Description

Aluminum rod peeling machine

Technical Field

The invention relates to a device for producing aluminum profiles, in particular to an aluminum rod peeling machine.

Background technique

When producing profiles, aluminum bars must be processed by different equipment before they can enter the extruder for molding production.
