Abstract: A braiding unit moving type braiding apparatus is capable of extremely efficiently braiding apparatus is capable of extremely efficiently braiding on a long mandrel having a curved portion. A braiding layer is formed around a mandrel using the braiding unit. The braiding apparatus includes a braiding unit mover which moves the braiding unit along an axis of the mandrel, and the braiding unit mover includes a drive source which is directly or indirectly provided in the braiding unit, and a first guide and/or a second guide which is aligned with the axis of the mandrel as viewed from above and/or the axis of the mandrel as viewed from the side.

Abstract: The strand guiding device is designed for a circular braiding machine having a braiding point (35) and a first spool (38) for a first strand (37) fed to said braiding point (35). The strand guiding device for strand guiding includes a guide part or guide device (42) for the first strand arranged between the first spool (38) and the braiding point (35), which is movable back and forth to cross the first strand (37) over at least one second strand (32) coming from a respective second spool (31) so that a length of a section of the first strand (37) between the first spool and the braiding point (35) continuously changes, and a device for compensating changes in the length of that section.

Abstract: A tool holder has a housing rotatable about a holder axis, a motor mounted on the housing and having an output rotatable about a motor axis transverse to the holder axis, and a rotation sensor mounted on the housing and coupled coaxially to the motor. A drive wheel mounted on the rotary motor output is rotatable by the motor about the motor axis and is connected to respective wheels of a pair of shafts each having a screwthread. The screwthreads are of opposite hand and respective nuts threaded on the shafts so that rotation of the motor output synchronously rotates the shafts and oppositely displaces the nuts. A tool-holding slide displaceable transversely of the axis on the plate is fixed to the nut of one of the shafts and a counterweight displaceable transversely of the axis on the plate is coupled to the nut of the other shaft.

Abstract: A method for producing packing for the stuffing of boxes, among other purposes. In one embodiment, the packing enables compressive forces to be transmitted uniformly from a gland along an entire winding of the packing so as to eliminate stresses within the packing itself. The method includes a step in which elementary yarns converge to form the packing at an assembly point and a step in which the packing is wound into a coil starting at the assembly point.

Abstract: An apparatus for forming a braided covering over an article, such as a wire harness, which is continuously operable for forming a braided covering throughout the entire length of the wire harness. A sensor, operable in response to movement of the material being utilized for forming the braided covering, is actuable to control the operation of a mechanism for advancing the braided harness out from the zone of braiding operation to permit the continuous braiding of the harness throughout the length thereof. A detector, operable in response to the presence of deformations in the braided harness, controls operation of the advancing mechanism and braiding operation to detect, for example, breaks in the threaded material being supplied for the braiding operation.
