PNEUMATIC UNDERPINNERS WITH FIXED NAILING HEAD : JOINT 5x5 serie
Pneumatic machines very easy to use; a simple compressor with a 4l. tank is enough for feeding. Mostly suitable for medium-small profiles not very shaped because it's necessary to move the frame for inserting two or more parallel staples since the machine has a fixed nailing head.
JOINT 5x5 series are two:
- JOINT 5x5A and JOINT 5x5AS operated by a double stroke pedal: first stroke clamps the moulding, second inserts the staple. This kind of functioning makes the machine really convenient but the operator must be careful to the double stroke movement on the pedal.
- JOINT 5x5 N and JOINT 5x5 SUPER have a different working cycle. They work with "pneumatic logic", it means that it's enough to step the pedal and the machines makes a complete working cycle. This allows high working speed and special solutions such as the possibility to work in manual and automatic mode: in this second case, by stepping the pedal the frame is clamped and the joint can be checked before inserting the staples.
