Den Gegenstand der vorliegenden Erfindung bildet eine Backe zum ' Thermoschweissen oder zum Abkühlen von Materialien im allgemeinen, und insbesondere von thermoplastischen Materialien, welche auch eine nicht gleichförmige oder, wie dem auch sei, eine unregelmässige Wandstärke besitzen können. Die Backe nach der vorliegenden Erfindung ist dadurch gekennzeichnet, dass die Oberflächen der erhitzenden oder abkühlenden Körper, die mit den zu schweissenden oder abzukühlenden Teilen in direkte Berührung gelangen, automatisch verformbar sind, so dass sie sich in der Lage befinden, sämtlichen Unregelmässigkeiten des Profils der betreffenden Teile selbst zu d folgen.The subject of the present invention is a jaw for the thermal welding or cooling of materials in general, and in particular thermoplastic materials, which can also have a non-uniform or, however, an irregular wall thickness. The jaw according to the present invention is characterized in that the surfaces of the heating or cooling bodies that come into direct contact with the parts to be welded or cooled are automatically deformable so that they are able to deal with all irregularities in the profile of the relevant parts themselves to follow d.

Die vorliegende Erfindung ermöglicht insbesondere, einen schwerwiegenden Nachteil zu beseitigen, der sich bei der Herstellung kleiner und aus (thermoplastischem) Kunststoff bestehender Säcke ergibt· In diesem Falle geht man vorzugsweise von einem rohr- oder schlauchförmigen Band«aus, das man in ^ebereinstimmung mit den Rändern nach innen umbiegt, so dass zwei V-förmige Einbuchtungen entstehen, wodurch sich das Fassungsvermögen des kleinen Sackes selbst, sobald er gefüllt wird, erhöht und eine genügend grosse Auf-In particular, the present invention enables a serious To eliminate the disadvantage that arises in the production of small bags made of (thermoplastic) plastic results · In this case it is preferable to use a pipe or tubular tape ", which is made in accordance with the The edges are bent inwards so that two V-shaped indentations are created, which increases the capacity of the small sack itself, as soon as it is filled, and a sufficiently large volume

lagefläche oder Standfläche für den genannten Sack erhalten wird» Daraus folgt, dass während der Schweissung der gesamten Breit© des flach gedrückten Rohres oder Schlauches die beiden V-förmig nach innen umgebogenen Ränder merklich holier liegen als die mittleren Teile des kleinen Sackes, weshalb sich bei Verwendung der normalen Thermoschweissbacken, bei denen die oberflächen der erhitzenden Körper starr sind, eine übermässige Scfoweissung ergibt, anders gesagt, wird dort die Schweissung in Uebereinstiminung Mi*--cion-Etändexn mit den Rändern mit einem zu starken Druck ausgeführt, während sie in Uebereinstinunung mit dem mittleren Teil des kleinen Sackes ungenügend ist und in den zwischen diesen beiden genannten -Teilen gelegenen Zonen auf Grund des fehlendem Druckes eventuell auch kein© Schweissung erfolgen kann, wodurch sich Verluste des Inhaltes des kleinen Sackes, ergeben -können, und swar νοτ allem dann, wenn der genannte Inhalt flüssig ist»surface or standing area for the said sack is obtained »It follows that during the welding of the entire width © of the flattened pipe or hose, the two V-shaped inwardly bent edges are noticeably closer than the middle parts of the small sack, which is why Use of normal thermal welding jaws, in which the surfaces of the heating body are rigid, results in excessive scfoweissung, in other words, the welding is carried out in accordance with Mi * - cion-Etändexn with the edges with too much pressure, while they are in accordance with the middle part of the small sack is inadequate and in the zones between these two mentioned parts, due to the lack of pressure, welding may not be possible, which can result in losses of the contents of the small sack, and everything else then, when the said content is liquid »

Die Thermoschweiss- oder Kühlbacke nach der vorliegenden Erfindung beseitigt diesen Nachteil, da sicfe öio Oberflächen der erhitzenden Körper, welche die genannte Backe bilden, während der Ausübung das Druckes elastisch verformen und aoitoiBatisels die Form des, zu schweissenden (bzw· abzukühlenden) Materials annehmen, wenn sie ihren Druck auf dasselbe ausüben, indesi sie sich santt^chen vornaaderaen WandstärkenunterscliiedenL und Unregelmässigkeiten anpassen, und ihnen folgen.The thermal welding or cooling jaw according to the present invention eliminates this disadvantage, since it sicfe oio surfaces of the heating Bodies that form the said cheek, while exercising the Pressure deform elastically and aoitoiBatisels the shape of the, too to be welded (or to be cooled) if they exert their pressure on the same while they are santt ^ chen vornaaderaen Adjust wall thickness differences and irregularities, and follow them.
