Description

Die Erfindung betrifft ein Verfahren zur Herstellung von wasserdichten Nähten an Kleidungsteilen, bei welchem zwischen die zu verbindenden Kleidungsteile ein Band im Bereich der vorgesehenen Naht gelegt wird und danach die Kleidungsteile miteinander vernäht werden.The invention relates to a process for the production of waterproof seams on clothing parts, in which a band is placed in the region of the intended seam between the clothing parts to be joined and then the clothing parts are sewn together.

Ein derartiges Verfahren ist beispielsweise aus EP 0 791 674 bekannt. Es wird dort ausgeführt, dass es eine übliche Arbeitsweise insbesondere bei wasserdichter und wasserdampfdurchlässiger Bekleidung ist, nach dem Vernähen der Kleidungsteile die entstandene Naht durch ein bei Hitze schmelzendes Klebeband abzudecken. In der Regel wird dies durch Aufbügeln des Klebebandes erreicht, wobei durch die Hitze des Bügeleisens der Kleber schmilzt und sich mit den beiden über die Naht verbundenen Kleidungsteilen verbindet und dabei die durch das Nähen entstandenen Öffnungen abdichtet.Such a method is for example off EP 0 791 674 known. It is stated there that it is a common way of working, in particular with waterproof and water-vapor-permeable clothing, to cover the seam produced by a heat-melting adhesive tape after the sewing of the clothing parts. In general, this is achieved by ironing the tape, wherein the heat of the iron melts the adhesive and connects to the two connected via the seam clothing parts, thereby sealing the resulting from sewing openings.

Gemäß EP 0 791 674 wird nun vorgeschlagen, zwischen die zu verbindenden Kleidungsteile in dem für die Naht vorgesehenen Bereich ein Band zu legen, welches nach dem Vernähen der Kleidungsteile und des Bandes durch Erhitzen zum Schmelzen gebracht wird, wodurch die durch die Naht entstandenen Öffnungen abgedichtet werden.According to EP 0 791 674 It is now proposed to lay a band between the clothing parts to be joined in the area provided for the seam, which is melted by heating after sewing the clothing parts and the band, whereby the openings formed by the seam are sealed.

Beide beschriebenen Verfahren führen zu dichten Nähten. Sie sind jedoch mit vielen Arbeitsschritten verbunden. Um die Teile, die mit einer Naht zu verbinden sind, zu fixieren, werden in der Regel zur Fixierung Klammern oder sogenannte Heftnähte angebracht, die nach dem Erzeugen der eigentlichen Naht wieder entfernt werden müssen.Both methods described lead to tight seams. However, they are associated with many steps. To join the parts with a seam are to fix, are usually for fixing brackets or so-called stitching attached, which must be removed after creating the actual seam again.

Insofern ist es Aufgabe der vorliegenden Erfindung die Herstellung von wasserdichten Nähten weiter zu vereinfachen.In this respect, it is an object of the present invention to further simplify the production of waterproof seams.

Die erfindungsgemäße Aufgabe wird bei einem Verfahren gemäß Oberbegriff des Anspruchs 1 dadurch gelöst, dass ein Band ausgewählt wird, welches beidseitig mit einer bei Raumtemperatur klebrigen Schicht versehen ist, wodurch die zu verbindenden Kleidungsteile vor dem Vernähen über das Band fixiert werden.The object of the invention is achieved in a method according to the preamble of claim 1, characterized in that a band is selected, which is provided on both sides with a sticky at room temperature layer, whereby the clothes to be joined are fixed before sewing on the tape.

Im Sinne der vorliegenden Erfindung umfasst der Begriff Kleidung nicht nur Kleidungsstücke wie Jacken, Hosen, Kleider, Anzüge und ähnliches sondern auch Kopfbedeckungen, Handschuhe und Schuhe, also alle Stücke, die den menschlichen Körper bedecken. Kleidungsteile sind hierbei die zugeschnittenen Teile, die miteinander verbunden, die fertige Kleidung bitden.For the purposes of the present invention, the term clothing includes not only garments such as jackets, pants, dresses, suits, and the like, but also headgear, gloves, and shoes, that is, any pieces that cover the human body. Clothing parts here are the cut parts that are joined together, the finished clothes bitden.

In einfachen Fällen, insbesondere wenn das verwendete Band aus elastischem Material besteht, ist eine nachfolgende Hitzebehandlung zum Schmelzen des Bandes gar nicht erforderlich, weil sich das Band sehr eng um das Nahtmaterial legt und somit bereits eine dichte Naht erreicht wird. Dies gilt insbesondere dann, wenn als Nahtmaterial ein Monofilamentfaden eingesetzt wird.In simple cases, especially if the band used is made of elastic material, a subsequent heat treatment for melting the band is not necessary because the band lays very tightly around the suture and thus already a dense seam is achieved. This applies in particular if a monofilament thread is used as the suture.

