Abstract: A tape splicing mechanism joins the tail of one tape to the leading edge of another tape. A frame defines a passageway along which the tape passes. A pair of arms rotatably attached to the frame have projecting posts and rotate between a first position where the posts are closer to the pathway and a second position where they are further from the pathway. The arms are urged toward the first position and a catch mechanism holds them in the second position until released by a release mechanism when a release indicia in the first tape passes. The leading edge of the second tape is looped around the first tape to form a loose knot and is tied to the post on each side of the first tape. When the arms are released they move to the second position and tighten the knot.

Abstract: The present invention relates to a process and device for knotting a yarn on a package. The process consists essentially in gripping the end (3) of the yarn and positioning the yarn under tension in prolongation of the last wound turn, in producing a slack loop parallel to the end (3) of the tensioned yarn, then in forming a twist by twisting a length of the slack loop with end (3) of the tensioned yarn, in then tightening the obtained twist on the package (1) and in cutting the remaining end of the yarn. The invention is more particularly applicable in the field of the textile industry, in particularly for the winding of yarns and particularly knotting an end of the yarn on a package.

Abstract: A device which facilitates tying knots, particularly blood knots joining sections of a leader for a fishing line, includes a flexible frame having a base and left and right legs which project away from the base, there being a gap between the two legs. The frame carries a post which projects from the base into the gap intermediate the two legs and may be extended or retracted and even withdrawn. The legs carry winders which rotate about a common axis. Each winder has a hollow interior, a winding arm located at the gap, and a gripping sleeve remote from the gap. Lines or lengths of leader are inserted through the hollow interior of each winder and engaged with the winder arm of the other winder. When the winders are rotated, their arms twist the lines around each other, but the post forms a separation or opening in the wound region of the lines. The tag ends of the lines are inserted through the separation to produce a blood knot which is pulled tight.

Abstract: The accessory tool for anglers comprises two class 1 levers and a fulcrum between them. The levers are flat and rectangular, approximately twice as long as they are wide. They are pivoted on opposite sides of the fulcrum by stubs extending from the fulcrum through mating holes in the levers and held in place by an elastic band which also serves as a resilient element which biases one set of ends of the levers together. These ends are of uneven length so that one end rests against the other to form a pincer for holding ends of lines, leaders or the like. There are two hooks, one on each of these ends, which form an opening when the apparatus is at rest and the pincer closed. When the other ends are pressed together the tips of the hooks part, forming a gap in the opening and the pincer is opened.

Abstract: A knotting method for a netting is disclosed which comprises the steps of seizing together a warp yarn which is paid out from a creel stand and a weft yarn which is paid out from a shuttle to form substantially concentric loops which are opposite in yarn feed direction to each other, pulling out the warp yarn upstream of the loop with respect to a feed direction of the warp yarn through the concentric loops to the opposite side, causing a weft supply side where the weft yarn is paid out to pass through a loop which is formed by the warp yarn as pulled out through the concentric loops, and tightening the warp and weft yarns which are intertwined. The resultant knot is firm and very small.

Abstract: A microprocessor-based control circuit monitors mistie switches provided for the knotter mechanism of a rectangular baler. Each knotter has a switch which is actuated a first time when the knotter cycles and a second time if the knotter ties a knot in a loop of twine around a bale. The control circuit controls a visual display to give an operator a first indication if the knotter does not cycle and a second indication if it fails to tie the knot.

Abstract: A knotter mechanism, utilized on a square baler to encircle the bale with a wrapping material and tie a knot in the material after the wrap is complete, is provided with a detector mechanism for detecting knotter malfunction. The detector mechanism comprises an elongated detector pin which is mounted to pivot in a vertical plane, the pin being mounted on the twine finger of the knotter mechanism so as to pivot therewith in a horizontal plane. The pin is encircled by the wrapping material as the bale is encircled and is within the loop of wrapping material after a knot is tied. As the tied bale is moved rearwardly from the knotter station the detector pin engages the loop of wrapping material and pivots the twine finger thus causing a switch to be actuated. Failure to actuate a switch signals a knotter failure. Upon further movement of the tied bale rearwardly, the loop of wrap material slips over the end of the detector pin and a spring mechanism returns the twine finger and the pin to their initial position.

Abstract: The twine knotter (10) is designed according to the Deering high-pressure system and, as a result of a greater inclination of the knotter hook (26), has a distance (40), measured along the twine strand (25), between the mid-plane of the knotter hook (26) and the pivoting plane of the knife (20) of at least 40 mm, so that the knot ends become longer. Consequently, where thicker baler twine and correspondingly bulkier knots are concerned, the danger that the knot will come loose under tension is reduced.

Abstract: The yarns to be selected are mounted on a selecting rocker pivoting about an axis and are held by a clipper. The yarn is selected by this rocker and is raised by a lever. A finger performs two turns and forms a closed loop of this yarn. An arc-shaped rod which is integral with an arm mounted so as to oscillate about a shaft brings the yarn being knitted into the open end of the finger. A hook takes the closed loop of yarn while oscillating about a vertical shaft and returning to its initial position. It releases this loop and grips the yarn being knitted which is then cut by the clipper actuated by a finger which is integral with the arm and engages with a cam integral with the axis of the clipper. At the same time, the selected yarn is freed by this clipper.
