The quick fastening system (3) is designed in such a way that in the second position the nozzle element (1) is immovably fastened to the connecting element (2).

A manufacturing method and an apparatus enable high productivity. A method for manufacturing an oxidized fiber bundle includes joining an upstream precursor fiber bundle and a downstream precursor fiber bundle together with a joining fiber bundle, and oxidizing the joined precursor fiber bundles by feeding the joined precursor fiber bundles through an oxidization furnace. The joining includes applying an oiling agent to a joint area of a joining target precursor fiber bundle before joining the joining target precursor fiber bundle and the joining fiber bundle together. A quantity of the oiling agent adhering to the joint area is 0.15 to 0.85 wt %.

A method improves a winding process of a textile machine and a winding station of a textile machine having a machine controller (11), a yarn sensor (4), a yarn quality monitor, in particular a yarn clearer (5), and a yarn connecting device, in particular a splicing device (3). A yarn (1) is wound onto a bobbin (2). The yarn (1) is analyzed with regard to its length, quality, and/or speed, and is cut if necessary in order to clear a quality defect and two yarn ends are connected to one another by means of the yarn connecting device after the quality defect has been removed. The yarn (1) is analyzed with regard to foreign material, yarn speed, and/or yarn length by means of a capacitive yarn sensor (4), and is analyzed with regard to the yarn body and the yarn characteristic by means of an optical yarn quality monitor. The yarn (1) is subsequently optionally cleared. Data of the capacitive yarn sensor (4) with regard to the foreign material and/or the yarn speed is provided to the yarn quality monitor, in particular the yarn clearer (5), and with regard to the yarn length and/or the yarn speed are provided to the machine controller (11).

A splicing head (100) for a splicing device comprising a splicing chamber and a clamping device (8) for clamping yarns. The clamping device (8) is disposed between two sections (4) of the splicing chamber. The clamping device (8) is arranged independently operable on the splicing head (100), so that the clamping device (8) is operable before and/or after closing the splicing chamber. The splicing head (100) comprises at least one drawing-in element for ensuring that the yarn ends are included in the splicing process, in particular for drawing the yarn ends into the splicing chamber.

A carbon fiber manufacturing method includes joining first and second target fiber bundles with a joining fiber bundle, and carbonizing the joined bundles by feeding them through one or more carbonization furnaces. The joining includes forming an overlap between a first end of the joining fiber bundle and a second end of the first target fiber bundle and jetting a fluid to the overlap to form a first entangled portion, and forming an overlap between a second end of the joining fiber bundle and a first end of the second target fiber bundle and jetting a fluid to the overlap to form a second entangled portion. When the first and second entangled portions each have two or more entangling points with a tensile strength not less than 400 N, the relationship defined by the inequality is satisfied: 40>{L2/(L2−A)}×(S+13), where L2 is a length (mm) of an elongation section inside a first carbonization furnace upstream in a feeding direction of the fiber bundles, A is a maximum distance (mm) between an entangling point in the first entangled portion and an entangling point in the second entangled portion, and S is an elongation (%) of the joined fiber bundles fed through the carbonization furnace.

A fiber bundle joining apparatus includes: a support table configured to hold a terminal end portion side of a first fiber bundle; a roller mechanism having a roller around which a leading end portion side of a second fiber bundle is capable of being wound; a movement mechanism configured to perform a first movement for moving the roller mechanism to the vicinity of the terminal end portion side of the first fiber bundle, and a second movement for further moving the roller mechanism on the terminal end portion side of the first fiber bundle to create a state where the leading end portion side of the second fiber bundle is stacked on the terminal end portion side of the first fiber bundle; and a thermocompression bonding mechanism configured to pressure-bond the first fiber bundle and the second fiber bundle.

A feed yarn joining system for joining a yarn tail end of a yarn package to a yarn head end of a reserve package at a package creel including package storage sites for receiving the yarn and reserve packages, with receiving units for receiving the yarn head end and the yarn tail end, positioning units for positioning a yarn portion joined to the yarn tail end and yarn head end in the yarn splicing device, the yarn splicing device for preparing and joining the yarn head end and yarn tail end, and a control unit for initiating the start of the splicing operation and executing the splicing operation. Furthermore, a package creel arrangement with a feed yarn joining system as well as a method of joining a yarn tail end of a yarn package to a yarn head end of a reserve package when using a feed yarn joining system.
