PATENTAMT.PATENT OFFICE.
Nach dem durch Hauptpatent 200853 geschützten Verfahren sind zur Prüfung endlose Ringe oder Bänder erforderlich. Diesem Verfahren lag der Zweck zugrunde, das Einspannen oder Festklemmen der Enden der sonst verwendeten Streifen zu vermeiden. Nun können aber aus den· im Handel und in der Industrie vorkommenden Kautschukwaren ihrer Form wegen nicht immer Ring- oder endlose Bänder zum Prüfen entnommen werden. Gemäß der vorliegenden Erfindung sollen daher auch endliche Bänder geprüft werden können, bei denen aber ebenfalls ein Festklemmen der Enden nicht stattfindet.According to the procedure protected by the main patent 200853, there are endless possibilities for examination Rings or bands required. The purpose of this procedure was to clamp or to avoid jamming the ends of the otherwise used strips. Well can but from the rubber goods occurring in trade and industry, because of their shape, they are not always ring-shaped or endless Tapes are removed for testing. According to the present invention, therefore finite tapes can also be tested, but where there is also a jamming of the Ending does not take place.
Durch die Zeichnung wird die neue Einrichtung in beispielsweiser Anordnung veranschaulicht. The drawing illustrates the new facility in an exemplary arrangement.
Es sind h, ti drehbare Rollen, über welche der zu prüfende Materialstreifen m gelegt wird. Eine dieser Rollen, z. -B. h, steht mit einem Kraftmesser in Zusammenhang und ist mit dem Material des letzteren verschiebbar beweglich.There are h, ti rotatable rollers over which the material strip m to be tested is placed. One of these roles, e.g. -B. h, is associated with a dynamometer and is slidably movable with the material of the latter.
Es sind ferner die Rollen e, e' angeordnet, deren Achsen mit gleich großen Zahnrädern k, k' besetzt sind, welche in geeigneter Weise in Umdrehung versetzt werden können.There are also the rollers e, e ' arranged, the axes of which are equipped with gears k, k' of the same size, which can be set in rotation in a suitable manner.
Die Rollen e, β' sind mit Einrichtungen, z. B. einfachen Einlegeschlitzen s, versehen, vermittels welcher die Streifenenden festgelegt, jedoch nicht eingeklemmt werden.The roles e, β ' are equipped with devices such. B. simple insertion slots s, by means of which the strip ends are set, but not pinched.
Die Endteile des Prüfstreifens werden durchThe end parts of the test strip are through
*) Früheres Zusatzpatent 202450.*) Former additional patent 202450.
Drehung der Räder k, k' und Rollen e, e' auf letzteren aufgewickelt und hierbei der übrige Streifenteil bei gleichzeitiger Drehung der Halterollen h, ti, über letztere hinweglaufend, allmählich gedehnt. Diese allmählich zunehmende Dehnung äußert sich als zunehmende Spannung auf den mit einer der Rollen, z. B. h, verbundenen Kraftmesser, so daß das Prüfungsergebnis sichtbar gemacht und abgelesen werden kann.Rotation of the wheels k, k ' and rollers e, e' wound onto the latter and the remaining part of the strip is gradually stretched while simultaneously rotating the holding rollers h, ti, running over the latter. This gradually increasing elongation manifests itself as increasing tension on the one of the rollers, e.g. B. h, connected dynamometer, so that the test result can be made visible and read.
Um Kontrollprüfungen vornehmen zu können, kann man die Drehung der Räder k, k' bezüglich der Wickelrollen e, e' umkehren und die Spannung bezüglich die Bewegung des Prüfstreifens über Rollen h, ti in umgekehrter Richtung erfolgen lassen.In order to be able to carry out control tests, the rotation of the wheels k, k ' with respect to the winding rollers e, e' can be reversed and the tension with respect to the movement of the test strip can be carried out in the opposite direction via rollers h, ti.
Die Antriebseinrichtung der Wickelrollen e, e' sowie die Verbindung der Rollen h, ti mit dem Kraftmesser kann hierbei in verschiedener Weise gewählt und angeordnet werden.The drive device of the winding rollers e, e ' and the connection of the rollers h, ti with the dynamometer can be selected and arranged in various ways.
