Abstract
A loop for providing a ladderless woven fabric made from warp and weft threads and with a stitch-like appearance. In the loom the warp threads (3) pass into holes of thread guides which are mounted side by side on a shaft (7), rotatably drivable through approximately 180.degree. about its axis between first and second positions; the warp threads (3) initially define triangles at the center of which are provided openings (14) for the insertion therethrough of weft threads. During the forward rotating movement, the threads (3) close around the weft thread, and the latter leaves the thread guides by way of slots (15), after which, as the thread guides execute a return stroke, the triangles reform around the openings (14).
Claims8
A loom for weaving fabric having warp and weft threads, comprising a common support shaft, thread guides fixedly mounted side by side on said common support shaft, each of which thread guides has a substantially semicircular outer edge, at least two holes through which an associated warp thread may pass successively, an opening for the insertion of weft threads through the assembly of thread guides and a slot which connects the opening of each said thread guide with the outer edge thereof, wherein the common support shaft has a longitudinal axis and is drivably mounted for rotation between a first and a second position through an angle of approximately 180.degree. about said axis, wherein the semicircular outer edge of the thread guides has a centre substantially coinciding with said axis, wherein said at least two holes are provided in each thread guide at locations close to said outer, semicircular edge of said guide, wherein said slot is curved in a direction opposite to the direction of rotation executed by the thread guide in moving from the first to the second position, and wherein there is provided a stationary table for supporting the woven fabric produced by the loom, which table is associated with a control plate and is positioned in a plane which includes said axis at a point located substantially diametrically opposite the last hole of said at least two holes through which warp thread passes when the thread guide is in its first position, each warp thread passing from said last hole towards said stationary table, wherein the insertion of the weft thread into said openings by said guides takes placed whilst said guides are in said first position, and said weft threads leave said slots when the thread guides are in their said second position.
