1. A multi-curtain assembly having a plurality of adjacent curtain segments of retractable curtains, positioned in a structure, comprising:
a first curtain segment and a second curtain segment, each curtain segment having a leading edge configured to extend between opened and closed positions by winding on and unwinding from a respective barrel assembly, each barrel assembly being attached to a respective support bracket, and said support brackets forming an angle;
an edge fastener having a first portion and a second portion, at least one of the first and second portions arranged at a respective side edge of a respective curtain segment of the first and second curtain segments, a first portion of the first curtain segment being connectable to a second portion of the second curtain segment to align the side edges of the first and second curtain segments with respect to each other and to produce a seam as the first and second curtain segments are moved to their closed positions along a first direction;
an overlap fastener arranged proximate adjacent edges of the first and second curtain segments, the overlap fastener comprising, in an overlap region, aligning portions configured to align with each other as the side edges are brought into alignment by the edge fastener, and to releasably attach the aligning portions to one another, in the overlap region, to cause masking of at least one side of the seam of the edge fastener as the first portion and second portion of the edge fastener are connected to each other;
an edge fastener engager engageable with the first and second portions of the edge fastener and configured to connect the first and second portions of the edge fastener to each other when the first and second curtain segments move towards the closed position, and disconnect the first and second portions of the edge fastener when the first and second curtain segments move towards the open position;
at least one mounting bracket affixed to the support brackets;
an overlap fastener engager mounted on the at least one mounting bracket and positioned proximate the edge fastener engager, said overlap fastener engager being configured to engage the overlap fastener at a location on the curtain edges which is proximate a location where the edge fastener engager engages the first and second portions of the edge fastener to each other as the first and second curtain segments move toward the closed position;
a motor for driving one or more of the barrel assemblies; and
a synchronizing mechanism configured to ensure synchronization between the barrel assemblies;
wherein the edge fastener engager is positioned between the overlap fastener engager and the barrel assemblies.
