Abstract: Waste selvage containing warp ends or leno yarns interlaced with filling tails is removed from a shuttleless loom. The loom includes a suction source having an impeller pump with an exhaust, with fabric being removed by a fabric take-up roller. A venturi is disposed below the fabric take-up roller in operative association with waste selvage from fabric being taken up by the roller, the exhaust from the impeller pump being connected to the venturi to provide the motive power for the venturi to suck waste selvage through the venturi and deposit it in a waste selvage container. Draw-off wheels are provided between the venturi and the fabric take-up roller, the venturi preventing the selvage from clinging to the draw-off wheels, and being wound onto the wheels, without any energy penalty. A baffle at the venturi induces rotary turbulence to cause the filling tails and warp ends or leno yarns to twist together so the filling tails will not be blown away by air passing through the venturi.
