Abstract
A terry weaving method and a terry loom for carrying out the method. Subject matter of the terry weaving method is that a slay travel shortening does not result during the carrying out of partial beat-ups for the formation of a weft thread group, and thus the original weft thread insertion window remains maintained. The terry loom has a servo drive (7) that displaces the reed support shaft (4) in the direction of the shed forming means by at least the pre-beat-up distance (VD) while maintaining the basic stroke H of the reed (11) before the forming of the weft thread group, and that reverses or undoes the displacement by at least the pre-beat-up distance (VD) after the forming of the weft thread group.
Claims14
Terry weaving method for producing a terry fabric with variable loop height (12a) in the terry fabric (12), wherein a loom shed (15) consisting of ground warp threads (13) and pile warp threads (14) is formed in a first work step, wherein weft threads (16) are inserted into the loom shed (15) in a second work step, wherein each inserted weft thread (16) is partially beat-up and the weft threads (16) thereby form a weft thread group (16a) in a third work step, which weft thread group takes up a pre-beat-up distance (VD) relative to the beat-up edge (12b) of the terry fabric (12), and wherein the reed (11), while carrying out a basic stroke (H), beats up the weft thread group (16a) against the beat-up edge (12b) of the terry fabric (12) while forming pile loops (12a) with the pile warp threads (14) in a fourth work step, characterized in that, before the forming of the weft thread group (16a) the reed support shaft (4) is displaced by at least a rotational angle amount in the direction of the loom shed (15) forming means (17) in such a manner so that the basic stroke (H) of the reed (11) remains maintained in the forming of the weft thread group (16a), and in that, after the forming of the weft thread group (16a), the displacement of the reed support shaft (4) is reversed or undone by this rotational angle amount.
