Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that upper and lower layers are supplied and molded, and a curable foam material is injected between these upper and lower layers so that the composite continuous body thus formed is laterally formed into a single piece. The present invention relates to a method for continuously producing a composite material having an end profile that complements the longitudinal bonding in the manner of being cut to length, and to an apparatus for carrying out the method as well as to such a composite material.

Such composite materials (e.g. magazines “Kunststof
fin Bau”, Volume 4, 1966, 42-5
(see page 0), the production of 11r? The manufacturing costs and machine costs per unit are relatively high.

In the known continuously working production equipment, composites are produced primarily of equal width, usually with a construction size of 1 m. In this case, since the manufacturing cost is high, 1t? ?
Efforts have been made to achieve the widest possible composite widths so as to cover as large an area as possible at the lowest possible manufacturing costs.

However, in the market, narrower composite materials are required, for example, when the area to be covered is relatively small, to avoid building panels on the exterior side of a building, or for architectural reasons. ing.

However, this leads to an increase in the costs required to modify the equipment for narrower composites - provided that modifications can be made to the manufacturing equipment, especially in terms of production per m'. This will increase costs.

The problem underlying the present invention is to create a method and a device that makes it possible to produce narrow as well as wide composites at approximately the same cost per m' and with the same output; It is to obtain composite material.

In order to solve the above problems, the present invention proposes the following in the method described in detail at the beginning.

That is, first forming a pre-treated composite comprising two terminal glofills and at least one terminal pre-glofill;
Thereafter, after solidification of the curable foam material, it is separated into two or multiple narrow composites, each with two complementary terminal globules, while being guided through the device.

The configuration according to the invention described above makes it possible to obtain a product that is significantly more cost-effective. This is because, in addition to a single narrow composite, multiple narrow composites can be obtained at approximately the same machine cost and at a production rate determined by the reaction time of the curable foam material. .

An advantageous feature of the invention is that the upper and lower layers are first formed against the pressure resistance of the curable foam material in the region of the end pre-profile and then separated when the necessary cutting force is obtained. At the same time, burr-free and molded,
For example, the shaping is carried out in such a way that a chamfered cutting edge is obtained and no chamfering is necessary afterwards.

Simultaneously with the separation of the upper and lower layers, the core of the curable foam material is also separated; however, the core of the curable foam material is only separated after the transverse cuts have been made to the individual lengths, for example, in a manufacturing plant. It is especially advantageous to carry out the process for the first time at a certain time or at a construction site, especially for 1/4-way subdivision and transport in general.

The end region can be additionally shaped after sectioning.

In this case, the shaping is carried out by processing the foamed end region as one piece. Thus, for example, a hooked-end profile can be formed.

A feature of the device according to the invention for implementing the method described above is that a dividing device is provided behind the double conveyor.

This dividing device consists of two profile roller cutters, and the mutual spacing between the profile roller cutters is approximately equal to the cross-sectional thickness of the dividing position minus two forming depths. It is advantageous to design the device in such a way that the curable foam core after subsequent severing is not yet sundered. The curable foam core is separated, for example, by a force-breaking device located behind the separating device.

In the composite according to the invention, the end face of at least one end profile is a longitudinally divided pretreatment stage-composite section.

The end profile may be formed from an entirely molded and foamed end region.

The invention will be explained in more detail below with reference to embodiments illustrated in the accompanying drawings.

As shown in FIG.
and the lower covering layer 4 pass through a shaping device 5, where these covering layers are shaped in accordance with the end profile 6 and the end profile 7. The molded upper and lower layers 3.4 are spray coated with a curable foam material in the foaming stage 8, which hardens during passage through the double conveyor belt 9. A joint that rotates about a vertical axis to limit the sides of the hardening foam.
One joint sealing belt 11 in each case runs from the ring belt stabbing roller 10 into each end profile 6, thus producing the pretreatment stage composite material 12 shown in FIG.
is formed.

In the cutting device 13, the upper and lower layers 3, 4 are first deformed against the resistance of the curable foam material by means of m=profile roller cutters 14, as indicated by dashed lines in FIG.
It is then separated when the cutting force is achieved. The curable foam material is cut by cutting the curable foam material because the distance between the Pro7 Ilroller cutters corresponds to the cross-sectional thickness at the cutting point VC, excluding the forming depth of the two layer sections for chamfering the end edges of the upper and lower layers. Not done. Pre-treatment Stage - The composite material is cut transversely into single lengths by means of transverse cutting chains 15 formed, for example, as saws, running in parallel as shown in FIG. be cut. This single length composite material is then cut into appropriate lengths, if appropriate at the construction site. Therefore, a relatively narrow composite material 16 each with two complementary end profiles 17 and 18 (in this case 17 corresponds to the previously formed end profile A) can be used together as a sea end profile 19.

The manufacture of the composite material 20 with an asymmetrical seam end profile 21 takes place according to the configuration shown in FIGS. 6 and 7.

The same applies to the composite material 22 shown in FIGS. 8 and 9 with a stepped groove-end profile 23.

Composite material 2 capable of bonding via hooked end profiles 25
The preparation of 4 is carried out analogously. This dowel end profile is formed entirely from a foam-molded end region 26.
