Abstract
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.
