PL-M 1300/2500

In line pre-cutting unit with extruder

The pre-cutting unit PL-M is designed to be used in line with extruders to allow the formation of transversal pre-cuts on the material coming from the extruder before being rewound on the collection table. Pre-cutting is carried out by a special titanium-treated steel blade whose speed self-adjusts based on the speed of the extruder. The rotating blade and the contrast, driven by brushless servo-motors, move synchronously based on the feed’s speed and the set length. The same operating principle is used in the PL-RA model for both in-line operation with extruder
and from reel to reel. In the RA version the pre-cutting unit is inserted in the structure of an automatic winder with spindle feeding from a high capacity hopper, operating in a continuous ‘non-stop’ cycle with automatic unloading of the finished reels. For the reel-to-reel version there is a peripheral unwinder with hydraulic lift to take the reels
to the ground. If the width of the finished reels has to be reduced, the machine can be equipped with a single folding triangle.
