A loom is equipped with a pneumatic slide bearing for guiding and supporting a weft insertion gripper carrier, which may be a rigid rapier rod or a flexible band. The pneumatic slide bearing supports and guides the weft gripper carrier in a nearly friction-free manner. The pneumatic slide bearing includes a bearing body (1) that is pivotally mounted on a bolt (3) and that extends along the lengthwise direction of the rapier rod (12) or around the circumferential direction of the flexible band (21). The bearing body (1) has an air channel (5) therein, and has a plurality of transverse holes (6) passing from the air channel out through a side wall. A bearing plate (8) with a plurality of transverse holes (9) therethrough is removably mounted along the side wall of the bearing body (1) so that the transverse holes (9) align with the transverse holes (6). The outlet ends of the transverse holes (9) are enlarged to form respective air pockets (10), which together serve to form a homogenous and stable air cushion between the rapier rod and the bearing plate (8). Removable air nozzles (11) may be screwed into the transverse holes.
In a rapier loom having a loom shed, a weft insertion gripper carried on a rigid rapier rod, and a drive wheel that engages said rapier rod and that is adapted to rotate alternately in opposite directions so as to drive said rapier rod carrying said gripper back and forth into and out of said loom shed,
In a loom having a loom shed, a weft insertion gripper carried on a flexible band, and a drive wheel that engages said flexible band and that is adapted to rotate alternately in opposite directions so as to unroll said flexible band from said drive wheel and roll said flexible band onto said drive wheel and thereby to drive said flexible band carrying said gripper back and forth into and out of said loom shed,
A pneumatic slide bearing for guiding and supporting a carrier member for carrying a weft insertion gripper in a loom, comprising a bearing body that has an air channel extending longitudinally therein alone a longitudinal extension direction of said pneumatic slide bearing and that includes a side wall bounding said air channel on a side adapted to be arranged facing toward the carrier member of the loom, and a bearing plate that is removably connected to said bearing body and that extends along said side wall of said bearing body, wherein said side wall has a plurality of first transverse holes therein communicating with said air channel and passing outwardly through said side wall, wherein said bearing plate has a plurality of second transverse holes therein respectively communicating with said first transverse holes and passing outwardly through said bearing plate, and wherein said bearing plate further has a plurality of air pockets therein respectively located at and communicating with respective outer ends of said second transverse holes at an outer surface of said bearing plate facing away from said bearing body and adapted to face the carrier member of the loom.
