Benefits of technology
[0012]In a preferred embodiment, the device comprises means for adjusting a cross-sectional area of compressed thermal insulation material. Thereby, the rate of compression of the thermal insulation material can be adjusted. Preferably, the means for adjusting a cross-sectional area of compressed thermal insulation material comprises an adjustable wall, preferably a vertically adjustable upper wall, which, when the adjustable wall is adjusted, adjusts the area of an opening defined by the adjustable wall, two side walls and the support surface. This provides for a mechanically simple design.
Problems solved by technology
Due to the power needed to break apart pieces from the compressed material, the engine driving the rotating arms has been forced to be very powerful.
With relatively long arms it is also difficult to receive an even density of the fluffed insulation material.
A material with an uneven density containing lumps of material is difficult to distribute into the structure.
However, due to the great amount of energy needed to break apart a compressed material it is difficult to use an even more compressed loose-fill material in an insulation apparatus according to the above description.

Embodiment Construction
[0021]The invention will now be described in more detail in respect of embodiments and in reference to the accompanying drawings. All examples herein should be seen as part of the general description and therefore possible to combine in any way in general terms. Again, individual features of the various embodiments may be combined or exchanged unless such combination or exchange is clearly contradictory to the overall function of the device.
[0022]FIG. 1a shows a device 100 for compressing thermal insulation material into blocks of insulation. The device comprises a support surface 110 for compressed blocks of insulation, of which one designated 200 is shown in the figure. The compressed block of insulation 200 is comprised of several portions 200b, as will be described below. The support surface 110 is in the embodiment shown in FIG. 1 essentially horizontal, but it could also be slanting. Two side walls 150, one of which is shown with dashed lines, are provided on the support surfa...

The invention relates to a device (100) for compressing thermal insulation material into blocks of insulation comprising: a support surface (110) for the compressed blocks (200) of insulation, a compression device (120) with a compression surface (120a), and a feeding device (130) for feeding thermal insulation material. By adapting the compression device (120) for reciprocal movement between a first position, wherein the feeding device (130) is allowed to feed thermal insulation material to a position on the support surface (110), and a second position, wherein, during movement from the first position to the second position of the compression device, thermal insulation material (200) fed by the feeding device (130) is compressed, highly compressed blocks of thermal insulation material is obtained that are suitable for use with known shredding devices. A corresponding method is also provided.
Description
TECHNICAL FIELD[0001]The present invention relates to a device for compressing thermal insulation material, preferably loose-fill cellulose thermal insulation, into blocks of insulation, and a method for compressing loose-fill cellulose thermal insulation material.BACKGROUND ART[0002]Loose-fill insulation is used to insulate structures and buildings and is a quick and convenient alternative to insulation with mineral wool isolation batts. The loose-fill insulation is with the assistance of compressed air blown by an insulation apparatus into cavities in the building structure, such as for example into walls and on attics, forming a heat and cold insulation layer. In order for the cellulosic fibers to be able to withstand the various conditions in building structures it is treated with various additives having fire retardant and other properties. Cellulosic fibers are organic and are therefore an environmental friendly and renewable insulation material. Loose-fill cellulose thermal i...