Dadurch dass ein Band ausgewählt wird, welches beidseitig mit einer bei Raumtemperatur klebrigen Schicht versehen ist, können die miteinander zu verbindenden Kleidungsteile in sehr einfacher Weise aufeinander fixiert werden, wobei es aber nicht mehr erforderlich ist, nach Erzeugung der Naht die Fixierung zu entfernen.Characterized in that a band is selected, which is provided on both sides with a sticky at room temperature layer, the clothes to be joined together can be fixed to each other in a very simple manner, but it is no longer necessary to remove after fixing the seam fixation.

Bevorzugt wird ein Band ausgewählt, welches aus einem bei Hitze schmelzendem Material besteht. Nach dem Vernähen wird das Band zumindest im Bereich der Naht zum Schmelzen gebracht, wodurch die durch die Naht entstandenen Öffnungen abgedichtet werden. Dies kann beispielsweise dadurch erreicht werden, dass die Nähte nach ihrer Herstellung bei einer zum Schmelzen des Bandes geeigneten Temperatur gebügelt werden.Preferably, a band is selected which consists of a heat-melting material. After sewing, the tape is melted at least in the area of the seam, thereby sealing the openings formed by the seam. This can be achieved, for example, by ironing the seams after their production at a temperature suitable for melting the strip.

Insbesondere, wenn bei dem erfindungsgemäßen Verfahren die Hitze über Hochfrequenz erzeugt wird, ist es möglich, sehr gezielt die Stellen des Bandes zum Schmelzen zu bringen, die zur Abdichtung der durch die Naht entstandenen Öffnungen notwendig sind.In particular, when the process of the present invention generates the heat by radio frequency, it is possible to melt very selectively the locations of the strip necessary to seal the openings formed by the seam.

Insbesondere bei Schuhen ist das erfindungsgemäße Verfahren zum Abdichten von Nähten besonders wirtschaftlich. Bei Schuhen, welche einen Außenschaft mit einem unteren Ende, einen Futterschaft mit einem unteren Ende, eine Brandsohle mit einer umlaufenden Kante und eine Sohle aufweisen, wobei das untere Ende des Außenschaftes, das untere Ende des Innenschaftes und die Außenkante der Brandsohle miteinander vernäht werden, zeichnet sich das erfindungsgemäße Verfahren dadurch aus, dass mit dem Band das untere Ende des Außenschaftes mit dem unteren Ende des Innenschaftes verbunden wird, bevor Außenschaft, Innenschaft und Brandsohle miteinander vernäht werden.Particularly in the case of shoes, the method according to the invention for sealing seams is particularly economical. For footwear having an outer skirt with a lower end, a lower end trim, an insole with a peripheral edge, and a sole, wherein the lower end of the outer skirt, the lower end of the inner skirt, and the outer edge of the insole are sewn together; the method according to the invention is characterized in that the tape, the lower end of the outer shaft is connected to the lower end of the inner shaft before the outer shaft, inner shaft and insole are sewn together.

Auch bei dieser Ausführungsform des erfindungsgemäßen Verfahrens hat es sich bestens bewährt, wenn ein Band ausgewählt wird, welches aus einem bei Hitze schmelzendem Material besteht. Nach Vernähen des Außenschaftes, des Futterschaftes und der Brandsohle, wird auf die Naht Hitze aufgebracht, wonach das Band schmilzt und die von der Naht erzeugten Öffnungen abdichtet.Also in this embodiment of the method according to the invention, it has proven to be best when a band is selected, which consists of a material melting in the heat. After suturing the outer shaft, lining and insole, heat is applied to the suture, after which the band melts and seals the openings created by the suture.

Dies gelingt in besonders einfacher Weise bei Schuhen mit angespritzter Sohle, weil in der Regel die Hitze der Schmelze, die nach dem Anspritzen das Sohlenmaterial bildet, ausreicht, um das zwischen Außenschaft und Futterschaft angeordnete und mit eingenähte Band zum Schmelzen zu bringen, wodurch die durch die Naht entstandenen Öffnungen abgedichtet werden.This is achieved in a particularly simple manner in shoes with molded soles, because usually the heat of the melt, which forms the sole material after injection, sufficient to between the outer shaft and feed shaft arranged to melt and sewn with tape, whereby the resulting from the seam openings are sealed.

Das erfindungsgemäße Verfahren gelingt vorzüglich bei Schuhen, die zwischen Außenschaft und Futter eine wasserdichte, wasserdampfdurchlässige Funktionsschicht aufweisen, die in der Regel mit dem Futter ein Laminat bildet. In diesem Falle wird bei dem erfindungemäßen Verfahren das Band zwischen die Außenschicht und die Funktionsschicht eingebracht, wodurch der die Funktionsschicht enthaltende Futterschaft mit dem Außenschaft bereits vor dem Vernähen fixiert ist.The inventive method is particularly successful in shoes that have between outer shaft and lining a waterproof, water vapor permeable functional layer, which usually forms a laminate with the lining. In this case, in the method according to the invention, the band is introduced between the outer layer and the functional layer, as a result of which the feed shank containing the functional layer with the outer sheath is already fixed prior to the sewing.
