摘要： PURPOSE:To prevent uncontrolled flow of oil at normal temp. by heating oil and fat which are in solid state at normal temp. in a clustered die part and turning into liquid, spraying it in atomized condition for coating, and performing twisting of wire. CONSTITUTION:A core is supplied from a center core supply 1, while an irregularly formed Al covered steel wire supplied from a side wire supply 2. The core and side wire are gathered in a clustered die 4 upon passing through a side wire guide 3, and twisting is conducted. To prevent seizure of the die at this time of twisting, the clustered die 4 is made of a material with greater hardness than aluminum. An atomizer 6 is installed near this clustered die 4 to spray the oil and fat in the twisting process. This atomizer 6 is equipped with an appropriate heating device to perform atomization in liquid state at the time of spraying. Thereby the die is prevented from seizure, and oil outflow after twisting is also prevented.

摘要： PURPOSE:To manufacture by linking a compound trolley wire of high quality by feeding an Al wire inside the container formed by a rotary wheel and fixed block and extruding from a die by feeding via nipple to the outer periphery of a steel wire, in case of the manufacture of a stretch type steel-cored Al conductor compound trolley wire. CONSTITUTION:On the device consisting of the rotary wheel 1 having a groove on the outer peripheral face and the fixed block 7 sliding with one part of the outer peripheral face thereof, the closing wall 8 of said groove is provided. The container 9 for feeding the Al wire as of a coating material is formed by the groove of the rotary wheel 1 and fixed block 7. The conductive Al wire rod 2 as of a coating material is continuously fed into the container 9 and pressfitted into a sub-container 10 via a nipple 4 with the rotary frict ion force of the rotary wheel 1. On the other hand, a steel-cored wire 3 is passed through the hollow hole of the nipple 4, sub- container 10 and the hole of a die 5 and at this time/the stretch type steelcored Al conductor compound trolley wire 6 coated by the Al coating material 2 is formed. Since the Al coating material 2 is linear and continuously fed the generation of a defective trolley wire by the suspension of the Al coating wire 2 is prevented without any suspension.

摘要： PROBLEM TO BE SOLVED: To reduce the possibility of entanglement of a wire to be paid, by winding up the wire in a first layer in which the wire is wound directly around a coreless coil barrel part so that turns of the wire are aligned being adjacent to one another, and by winding up the wire in layers subsequent to the first layer, so that the turns of the wire are separated from one another. SOLUTION: A wire in a fist layer in which the wire is made into direct contact with a barrel part 2 and which is extended from a flange part 4, is wound up to a flange part 3 so that the turns of the wire are adjacent to one another in a so-called aligning winding condition, and after the winding reaches the flange part 3, the winding is changed so that the wire is wound by pitches which are two to five times as large as the wire diameter so as to define an angle 8. The angle in the third layers is set to be larger than that in the second layer. When the outer diameter of the winding of the wire on the inclined barrel part 2 becomes a predetermined value, the traverse range on the flange part 3 side gradually approaches the flange part 4 in a range in which the outer diameter is not exceeded, to that a cylindrical shape is formed. Thereafter, in a tape passing groove serving as a splicing part of the barrel part 2, a steel belt is fastened by a bind, and thereafter, the flange part 4 and the barrel part 2 are removed so as to be disassembled and separated, in order to complete a coreless coil.

摘要： PURPOSE:To provide a packing method for coreless coils by which breakage and movement of wires and entanglement thereof can be prevented. CONSTITUTION:This is a packing method for a coreless coil 1 which is made by disassembling and removing a reel frame, after wire materials or the like are once wound thereon. It is bundled, with a binding material 2 like steel bands immediately before the reel frame is disassembled and removed and after it is removed, the recession 3 of coil brought about by the bundling of the binding material 2 at the middle of the upper face of the coil is filled with a filler 4. After that, whole periphery is covered with a contractive film 5.

摘要： PURPOSE:To stabilize the winding configuration in winding up a metal wire etc. into a pack, by applying minor vibration to the pack during pack forming or after completion thereof. CONSTITUTION:A wire paid off 4 is formed into a coil by a coiler 5 and drops into a pack 1 to be accumulated thereto. A vibrator 7 is installed under a table 6 on which the pack 1 is to be placed, in order to apply minor-scale vertical vibration to the pack 1 during pack forming and the wound wire. The conditions of vibration to be applied depend upon the size of pack 1, the material, size, weight, etc. of the wire 4, preferably with amplitude ranging between 2 and 10mm and the frequency between 50 and 60Hz/s. Thus the winding configuration of the wire being packed is stabilized because of applied vibration to assure transportation without risk of collapse of pack and reduction of the likelihood of wire being cut due to entanglement during use.
