Document Type and Number:
Japanese Patent JPS6044125
Kind Code:
A
Abstract:

PURPOSE: To manufacture two or more steel-aluminium composite trolley wire simultaneously and efficiently by passing two or more steel strips through the crosshead of an extruder simultaneously opposing at a proper distance and extruding and covering aluminium etc. on each steel strip.

CONSTITUTION: Two steel strips 2 are inserted into die holes 12, 12 of a die 11 mounted to the crosshead of the extruder along sliding side faces 12a, 12a provided at a distance l; 2W20mm, preferably 2W10mm. At the same time, an aluminium or aluminium alloy 3 is extruded and covered on the steel strips 2 in the extruder. By this way, the steel strips 2 are made eccentric to the sliding face 2a side, and two steel-aluminium composite trolley wires 1 having conductive layers made of aluminium or aluminium alloy and provided with a groove 4 for clamping can be obtained simultaneously and efficiently without requiring any separating process.
