Method and device for producing conductor bars for dynamoelectric machines
First Claim
1. A method for producing conductor bars for dynamoelectric machines, in which the conductor bars are arranged with a main insulation applied when dry, in a pressing device with the interposition of a separating film, are pressed to size in said pressing device and, together with the pressing device, are impregnated with impregnating resin in an impregnating vessel and cured, the method comprising the steps of:
- inserting the dry insulated conductor bars into a pressing device, wherein said pressing device is adapted to the conductor bar shape and surrounds the conductor bar over its entire length and circumference;
pressing the conductor bar and insulation into the final dimension in said pressing device; and
impregnating the conductor bars by inserting the bars and the pressing device into the impregnating vessel which is filled with impregnating resin.

Abstract
In the method for producing conductor bars for dynamoelectric machines, the conductor bars are inserted, with a main insulation (4), applied when dry, into a pressing device with the interposition of a separating film, are pressed to size in said pressing device and, together with the pressing device, are impregnated with impregnating resin in an impregnating vessel and cured.
In order to increase the dimensional accuracy of the conductor bars and to simplify the production method, the dry-insulated conductor bars are inserted (10, 11) individually into a pressing device which is adapted to the bar shape and surrounds the conductor bar over its entire length and circumference and are pressed to the final dimension in said pressing device. Subsequently, a plurality of conductor bars thus prepared are inserted together with the associated pressing device into the impregnating vessel and impregnated there with impregnating resin.
