Abstract: A ventilator includes a ventilation drive configured to drive ventilation gas from a gas source to a patient and a patient interface section configured to guide inspiratory gas from the ventilation drive to a patient connection, receive expiratory gas from the patient connection, and expel the expiratory gas out of the ventilator. The ventilation drive and patient interface section are configured to removably connect to at least one host comprising a ventilation path portion so as to divert the inspiratory gas through the ventilation path portion of the host when connected thereto.

Abstract: A vacuum belt conveyor of a web forming machine for transferring a threading tail has at least two turning rolls (16, 17) and an air-permeable belt loop (20), arranged around the turning rolls (16, 17). The vacuum belt conveyor also has vacuum means (22) for creating a vacuum effect on both the section of the belt loop (20) conveying the threading tail (23) and in connection with the first turning roll (16) of the turning rolls (16, 17). Arranged in connection with the first turning roll (16) in the travel direction of the threading tail (23) there is at least one cross-directional dividing structure (24) for creating at least two axial vacuum zones (25).

Abstract: A vacuum belt conveyor for transferring a web threading tail in a web manufacturing machine has a frame construction (15) and an air permeable belt loop (20), which is arranged around rolls (16, 17). The vacuum belt conveyor also has a first vacuum means (22) for creating a vacuum effect for the part of the belt loop (20) that transports the web threading tail (14) and a second vacuum means (23) for creating a vacuum effect in connection with the first roll (16). The second vacuum means (23) is arranged in the frame construction (15) for creating a vacuum to be introduced to the first roll (16) inside the belt loop (20).

Abstract: A belt conveyor for transferring a web threading tail in a web manufacturing machine has a frame construction (15) and a belt loop (20), which is arranged around rolls (16, 17). The belt conveyor has adjustment elements (21) for changing the relative position of the rolls (16, 17). The adjustment elements (21) include transfer elements (22), which are arranged in connection with both edges of the frame construction (15). The adjustment elements (21) act in mutual co-operation for moving the roll (17) by operating the transfer elements (22) from one side of the frame construction (15). A belt loop for the belt conveyor for a web threading tail in a web manufacturing machine is readily changed from one side of the conveyor.

Abstract: An apparatus for leading a web threading tail over an empty space formed between two surfaces, between which the apparatus (10) is arranged. The apparatus (10) includes a belt loop (28) permeable by air, which is supported by turnover rolls (29, 30). Within the belt loop (28) at least one foil strip (31) is arranged for creating a vacuum effect in the part of the belt loop (28) that transports the web threading tail (16) from the surface preceding the empty space, and to lead it to the following surface, a vacuum effect is arranged in connection with the first turnover roll (29) of the turnover rolls (29, 30).
