Abstract

The mechanism is particularly for cutting materials for semiconductors, crystals etc. using a wire continuously delivered by a feed mechanism and removed after use. The continuous movement of the wire between the feed and sicharge units is adjustable by a number og guides, which lead it through the cutting plane, Some at least of the guide comprise a series of pulleys on axes at 90 deg. tot he wire and rotating independently of each other, each having a peripheral groove for the wire. Each pulley with its axis is inclined in relation tot he next one, so that the grooves on the two are in line, and the wire passes in a straight line from one to the other.
