A loom is described which comprises a drum rotating on a rotary shaft, means for feeding the warp threads on the drum, means for inserting weft threads into sheds formed by the warp threads, peripheral weft bobbins and means for collecting the woven cloth. The drum consists of two first coaxial discs spaced one from the other at a predetermined distance, along the shaft, a plurality of second discs arranged in rows and mounted between the two first discs, each of the second discs having a first pulley portion and a second pulley portion, the first pulley portion being of greater diameter and the second pulley portion being of smaller diameter and one of the warp threads alternately goes over the pulley portion of smaller diameter and then the pulley portion of larger diameter while another warp thread alternately goes over the pulley portion of larger diameter and then the pulley portion of smaller diameter to form a crossed pattern. The second discs are carried by spindles arranged axially at equal distance from the shaft and form a cylindrical surface coaxial with the shaft. A pair of third discs mounted on the shaft carries means supporting the peripheral bobbins and means for guiding and tensioning the weft threads; the means for inserting weft threads into the crossed patterns formed by said warp threads are mounted on a second rotatable drum coaxial with the first drum. The second drum consists of two coaxial fourth discs and the means for inserting weft threads comprise a plurality of lances mounted peripherally on the second drum and a plurality of guides mounted between the fourth discs. The lances have a projection and the loom comprises means for imparting oscillatory motion to the lances in an axial direction. |
