Abstract

An improvement to the wire feed rollers used on the Al-Cu TEMESCAL* evaporator, as herein described, allows for a more reliable bidirectional wire feed on that unit. As shown in the top and front views, this improvement involves modifying each wire feed roller by the addition of 8 perpendicular holes of 0.050 Å.013-inch diameter located equally spaced along the center line of the existing roller. Wire feed to the Al-Cu TEMESCAL evaporator, as provided prior to the described modifications, has been very unreliable due to slippage of the wire at the wire rollers. As modified, the sharp edges of the holes are pressed into the soft surface of the feed wire, thereby providing a more positive gripping action and a positive, consistent feed of the wire.

Wire feed to the Al-Cu TEMESCAL evaporator, as provided prior to the described modifications, has been very unreliable due to slippage of the wire at the wire rollers. As modified, the sharp edges of the holes are pressed into the soft surface of the feed wire, thereby providing a more positive gripping action and a positive, consistent feed of the wire. The holes are also large enough that chips, flakes and other Al/Cu particles do not clog the openings as they do on knurled surfaces. * Trademark of Airco Inc.
