Patentiert im Deutschen Reiche vom 18. Juni 1904 ab.Patented in the German Empire on June 18, 1904.

Den Gegenstand der vorliegenden ErfindungThe subject matter of the present invention

bildet eine Maschine zur Herstellung solcher Deckmassestücke, aus denen gemustertes Linoleum zusammengesetzt wird, das eine Nachahmung von gemasertem Holzwerk, Marmor und . von anderen, eiri mehr oder weniger geädertes oder zusammengesetztes Aussehen besitzenden Materialien sein soll.forms a machine for the production of such pieces of opacity, from which patterned Linoleum is composed which is an imitation of grained woodwork, marble and. from others, eiri more or should be less veined or composite-looking materials.

Bei der Herstellung solchen Linoleums wirdWhen making such linoleum is used

ίο zunächst gewöhnliche Linoleummasse in gekörntem Zustande in den erforderlichen Farben, wie sie im Endprodukt vorhanden sein sollen, zusammengemischt und darauf einer Preß wirkung unterworfen, wodurch die Masse gestreckt und zu gleicher Zeit in die Form einer fortlaufenden Bahn überführt wird. Diese Bahn wird dann in Stücke oder Streifen von geringer Größe zerschnitten, die danach gründlich gemischt werden, wodurch sich die einzelnen kleinen Stücke so nebeneinander lagern, daß die verschiedenartigsten bunten Zusammenstellungen und Farbeneffekte erzielt werden. - Gleichzeitig wird diesen Stücken gewöhnlich noch eine weitere geeignete Menge gekörnter Linoleummasse beigemischt, die entsprechend der Grundfarbe gefärbt ist, die das fertige Linoleum besitzen soll. Das so gemischte Material wird dann wiederum zu einer Bahn geformt, aus der schließlich Deckmassestücke der gewünschten'Form und Größe geschnitten werden nach Maßgabe des besonderen Musters, das vermittels der Deckmassestücke erzielt werden soll.ίο Initially, ordinary linoleum mass in granular Condition in the required colors, as they are in the end product should be mixed together and subjected to a pressing effect, whereby the mass is stretched and at the same time transformed into the shape of a continuous path will. This web is then cut into pieces or strips of small size, which are then thoroughly mixed, making the individual small pieces so store next to each other that the most diverse colorful combinations and Color effects can be achieved. - At the same time there is usually another one of these pieces further suitable amount of granular linoleum mass added, which corresponds to the Basic color is colored, which the finished linoleum should have. The mixed material is then in turn formed into a web, from which finally pieces of covering mass the desired shape and size can be cut according to the special pattern, that is to be achieved by means of the covering weights.

Auf der Zeichnung ist eine zur Herstellung dieser Deckmassestücke dienende Maschine,The drawing shows a machine that is used to produce these pieces of covering weight,

teilweise schematisch, dargestellt, und zwar durch Fig. ι in einer Seitenansicht und durch Fig. 2 in Oberansicht. Fig. 3 ist eine Seitenansicht eines Teiles der Maschine.partly schematically, shown by Fig. ι in a side view and through Fig. 2 in top view. Figure 3 is a side view of part of the machine.

