Long Sprint NC Roll Feeding machine : A-A Series

It is a long sprint model that can feed a dimension longer than the H series at the same press rotation speed. The press following rotation speed is 600 spm, and the material width can be selected from two models of 400 mm and 600 mm. It is equipped with an automatic thickness adjustment function.

The material releasing mechanism using electromagnet driven by inverter doesn't need compressed air. It provides stable release timing and numerical control about pressure for materials.

The controller 491C automatically adjusts the acceleration from the specified feed length and press rotational speed. In addition, a level meter that monitors the load of the servo motor is also standard installed.

A dedicated rotation sensor must be installed to synchronize with the press machine. As an option, operation with feed and release press cam signal inputs is possible. The maximum press speed is limited to 300spm if the drive system is based on the synchronous press cam signal specification.

Please see the products guide for comparison with other series.

The figure below compares the main performance with H25 of the H series. The A-A series is designed with a feed performance of 300mm at a press speed of 250SPM.

Feed performance table of A-A series are shown in the table below.
Details can be confirmed on the feed performance computing form.

Since the feeding performance of the A-A series varies depending on the weight of the material, it is necessary to calculate the material transfer weight.
