Abstract: A twisting machine, which yields a twisted thread at an unusually constant twist value, comprises within a main frame first and second yarn paths converging toward a gathering point of respective yarns from a first reel carried on the main frame and a second reel carried on a spindle, a twisted thread path extending from the gathering point to a take-up reel driven rotatively by a roller, a flyer journalled in the main frame at the gathering point, and a capstan placed along the twisted thread path, and a positive mechanical drive for interconnecting rotatively the flyer, capstan, and roller directly with the spindle.

Abstract: The giver is used with a gripper loom having a stationary weft supply and includes a tongue in the gripper casing and a clamping element on a wide side of tongue so devised that clamping element bears to some extent on the underside of the gripper casing. At the entry and clamping zone of the yarn, the clamping element takes the form of a thin flat spring strip which follows the curvature of the tongue and which is secured thereto at one end while at a central region the clamping element presses a clamping surface of the gripper casing. When a member moves the tongue away from the gripper casing, the clamping element also disengages from the clamping surface, so that dirt between the clamping surfaces of the tongue element and casing can drop away or be extracted.
