Embodiments for clamps and shaping clamp systems are disclosed herein and drawn to such applications as, including but not limited to, an apparatus and method for forming three-dimensional woven preforms that can be curved and have continuous fibers in the direction of curvature. Embodiments of the clamps may include an upper clamp, and a lower clamp of complementary shape and mateable with the upper clamp, with the clamp being configured to receive a fabric therebetween.

Object:

Conventional woven fabrics mounted on a loom have a fabric length difference between the center portion and the sides of the woven fabric, which increases the flaring rate. In the scouring shrinkage step, yarns shrink and the crimp ratio is changed, which further increases flaring.

Means for achieving object:

The use of a bar temple with a ring function in the weaving process reduces protrusions. Further, by setting the boiling-water shrinkage rate of incorporated additional yarn lower than that of base yarn, the shrinkage of the sides of the fabric can be efficiently suppressed.

A full-width temple device for a loom including: a base body including a base plate; a cover provided on the base plate; and a temple bar accommodated in a space defined by the base plate and the cover, where the temple bar is a ring bar temple constituted by a rod-shaped inner bar and ring temples provided continuously to both sides of the inner bar and having shaft parts for support at both ends. The base body has support parts at both end portions for supporting the ring bar temple on the shall parts. The full-width temple device includes attachment members each detachably attached to each of the support parts and comprising a plate-shaped shaft fixing part having an engaging part formed to engage with a circumferential surface of the shaft part.

The invention relates to various mutually combinable embodiments of a weaving machine or loom that comprises at least one guide device with at least one guide unit (32, 34) for the contacting guidance of a woven fabric (82) in the area of the weaving reed beat-up plane (14). In this regard, according to an embodiment, a control unit (15) is provided, which is embodied for controlling at least one drive (38, 39) for the at least one guide unit (32, 34), wherein for the actuation the control unit (15) processes informations that are related to the woven fabric structure in the area of the weaving reed beat-up plane (14), and/or informations regarding the position of the warp threads (80a, 80b) in the open loom shed. The invention also relates to methods for guiding a woven fabric in the area of the weaving reed beat-up plane (14).
