ABSTRACT:
This invention relates to a wire spring forming machine which consists of structure comprising endless wire feeding rollers which move continuously in a wire feeding direction and feed wire without interruption except for the cutting of each spring as it is formed and this is a substantial improvement over the prior art or general use made of segmental or rack gears which require a reversal of movement to a start position of the gears used for each increment of wire fed for each spring formed and which represents a loss of time during which the structure herein would be forming another spring.
