This pneumatic machine can be used for the safe interlocking of vented and non-vented roller shutter profiles thus preventing the profiles coming apart during transport. The operator merely needs to insert the profile in the special guide taking care to see that the profile end touches the  mechanical device. By pressing in the profile the unit carries out the following three operations at the same time:

  • the notch at the back of the profile;
  • the insertion of a stainless steel pin of adequate size (length and diameter) in the profile hook;
  • a small chamfer cut on the end of the profile to make it easier to insert in the next profile.

The pins are pointed to facilitate their penetration into the profile, thus ensuring a better grip over the course of time. The pins, which are packed in blisters, are loaded into the special vertical feeding unit which automatically feeds one pin to each profile.  Once the interlocking operation is complete the operator extracts the profile from the guide and slides it manually into the profile he interlocked previously.He repeats this operation until he has assembled a roller shutter of the required length.

The manual pin interlocking unit is mounted on an aluminium baseplate and is equipped with a safety guard made of transparent Plexiglass which also protects the mechanical components. Machine construction complies with the current EC norms.
