摘要： A duct of fibre material and binder agent, at least two fold lines are present lengthwise for providing a foldability of the duct by weakened material along the fold lines. The duct is pushable into a folded state and the material remembers the original shape and return to its original shape when released from a folded state. A method of manufacturing a duct: applying a web of origin fibre material with binder agent to a core and compressing the web by an outside form under the influence of heat against the core, wherein the core and/or the outside form is provided with a number of lengthwise ridges corresponding to the desired number of fold lines, to a third of the original thickness of the sides and at the ridges a tenth to a twentieth of the original thickness, and in that the fibre and binder agent web weighs 1,5-3 kg/m2.

摘要： Elongated ventilation duct comprising a fibre layer (2) without any splices and an inner layer (3) surrounding an elongated flow space (4), wherein



the fibre layer comprises mineral fibres and a binder, compressed into a desired duct shape, the fibres having a melting point over 800 degrees Celsius,
the inner layer is a stainless-steel foil having a thickness of 0.01-0.3 mm, facing the flow space.




A method of manufacturing a ventilation duct having a fibre layer (2) and an inner layer (3) of steel foil, wherein a binder solution is sprayed on the fibre layer, whereafter the fibre layer is compressed into a duct shape, having an elongated flow space (4), under heated conditions so that water in the binder solution evaporates, and bringing the inner layer into the flow space of the duct, which inner layer seals the flow space of the duct from the fibre layer.

摘要： Ventilation duct connector piece for connection with ventilation ducts or connector pieces, formed by two complementing parts (10a, 10) providing a flow space (4) and having at least two open ends (12), each part (10a, 10b) comprising a fibre layer (2) and an inner layer (3), wherein



the fibre layer (2) comprises mineral fibres and a binder, compressed into a desired shape, the fibres having a melting point over 800 degrees Celsius,
the inner layer (3) is a stainless-steel foil having a thickness of 0.01-0.3 mm, facing the flow space (4).




A method of manufacturing the connector piece wherein the steel foil is pressed into two complementing parts, joined along its edges; a binder solution is sprayed on a fibre layer and compressed into two complementing parts under heated conditions, so water evaporates, whereafter two fibre parts are positioned on the two steel foil parts.

摘要： A ventilation duct includes a refractory fibre material and binder agent and has longitudinal wall sections and longitudinal fold- or joint lines located there between. The wall sections between the fold- or joint lines have longitudinal, thickened and outwardly bulging portions in which longitudinal rigidifying dements are disposed. A method of manufacturing the ventilation duct includes manufacturing the duct in the planar, spread-out state, wherein the wail sections which are located along opposing edges of the spread-out duct, are given a configuration which corresponds the configuration of half of the other wall sections, whereby the duct, after raising to the intended configuration, is given a longitudinal joint where the half wall sections meet one another.
