Abstract: A method of winding fibre to create a tubular winding by using at least three different motions to create interlocking segments. The interlocking segments may have at least one fibre parameter that is different, such as colour. The tubular winding may be bent into a curved shape so that a portion of each of the segments is visible.

Abstract: A stepped-frequency radar signal is transmitted through a barrier. A transmitter of the stepped-frequency radar is on a first side of the barrier, a first object is on a second side of the barrier, and a second object that is distinct from the first object is on the second side of the barrier. A signal including a reflection of the transmitted signal from the first object and a reflection of the transmitted signal from the second object is sensed. The sensed signal is analyzed to determine that a first detection is associated with the first object and a second detection is associated with a second object.

Abstract: A method for winding a skein-shaped windable product onto a spool formed of two spool halves (12, 14) which converge conically towards a middle radial plane (10) with two flange discs (16, 18) at the outer ends, includes the steps of rotating the spool about its central axis during the winding process, and feeding the windable product by a guide that moves along the length of the spool. There is further step of winding the windable product in layers substantially parallel to the lower conical surface up to the top conical surface, and the winding layers end respectively in a cylindrical surface connecting the circumference of the two flange discs (16, 18).

Abstract: In a cross-wound bobbin (1), the helical lines along which the yarn (4) is wound have a different inclination in adjacent layers. The winding ratios are selected such that the quantity drawn off is greater if the unwinding point is moving from the unwinding end to the bottom end, compared to the quantity drawn off if the unwinding point is moving from the bottom end to the unwinding end.

Abstract: A method for forming the wound package of a conical cheese on rotor spinning machines, wherein a crossing angle &agr;M in a central zone of the bobbin traverse is less than 28° and a crossing angle &agr;R in the end zones located adjacent the ends of the wound package is increased in respect to the central zone. The cylindrical cheeses thereby produced are distinguished by long running lengths, solid structure, good density distribution and excellent unwinding properties.

Abstract: By using carbon fibers having a fineness of 25,000 deniers or more, the present invention provides a carbon fiber package including a cheese winding package or a coreless package in which an outside diameter of the package, a diameter of a bobbin or an inside diameter of the package, and a winding width are regulated in the specific ranges, a square-end type package in which a yarn width per fineness, wind angles at the start of winding and at the end of winding, and shifting of the yarn are regulated in the specific ranges, and a carbon fiber packed member in which an average bulk density is regulated in a specific range. Those carbon fiber packages and the carbon fiber packed member solve troubles and inconveniences during use, and also packages which have a high winding density and which do not break easily can be obtained.

Abstract: A method for rolling a rigid vinyl siding elongated sheet of selective dimensions into a convenient transportable compact coil for easier handling and shipping, and products derived from practicing the method. The method includes rolling the sheet onto a spool having a particular axle shape and diameter which varies with the thickness and design of the siding. The shape of the coil may be determined by the shape of the spool axle. For example. the use of a tapered-shaped axle diameter for the spool may produce a substantially conical-shaped coil. Thus, a predetermined length of siding can be rolled with an appropriate spool size to produce a coil product of a desired shape. A method step relates that the granular side of the siding initially contact the surface of the spool and that the smooth side of the siding face outwardly. Fasteners hold the compact coil in a secured manner before the coil is boxed for shipment.

Abstract: A method for producing a coreless coil of strand-like material in which the strand-like material, which may be wire, insulated or non-insulated cable, glass fiber or the like, is wound in several layers on a substantially cone-shaped winding spool. The layers are inclined with respect to the longitudinal axis of the winding spool. The first pair of layers each contain N.sub.1 windings. The second pair of layers each contain N.sub.2 =N.sub.1 +.DELTA.N windings, where N is a constant value. In this manner, the number of windings for consecutive layer pairs is increased until the total number of possible windings for a predetermined winding pitch is reached. The layers of each pair are wound by a take-up apparatus that moves in a first direction for winding one of the layers of a pair and in a second opposite for direction for winding the other layer of the pair. A coreless coil produced by such a method, an apparatus for carrying out the method, and an apparatus for unwinding a coreless coil also are disclosed.

Abstract: A method for preparing an optical fiber canister includes providing a length of a wire (44) having a diameter of about that of the optical fiber (60), and winding the wire (44) onto a mandrel (40) in a preselected winding pattern to form a base layer (46). A replicating strip (48) having a flexible substrate (50) with a patterning layer (52) of b-staged epoxy on one side thereof is provided, and the patterning layer (52) is pressed against the base layer (46) to form a groove pattern (62) in the patterning layer (52). The b-staged epoxy layer (52) is cured to harden it to preserve the groove pattern, and then the flexible substrate (50) is applied to an optical fiber bobbin (56) with the grooved patterning layer (52) facing outwardly. An optical fiber (60) is wound into the groove (62) of the patterning layer (52) to form an optical fiber pack (66).

Abstract: An integral winding machine for winding strand onto a cylindrical package having a hollow core extending axially therethrough and a conical shaped end portion. While maintaining the package stationary, the winding machine receives the strand from a supply source and thereafter winds and deposits the strand in a helical path onto the package, resulting in a uniform, coreless, self-supporting cylindrical package of continuous strand material. The resulting package is adapted to be held stationary while the strand is withdrawn therefrom without introducing any additional twist to the strand. During continuous delivery of the strand material from the supply source for deposit onto the conical shaped end portion of the package, portions of the resulting formed cylindrical package may be regularly removed without stopping the winding process.

Abstract: An optical fiber is joined, preferably with an ultraviolet curable adhesive, to a strip of a flexible support material such as a plastic tape to form an optical fiber assembly. The assembly is wound onto a bobbin to form an optical fiber canister, which is then paid out upon demand. The optical fiber assembly requires little or no adhesive to hold it in place on the bobbin, as the support material of each turn aids in holding the adjacent turns in place, with the result that the bend radius during payout is increased.
