Abstract: A fast vertical sliding roller door includes a stationary portal structure mounted at the opening of a wall and comprising an upper cross-member and a pair of uprights made by hollow sections having a connecting plate for fixing to a side of the opening. A flexible closing element is slidably mounted along the uprights, whose longitudinal edges have projections slidingly mounted in a guide formation associated with a respective upright. One lateral face of each upright comprises at least one removable cover, the removal of which allows internal access to the upright, and is provided with a support profile having a pair of parallel flanges and an intermediate portion traversed by stems projecting from the guide formation. One flange has transverse slots for engagement of screws fixed along them by a nut, in order to adjust the transverse tension of the closing element.

Abstract: A high speed sliding roll-up door interposed between two rooms at different temperatures has a flexible curtain to close or open a passage of a wall separating these rooms. The roll-up door has two side uprights having guide rails of the side edges of the curtain, and an upper crosspiece near which there is a storage area of the curtain. A device for draining the condensation water present on the curtain includes guide rails having an upper rectilinear portion, close to the shelter area, and a lower rectilinear portion offset with respect to the upper rectilinear portion, between which an inclined portion is interposed which is connected upstream and downstream with the upper and lower rectilinear portion. Below the upper rectilinear portion there is a gutter formation configured to receive the condensation water present on the curtain, when this rises towards the shelter area.

Abstract: A portal structure has an air seal device including an air sealing element movable between a lowered and a raised configuration. The portal structure has a compartment for storing the closure element, delimited by a front wall. A space is provided which communicates with the compartment and with the outer environment between the wall and the closure element. The air seal device includes first and second sealing members adapted to reach a facing position in which they adhere by magnetic attraction to close the space, one connected to the wall for supporting a ferromagnetic plate, the other consisting of a magnetic member fixed to the closure element. The first sealing member includes a base structure which can be fixed to said wall by first and second adjustable fasteners in a position corresponding to the position of the sealing member fixed to the surface of the closure element.

Abstract: A device for controlling movement of a vertically sliding roller shutter door including a portal structure with uprights having guide rails for sliding a roller shutter for closing the door and a shelter zone for the roller shutter in the open condition delimited by an upper crosspiece, comprises motorized controllers for controlling movement of the roller shutter which are controlled by at least one operating member that generates an actuating signal for the motorized controller. The operating member includes an emitter indicative of an instantaneous setting of the roller shutter, and the device comprises a control unit connected to the operating member, to the emitter of signals of the operating members, to the motorized controller and to detector of the instantaneous attitude of the rolling shutter, to actuate the motorized controller and to emit a signal correlated with the instantaneous attitude of the roller shutter through the operating member.

Abstract: A liftable closure element movable between a lowered and a raised configuration, is associated with a portal structure having a compartment for storing the closure element, delimited by a front wall, a space being provided which communicates with the compartment and with the outer environment between the wall and the closure element. An air seal device for the liftable closure includes first and second sealing members adapted to reach a facing position in which they adhere by magnetic attraction to close the transverse space, one connected to the wall for supporting a ferromagnetic plate, the other consisting of a magnetic member fixed to the closure element. The first sealing member includes a base structure which can be fixed to said wall by first and second adjustable fasteners in a position exactly corresponding to the position of the sealing member fixed to the surface of the closure element.

Abstract: A vertically sliding roll-up door has a portal structure including vertical uprights provided with guide rails for guiding the sliding of blocks fixed along the lateral edges of the curtain, to allow the curtain to move vertically with respect to the portal structure. The curtain includes air-sealing gaskets which extend substantially over the entire length of the longitudinal edges of the curtain at the blocks, in order to block the passage of air between the guide rails and the blocks.

Abstract: A high-speed roll-up door for separating two rooms at different temperatures includes a flexible curtain to close or open a passage of a room separation wall, which passage is delimited, by a portal structure which includes a pair of hollow rails for guiding the curtain. The lateral edges of the curtain have projections for engaging cavities formed between the successive teeth of gear wheels for controlling the movement of the curtain. In the open condition of the door the curtain is received in an upper shelter area axially delimited by two guide panels having specular guide paths. Each guide panel comprises has a seat of a respective gear wheel arranged away from the wall to which the portal structure is associated with, and under the guide panels is prepared a tray for collecting the condensation water present on the curtain, to allow the curtain to be collected entirely above the tray.
