摘要:
A method of producing a contact filter block comprising the steps of supplying a granulate material to a heating and pressurising unit from a reservoir conveying the granulate material along a path of travel, heating the granulate material and pressurising the granulate material to an elevated pressure while conveying the granulate material along the path in a heating and pressurising unit, the heating and pressurising being performed according to a specific heating and pressurising profile, transferring the heated and pressurised granulate material to the extruder unit, heating the granulate material within the extruder to a temperature, extruding the mesh-type structural structure from the granulate material, the heating of the granulate material causing an expansion of a foaming additive causing the mesh- type structural structure to obtain a porous structure, cooling the extruded mesh- type structural structure by means of a cooling unit according to a specific cooling profile thereby stopping or halting expansion of the granulate material and/or the foaming additive and locking or fixating the porous structure of the mesh-type structural structure, and cutting the mesh-type structural elements using a measuring and cutting unit.
摘要:
A ventilating closure for an eave of a roof structure and a method for mounting a closure for an eave of a roof structure. The roof structure comprises an elongated support member positioned at and along the eave and plates or tiles positioned above the elongated support member and the elongated support member has an upper support surface facing the plates or tiles. The plates or tiles define an undulated lower side facing the upper support surface of the elongated support member. The ventilating closure comprises a mesh-type structure for allowing a flow of air to pass through it, and the mesh-type structure is a unitary structure which defines an elongated base portion for positioning along the elongated support member and for contacting its upper support surface. A first number of surface portions are positioned in sequence along the elongated base portion and protrude from said base portion for conforming to the undulated lower side.
