In the bonding process, the shaped flat wire group is applied with adhesive on one side through a screen which is patterned according to the shape of a final flat wiring harness. As the adhesive hardens, the wires are bonded together and a flat wiring harness of a desired two-dimensional shape is obtained.

Abstract: During the heating of a moving wire (21) such as when the wire is being aaled, the wire is heated in such a manner that the energy applied to each successive increment of length of the wire is substantially constant. This is accomplished by causing an integral number of half cycles of alternating curent to be applied to each successive increment of length of the wire as the increments are moved from one sheave to another in an annealer (20). In one embodiment, the integral number of half cycles is achieved by adjusting the speed at which the wire is being advanced between two sheaves of the annealer in a manufacturing line. This also may be accomlished by adjusting the distance between the sheaves in an annealing leg of the annealer, or by adjusting the frequency of the applied power source.

Abstract: The invention relates to a method of and a device for simultaneously generating heat energy and oscillation energy. In the method heat is generated by induction heating and oscillations are created by means of at least piezoelectric elements. Previously a resonance circuit formed by a series connection of an inductive component and a capacitive, piezoelectric component has been used for the generation of oscillations only. A disadvantage of this kind of circuit has been that the circuit is difficult to control on account of the narrow resonance region of the piezoelectric element. This advantage is avoided in the solution according to the invention in such manner that one and the same resonance circuit formed by a series connection of an inductive and capacitive element generates both heat energy and oscillation energy.

The units are each in a substantially closed condition in the bed and the units close to a single core also in the bed.
