Retoolable trough-shaped spreader table for an air loom

A retoolable trough-shaped fabric spreader table for an air loom, comprising a table projection pointing substantially toward the center of a weft thread insertion channel, said table projection having an upper surface forming an extension of a fabric support of said spreader table, said spreader table further comprising a first spreader element (8) arranged at an inlet of said spreader table and a second spreader element (9) at an outlet of said spreader table, wherein said fabric spreader table forms a trough between said spreader elements (8, 9), a half shell shaped fabric detour element (12) insertable into said trough of said spreader table (1), means (11, 23, 24) for mounting said fabric detour element (12) inside said spreader table (1) in a form-locking and force-locking manner for a circumferential and axial displacement of said fabric detour element (12) relative to said spreader table (1), and wherein a fabric slot (16) is formed between said first spreader element (8) and a free edge (12A) of said fabric detour element (12), said slot having a clear passage width that is variable by said circumferential displacement of said fabric detour element (12) in accordance with a diameter (D) of a spreader rod (15) insertable into said trough, said spreader rod (15) being supported by a fabric (7) for simultaneously spreading and clamping said fabric.
