ABSTRACT:
A spring coiling machine comprises two cooperating rotatable wire feeding rollers and a driving device for said wire feeding rollers by which said rollers may be rotated in order to feed a wire in its longitudinal direction between said rollers to a spring forming station, where wire bending tools are provided to cause the wire, as it reaches said station, to be successively bent into a generally helical shape in order to form a coiled spring by being brought into contact with said bending tools with successive portions thereof, and where a separate movable pitch controlling tool is provided to control the pitch of said spring along the length thereof through engagement with said wire. A cam follower is connected to said pitch controlling tool to control the position thereof through cooperation with a movable cam curve operatively connected to said driving device. Said cam curve is arranged for reciprocating rectilinear movement in unison with a reciprocating gear rack included in said driving device.
