The assembly table can have a table surface configured to receive first and second transparent window components, the table surface being positioned at an incline relative to a vertical position. The conveyor assembly can be configured to translate the first and second transparent window components along a translation pathway from a first end of the table surface to a second end of the table surface, the translation pathway being substantially parallel to the table surface. The projection component can be adjacent to the assembly table and can be configured to engage the first transparent window component to translate at least a bottom portion of the first transparent window component between an initial position and a first assembly position offset from the translation pathway. ## Claims ### Claim 1 A method of assembling an insulated glass unit (IGU), the method comprising: receiving first and second transparent window components at a table surface of an assembly station, the table surface being positioned at an incline relative to a vertical position; translating the first and second transparent window components along a conveyor assembly that defines a translation pathway from a first end of the table surface to a second end of the table surface,

substantially perpendicular to the table surface to movably offset the conveyor assembly; translating at least a bottom portion of the first transparent window component with the projection component between an initial position and a first assembly position offset from the translation pathway; and bringing the first transparent window component from the first assembly position into contact with the second transparent window component to form the IGU. ### Claim 2 (depends on 1) The method of claim 1, wherein engaging the first transparent window component and translating at least the bottom portion of the first transparent window component with the projection component further includes: receiving a bottom edge of the first transparent window component at a receiving surface defined between first and second edges of the projection component; and merging an extension surface of the projection component with the translation pathway upon extension of the projection component to the first assembly position. ### Claim 3 (depends on 2) The method of claim 2, further comprising engaging a press bar with a top portion of the first transparent window component, the press bar being configured to both push a front surface of the first transparent window component and support a back surface of the first transparent window component when the first transparent window component is offset from the table surface. ### Claim 4 (depends on 3) The method of claim 3, further comprising translating the second transparent window component along the conveyor assembly to a second assembly position such that the second transparent window component is substantially parallel to the table surface and behind the first transparent window component after the first transparent window component is extended to the first assembly position, wherein the second transparent window component has a spacer frame attached thereto. ### Claim 5 (depends on 4) The method of claim 4, further comprising, in response to the conveyor assembly translating the second transparent window component to the second assembly position, pushing the press bar against the front surface of the first transparent window component to connect at least a top portion of the first transparent window component to at least a top portion of the spacer frame to form a partially-mated IGU. ### Claim 6 (depends on 5) The method of claim 5, wherein the partially-mated IGU includes a gap between the bottom portion of the first transparent window component and a bottom portion of the spacer frame for receiving gas to form a gas-filled IGU. ### Claim 7 (depends on 4) The method of claim 4, further comprising receiving a finger of the press bar in a groove through the table surface at the initial position of the first transparent window component, the finger being configured to engage a top edge of the first transparent window component and to support the back surface of the first transparent window component when the first transparent window component is offset from the table surface at the first assembly position. ### Claim 8 (depends on 7) The method of claim 7, further comprising, in response to the conveyor assembly translating the second transparent window component to the second assembly position, disengaging the finger from the top edge of the first transparent window component and pushing the press bar against the front surface of the first transparent window component to connect at least a top portion of the first transparent window component to at least top portion of the spacer frame to form a partially-mated IGU. ### Claim 9 (depends on 8) The method of claim 8, wherein the partially-mated IGU includes a gap between the bottom portion of the first transparent window component and a bottom portion of the spacer frame for receiving gas to form a gas-filled IGU. ### Claim 10 (depends on 3) The method of claim 3, further comprising translating the second transparent window component and a third transparent window component along the conveyor assembly to a second assembly position where the second and third transparent window components are substantially parallel to the table surface and behind the first transparent window component after the first transparent window component is extended to the first assembly position, wherein the second and third transparent window components have one or more spacer frames attached thereto. ### Claim 11 (depends on 10) The method of claim 10, further comprising, in response to the conveyor assembly translating the second and third transparent window components to the second assembly position, pushing the press bar against the front surface of the first transparent window component to connect at least a top portion of the first transparent window component to at least a top portion of one of the one or more spacer frames to obtain a partially-mated IGU. ### Claim 12 (depends on 11) The method of claim 11, wherein the partially-mated IGU includes a gap between the bottom portion of the first transparent window component and a bottom portion of the one of the one or more spacer frames for receiving gas to form a gas-filled IGU. ### Claim 13 (depends on 10) The method of claim 10, further comprising receiving a finger of the press bar in a groove through the table surface at the initial position of the first transparent window component, the finger being configured to engage a top edge of the first transparent window component and to support the back surface of the first transparent window component when the first transparent window component is offset from the table surface at the first assembly position. ### Claim 14 (depends on 13) The method of claim 13, further comprising, in response to the conveyor assembly translating the second and third transparent window components to the second assembly position, disengaging the finger from the top edge of the first transparent window component pushing the press bar against the front surface of the first transparent window component to connect a top portion of the first transparent window component to a top portion of one of the one or more spacer frames to obtain a partially-mated IGU. ### Claim 15 (depends on 14) The method of claim 14, wherein the partially-mated IGU includes a gap between the bottom portion of the first transparent window component and a bottom portion of the one of the one or more spacer frames for receiving gas to form a gas-filled IGU. ### Claim 16 A method of assembling an insulated glass unit (IGU), the method comprising: receiving first and second transparent window components at a table surface of an assembly station, the table surface being positioned at an incline relative to a vertical position; translating the first and second transparent window components along a conveyor assembly that defines a translation pathway that is substantially parallel to the table surface; engaging a bottom edge
