Machine for the production of polygonal plates from an endless web of material

The invention relates to a machine for producing polygonal plates from an endless web of material.

Polygonal panels made of PVC and the like, for example for floor coverings, are usually made from primary material in Shape, punched out of large-format plates. The discontinuous Production method is labor and time consuming. In addition, it falls with the usual punching process undesirably a considerable amount of waste.

The innovation lies in the need for a rational one and material-saving way of producing polygonal plates.

The need is renewed according to a machine for the production of polygonal plates from an endless Material web taken into account, which essentially consists of a machine frame with a stored therein, a Support made of hard rubber having roller as an abutment for another associated with the machine frame, opposite the the roller forming the abutment adjustable driven knife roller, one in the transport direction in front of the roller set arranged driving roller set, one in the transport direction resiliently mounted in front of the brake roller and one in the transport direction in front of it arranged deflection roller for the one stored in a roller device assigned to the machine Roll of material to be withdrawn exists.

From the material web introduced into the machine with the help of the knife roller continuously cut out polygonal plates, with the appropriate knife arrangement or appropriate Plate blanks without waste, with the corresponding roller having a hard rubber pad

which forms the abutment for the knife roller. The uniform feed required for uniform panel cuts the material web to the knife roller is through the in the transport direction of the material web in front of the roller set for dividing the material web arranged drive roll, of which a roller is driven together with the knife roller is effected. The braking roller provided in front of it in the transport direction then ensures a constant passage also of the outgoing end of the running off a roll of material in order to move the pulley into the plane of the Roll gap transferred material web safely.

The adjustable knife roller enables the machine to be adapted to different material thicknesses. Have it manufactured PVC sheets, in particular, but also sheets made from other sheets can be divided up in a corresponding manner on this machine Materials. One in the transport direction in front of the roller set provided for dividing the material web, the material web undercatching heating plate facilitated by Heating the web to be cut the cutting process.

Knives that are detachably arranged on the knife roller with the aid of clamping jaws or the like enable replacement

the knife and / or the change in the knife arrangement.

In addition to the possibility of producing polygonal panels from endless material webs without waste, it is also known the new machine is characterized by its great performance.

In the drawing, the innovation is based on an exemplary embodiment explained. Show it;

FIG. 4 shows the partially illustrated development of the knife shaft.

The machine consists of the frame structure 111 with the uprights 111 *, 111 ", in which the adjustable (double arrow A in Figure 1) knife roller 12 and a roller 13 with a hard rubber pad that forms the abutment; 121, 131) .In front of the roller set 12, 13 in the direction of travel of the belt (arrow B in FIG. 1), a drive roller set 14, 14 * provided with a hard rubber pad is mounted (14l, 14i ^! ). In the transport direction in front of it, a brake roller 16 is resiliently mounted (16l ) and in front of it in the transport direction a deflection roller 17 for the material web 184, which is withdrawn from the material roll 18, which is underpinned by two rollers 191 which are arranged at a distance from one another and which form part of the Abro 1.1 device 19.

In the transport direction in front of the roller set 12, 1.5 is beyond a heating plate 12 which underpins the material web 18l is provided.

Knives 132 are fixed on the knife shaft 18 in accordance with the desired panel blanks (FIGS. 1 and 3).

Corresponding to the development of the knife shaft 12 in FIG the plate blanks produced from the material web 18l l8l *. The knife arrangement shown represents only one possibility, other knife arrangements and thus others Panel cuts or shapes are basically possible. In particular, the manufacture of rectangular Panel cuts possible with the help of the machine.

Knife shaft 12 and upper drive roller l4l * are common driven.

The braking roller l6 rests resiliently against the material web l8l.
