Shuttle propelling mechanism in circular loom

In a circular loom comprising an annular guide means for guiding at least one shuttle in a predetermined direction, a warp guide annular member disposed above said annular guide means coaxially therewith and having a plurality of warp guide slits, a plurality of shed forming mechanisms arranged annularly outside said warp guide annular member, a cylindrical cam mechanism mounted coaxially with said shuttle guide means, means for operating said shed forming mechanisms prior to arrival of the shuttle to form moving sheds, in a condition of successively forming sheds along said annular guide means, a mechanism for taking out a woven fabric along the axis of said shuttle guide means and driving means for rotating the cylindrical cam mechanism around the axis thereof in the direction of guiding the shuttle by the shuttle guide means, a shuttle propelling mechanism comprising a horizontal supporting member mounted rotatably at a position above said cylindrical cam mechanism on an upward extension of the rotation shaft of the cylindrical cam mechanism, at least one horizontal shaft corresponding to the shuttle to be used, said horizontal shaft being fixed to said supporting member and being extended to a position adjacent to said shuttle guide means, a shuttle engaging mechanism mounted on a free end portion of said horizontal shaft and means for transmitting the rotation of the cylindrical cam mechanism to any of said horizontal shafts.