A A und ^¹ A¹ sind zwei Sätze Walzen, von denen der erste Satz A A mit größerer Umfangsgeschwindigkeit als der zweite Satz A¹A¹ angetrieben wird; außerdem ist der Abstand der Walzen voneinander bei dem ersten Satz geringer als der Abstand der Walzen des folgenden Satzes oder der etwa noch folgenden Sätze. Das Gemisch loser, körniger Linoleummasse wird dem ersten Satz Walzen zugeführt und durch dieselben zu einer dünnen, streifenartigen Bahn geformt, die zum nächsten Walzensatz A¹ geführt wird. Da die Walzen A¹-sich mit geringerer Umfangsgeschwindigkeit drehen als die Walzen A, so wird die von. letzteren kommende Bahn sich, wenn sie die Walzen A¹ erreicht, vor diesen etwas stauen. Da jedoch die Walzen A¹ weiteren' Abstand voneinander haben als die Walzen A, so wird sich die Bahn selbsttätig in etwas übereinander greifende Falten legen, um eine Bahn von größerer Dicke zu bilden, die durch die Walzen ^¹ weiter bearbeitet wird. Durch das vorerwähnte Übergreifen bei der Faltung der dünnen Materialbahn werden die Linoleummassen wieder gemischt und beim Durchgang zwischen den Walzen Α^λ A¹ überdies, wie bei jedem Walzwerk, gestreckt. Nach dem Austritt aus den Walzen A¹ gelangt die Bahn zu einer Schneidewalze B und wird von dieser in verhältnismäßig kleine Stücke zerteilt, die sodann in bekannter Weise mittels einer Stiftenwalze oder dergleichen in eine Misch-. AA and ^ ¹ A ¹ are two sets of rollers, of which the first set AA is driven at a higher peripheral speed than the second set A ¹ A ¹ ; In addition, the distance between the rollers in the first set is less than the distance between the rollers in the following set or any subsequent sets. The mixture of loose, granular linoleum mass is fed to the first set of rollers and formed by them into a thin, strip-like web which is fed to the next set of rollers A ¹ . Since the rollers A ¹ - rotate at a lower peripheral speed than the rollers A, the of. the latter coming web, when it reaches the rollers A ¹ , jam slightly in front of these. However, since the rollers A ^{1 are} further apart than the rollers A, the web will automatically fold itself into somewhat overlapping folds in order to form a web of greater thickness which is further processed ^{by the rollers 1.} As a result of the aforementioned overlapping when the thin web of material is folded, the linoleum masses are mixed again and, moreover, stretched when passing between the rollers Α ^λ A ¹ , as in any rolling mill. After exiting from the rollers A ¹ , the web arrives at a cutting roller B and is divided by this into relatively small pieces, which are then transferred in a known manner by means of a pin roller or the like to a mixing roller.

Claims

get trough C , in which there is a conveyor screw C ¹ or another suitable mixing and conveying device. Additional quantities of granular linoleum mass, which, as already stated, have a color corresponding to the filling base of the finished linoleum, can be fed into this channel. However, this supply of additional material can also be omitted.

ίο The materials are again thoroughly mixed together in channel C so that the various individually supplied pieces, due to their peculiar juxtaposition, result in the most varied combinations and effects. The mixed material leaving the chute is directed to rollers DD (see Fig. 3), by which the material is rolled into a sheet of the desired thickness. This web of material is then by suitable means, e.g. B. by the cutting rollers EE ¹ , cut into pieces of the desired size and shape, according to the requirements of the particular pattern. For which they are to be used, z. B. to imitate certain types of marble.
. If pieces of covering mass are to be produced which are to be used to imitate marble with a veined appearance, the strips obtained from the granular linoleum mass are divided into narrow, thread-like strips when they are first cut and then fed to the mixing and conveying channel C , into which at the same time As mentioned above, the base material is passed. However, the above-described rolling and cutting device is not suitable for producing these thread-like narrow strips. It is therefore for this purpose, namely in the embodiment shown in the drawing, in addition to the above-described rolling and cutting device AAA ¹ A ¹ B on the other side of the mixing and conveyor trough C .noch a second rolling and cutting device is provided. The same consists of the pairs of rollers FFF ¹ F ¹ , the following arrangement. own. At a suitable distance below the rollers FF, to which the granulated linoleum is fed instead of the aforementioned rollers AA , the rollers F ¹ F ¹ (see FIGS. 1 and 2) are arranged, which rotate at a slower speed than the rollers FF, see above that the material web has a tendency to pile up on the rollers F ¹ F ¹ . One of these latter reels is with a row. of V-shaped or otherwise suitably shaped

Provided annular grooves and causes the wide .Material web is divided into thread-like narrow strips. A scraping plate F ' ² or some other suitable arrangement is expediently provided between the grooved roller and the channel C , and that the same serves to remove the thread-like narrow strips from the roller and to guide them into the channel C. The material then also passes from the channel to the rollers DD, which form it into a web, and on to the cutting rollers EE ¹ or a similar arrangement in order to cut the web into pieces of the desired size and shape, as described above. During the passage of the material through the machine for the production of decking pieces to achieve granite or veining effects, the surface thereof becomes blurred and therefore requires further treatment in order to give it a clear appearance. For this purpose, a grinding device known per se is provided which acts on the web before it is cut into the pieces of covering material. This device, as usual, expediently consists of a roller G (see FIG. 3) lined with sandstone, emery or the like, which rotates in a container with water G ¹ and is in slight contact with the surface of the web while this runs around the roller G ^{2 arranged over the roller G.} Roller G is driven at a relatively high speed, in the opposite direction in which the web is moving. When the web leaves roller G, it goes around roller E ¹ and reaches cutting roller E, by which it is cut into pieces of the required size and shape.
