摘要： A pigtailing machine includes a B forming head and a support pedestal secured to a cassette base. The cassette base is located upon a base which mounts the A forming head to provide for a relatively quick changeover should another double pigtail coil spring need be manufactured. By fixing the forming head and the support pedestal to the cassette base alignment and proper manufacture of the spring is assured. Alternatively, the A forming head is also mounted to the cassette base.

摘要： An apparatus is provided for producing coils in the course of a process for the production of binding coils which are to be introduced directly into a row of holes in a pack of sheets. The apparatus has a winding spindle which is surrounded by the coil produced, from which the coil lifts when the front end of the coil is stopped, the winding spindle being driven continuously. A cutting device, for example in the form of scissors is provided for cutting the coil. A device for stopping the front end of the coil periodically is provided between the winding spindle and the cutting device, the stopping device being arranged to operate with a timing correlated with the operation of the cutting device.

摘要： In the automated manufacture of helical coils from sheet-metal blanks, each station of a rotatable set or carrousel of winding stations picks up a flat elongated blank from a stationary loader and securely grips and locks one end in an angled position against a slightly-tapered arbor whose subsequent rotation then causes the blank to become tightly wrapped helically about the arbor while retractable ironing plates stretch-form it and while a second locking mechanism positions the opposite end of the blank untl wrapping is completed. The single thrust of a shaped actuating rod causes a locking member to both position itself and move into a clamping relation with the one end of the blank and the arbor, and both the second locking mechanism and the ironing plates are of toggle-type constructions which enable them to hold securely until positively released. Arbor rotation, and operation of the second locking mechanism, are powered in response to motion of the carrousel relative to stationary structure, and fluid-powered actuators serve to drive the thrust rod and ironing plates under control of detectors responding to angular positions taken up by the carrousel.

摘要： A coil made of a continuous piece of elongated material such as tubing, prebent into pancakelike spirals called radial layers, each radial layer made up of several concentric and coplanar convolutions, with several radial layers stacked axially, and method and apparatus for making such coils. The material is bent prior to coiling at predetermined bending radii which are different for different convolutions within a radial layer. One or more of the convolutions within each radial layer may be bent at constant bending radius; the rest may be bent at gradually changing radii. The bending radius is controlled by an electric and hydraulic network employing both timed and feedback controls. The coil may be built either upwardly, with the most recently made radial layer always at the bottom of the coil, or it can be built downwardly, with the most recently made radial layer always on the top of the coil.
