Method for preforming a substantially flat blank of an open clamp
TLDR
In this article, a method and apparatus for preforming a substantially flat blank of an open clamp adapted to be mechanically interconnected near the free ends thereof into a circular clamp having a configuration at least approximately the configuration of the clamp when installed about an object to be fastened onto a relatively fixed, generally circular part is presented.Abstract:
A method and apparatus for preforming a substantially flat blank of an open clamp adapted to be mechanically interconnected near the free ends thereof into a circular clamp having a configuration at least approximately the configuration of the clamp when installed about an object to be fastened onto a relatively fixed, generally circular part; as the flat blank is being fed through the machine, it is preformed into a generally circular shape with the free ends thereof axially spaced from one another; the pair of rollers feeding the blank may also be so shaped in their external contours that the lateral edges of the blank are bent out in the generally radial direction; additionally the blank is automatically stopped after an initial short feed through the machine to permit stamping of a predetermined part of the flat blank; the entire operation which is preferably pneumatically controlled is thereby automatically cyclically operated as soon as a flat blank is inserted into the machine a predetermined distance.read more

Automatic frame bending machine for bending of steel rods or band steel
TL;DR: An automatic frame bending machine for bending off rod steel or steel bands, and a process and device for producing spring mattresses, were presented in this paper, where a spool is provided, after which the steel passes through a wire straightener composed of a rotor and rollers, measurement and traction rollers linked to the bending device, cutting means and a centering metal sheet.

Ring former and cutoff
TL;DR: A ring former and cutoff utilizes a continuous ring former which causes the stock to assume the form of a helix having a number of turns as discussed by the authors, and the leading end of the helix after forming a plurality of free turns passes through a drive roll set, through a stationary cutoff die and into a sizing hoop of larger diameter than those in the turns of the Helix.

Method for manufacturing hose clamps
TL;DR: In this paper, a method and apparatus for manufacturing, handling and installing hose clamps is described, in which the clamp structures are stamped out as flat blanks, and then sent to the user where they are preformed into an ideal shape for assembly about the object to be fastened by bending the free ends of the clamp in mutually opposite directions.
