Device for compressing blocks of insulation and method for compressing blocks of insulation

A method for compressing loose-fill cellulose thermal insulation material into a compressed block of cellulose thermal insulation having a predetermined size, wherein the method comprises the steps of:

• a) providing a support surface having a first surface region for receiving and supporting loose-fill cellulose thermal insulation material thereon and a second surface region for supporting thereon a compressed block of cellulose thermal insulation;
• b) feeding an amount of the loose-fill cellulose thermal insulation material onto the first surface region of the support surface with a feeding device,
• c) compressing the amount of loose-fill cellulose thermal insulation material fed in step a) by moving a compression device in a direction parallel to the support surface between a first position, wherein the compression device is positioned near the first surface region of the support surface to allow the loose-fill cellulose thermal insulation material to be fed onto the first surface region of the support surface, and a second position near the second surface region of the support surface to thereby form an initial block of thermal insulation,
• d) feeding an additional amount of the loose-fill cellulose thermal insulation material to the first surface region of the support surface while the compression device is in the first position thereof,
• e) compressing the additional amount of loose-fill cellulose thermal insulation material fed onto the first surface region of the support surface according to step d) to add additional compressed cellulose thermal insulation material to the initial block of cellulose thermal insulation and form a block of cellulose thermal insulation having increased size, and
• f) repeating steps d) and e) to until the compressed block of cellulose thermal insulation has a predetermined size and a density of at least 160 kg/m3, and wherein
• the method further comprises a step of adjusting a cross-sectional area of the compressed block of thermal insulation material by an adjusting means comprised of two side walls, the support surface, an adjustable wall and at least one screw which are configured to allow vertical adjustment of the adjustable wall at an entrance of an opening defined by the adjustable wall, the two side walls and the support surface.
