Description
Verfahren und Vorrichtung zur Herstellung von Netzen aus thermoplastischem Kunststoff Zur Herstellung von Netzen aus Kunststoff ist es bekannt, auf ein umlaufendes endloses Band Kunststoffäden in lösungsmittelhaltigem und daher noch klebefähigem Zustand auflaufen zu lassen und dabei dem Band gleichzeitig in seiner Querrichtung eine solche hin- und hergehende Bewegung zu erteilen, daß sich die Kunststoffäden in Form sich berührender Wellenlinien auf dem Band ablagern. Die einzelnen Fäden verkleben dabei an ihren Berührungsstellen, und es entsteht so ein Netz, das nach dem Trocknen der Fäden von dem Band abgezogen werden kann. Method and device for the production of nets from thermoplastic Plastic For the production of nets from plastic, it is known to use a circumferential endless band of plastic threads in solvent-based and therefore still adhesive State to run up and thereby the tape at the same time in its transverse direction to give such a reciprocating motion that the plastic threads deposited in the form of touching wavy lines on the belt. The individual threads stick together at their points of contact, creating a network that follows can be peeled off the tape as the threads dry.
Nach einem anderen bekannten Verfahren wird thermoplastischer Kunststoff in eine entsprechend profilierte beheizte Walze eingestrichen.ulxd das so gebildete Netz durch eine glatte Walze abgezogen. Another known method is thermoplastic plastic brushed into a suitably profiled heated roller. ulxd the so formed Net pulled off by a smooth roller.
Nach der Erfindung werden zur Herstellung eines Netzes aus thermoplastischem Kunststoff, beispielsweise aus Polyvinylchlorid, Polyäthylen, Polyamid od. dgl., die einzeInen Fäden des Netzes gemeinsam durch Strangpressen erzeugt und hierbei gleichzeitig im Strangpreßvorgang die Kreuzungsstellen des Netzes gebildet. Der Kunststoff verläßt daher die Düse der Strangpresse als fertiges Netz. Die Erfindung ermöglicht es somit, durch Strangpressen unmittelbar, d. h. ohne Zuhilfenahme zusätzlicher Arbeitsgänge, Netze herzustellen. According to the invention are used to produce a network of thermoplastic Plastic, for example made of polyvinyl chloride, polyethylene, polyamide or the like., the individual threads of the network are produced together by extrusion and here at the same time formed the intersections of the network in the extrusion process. Of the Plastic therefore leaves the extruder nozzle as a finished network. The invention thus makes it possible, by extrusion, directly, i. H. without the help of additional Operations to produce networks.
Die Strangpresse für die Durchführung des Verfahrens nach der Erfindung unterscheidet sich von den bekannten Strangpressen im wesentlichen dadurch, daß ihre Preßdüse Idurch zwei sich längs einer Mantellinie berührende umlaufende Walzen gebildet wird, die an ihren Oberflächen mit sich kreuzenden Nuten für die Erzeugung des Netzes versehen sind. Dabei bilden jeweils diese Nuten in der Berührungszone der beiden Walzen eine Reihe von einzelnen Düsen, aus denen beim Preßvorgang die Fäden des Netzes austreten. Weiterhin werden dabei jedesmal, wenn beim Umlauf der Walzen die Nuten sich in der Berührungszone kreuzen oder Kreuzungsstellen der Nuten die Berührungszone passieren, Kreuzungsstellen der Fäden des Netzes gebildet. The extruder for carrying out the method according to the invention differs from the known extrusion presses essentially in that its press nozzle I by two rotating rollers touching along a surface line is formed on their surfaces with intersecting grooves for generating of the network are provided. In each case, these grooves form in the contact zone the two rollers a number of individual nozzles, from which the pressing process Threads of the net emerge. Furthermore, every time the Roll the grooves cross in the contact zone or intersection points of the grooves pass the contact zone, crossing points of the threads of the network are formed.
Eine Vorrichtung für die Durchführung des Verfahrens nach der Erfindung ist in Fig. 1 im Längsschnitt und in Fig. 2 in der Vorderansicht schematisch dargestellt. Die Fig. 3 bis 8 zeigen einige Ausführungsformen des die Preßdüsen bildenden Walzen paares sowie die erzeugten Netze. An apparatus for carrying out the method according to the invention is shown schematically in Fig. 1 in longitudinal section and in Fig. 2 in the front view. 3 to 8 show some embodiments of the roller forming the press nozzles Paares as well as the generated networks.
