For inserting a dividing cord loop into the opened shed warp on a sectional warping machine, a dividing device has at its disposal an introduction element (28) with a first, preferably movable guide arm (26) and a second, preferably stationary guide arm (27). The free ends (29, 31) of the two guide arms may preferably be led together in a pincer-like movement. The guide arms are preferably designed as tubes which in the led-together condition form a flow channel. With the help of an air conveyor (35), from a bobbin chamber (28) a dividing cord may be drawn off and as a loop be layed around a divided shed warp lying between the two guide arms and by way of a knotting means be connected to a cord loop. The connected cord loop is thereafter by way of a suction device or a blower device positioned and tensioned in a manner such that the cord loop bears at least on one side on the divided shed warp or on the warp web.
A method for thread division on a sectional warping machine (2), with which between the threads (5) of a shed warp (10) which are opened for shed formation there is inserted a dividing cord (22) for delimiting a divided shed warp (25a, 25b), wherein firstly an introduction element (28) consisting of a first and a second guide arm (26, 27) is laterally introduced into the shed warp, subsequently from a dividing cord supply a dividing cord is drawn off and by way of the introduction element, as a cord loop (23) embracing the divided shed warp, is applied into the shed warp in a manner such that the dividing cord is introduced along the first guide arm (26), turned and led back along the second guide arm (27), and wherein lastly the introduction element is retracted out of the shed warp and the cord loop is knotted, wherein the free ends (29, 31) of the two guide arms (26, 27) after the lateral introduction are brought together, wherein the dividing cord at the ends is directly transferred from the first guide arm to the second guide arm and the free ends for retracting the introduction element (28) are again opened.
A device for the thread division on a sectional warping machine (2), with an introduction element (28) consisting of a first and of a second guide arm (26, 27), which is introducable laterally into the threads (5) of a shed warp (10) opened for shed formation, wherein by way of an advance device (35) a dividing cord (22) is introducable along the first guide arm (36), turned and may be led back along the second guide arm (27), in a manner such that there is formed a cord loop (23) embracing a divided shed warp (25b), wherein the two guide arms (26, 27) are movably mounted in a manner such that their free ends (29, 31) may be led together.
