A method and apparatus for the removal of one or more lateral yarns from a woven industrial textile to prepare it for seaming. The apparatus comprises a movable table, a clamping device to hold the fabric, and a yarn removal device, comprising a cutter and a combined hooked needle and thread catcher. In operation, the yarn removal device moves both vertically into and out of the fabric plane, and horizontally parallel to the longitudinal yarns, piercing the fabric at two locations, cutting one or more yarns, and then grasping the cut section(s) to pull them down and out of the fabric plane. The cycle is repeated to form a longitudinal channel of desired length; the device is then moved laterally and the cycle repeated until an open channel parallel with the lateral fabric edge is accomplished, resulting in reliable seam preparation with reduced damage to remaining yarns.
