Document Type and Number:
Japanese Patent JP2650884
Kind Code:
B2
Abstract:
The fabrication process involves utilising an insulating rod (2) which serves as the insulator core. The path length over the surface is increased by winding the elastomer band (3) over the core. The core is held in a grip (4) and rotatably driven. The elastomer band is extruded from a nozzle (5), which moves linearly parallel to the axis of the core, winding the band onto the core. A wheel (9) running in the grooves between the band windings follows the motion of the nozzle, pressing the band firmly onto the core. The width of the wheel is slightly greater than the pitch between windings of the band. The profile of the band of elastomer delivered from the nozzle is an inverted "T".
