Abstract
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.
