  DISPOSITIF POUR LE SOUDAGE DE PLAQUES THERMOPLASTIQUES. 



   La présente invention se rapporte à un dispositif pour le soudage bout à bout de plaques en matériau thermoplastique, par exemple en polyéthylène, en employant un bâton de soudure continu et déjà liquéfié. 



   Dans la technique du soudage d'éléments en matériau thermo- plastique, le problème qui se pose toujours est celui du soudage intime de deux plaques posées l'une à côté de   l'autre    Il s'ajoute encore la dif- ficulté supplémentaire que ces plaques ne sont en général   atteignables   que d'un côté seulement, car elles servent souvent de recouvrement inter- ne pour les récipients les plus divers. 



   Il est bien connu d'employer un dispositif de soudage, qui dirige au moyen   d'une   tuyère, de l'air chaud ou un gaz chaud sur la coutu- re. En employant alors un bâton de soudure du même matériau que les plaques, on les soude l'une à l'autre par leurs arêtes. Ceci peut se faire éventuelle- ment en exerçant encore une pression sur les plaques au moyen d'un galet. 



   En comparaison avec ces appareils connus, le dispositif selon l'invention pour le soudage frontal de plaques thermoplastiques est de construction simple, est très maniable et ne   requiert   aucun courant d'air chaud. 



   Le dispositif selon l'invention est caractérisé par un organe de soudage présentant un patin destiné-à glisser sur les bords des plaques à souder, ce patin présentant une saillie longitudinale passant entre lesdits bords., des moyens pour chauffer ce patin et cette saillie et par là ces bords., le patin présentant encore un évidement dans lequel on enfile un bâton de soudure., qui ressort   liquéfié   entre lea bords des plaques. 



   Le dessin annexé représente, à titre non limitatif, un 

 <Desc/Clms Page number 2> 

 mode d'exécution de l'objet de l'invention. 



   La fig. 1 est une vue partiellement en coupe du dispositif. 



   La fig. 2 est une vue de face de l'organe de soudage. 



   La poignée 1, en bois ou en un autre matériau isolant appro- prié, présente un évidement axial, dans lequel passe un câble électrique 2. Une douille 3 est montée sur la poignée 1 et porte à son extrémité une plaque   4.   Cette dernière présente sur sa face tournée vers la poignée 1, une prise de contact 5. La plaque 4 est fixée à une plaque 7 au moyen de boulons 6, de façon qu'entre ces deux plaques un espace libre 8 serve d'isolant et protège la main tenant la poignée contre les brûlures. La plaque 7 est sou- dée à un récipient 9 en matériau conducteur de chaleur, et contient l'élé- ment électrique de chauffe 10. Une enveloppe isolatrice 11 entoure le ré- cipient 9. Deux câbles 12,13 relient les pôles de l'élément 10 à la prise   5.   laquelle est connectée au câble 2.

   Cette prise 5 permet de remplacer rapidement l'élément 10 par un autre. L'organe de soudage 14 est monté dans un évidement de la partie inférieure du récipient 9, il y èst fixé par une vis de réglage 15. Il peut pivoter dans cet évidement et être fi- xé dans n'importe quelle position. 



  Il présente un patin 16, ayant une surface de chauffe 16a et une saillie longitudinale 17 sur cette surface 16a. Cette saillie s'étend de l'extré- mité antérieure du patin 16 jusou'à environ son milieu. Ce patin 16 présen- te de plus un évidement 18 passant au dessus de la saillie 17 et aboutissant juste derrière elle en 21 à la surface 16a du patin 16. On procède avec le dispositif décrit de la façon suivante: Les deux plaques 19 et 20 à souder, en matériau thermoplastique, sont posées l'une à côté de l'autre (fig.2) sur un support quelconque, de façon à ne laisser entre leurs arêtes qu'un espace correspondant à l'épaisseur de la saillie 17. Lorsque le dispositif sert à souder des plaques ayant toujours la même épaisseur, on donnera à la saillie 17 une hauteur au-dessus de la surface 16a correspondant à l'épais- seur des plaques.

