Weft threads are presented to a gripper in shuttleless looms by needles, each guided by at least one straight guide held askew in a needle guide carrier (9). These straight needle guides due to their askew arrangement make sure that all needles together are located in and displaceable in a fan type plane twisted in space. In the working position for presenting a weft thread each needle eye is located on a short line (7) extending approximately in parallel to a gripper path. Thus, all weft threads in their presenting position are close to each other in a narrow presenting zone within the reach of the gripper path for a sure gripping at the beginning of the forward gripper motion. At its beginning the gripper speed is still slow so that the weft threads are gripped gently. The straight needle guides held askew in the at least one guide carrier (9) form a row of guides which is slanted by a given angle relative to the gripper path to form the fan type plane twisted in space. A second row of askew straight guides may be arranged in a second guide carrier ( 10).
An apparatus for presenting weft threads to a gripper in a shuttleless loom, comprising a plurality of weft thread presenting needles each having an eye for holding a weft thread, needle guide means for movably holding and guiding each of said needles, needle guide carrier means for said needle guide means, mounting means for securing said needle guide carrier means to said loom, said needle guide carrier means having a longitudinal axis extending at a slant to a gripper path and toward heald shafts of said loom, said needle guide means having longitudinal axes with a skew in space relative to each other for locating and guiding said weft thread presenting needles in a fan type plane twisted or curved in space so that said needle eyes assume thread presenting positions all of which are located close to each other on a straight line (7) extending approximately in parallel to said gripper path.
