BEKANNTMACHUNG DER ANMELDUNG UND AUSGABE DERNOTICE THE REGISTRATION AND ISSUE OF THE

AUSLEGESCHRIBT: 7. DEZEMBER 1961 EXPANDED: DECEMBER 7, 1961

Die Erfindung betrifft ein Verfahren zur Herstellung von Kammrollen aus Kunststoff, wie sie als Aufreih- und Heftvorrichtung für lose Blätter verwendet werden.The invention relates to a method for the production of comb rollers made of plastic, as they are as Line-up and staple device can be used for loose sheets.

Nach einem bereits bekannten Verfahren wird ein flaches Kunststoffband mit auf beiden Längsseiten angeordneten Verstärkungsrippen derart ausgestanzt, daß sich zwei genau gleiche Kammteile mit abwechselnd nebeneinanderliegenden, gegenseitig gerichteten Zähnen ergeben. Die beim Ausstanzen entstehenden beiden Kämme werden anschließend einzeln in die gewünschte kreisrunde Form übergeführt.According to an already known method, a flat plastic tape is made with on both long sides arranged reinforcing ribs punched out in such a way that two exactly the same comb parts alternate with adjacent, mutually directed teeth result. The ones that arise when punching out Both combs are then individually converted into the desired circular shape.

Dieses Verfahren weist den Nachteil auf, daß die beiden in einem Arbeitsgang entstandenen Kämme zuerst auseinandergebrochen und dann einzeln der Rollierungsmaschine zugeführt werden müssen.This method has the disadvantage that the two combs produced in one operation must first be broken apart and then fed individually to the roller burnishing machine.

Bei dem erfindungsgemäßen Verfahren wird dieser Nachteil dadurch vermieden, daß die nicht ganz durchgestanzten beiden Kammteile gemeinsam rolliert werden und beim Rollieren in zwei Teile auseinan- ao derbrechen. Es entstehen dadurch in einem einzigen Arbeitsgang zwei fertiggebogene Kammrollen, die nicht mehr weiterbearbeitet werden müssen.In the method according to the invention, this disadvantage is avoided in that the not quite punched through two comb parts are rolled together and separated into two parts when rolling break. This results in two ready-bent comb rollers in a single operation no longer need to be processed.

In der Zeichnung sind die Verfahrensschritte schematisch dargestellt. Das von der Strangpresse oder einer ähnlichen Spritzmaschine bezüglich Breite, Stärke und der Form der Längsrippen äußerst präzise hergestellte flache Kunststoffband ist in Fig. 1 in Ansicht und im Querschnitt abgebildet. Fig. 2 zeigt das Band nach dem Stanzvorgang. In der Zeichnung sind die beiden identischen Bandteile, die je einen ebenen Kamm darstellen, zu erkennen. Der Kammsteg ist mit 1, die Zähne sind mit 2 bzw. 1' und 2' bezeichnet. Die zugehörige Randrippe ist mit 3 und 3' bezeichnet. Die nach dem Rollieren fertigen Kammrollen zeigt Fig. 3, und zwar beide Kammrollen vor dem Auseinanderspringen.The process steps are shown schematically in the drawing. The flat plastic strip, which is produced extremely precisely by the extrusion press or a similar injection molding machine with regard to width, thickness and the shape of the longitudinal ribs, is shown in view and in cross section in FIG. 1. Fig. 2 shows the tape after the punching process. In the drawing, the two identical belt parts, each representing a flat ridge, can be seen. The comb ridge is denoted by 1, the teeth are denoted by 2 or 1 'and 2'. The associated edge rib is denoted by 3 and 3 '. The comb rollers finished after roller burnishing are shown in FIG. 3, namely both comb rollers before they split apart.

Durch das erfindungsgemäße Verfahren ist eine vollständige Ausnutzung des Materials erreicht, da praktisch die gesamte Bandfläche zur Herstellung der beiden Kammrollen benutzt wird. Ferner ist das Herstellungsverfahren wesentlich vereinfacht worden, da alle Bearbeitungsvorgänge: Spritzen, Stanzen, Biegen, bei dem erfindungsgemäßen Verfahren nur einmal ausgeführt zu werden brauchen, um zwei fertige und vollkommen maßgerechte Kammrollen zu erhalten.The inventive method a complete utilization of the material is achieved because practically the entire belt surface is used to produce the two comb rollers. Furthermore, the manufacturing process has been significantly simplified because all processing operations: injection molding, punching, bending, only need to be carried out once in the method according to the invention, in order to produce two finished and to get perfectly tailor-made comb rolls.

Das erfindungsgemäße Verfahren gestattet also, mit sogenanntem zweifachem Nutzen zu arbeiten. Ein weiterer Vorteil ist ferner, daß sich das gespritzte Band zu einer Rolle aufrollen läßt und dadurch nach dieser ersten Verfahrensstufe leicht gespeichert werden kann. Die Herstellung kann also ohne weiteres in zeitlich getrennten Stufen erfolgen, so daß eine weitgehende Anpassung der Fertigung an den Bedarf ohne große Lagerhaltung möglich ist.The method according to the invention thus allows to work with what is known as a double benefit. A Another advantage is that the injection-molded tape can be rolled up into a roll and thus afterwards this first stage of the process can be easily saved. The production can therefore easily take place in temporally separated stages, so that an extensive adaptation of the production to the needs is possible without large storage.
