PATENTAMT.PATENT OFFICE.

Die natürlichen Rauhkarden müssen, bevor sie verwendbar werden, an beiden Enden beschnitten werden, und zwar sind die Spitze und der Untertheil, die sogenannte Basis, an welcher die Krone mit dem Stengel sitzt, zu entfernen.The natural rough cards have to be trimmed at both ends before they can be used The tip and the base, the so-called base, on which the crown with the stem sits, are closed remove.

Die vorliegende Erfindung bezieht sich nun auf eine Maschine, mittelst welcher das Beschneiden der Karden schnell, genau und ohne Verletzung des Arbeiters von statten geht. Die Haupttheile dieser Maschine sind ein endloses Band, mit Kratzen oder dergl. ausgestattet, und Schneidorgane (Kreis- oder Bandsägen und dergl.), welche zu beiden Seiten des Bandes angeordnet sind.The present invention now relates to a machine by means of which trimming the card runs quickly, precisely and without injuring the worker. the The main parts of this machine are an endless belt, equipped with scrapers or the like, And cutting elements (circular or band saws and the like.) Which on both sides of the Band are arranged.

Die Maschine ist auf der beiliegenden Zeichnung näher dargestellt, und zwar zeigt Fig. 1 einen Längsschnitt und Fig. 2 ein Querschnitt. Fig. 3 und 4 geben den die Schutzleisten enthaltenden Theil der Maschine in zwei verschiedenen Phasen, Fig. 5 eine Aufsicht desselben Theiles.The machine is shown in more detail in the accompanying drawing, namely FIG. 1 a longitudinal section and FIG. 2 a cross section. Fig. 3 and 4 give the containing the protective strips Part of the machine in two different phases, Fig. 5 is a plan view of the same Partly.

Auf einem eisernen Untergestell wird das schon erwähnte endlose Band durch zwei Rollen b und b¹ gehalten. Von diesen Rollen ist die eine verschiebbar angeordnet, um die Spannung des Bandes reguliren zu können. Die Rolle b ist durch einen Riemenzug Z² mit der Antriebswelle der Maschine verbunden. Die Kreissägen f tragen auf ihren Wellen die Riemscheiben f'², welche mit Hülfe von Riemen/³ ebenfalls von der Antriebswelle der Maschine aus angetrieben werden. Die Bewegungsrichtung der Kreissägen ist aus dem eingezeichneten Pfeil in Fig. 1 zu ersehen.The previously mentioned endless belt is held on an iron base by two rollers b and b ¹ . One of these rollers is arranged to be displaceable in order to be able to regulate the tension of the belt. The roller b is connected to the drive shaft of the machine by a belt Z ^2. The circular saws f carry the pulleys f ' ² on their shafts, which are also driven by the drive shaft of the machine with the aid of belts / ^3. The direction of movement of the circular saws can be seen from the arrow drawn in FIG. 1.

Das Kratzenband bewegt sich mit seinem oberen Theile von rechts nach links gegen die Kreissägen. Das rechte Ende des Bandes a wird durch eine Schutzplatte d überdeckt, während an dem linken Ende eine geneigte, gleichfalls mit Kratzenband versehene Platte e angeordnet ist, auf welche die beschnittenen Karden von dem Band α abgelegt werden und auf welchem sie langsam herabsinken.The upper part of the scraper belt moves from right to left against the circular saws. The right end of the belt a is covered by a protective plate d , while at the left end an inclined plate e , also provided with a scraper belt, is arranged on which the trimmed cards from the belt α are placed and on which they slowly sink.

