VN


The VN-20 is a nail roller that is designed to roll Spiral and Ring forms on nails.

The pre-headed nails are fed from a vibratory feeder into the feed rails of the VN-20, and from the feed rails they are fed in between the rolling dies.

The Spiral or Ring forms are rolled in between the rolling dies.   The nails are fed in between a round rotating die and a moon shaped segment die.

The VN-20 is designed for continuous rolling of nails at a very high production rate, without the need for cooling the rolling dies.

The machine is equipped with quick change devices for easy set-up for:

   ·   Nail length.

   ·   Nail diameter.

   ·   Form length.

   ·   Matching of form marks for spiral flute nails.

   ·   Matching of impressions for ring shank nails.   (No shims needed anywhere).

   ·   Adjustment of the rails in relation to the feeder.

   ·   Adjustment of the feeder on the frame.

The 11 KW (15 HP) spindle motor is driven by an electronic speed controller, allowing infinitely variable speed of the main spindle up to 130 R.P.M.   This feature always enables working at the fastest feed rate available, and allows the operator setting up the machine at a low convenient speed. The R.P.M. is displayed on the speed controller control panel.

The main taper roller bearings and the rolling head are lubricated and cooled by a forced oil system, thus no coolant fluid is necessary and nails are always clean and dry, and can           be immediately processed to the welding station or to the packaging machine.

This machine is equipped with automatic clamping of the nail rolling segment die holder, enabling manual pressure change without using tools.  The automatic clamping also enables recording of the position of the pressure bolts, for quick repetition, when changing from one nail size to another.
