Description

Einrichtung zum Festhalten von Papier oder Metallfolie, Pflanzenblättern, Fasern, Staub u. dgl. auf Arbeitsgeräten, beispielsweise Druckmaschinen Bei Papierverarbeitungsmaschinen, wie Druckmaschinen und Sc'tmeidemasch:tnen, sowie bei Papierbogenfördervorrichtungen sind zum Festhalten des zu verarbeitenden Papiers meist Greifer, Saugluft oder derartige mechanische Vorrichtungen vorgesehen.Device for holding paper or metal foil, plant leaves, Fibers, dust and the like on work equipment, e.g. printing machines In paper processing machines, such as printing machines and sc'tmeidemasch: tnen, as well as paper sheet conveyors are usually grippers, suction air or similar to hold the paper to be processed mechanical devices provided.

Die Erfindung bezweckt, die Anbringung derartiger mechanischer Vorrichtungen auszuschalten und auf einfache Art die Eigenschaft von Acetylcellulosefolien, durch Reibung elektrisch zu werden und Papier, Metall, trockene Pflanzenblätter, ganz kleine Papier- oder sonstige Ausschnitte, ja sogar Staub anzuziehen, nützlich zu machen. Als Beispiel hierfür wird eine Druckmaschipe angeführt, deren Druckzylinder mit Acetylcellulose überzogen ist. Dessen Fläche wird bei seiner Umdrehung durch Reibung elektrisch gemacht, wodurch das mitgenommene Papier an dem Druckzylinder an jeder Stelle festgehalten wird.The invention aims to provide such mechanical devices to switch off and in a simple way the property of acetyl cellulose films Friction to become electric and paper, metal, dry plant leaves, whole small paper or other cutouts, even to attract dust, useful too do. As an example of this, a printing machine is given, its printing cylinder is coated with acetyl cellulose. Its surface is through its rotation Friction made electric, causing the dragged paper to stick to the impression cylinder is recorded at every point.

Bei Förderbändern wird die Tragfläche des Bandes mit Acetylcellulose überzogen, wodurch erzielt wird, daß die auf dem Förderband anliegenden Arbeitsstücke nicht abrutschen können, sondern festgehalten werden. Das gleiche geschieht auch z. B. bei Schneidemaschinen u. dgl. Auf diese Weise können auch äußerst kleine Stückchen der vorerwähnten Stoffe festgehalten werden. Es hat sich auch gezeigt, daß z. B. Staub an einem derartigen Förderband haften bleibt, so daß dieses sogar zum Entstauben von Tabakverarbeitungsmaschinen geeignet ist.In the case of conveyor belts, the supporting surface of the belt is made of acetyl cellulose coated, whereby it is achieved that the work pieces resting on the conveyor belt cannot slip off, but be held on. The same thing also happens z. B. in cutting machines and the like. In this way, even extremely small pieces of the aforementioned substances are recorded. It has also been shown that, for. B. Dust adheres to such a conveyor belt, so that this even for dedusting of tobacco processing machines is suitable.

An sich ist es bekannt, durch elektrisch erregte Hartgummiplatten Gase von Staub zu reinigen; fluch. ist es nicht neu, umlaufende Bänder mit Reibungselektrizität zu laden., um eine Papierbahn an den umlaufenden Bändern festzuhalten.It is known per se by electrically excited hard rubber plates To purify gases from dust; curse. it is not new, revolving belts with static electricity to load. to hold a paper web to the circulating belts.

Acetylcelluloseüberzüge, die durch Reibung in höherem Maße elektrisch werden als Hartgummiplatten, haben gegenüber den bekannten Anordnungen den Vorteil, daß sie in Form einer Lösung oder in Form von biegsamen Folien leicht auftragbar sind. Es genügt schon eine 0,03 mm starke Schicht, um Blätter auf den Arbeitsgeräten festzuhalten.Acetyl cellulose coatings, which become more electrical than hard rubber plates through friction, have the advantage over the known arrangements that they can be easily applied in the form of a solution or in the form of flexible foils. A 0.03 mm thick layer is enough to hold leaves on the work tools.
