Abstract

A loom that includes a pair of separate and independently rotating warp beams, mounted side by side; roller means common to said warp beams and with which the warp threads passing from the folders take cooperative contact; a single development regulating mechanism for the two warp beams of said loom and operatively connected with the roller means, and endowed with a variable speed output endless screw; in said development regulating mechanism, a rotating development or advance tubular shaft, which extends adjacent to one of said warp beams; a section or section of rotary shaft of development or advance, which extends inserted through the tubular advance shaft and includes an extension that extends next to the other warp folder, section adapted to rotate in unison with and with respect to the tubular shaft of Advance; gear gears in each of said warp beams and integral with them; a pinion in the advancing tubular shaft and in said advance shaft section rotating therewith, engaging one of said pinions with each warp bevel gear to move the latter; a helical cogwheel mounted rotationally on the advancing tubular shaft and meshing with said variable speed output auger; a gear housing case integral with said cogwheel and rotating therewith; inside said box, two conical toothed wheels keyed one to the advancing tubular shaft and another to the aforementioned advancing shaft section, and a pair of conical sprockets engaging said conical toothed wheels, rotatably mounted in said casing and forming with said casing. and with said conical toothed wheels the differential gear device that can operate automatically allowing a relative rotation of the tubular advance shaft with respect to the advance shaft section, corresponding to the variation in the speeds of rotation of said warp beams.
