Abstract: A spacer applicator assembly has tooling with a plurality of retention devices. An actuator is coupled to the tooling, where the actuator is adapted to continuously rotate the tooling about an axis in a first direction and the tooling is adapted to move in a direction that is generally parallel to the axis.

Abstract: A spacer assembly has a first end and a second end. A first elongate strip extends from the first end to the second end and a second elongate strip is spaced from the first elongate strip, and also extends from the first end to the second end. A sealant is disposed between the first end and the second end and a first flap protrudes from the second end and overlaps a portion of the first end. In a variety of embodiments a primary seal is defined between the first end and the second end and a flap protruding from the second end and extending over the first end defines a secondary seal.
