Die Erfindung betrifft eine auf beiliegender Zeichnung in Fig. 1 bis 11 dargestellte Befestigungsweise von Randschutzschienen für die Balgfalten, durch welche die Anwendung möglichst dünner Pappe zu den Bälgen ermöglicht wird, wodurch die Bälge eine Geschmeidigkeit erhalten, die jede, auch die schwierigste und auf Instrumenten mit Bälgen von starker Pappe unausführbare Modulation der Töne gestattet.The invention relates to a method of fastening shown in FIGS. 1 to 11 in the accompanying drawing of edge protection rails for the bellows folds, which enable the use of the thinnest possible cardboard for the bellows which gives the bellows a suppleness that any, even the most difficult and On instruments with bellows made of strong cardboard, inexecutable modulation of the tones is permitted.
Um eine Verletzung der Balgpappe zu vermeiden, werden auf den Rändern der Balgfalten die Metallschienenhalter A in geeigneter Weise mittelst Leim oder Kitt befestigt. Diese Metallstreifenhalter sind mit den Schliefslappen a versehen, welche sich leicht umbiegen lassen. Die auf dem Balgrand befestigten Metallstreifenhalter werden mit einer Stoffschicht aus Zeug oder Leder so überklebt, dafs die Lappen a frei bleiben. Durch diese Herstellungsweise wird dem Balge trotz Verwendung dünner Pappe eine grofse Haltbarkeit verliehen.In order to avoid damaging the bellows cardboard, the metal rail holders A are fastened to the edges of the bellows folds in a suitable manner by means of glue or putty. These metal strip holder are provided with the lobe Schlief a, which are easy to bend. The metal strip holders attached to the edge of the bellows are glued over with a layer of cloth or leather in such a way that the flaps a remain free. This production method gives the bellows a great durability despite the use of thin cardboard.
Die Randschutzschienen bestehen aus schmalen, hohl geformten Metallblechstreifen B, die mit den Schlitzlöchern b versehen sind. Diese Metallblechstreifen werden um den Balgrand gelegt und die Lappen α durch die Schlitze b hindurchgebracht, worauf die Lappen nach beiden Seiten umgebogen werden, so dafs der Schutzstreifen fest auf den Rand des Balges geprefst wird.The edge protection rails consist of narrow, hollow-shaped sheet metal strips B, which are provided with the slotted holes b. These sheet metal strips are placed around the edge of the bellows and the tabs α are brought through the slots b , whereupon the tabs are bent over on both sides so that the protective strip is pressed firmly onto the edge of the bellows.
An den Verbindungsstellen der Metallstreifenenden werden besonders breite Lappen a\ Fig. ι bis 3, angewendet, welche die Stofsfuge genügend überdecken und das Aufbiegen der Enden verhindern.At the connection points of the metal strip ends, particularly wide flaps a \ Fig. 1 to 3 are used, which sufficiently cover the fabric joint and prevent the ends from bending open.
An Stelle der Schlitze in der Mitte der Beschlagstreifen können solche an den Seiten, wie b\ Fig. 8 bis 10, zeigt, angewendet werden, welche zur Aufnahme der Enden der Lappen dienen, die von der einen Seite des Beschlagstreifens nach der anderen gebogen werden, Fig. 10: Hierbei ist es nöthig, die Lappen nicht direct, sondern neben einander gegenüberstehend, Fig. 5, 8 und 10, anzuordnen. Bei einer derartigen Befestigung der Metallstreifen an den Balgrändern wird erzielt, dafs die Schutzschienen nur aus sehr schmalen Streifen gebildet zu sein brauchen, welche dem ganzen Balg eine grofse Stabilität verleihen und die Verwendbarkeit sehr schwacher Pappe gestatten, welche das Bewegen des Balges aufserordentlich erleichtert.In place of the slots in the middle of the mounting strip, there can on the sides, such as b \ Fig. 8 to 10, shows, be applied which serve for receiving the ends of the tabs, which are of the bent one side of the fitting strip after the other , Fig. 10: Here it is necessary not to arrange the flaps directly, but opposite one another, Figs. 5, 8 and 10. With such an attachment of the metal strips to the bellows edges it is achieved that the protective rails need only be formed from very narrow strips, which give the whole bellows great stability and allow the use of very weak cardboard, which greatly facilitates the movement of the bellows.
Die Metallstreifen selbst schützen nur die Ränder und beeinflussen die Beweglichkeit des Balges in keiner Weise.The metal strips themselves only protect the edges and affect the mobility of the Bellows in no way.
