A loom includes a rotary shaft bridged to a pair of side frames with being supported via bearings each provided in corresponding one of the side frames, the rotary shaft includes: solid shaft-shaped shaft parts supported by corresponding one of the side frames: and a hollow pipe-shaped main body part located between the shaft parts. The loom includes a bearing structure provided in at least one of existence ranges of the shaft parts between the side frames with respect to an axis line direction of the rotary shaft. The bearing structure includes: a rolling bearing into which one of the shaft parts is fitted; and a support body configured to support the rolling bearing.

A loom includes a pair of support shafts each provided to each of a pair of side frames and configured to rock, a rocking shaft connected to both the support shafts and bridged between the support shafts, a bearing structure comprising a bearing configured to rotatably support the rocking shaft, and a support body having an attaching surface, which is a surface to which the bearing structure is attached, and provided to extend in a weaving width direction. The support body has a position adjusting surface parallel to the attaching surface on at least one of both ends in a length direction.

In a method for three-dimensional weaving of a fibrous structure between layers of warp yarns and layers of weft yarns, the weft yarns are woven in a plurality of columns spaced apart from one another in a longitudinal direction. The method includes weaving deployment portions in the fibrous structure that is interwoven with an adjacent portion, the weft yarns of the weft yarn columns of the adjacent portion being juxtaposed in a first stacking direction perpendicular to the longitudinal direction. During the process of weaving the deployment portions, the weft yarns of each weft yarn column are positioned against the fell of the fibrous structure in stacking directions that are different from the first stacking direction.

A Jacquard type loom intended to produce a fibrous structure by three-dimensional weaving between a plurality of warp yarns and a plurality of weft yarns extending in a horizontal direction, the loom including a reed movable between a rest position upstream of the rapier and a beat-up position of a fell of the fibrous structure in a beat-up direction parallel to the horizontal direction. The reed includes at least two stationary portions forming an angle therebetween. The reed is mounted on the loom by means of a positioning mechanism able to orient the reed about an axis of rotation so as to adjust an angular position of the stationary portions of the reed relative to a horizontal reference plane. The loom comprises vertical translation means able to move the reed or the fell of the fibrous structure in the vertical direction.