Als Schutzvorrichtung für das Bedienungspersonal sind ferner an den Seiten des Transportbandes α Schutzbleche angeordnet, welche ziemlich bis an die Spitzen des Kratzenbandes reichen. Aufserdem sind noch zwei als Schwinghebel ausgebildete Schutzleisten h vorgesehen, welche in einer gewissen Entfernung von den Kreissägen aufklappbar angeordnet sind. Dieselben sind auf einer Welle h¹ gelagert und mittelst einer Stange i mit einer Kurbel j¹ verbunden, welch letztere wiederum auf einer Welle j aufgekeilt ist, die mit Hülfe eines Handgriffes k gedreht werden kann. Auf der Welle j sitzt noch ein Arm /, welcher eine Spannrolle Z¹ trägt, mittelst welcher zum Ingangsetzen des Kratzenbandes der Riemenzug Z² gespannt wird. Α fenders are as a protective device for the operating personnel also on the sides of the conveyor belt arranged which fairly to rich to the tips of the card clothing strip. In addition, two protective strips h designed as rocking levers are also provided, which are arranged such that they can be opened at a certain distance from the circular saws. These are mounted on a shaft h ¹ and connected by means of a rod i to a crank j ¹ , which in turn is keyed onto a shaft j which can be rotated with the aid of a handle k. On the shaft j there is still an arm / which ^{carries a tensioning roller Z 1} , by means of which the belt pull Z ^{2 is} tensioned to start the scraper belt.

Ein zweiter auf der Welle j sitzender Arm n dient lediglich als Gegengewicht und ist bestrebt, die Welle j entgegen der Richtung des eingezeichneten Pfeiles zu drehen, dadurch das Kratzenband in Ruhe zu setzen und die Schutzleisten h in die Höhe zu klappen.A second arm n sitting on the shaft j serves only as a counterweight and strives to turn the shaft j against the direction of the arrow shown, thereby putting the scraper belt at rest and folding the protective strips h upwards.

Der Arm η wird mittelst eines Stiftes durch ein Gesperre m in seiner jeweiligen Lage gehalten. Das Gesperre m ist mit einem Hand-The arm η is held in its respective position by means of a pin by a locking mechanism m. The locking mechanism m can be

handle m ¹ provided and is held by a spring ¹ to the pin. In order to move the machine out, it is therefore only necessary to withdraw the lock by means of the handle m ¹ , whereby the arm η can act, the shaft _- ; rotates and so the scraper belt is stopped by releasing the tension of the belt pull P.

The circular saws f are for the most part covered by protective caps f ^l , so that here too there is no danger of injury to the operating personnel.

The conveyor belt α is, in order to prevent it from bending, supported by a beam c ² , the latter being held at its front ends by cross pieces c ¹ c ² . Below the interface for the cards are two bent sheet metal eggs ¹ , over which the cut ends of the cards slide out of the machine. Two larger containers ο o ¹ , arranged on both sides of the machine, are used to hold the cards to be cut; they are provided with a round bottom, so that the work piece always tries to collapse on one point, whereby the operation of the machine is made considerably easier.

Instead of a conveyor belt, as indicated in the drawing, you can of course several can be arranged both next to and above one another. For those arranged on top of each other Ribbons could use the same cutting organs. The arrangement of several ribbons next to each other would be are well suited for very large cards, to divide the useful part into several Cut pieces.

The machine is operated as follows:

The conveyor belt is loaded with the cards while it is at rest, whereby the protective strips h can be used as dimensions, which not only form protective strips but at the same time give a measure of the width of the cut to be made, since their distance from one another is the same as the the saw is. The machine is started as soon as the card sliver is loaded with cards.

At the moment when the conveyor belt starts to move, the bars h swing out and are positioned horizontally, in such a way that they do not constitute an obstacle to the card movement. It can be seen from the drawing (FIGS. 3, 4 and 5) that the shorter leg of the toggle lever serving as a protective strip is so short that when it is folded over, when it is in the position of FIG The surface of the card sliver protrudes and can thus also be an obstacle to the passing of the uncut cards.

Pa te ν τ-A ν speak:

A machine for trimming rough cards, characterized in that the Rough cards are fed on an endless scraper belt to two circular saws arranged on both sides of the latter, by which the cards are cut to the correct length on both sides at the same time will.

A machine for trimming rough cards of the type identified under 1, in which injury to the worker by the cutting tools when the cards are placed on the scraper belt is prevented by two protective rails (h) in front of the Set cutting tools that serve as a stop for the first card to be placed.
