SIMPLEX RAPID SRL

by Umberto Boschiero
(San Giuliano Milanese - Milano - ITALY)

Since 1948 SIMPLEX-RAPID has been successfully present on all world markets.
The product range has increased over the years.
Our production range covers:

- spring making machines and metal wire processing machines
- wire and tube straightening and wire and tube processing machines
- paper converting machines and envelope making machines
- paper converting work on behalf of third parties

The company has been increasing its market share over the years, thus progressively increasing the size of its own factory, which presently covers an area of 25000 sqm.

SIMPLEX-RAPID’s trade mark has been always a synonym for advanced technology and high construction quality.
Innovation is SIMPLEX-RAPID’s defining feature.
In its long activity, the company has been constantly putting forward revolutionary solutions to increase productivity and handy use of the machines.
After the “Rotary Cut” , the “Graphic Programming” and the "integrated Camera system", SIMPLEX-RAPID presented in 2004 the new PCS - "Pretension Control System"(INTERNATIONAL PATENT) that allows the control of the spring tension.

This optional device, driven by an indipendent motor, moves the coiling tools (rotation) changing the tension of the spring during the coiling cycle.

Advantages:

- Indipendent tension for first and last coil.

- No deformation on the first coil.
- Optimized tension in spring body.
- Best surface quality also with spring with big pitch.
- No mechanical adjustament.
- Reduced set-up time.

PRE-TENSION CONTROL SYSTEM (INTERNATION PATENT)is a
new corner stone for the future of spring coiling.
Thanks to the new “Initial Tension Control Device” it will be possible, even for an un-experienced operator, to overcome all the usual and difficult-to-solve problems related to the initial tension control of any compression spring (i.e. the different amount of initial tension between the first and the last coil).
The revolutionary idea is so effective and so easy to use because it consists of a single axis motion that can be programmed automatically in the same exact way for all spring types (cylindrical, conical, biconical…) independently from wire sizes or spring dimensions.
With this feature it will be possible to control and vary, at any desired point of the wire feed, the amount of initial tension in order to increment or decrement it according to the spring requirement.
No more time consuming and frustrating compromises, just perfect springs in a matter of seconds!
