Description
Verfahren zum Befestigen von örtlich begrenzten, ganz oder teilweise aus warmformbaren Kunststoffen bestehenden Verstärkungsstücken auf Stoffbahnen Die Erfindung bezieht sich auf die Befestigung von vorgeschnittenen Formstücken, die ganz oder teilweise aus warmformbaren Kunststoffen bestehen, auf Stoffbahnen oder Stoffstücken aus dem gleichen NVerk stoff. Solche Verstärkungen verwendet man, um ein Ausreißen des Stoffes an Stellen von Stoffstüclken, beispielsweise Kleidungsstücken od. dgl., zu verhindern, wo Haken, Ösen, Patentknöpfe, Nähte od. dgl. angesetzt oderbaschen, Bänder, Schnallen, Knöpfe, Ringe od. dgl. angefällt oder schließlich Knopflöcher, Schnürlöcher od. dgl. eingenäht werden sollen.Method of fastening localized, in whole or in part Reinforcing pieces made of thermoformable plastics on lengths of fabric the Invention relates to the attachment of pre-cut fittings that consist entirely or partially of thermoformable plastics, on sheets of fabric or Pieces of fabric made from the same N material. Such reinforcements are used to tearing of the fabric in places of pieces of fabric, for example items of clothing or the like. To prevent where hooks, eyes, patent buttons, seams or the like orbaschen, ribbons, buckles, buttons, rings or the like. Accrued or finally Buttonholes, lace holes or the like are to be sewn.
Die sachgemäße Befestigung derartiger vorgeschnittener Verstärkungsstücke an den Stoffbahnell macht erhebliche Schwierigkeiten, die nach den bisherigen Methoden schwer zu überwinden waren. Proper attachment of such pre-cut reinforcement pieces to the Stoffbahnell makes considerable difficulties, according to the previous methods were difficult to overcome.
Zweck der Erfindung ist daher, diese Mängel und Schwierigkeiten zu überwinden und vor allem die maschinelle Durcliführung dieser Arbeit zu ermöglichen. Unter gane oder teilweise aus warmformbaren Kunststoffen bestehenden Stoffbahnen oder Stofflwerkstücken sind im Sinne der Erfindung solche zu verstehen, die sich zufolge ihres Gehalts an warmformharen Kunststoffen dazu eignen, durch Erwärmen und darauffolgendes Zusammendrücken der einander zugekehrten Oberflächen miteinander verschweißt zu werden. Insonderheit kommen hier vorgeschnittene Verstärkungsstücke klei- neren Umfangs aus einem mit einem warmformbaren Kunststoff überzogenen Gewebe in Frage, die auf sogenannten trägerlosen Folien aus warmformbarem Kunststoff befestigt werden sollen. The purpose of the invention is therefore to address these shortcomings and difficulties overcome and, above all, enable the machine to carry out this work. Under whole or partially made of thermoformable plastics or material workpieces are to be understood in the context of the invention, which due to their content of thermoformed plastics, they can be heated by heating and then compressing the facing surfaces together to be welded. In particular, there are pre-cut reinforcement pieces small inner scope made of a with a thermoformable plastic coated fabric in question, which is based on so-called carrierless films made of thermoformable Plastic should be attached.
Derartige Verstärkungen wurden unter gleichartigen Vorbedingungen bisher entweder nur lose untergelegt oder lose eingenäht oder aufgeklebt oder im Bügelvenfahren aufgeschweißt. Diese Verfahren hatten folgende Nachteile: Bei losem Unterlegen der Verstärkung wird die Einreiß- bzw. Ausschlupfgefahr nicht unterbunden. Beim Aufkleben trennt sich die Verstärkung sehr leicht von der Stoffbahn infolge Ausdehnung unter Zug, da das Klebemittel sich meist gar nicht oder unzureichend mitdehnt. Beim Anschweißen im Bügelverfahren muß die Hitze mindestens eine der aufeinandergelegten Stoffdicken durchdringen, um die in Berührung stehenden Oberflächen zwecks inniger Verbindung zum Schmelzen zu bringen. Dabei ist es außerordentlich schwierig, die richtige Beheizungsdauer und den richtigen Druck zu ermitteln. Etwas zu wenig Hitze und' Drudk läßt keine Verbindung entstehen, und eine Kleinigkeit zuviel verschwächt die Stoffbahn an den Rändern zu sehr. Außerdem kann bei Verstärkungen mit Gewebeunterlage der geschmolzene warmformbare Kunststoff leicht durch die Gewebeschicht durchschlagen und die Verstärkung hart und unschön machen. Such reinforcements were made under similar preconditions so far either only loosely underlaid or loosely sewn or glued on or in Welded on bracket vents. These methods had the following disadvantages: With loose Placing the reinforcement underneath does not prevent the risk of tearing or slipping. When glued on, the reinforcement separates very easily from the fabric as a result Expansion under tension, as the adhesive usually does not work at all or is inadequate also stretches. When welding by ironing, the heat must be at least one of the superimposed Thicknesses of fabric penetrate to the surfaces in contact in order to be more intimate Bringing the connection to melt. It is extremely difficult to do this to determine the correct heating time and pressure. A little too little heat and 'Drudk makes no connection, and a little too much weakens the length of the fabric too much at the edges. It can also be used for reinforcements with a fabric backing the melted thermoformable plastic easily pierce through the fabric layer and make the reinforcement hard and ugly.