In den Fig. 1 und 2 bezeichnet 1 das Gehäuse der Strangpresse mit der Förderschnecke 2 für den thermoplastischen Kunststoff und 3 den Spritzkopf. In Figs. 1 and 2, 1 denotes the housing of the extruder with the screw conveyor 2 for the thermoplastic material and 3 the injection head.
Dieser enthält auf seiner Austrittsseite in dem Rahmea4 die gegenläufig umlaufenden Walzen 5 und 6) die in ihrer Berührungszone 7 die Düse der Strangpresse bilden. Die Walzen 5 und 6 stehen mittels der Zahnräder 8 und 9 miteinander im Eingriff und werden durch das mit einem dieser Zahnräder käramende Zahnrad 10 angetrieben. Mit 11 sind Heizkanäle des Rahmens 4 bezeichnet, die mittels der Rohre 12 gespeist werden. Die beiden Walzen 5 und 6 können zur Enzeugung der Netze in verschiedener Weise mit sich kreuzenden Nuten versehen sein.This contains the opposite directions on its exit side in the frame a4 rotating rollers 5 and 6) which in their contact zone 7 the nozzle of the extrusion press form. The rollers 5 and 6 are by means of the Gears 8 and 9 mesh with one another and are driven by the gear 10 meshing with one of these gears. Heating channels of the frame 4, which are fed by means of the tubes 12, are designated by 11 will. The two rollers 5 and 6 can be used to generate the networks in different Way be provided with intersecting grooves.
Nach Fig. 3 sind nur in Idie Oberfläche der Walze 5 Nuten eingearbeitet, während die Walze 6 glatt ausgebildet ist. Die Walze 5 enthält zwei sich kreuzende Reihen paralleler Nuten 13 und 14. Das erzeugte Netz ist in Fig. 4 dargestellt. According to Fig. 3 5 grooves are only incorporated in the surface of the roller, while the roller 6 is smooth. The roller 5 contains two intersecting Rows of parallel grooves 13 and 14. The mesh produced is shown in FIG.
Nach den Fig. 5 und 7 sind beilde Walzen mit Nuten versehen. According to FIGS. 5 and 7, both rollers are grooved.
Bei der in Fig. 5 dargestellten Anordnung sind in die Walze 5 parallele Nuten 15 entsprechend der einen Fadenrichtung und in die Walze 6 parallele Nuten 16 entsprechend der anderen Fadenrichtung des Netzes eingearbeitet, so daß die Nuten dieser beiden Walzen sich in der Berührungszone der Walzen kreuzen. Dabei verlaufen in dem Beispiel Idie Nuten 16 in I,ängsrichtung Ider Walze und die Nuten 15 senkrecht dazu. Das erzeugte Netz zeigt Fig. 6. In the arrangement shown in Fig. 5 are parallel in the roller 5 Grooves 15 corresponding to the one thread direction and in the roller 6 parallel grooves 16 incorporated according to the other thread direction of the network, so that the grooves these two rollers intersect in the contact zone of the rollers. In doing so, run in the example I the grooves 16 in I, longitudinal direction I of the roller and the grooves 15 perpendicular to. The generated network is shown in FIG. 6.
Es können aber auch beide Walzen mit schrägverlaufenden Nuten versehen sein.However, it is also possible for both rollers to be provided with inclined grooves be.
Nach Fig.7 enthält jede (der Walzen zwei sich kreuzende Reihen von Nuten, und zwar sind die Nuten 17 und 18 der Walze 5 gegenüber den Nuten 19 und 20 der Walze 6 jeweils um eine halbe Kreuzungsweite versetzt angeordnet. Jede der Walzen erzeugt beim Preßvorgang in der Berührungszone jeweils mit den glatten Oberflächenteilen der anderen Walze ein Netz, und,diese einzelnen Netze vereinigen sich schon bei ihrer Entstehung an den Kreuzungsstellen der Nuten beider Walzen zu einem einzigen Netz, das in Fig. 8 dargestellt ist. According to Figure 7, each (of the rollers contains two intersecting rows of Grooves, namely the grooves 17 and 18 of the roller 5 opposite the grooves 19 and 20 of the roller 6 are each arranged offset by half a crossing width. Each of the Rolling generated during the pressing process in the contact zone with the smooth surface parts the other roller is a network, and, these individual networks already unite at their emergence at the intersection of the grooves of both rollers into a single one Network shown in FIG.
Die erfindungsgemäß hergestellten Netze lassen sich für die verschiedensten Zwecke verwenden. The nets produced according to the invention can be used for the most varied Purposes.
