Abstract

The invention relates to a method for producing shutter boxes with a base body in profile form of stable plastic foam with U-shaped, downwardly open cross-section, first individual short profile sections are made in particular the same length, after which the individual short profile sections are attached to each other inextricably long body profile, the length of which is independent of the later required roller shutter box lengths, and wherein then the long composite body profile is cut into the lengths corresponding to the lengths of the required shutter boxes.

Description

The invention relates to a method for the manufacture of roller shutter boxes with a base body in profile form of stable plastic foam with a U-shaped, downwardly open cross-section.

It is known to produce shutter boxes made of foamed polystyrene. So it is from the German utility model DE 20 2007 002 372 U1 known to produce a roller shutter box of individual short profile sections (segments), which are fastened together. Here are so many segments juxtaposed that the desired roller shutter box length is exceeded. Thereafter, the one end forming segment is shortened so that all segments together form the desired length. Such a manufacturing process almost always requires shortening one of the segments and thus leads to undesirable waste.

The object of the invention is to improve a method of the type mentioned so that shutter boxes of different lengths can be produced without an attack of plastic waste.

• - dass zuerst einzelne kurze Profilabschnitte insbesondere gleicher Länge hergestellt werden,
• - dass danach die einzelnen kurzen Profilabschnitte aneinander unlösbar befestigt werden zu einem langen Grundkörperprofil, dessen Länge unabhängig ist von den später benötigten Rolladenkastenlängen, und
• - dass danach das lange zusammengesetzte Grundkörperprofil in die Längen geschnitten wird, die den Längen der benötigten Rolladenkästen entsprechen.

This object is achieved according to the invention

• that individual short profile sections, in particular of the same length, are produced first,
• - That then the individual short profile sections are attached to each other inextricably linked to a long body profile whose length is independent of the later required shutter box lengths, and
• - That then the long composite body profile is cut into the lengths corresponding to the lengths of the required shutter boxes.

Such a process ensures that plastic waste never forms in the manufacture of roller shutter boxes, regardless of which lengths are chosen. This does not create a large amount of work.

A particularly secure hold of the profile sections together is achieved in that the individual short profile sections are positively connected to each other. Here, the positive connection may be dovetailed. It is also proposed for this purpose that an adhesive is used for the connections between the individual short profile sections.

It is preferably proposed that the individual short profile sections consist of foamed polystyrene. The advantages of the method according to the invention are also achieved in that a Profilabschnittrest remaining after cutting to length, the length of which is not sufficient for a roller shutter box, is always extended again by adding individual short profile sections.

An embodiment of the invention is shown in perspective in the drawing and will be described in more detail below.

To produce roller shutter boxes of different lengths, several short profile sections 1 made of foamed polystyrene of the same length, which have a U-shaped, open at the bottom cross-section. In this case, the profile sections have a greater length L than height H or width B.

There are then two or more such same profile sections 1 permanently attached to each other in an indissoluble manner to form a long composite body profile. From this long body profile then the shutter boxes are desired length cut in the desired lengths are cut to length. A left after cutting remaining Profilabschnittrest whose length is not sufficient for a roller shutter box is always extended by adding individual short profile sections again.

A secure attachment of the end faces of the short profile sections together to form the long pre-body profile is achieved in that the end faces 2 dovetailed projections 3 and correspondingly shaped dovetailed recesses 4 exhibit. Alternatively or additionally, the end faces 2 additionally stabilized by an adhesive and or a positive connection in the form of a tongue and groove and connected together.
