  • Patent number: 5305803
    Abstract: A retoolable spreader table for an air loom has a trough-shaped cross-section. The spreader table has a projection pointing substantially toward the center of the weft thread insertion channel of a weaving reed. The projection forms with its upper side a support surface for the fabric. The spreader table is equipped with a first spreader element or forward spreader element positioned at the spreader table inlet and a second spreader element positioned at the outlet of the spreader table. A fabric detour element is positioned between the forward and rearward spreader elements in such a way that a slot is formed between the inlet spreader element (8) and a free end of the trough-shaped detour element (12). The fabric slot (16) has a free passage width that is variable, depending on the diameter (D) of a spreader rod (15) that is carried by the fabric (7) in a rotating manner and that is easily insertable into the space encircled by the trough table (1) and the detour element (12).

  • Patent number: 4834147
    Abstract: A scissors mechanism for cutting the weft thread in a shuttleless loom performs an excess stroke to bring the scissors mechanism, which is combined with a clamping mechanism, as close to the weft thread insertion gripper as possible in order to reduce weft thread waste. For this purpose, the fixed scissors blade is tiltable between a working position and a rest position in a plane extending substantially perpendicularly to the weft thread insertion direction. The movable scissors blade cooperates with a clamping arm for clamping the weft thread just prior to its cutting. For this purpose the movable scissors blade carries a clamping jaw next to its cutting edge and the clamping jaw cooperates with a clamping plate attached to a clamping arm coaxially mounted with the movable scissors blade.
