摘要： A method of manufacturing a hollow coil spring which is made of a hollow wire in which a terminal sealed portion is formed on an end portion of the wire. The terminal sealed portion has a rotationally symmetric shape in which an axis passing through the center of the wire is the symmetric axis. The hollow coil spring includes an end wall portion, and an end face arc-shaped curved surface. The end wall portion includes an end face perpendicular to the axis. A distal-end-center closure portion is formed on the axis at the center of the end wall portion. A spring seat includes a base member and a sheet member. An end turn portion of the hollow coil spring is in contact with the sheet member. The end face of the end turn portion is opposed to a stopper wall of the spring seat.

摘要： A device for producing a loop at the end of a coil spring has a gripping unit with gripper jaws for retaining the spring in a processing position. The gripping unit is movable to and from the processing position and at least one section of an end turn of the spring protrudes over the gripper jaws. A first slewing gear unit has an output shaft and a coupling section for detachable coupling of a tool for the forming of a loop on the spring through upward bending of the end turn section protruding over the gripper jaws. A counter block attached laterally to the travel direction of the gripping unit is movable over the section of the end turn of the spring protruding over the gripper jaws and has a bending edge as a bending form for producing a loop with the tool.

摘要： Apparatus and methods for use in the manufacture of a spring unit for incorporation into an upholstered article, for example, a mattress, cushion or the like. Coil formation apparatus includes a drive shaft used to control movement of a coil pitch guide member and a link member comprising a connecting rod connected to a radius arm of the drive shaft by means of an adjustable connection. A coil interlinking process comprises compressing a first coil to define a clearance extending a second coil passed the first coil via the clearance, allowing the first coil to extend across the clearance, and contracting the second coil such that the second coil engages the first coil thereby interlinking the first and second coils. Spring unit manufacturing apparatus comprises a plurality of jaw pairs each comprising a first fixed jaw and a pivotal second jaw, the pivotal second jaw being pivoted by a cam and linkage assembly that is operated by a rotary drive shaft.

摘要： Methods and apparatus for forming devices including dead-ends and insulator ties from flat and other strips of material, as well as the devices themselves, are disclosed. Components of these devices may be formed continuously from a single strip, avoiding the need to weld or clamp the components together. Forming the devices in this manner reduces the possibility of stresses or non-uniformities forming when the components are joined and permits continuous automatic or semiautomatic manufacture to occur.
