Abstract: An industrial robot device includes a swivel with an attachment mechanism for the attachment of a tool. The attachment mechanism includes at least two different attachment devices for two different kinds of tools. A first attachment device includes a positioning mechanism defining a certain angular position of an attached tool relative to the swivel. A second attachment device is arranged for allowing an arbitrary angular position of an attached tool relative to the swivel. Also contemplated is an industrial robot that is provided with the invented device and to a method for manipulating objects.

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.
