Abstract (en)
[origin: EP0900759A1] The bobbin has a yarn catch opening (3) with longitudinal walls aligned radially at right angles to the longitudinal axis, with a larger gap between them than the thickness of the yarn. The yarn catch opening (3) extends from the clamping slit (4) at least to the point where a tangent at the circumference of the bobbin intersects with the deepest point (8) of the clamping slit (4) at the transit to the catch opening (3).The depth of the yarn catch opening (3) extends at least to a theoretical straight line (9), which runs from the start of the catch opening (3) at the circumference of the bobbin to the deepest point (8) of the clamping slit (4) at the transit to the catch opening (3). The catch opening (3) has the same depth overall. The bobbin is in a sleeve structure, and the catch opening (3) is a window in the bobbin wall (6). The yarn catch opening (3) extends over 45-60° of the circumference, and the clamping slit (4) lies over at least 90° of the circumference.The yarn catch opening (3) is tapered at the ends with a smooth transit into the opening which, otherwise, has a constant width of 1.0-2.5 mm. The depth of the clamping slit (4) is about 50% of the bobbin wall (6) thickness. The clamping slit (4) width is 0-0.2 mm at half the height when not pressed together.The bobbin forms a yarn reserve (5) at the catch opening (3) and clamping slit (4) zone.The catch opening (3) and clamping slit (4) are formed by the cuts of a circular blade in the circumference of the bobbin. Or the clamping slit (4) is cut by a circular blade, and the window is stamped out in the bobbin wall (6) for the catch opening (3). PAPER - The bobbin sleeve is of cardboard, and the like.
