Abstract

The invention relates to manufacturing sandwich panels with a core of binder cured lamellas of mineral wool whose main grain is perpendicular to the main plane of the panel, the individual lamella layers being displaced lengthways in relation to one another so that joints between successive lamella pieces in adjacent lamella layers fall in different lines across the lamella core. <IMAGE>

The invention further relates to a device for carrying out this system.

Prior art

In the production of sandwich panels with a core of mineral wool in core panels with a core and a top surface, the panel is assembled by glueing the base surfaces of the core or the cover layer, which are then deposited on the core. This work is usually done manually and is therefore very time consuming.

However, the mechanical method of making sandwich mineral wool is also known, for example from the German DE - A 3 3 2 and 3 4 2. According to this method, panels of cut sandwiches consisting of sandwiches are cut. a composition composed of transverse lamellae of glass wool, covered with covering layers of shoulder. A polyurethane fluid is injected between the three layers, i.e. between the layer and between the core and the lower surface layer, which are continuously moved. These three layers are joined together between two endless conveyor belts and glued together by 1 inch of glue to form a sandwich.

The invention relates to a process for the continuous production of sandwich panels with a lamellar core of longitudinal mineral wool lamellas by means of a binder, wherein the lamellar core is provided with cover layers of a material suitable for construction purposes, for example sheet metal, the cover layers being connected to the lamella core by bonding layers, in which the lamellae are cut from a mineral wool board, rotated about their longitudinal axis by 90 ° and assembled side by side in the longitudinal direction. Its essence is that the slats are assembled next to each other and their ends are longitudinally adjusted, pressed against the ends of the slats? A lamella strip is thus formed and a lamella mat is cut from which a lamella mat of the required dimensions is cut. A first cover layer is attached to the lamella mat on one side and a second cover layer is attached to the lamella mat on the other side.

for example, a quarter to six pieces. from the plate of the other lamellae which have been and have been rotated about their mineral wave by a longitudinal axis of 90 ° and this group is surrounded longitudinally by means of a group of lamellae which the adjusting member already brings into contact in this way. that the end lamella, for example from one adjusting member to the previous one has been adjusted, with the lamellae successively the side of the group, comes into contact with the melting member and starts to be adjusted first and the end lamella of the group side comes into contact with this member and adjusts last . In this way, the lamellae rearrange adjacent adjacent lamellae individually and between the opposite lamellae of the lamella core, so that these passing across the lamella adjusting member, abutting the mutually distributed / along the length of the joint do not form a straight line, the core. The contact surface of the end of the lamella parts is

-3Preferred stepped, ais can have a more irregular shape. The terms used, such as a lamella, a lamella core, a lamella assembly, etc., are explained in an exemplary embodiment of the invention.

When:

the lamellae o v v v, which is formed from groups of pressure-connected ones, reaches a sufficient length, is cut transversely and is moved to form a lamella core. Then, the formation of a novel lamella strip from the adjusted lamellas can be started by means of the adjusting means. The width of the lamella axis can naturally correspond to the width of the lamella core, and this is then formed without lateral displacement of the cut lamella mat.

Each individual lamella in a group of lamellas can be adjusted separately, i.e. they do not necessarily have to be adjusted at one time. It is also possible for each lamella in the core to be formed separately and fed to the finished lamella core.

until the lamellar core reaches its final dimensions, it will bring to the first covering

For example, the lamellar core could be lowered onto a stationary cover layer from its support and sliding plate, which is slowly withdrawn from the space below the core.

Men are a doorman and with the same this you find. is used on floors,

-4 ceilings and internal net-o external walls. Thanks to its large dimensions, it simplifies the work and is also very advantageous from an architectural point of view.

The different dimensions in the sandwich panel can be easily changed by feeding the relevant information into the memory of the processor unit of the production plant. Thicker panels can be obtained by increasing the width of the cut lamellas. For a thicker panel, a longer board length of hardened mineral wool is desirable. because more slats can be obtained from the same width of the board. The length of the panel can be varied by adapting the device to the desired longer lamella mat, i.e. more lamellae of the same length in each lamella mat, or the same number but longer lamellae in each lamella mat. The number of joints between the lamellas and the distribution of the joints along the lamella core affect the panel. Changing the width of the panel length requires a similar change in the dimensions of the cover layers.

To achieve first-class products, dimensional differences must be kept within very narrow tolerances. The continuous side and end surfaces of the slats should be smooth and in particular the end surfaces must have exactly the same shapes so that the ability of the slats in the slatted mat and the slatted mats in the slatted core to coalesce is not impaired and does not affect the strength values.

This method makes it possible to produce sandwich panels, the cores of which consist of longitudinal lamellae and mineral wool knives arranged side by side. These lamella mats can consist of a separate lamella or one or more lamellae connected at their ends to each other. The end faces may be grooved or otherwise mechanically modified to ensure coherence between them. Gluing may also be used. The joints should preferably be chamfered or otherwise bevelled together.

The device for carrying out the method according to the invention comprises cutting means for cutting the lamellae from a mineral plate, from which rotary means for rotating the lamellae by 90 ° are arranged.

A suitable material for the cover layer is a thin metal sheet, which is preferably bent at its edges and is cut to the required length according to the lamella core formed. The metal sheet can even be profiled on its entire surface.

The preferred material for joining the lamellar core to the cover layer is a polyurethane adhesive.

In the position in Fig. 2a are sections 3a. 3b of the support and transfer plate 8 on each side of the first cover layer 11a and the left section 3a of the support and transfer plate 3, which has a lamella core κ towards the conveyor 6 of the outlet. .is adapted to accommodate the lamellar core K. The first blood layer 11a lies on the conveyor belt 9a and is provided with a layer of glue by means of the first gluing device 12a. The left and right side stops 10a, 11b are still in their working position after the previous sandwich panel has been manufactured.

Meanwhile, the first cover layer ij_a was in position as close as possible to the sections 8. FIG. 2a to 2c show, to a position above the first cover distance raised in the transfer plate, that the transfer of the lamella core K to the layer 1.1a consists of the following steps:

- displacement by means of a displacement member equivalent to the width of the lamella core k

- lateral transport of the left iodine section 8a of the support and sliding plate 8 by a distance equivalent to half the width of the lamella core h and transfer to the section 8b of the support and sliding plate 3 by means of the sliding member 7 by a distance equivalent to half the width of the lamella core k ..