Es wurde nun gefunden, daß diese Mißstände nur dadurch mit Sicherheit vermieden werden können, wenn man die einander zugekehrten Flächen mittels eines genügend breiten Heizkörpers an der oberen Schicht zum Schmelzen bringt und gleichzeitig die beiden Teile (StofFbahn undVerstärkungsstück) gegeneinanderdrückt. It has now been found that these grievances are only certain with certainty can be avoided if the facing surfaces by means of a sufficiently wide radiator melts on the upper layer and at the same time presses the two parts (fabric and reinforcement piece) against each other.
Es besteht nun ein wesentliches Interesse daran, diese Arbeitsweise maschinell durchzuführen, da die bisher von Hand ausgeübte Befestigung solcher Verstärkungsstücke außerordentlich zeitraubend und unbequem ist. Hierbei soll in erster Linie eine Nahtschweißmaschine verwendet werden, bei der ein vorzugsweise keilförmiger Heizkörper in den an der Zuführungsseite von zwei elastisch gegeneinandergepreßten Druckwalzen zwischen ihnen gebildeten keilförmigen Spalt vorsteht. There is now an essential interest in this way of working to be carried out by machine, since the fastening of such reinforcing pieces, which was previously carried out by hand is extremely time consuming and inconvenient. Primarily a Seam welding machine can be used in which a preferably wedge-shaped heating element in the pressure rollers that are elastically pressed against one another on the feed side wedge-shaped gap formed between them protrudes.
Die maschinelle Durchführung der beabsichtigten Arbeit, insonderheit durch stetiges Durchführen des Werkstücks durch die Nahtbildestelle der erwähnten Maschine, stößt hauptsächlich wegen der Kleinheit der zu befestigenden vorgeschnittenen Formstücke, die meist runde, ovale oder rechteckige Flecken darstellen, auf Schwierigkeiten. The mechanical execution of the intended work, in particular by continuously passing the workpiece through the seam formation site of the mentioned Machine butts mainly because of the small size of the pre-cut to be attached Form pieces, which are mostly round, oval or rectangular spots, face difficulties.
Um diese Schwierigkeiten zu beseitigen, sollen nach der Erfindung die zur Verstärkung dienenden Formstücke mit der meist aus Gewebe bestehenden Rückseite auf einem aus einem mit warmformbarem Kunststoff nicht verschweißbaren Werkstoff bestehenden Träger, z. B. einem Zellophanstreifen von hinreichender Länge, lösbar, z. B. durch Kleben, befestigt werden, worauf man das Stofformstück mit dem daraufgelegten Zellophanstreifen durch die Nahtbildestelle der Nahtscbweißmaschine hindurchführt, wodurch ein oberflächiges Verschweißen der Verstärkungsstücke mit der Stoffbahn an der gewünschten Stelle erfolgt. Hierauf kann der als Träger dienende Zellophanstreifen mit leichter Mühe abgezogen werden, während die Verstärkungsfiecken, mit dem Werkstück fest verschweißt, auf diesem haftenbleiben. In order to overcome these difficulties, according to the invention the reinforcement shaped pieces with the back side, which is mostly made of fabric on a material that cannot be welded to thermoformable plastic existing carrier, e.g. B. a cellophane strip of sufficient length, detachable, z. B. by gluing, are attached, whereupon the Stofformstück with the placed on it Passes the cellophane strip through the seam formation point of the seam sealing machine, whereby a surface welding of the reinforcement pieces with the fabric web takes place at the desired location. The cellophane strip serving as a carrier can then be used can be peeled off with ease while the reinforcement pegs are attached to the workpiece firmly welded to stick to this.
Ein Ausführungslbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt: es zeigt Abb. I die Nahtbildestelle der Schweißmaschine ohne Werkstück mit ausgeschwenktem Heizkörper und einem Zellophanstreifen mit aufgeklebten Verstärkungsstücken, Abb. 2 die Nahtsbildestelle mit Werkstück und Heizkörper in der Arbeitsstellung. An exemplary embodiment of the subject matter of the invention is shown in the drawing shown: Fig. I shows the seam formation point of the welding machine without a workpiece with swiveled out radiator and a cellophane strip with stuck on reinforcement pieces, Fig. 2 the seam formation point with workpiece and heating element in the working position.
I ist die obere und 2 die untere Rolle, 3 der Heizkörper mit breitem ,keilförmigem Fußende 4. Der Zellophanstreifen 5 trägt in leicht lösbarer Verbindung die Verstärkungsstücke 6, 7, die auf die Stoffbahn § aufgeschweißt werden sollen. Nach Beendigung des Schweißvorgangs wird der Zellophanstreifen 5 von den Verstärkungsstücken 6, 7 abgezogen. I is the top roller and 2 the bottom roller, 3 the radiator with wide , wedge-shaped foot end 4. The cellophane strip 5 carries in an easily detachable connection the reinforcement pieces 6, 7, which are to be welded onto the web of fabric §. After completion of the welding process, the cellophane strip 5 is removed from the reinforcement pieces 6, 7 deducted.
