01

Pay-off

The machine is supplied together with an unwinder with adjustable height, which is equipped with a spool/wire bundle holder plate and an adjustable mechanical brake.

This plate can be positioned as required, allowing the wire to be unwound along either the vertical or the horizontal axis.

02

Operator Interface Terminal

A programming terminal equipped with a 5.7” touch-screen display allows simple and complete setting of the main straightening parameters, such as:

- Rotation speed of frames 1 and 2
- Direction of rotation of frames 1 and 2
- Straightening speed (m/min)
- Cut length (mm)

Within the same production run, successive batches with different lengths can be programmed (e.g., Batch 1: 1000 pcs with L = 300 mm; Batch 2: 500 pcs with L = 500 mm).

The software makes it possible to perform a quick and effective diagnosis of the machine’s overall condition and to monitor production progress on screen.

03

Straightening unit

Before being straightened, the wire coming from the pay-off can be wrapped around a pulley equipped with an electronically controlled magnetic brake. This device is used to ensure constant tension of the wire entering the straightening unit.

The straightening operation is carried out by means of two counter-rotating frames, each equipped with 5 lapped solid carbide straightening bushes.

To cover the range of wire diameters from 0.1 to 1.0 mm, the APR1000 machine can be equipped with three pairs of frames for different sizes:

- TYPE P (small) - For wire from Ø 0.1 to Ø 0.3 mm
- TYPE M (medium) - For wire from Ø 0.3 to Ø 0.6 mm
- TYPE G (large) - For wire from Ø 0.6 to Ø 1.0 mm

04

Traction unit

The wire is pulled out of the straightening unit by a system with a flat-belt tractor, which prevents any deformation of the straightened wire.

05

High-precision cutting unit

The machine is equipped with a special cutting unit with opposed bushes and an MD insert, driven by a brushless motor that performs the cutting operation extremely quickly and quietly, ensuring excellent cutting quality and a maximum of 1000 cuts per minute.

Accuracy on the length of the wire pieces, equal to +/- 0.1 mm, is guaranteed by the length detection system integrated in the second traction unit, located near the cutting unit.

06

Wire guide and collection tank

Up to the cutting operation, the straightened length remains inside the pneumatically actuated wire guide. After cutting, the guide discharges the wire into the appropriate container. The standard version of the machine is equipped with a wire guide and the corresponding collection tray for a maximum cutting length of 1000 mm.