   On applique alors le dispositif sur les plaques de façon que la saillie 17 passe entre elles, cependant que la surface de chauffe 16a repose sur les bords des plaques 19 et 20. La chaleur engendrée par l' élément 10, se transmet par le récipient conducteur 9, à l'organe de sou- dage, c'est-à-dire à la surface 16a et à la saillie 17. Celles-ci chauffent les bords des plaques jusqu'à ce qu'ils se liquéfient. 



  On promène alors le dispositif, la saillie 17 restant toujours entre les plaques. En même temps on pousse le bâton de soudure dans l'évidement 18 et il ressort liquéfié par l'orifice 21 entre les bords chauds des pla- ques 19 et 20.

  DEVICE FOR WELDING THERMOPLASTIC PLATES.



   The present invention relates to a device for the butt welding of plates made of thermoplastic material, for example polyethylene, by using a continuous and already liquefied welding stick.



   In the technique of welding elements of thermoplastic material, the problem which always arises is that of the intimate welding of two plates placed one next to the other. There is also the additional difficulty that these The plates are usually only accessible from one side, as they often serve as an internal cover for a wide variety of containers.



   It is well known to employ a welding device which directs hot air or hot gas onto the seam by means of a nozzle. By then using a welding stick of the same material as the plates, they are welded to each other by their edges. This can be done if necessary by exerting further pressure on the plates by means of a roller.



   In comparison with these known devices, the device according to the invention for the frontal welding of thermoplastic plates is of simple construction, is very handy and does not require any current of hot air.



   The device according to the invention is characterized by a welding member having a shoe intended to slide on the edges of the plates to be welded, this shoe having a longitudinal projection passing between said edges., Means for heating this shoe and this projection and thereby these edges., the pad still having a recess in which a solder stick is threaded, which emerges liquefied between the edges of the plates.



   The appended drawing represents, without limitation, a

 <Desc / Clms Page number 2>

 embodiment of the object of the invention.



   Fig. 1 is a partially sectional view of the device.



   Fig. 2 is a front view of the welding member.



   The handle 1, made of wood or another suitable insulating material, has an axial recess, through which passes an electric cable 2. A socket 3 is mounted on the handle 1 and carries at its end a plate 4. The latter has on its face facing the handle 1, a contact socket 5. The plate 4 is fixed to a plate 7 by means of bolts 6, so that between these two plates a free space 8 serves as an insulation and protects the hand holding the handle against burns. The plate 7 is welded to a receptacle 9 made of a heat-conducting material, and contains the electric heating element 10. An insulating casing 11 surrounds the receptacle 9. Two cables 12, 13 connect the poles of the 'item 10 to socket 5. which is connected to cable 2.

   This socket 5 enables element 10 to be quickly replaced by another. The welding member 14 is mounted in a recess in the lower part of the container 9, it is fixed there by an adjusting screw 15. It can pivot in this recess and be fixed in any position.



  It has a pad 16, having a heating surface 16a and a longitudinal projection 17 on this surface 16a. This projection extends from the anterior end of the pad 16 to about its middle. This pad 16 also has a recess 18 passing above the projection 17 and terminating just behind it at 21 at the surface 16a of the pad 16. The device described is carried out as follows: The two plates 19 and 20 to be welded, made of thermoplastic material, are placed one next to the other (fig. 2) on any support, so as to leave between their edges only a space corresponding to the thickness of the projection 17. When the device is used to weld plates always having the same thickness, the projection 17 will be given a height above the surface 16a corresponding to the thickness of the plates.

   The device is then applied to the plates so that the projection 17 passes between them, while the heating surface 16a rests on the edges of the plates 19 and 20. The heat generated by the element 10 is transmitted through the conductive container. 9, to the welder, that is to say to the surface 16a and to the projection 17. These heat the edges of the plates until they liquefy.



  The device is then moved, the projection 17 still remaining between the plates. At the same time, the solder stick is pushed into the recess 18 and it emerges liquefied through the orifice 21 between the hot edges of the plates 19 and 20.



   RESELL I CATIONS.



   1. Device for welding plates of thermoplastic material, characterized by a welding member having a shoe intended to slide on the edges of the plates to be welded, this shoe having a longitudinal projection passing between said edges, and by means for heating this pad and this projection and thereby these edges.
