ABSTRACT:
A loom with two or more sectional warp beam, each associated with a measuring device for detecting the length of at least one of the warp threads, which runs off the sectional beam in question during a given advance of warp thread. Each measuring device has a measuring roller which is urged against a number of warp threads, e.g., against the circumference of the wound sectional warp beam and which is driven by them during the advance of warp thread, so that it is able to transmit a corresponding control signal to a control equipment. The control equipment regulates the r.p.m. of the sectional warp beams in dependence upon these control signals in the sense of keeping constant the predetermined length of any given warp thread advance. The invention is particularly useful for weaving off sectional warp beams having different winding diameters for assuring a homogeneous appearance of the weave across its entire width.
