Abstract
In a circular loom a reed and at least one shuttle are arranged between an upper and a lower running ring of a machine frame. A rotor driving the shuttle, a harness arranged in a concentric circle about the rotor for shedding the warp threads, and tensioning means for the warp threads also are provided. A wave-like extending groove is provided in the outer side of the rotor and catch elements engage therein. The catch elements are connected with flexible bands or cords carrying thread guiding organs arranged at a distance from one another. The bands or cords are deflected at least about upper deflection pulleys, the thread guiding organs coming to lie on opposite sides of the deflection pulley and the upper deflection pulley being at the height of the upper running ring. The distance between the upper and the lower running rings, as well as the maximum distance between the thread guiding organs at the deflected flexible band or cord, are dimensioned such that the shedding angle is sufficiently large to prevent a contact of the warp threads with the shuttle.
