Method of sealing a gap

摘要

A sealing unit for sealing a gap between a pair of surfaces, the apparatus comprising a nozzle for injecting sealant into the gap; two or more rollers; an endless track which passes round the rollers; and a curing device for directing energy into the gap to initiate cure of the sealant. The sealing unit is moved along the length of the gap. A sealant is injected into the gap from the nozzle and the track is rotated around the rollers as they are moved along the length of the gap. The track is pressed onto the first and second surfaces so the sealant in the gap is constrained by the track to lie substantially flush with the first and second surfaces. Energy is directed into the sealant with the curing device, the curing energy initiating cure of the sealant. The sealing unit is moved along the length of the gap at a rate such that the sealant becomes sufficiently cured when it is in contact with the track so that the track can be peeled away from the sealant as the track rotates round the second roller.
