nylon with a strength of 75o or 135o denier, soften at about 100 ° C and are. under the trade name. 'Kleintex ¹ available. Another and less easily applicable thread consists of nylon fibers with a smaller denier value, softens at 125 C and is available as Staflex ".

Also in accordance with the invention is a dispensing member for applying a tacky adhesive composition and an associated thread or yarn along a preselected line of a cloth prior to folding and pressing of the cloth provided along this line. The distribution link contains a receptacle for the adhesive, one end Outlet nozzle and an inlet remote therefrom are provided. The inlet and outlet nozzle each have an opening with a diameter that allows the thread or yarn to pass into and out of the reservoir, and however prevents the adhesive from flowing freely. Also connected to the container structure adjacent the inlet is means for feeding the thread or yarn into position assisted to enter the inlet.

The receiving container or /. the reservoir is preferably completely or formed in part by the body of the distribution member and can be shaped for convenient hand holding. The end of the container in the area of the outlet nozzle is preferably inclined, so that the nozzle in use is in close contact with the Cloth can be brought. The container can also be sealable Have opening, for example, at its end facing away from the outlet nozzle, through which a filling with adhesive can be done.

According to the preferred practice corresponding to the first aspect of Invention becomes that which is to be folded or to be provided with a trick Cloth first folded and pressed along the selected line or lines. After that, it will be with its inside on top the folding, laid out; and the free end of a thermoplastic and thread coated with a tacky adhesive is placed under Exit from the outlet nozzle of the distribution member pressed into the fold to remain at one end of the line. The distribution link can then be quickly pulled along the line to its other end, with the thread in its position along the Line remains. The "weight and tension of the thread etrmöcj borrowed a slight guide along the desired line while

the sides of the previous fold will help guide the thread in an exactly required position along the line.

The cloth is then wrapped around with the thread in place the line folded over and then pressed at a temperature which is sufficient to soften or melt the thread however, it has not yet caused any destruction of the cloth. In this way can be a largely permanent crease or an equivalent Trick can be made very easily.

By choosing suitable materials for the adhesive and the Filament treatment conditions suitable for certain cloth materials and circumstances can be achieved. For example, if a thermoplastic thread with a melting point near 100 C is used, the fold or crease can be obtained by using a conventional Hoffman press is usually available as equipment to a clothing manufacturer and in most cases without the risk of destroying the Cloth can be used. This means that a satisfactory result can be achieved not only with natural fibers such as wool, but also ■ in synthetic and thermoplastic fibers can be achieved without special cloth treatment equipment.

The present invention is in the manufacture of a wide range can be used for cloth articles, for example in the clothing and decoration fabric industry. Examples of after this Fabrics that can be connected to processes are cloths, upholstery and Upholstery fabrics, stretch fabrics and tarpaulin and canvas.

If a fusible thread is used, it should be preferred have a diameter of 1 to 3.5 mm, and a diameter of 2 mm is particularly suitable. Thermoplastic strips or bands can have a width of 2 to 10 mm, and at least part of one side of the tape should have a sticky or pressure sensitive adhesive coating, whereby the tape is temporarily attached to a surface of the joint Cloth area can be set - 8 -

According to another exemplary embodiment of the invention becomes part of a textile cloth as a car seat cover area held in a vertical jig. A piece of adhesive coated nylon sheet with a shape of the to The connection generating the connection thus forms a type of sealing sleeve and is applied to the cloth part and on this in the desired manner Position set. A second part held in another clamping frame is then pressed against the first part, including the adhesive or adhesive form. During the pressing, at least along the line of the connection Heat is applied, whereby the nylon sheet melts into the surfaces of both Tuc.hteile, which results in a very strong bond

It is also possible, for example, for the first cloth part to be horizontal align, in which case the adhering form is brought into position and held in this position by gravity until it is pressed so that no additional adhesive is used in this case. Again it is the use of an insensitive one or non-melting form for carrying the adhesive possible, in which case the adhesive can be bonded by hot pressing and then should be resistant to detergents and dry cleaning agents.

The portions of the bondable material can be preformed in any way to the shape desired. For example, if If a large batch of seat coverings is to be made, it is convenient to choose an appropriate number of pieces from it a suitable material such as nylon by injection molding.

Ideally, each piece is made as a separate shape for each joining process educated. However, a number of standard lengths and radii can be provided if desired, with a certain bond is achieved with an appropriate combination of these standard sizes.

The composition of the textile cloth to be connected is not critical, however, cloths made of a thermoplastic material with low- ' - 9 -

Generally not suitable for softening points. The inventive Process is particularly useful for natural fibers and especially for woolen cloths.

As opposed to temporarily setting the shaped piece (or of the pieces) made of adhesive material at the respective point before the Adhesive coating or gravity presses may alternatively be used as single spots of adhesive or, if the material is thermoplastic, it is a spot weld on the first part of the textile cloth. However, the molded piece must have a sufficient one for practical use Have strength so that it is not deformed, If it is only held in two or three places until -to be pressed.

While this form of invention is not believed to be greatest Find application in the manufacture of articles such as seat covers is, the embodiment is not limited and can be used in the Manufacture actually every textile article can be used.

A typical shaped piece for connecting two parts of textile cloth is shaped largely according to the line of the joint to be formed, has a thickness of up to 2 mm or more and one Width of up to 5 mm or more. The more material per unit of length of the molded piece, the stronger and less flexible the connection becomes.

The invention is described below with reference to the drawings on three embodiments of a distribution member for supplying coated with liquid adhesive Threads or yarns described. Show it:
