ABSTRACT:
Device for changing the reed beating position in looms for terry fabrics, in which the feet of the followers rigid with the reed are respectively connected by connecting rods to corresponding cams keyed on a shaft rotatably supported by the machine sley in proximity to the rotational axle of said sley.
A gear is keyed on to said shaft and engages with a toothed sector supported by a member idly mounted on said rotational axle of the sley and is hinged to the lower end thereof by two arms hinged together, their common joint being inserted and guided in an aperture in the form of a circular arc formed in a vertical rocker arm hinged to a fixed part of the loom at the lower end of its aperture, and kept resting on a fixed shoulder of the loom by a spring, in which position said aperture constitutes an arc of a circle having its center on said rotational axle of the sley.
Finally, the ends of two bars are hinged at two different points to the shank of said vertical rocker arm, the other ends of the bars being inserted into corresponding vertical parallel slots in a control lever operated by a control cam, where they rest on supports supported by said control lever at the lower ends of said vertical slots, said bars being individually connectable to said control lever by connecting pins which can be inserted into an axial slot in said other ends of the bars by the action of two electromagnetic controls supported on the opposing faces of said control lever.
