Abstract
A wire-coiling machine has a non-rotating mandrel having a coil-starting portion which declines to a forwardly extending coiling portion. Means revolving about the coil-starting portion continuously feeds and winds under back-tension the wire to be coiled on this coil-starting portion, the latter having a declination and forward extent causing the wire while winding thereon to continuously slide radially downwardly and axially forwardly so as to feed and form coil convolutions on the mandrel's coiling portion while forcing the latter to continuously feed forwardly so as to continuously produce a coil in the form of a non-rotating coil. The mandrel can be very short with a free terminating end from which the non-rotating coil feeds continuously for easy collecting or processing operations.
