W. NEAL SERVICES LTD – Manufacturing Rollforming Machinery for over 30 years.
WNS 20swg (1.0mm) PNEUMATIC PITTSBURGH LOCK ROLLFORMERS are 5 station machines and are principally used in the HVAC industry for joining sheet metal at right angles on straight and curved duct sections. Pittsburgh Lock Rolls, auxiliary shafts and an auto guide flanging attachment are fitted as standard. The ‘lock’ is formed in one pass and a flange is inserted into the pocket. The edge is hammered over manually or with a WNS PITTSBURGH LOCK SEAM CLOSER/LOCKER (SC10) & (SC12) or a WNS PITTSBURGH LOCK AIR CLOSING HAMMER (AH18). Additional forming rolls, such as double seam rolls, drive cleat rolls, etc. can be fitted onto the auxiliary shafts. The autoguide flanging attachment enables a right angle to be formed on curved, straight and irregular shapes. The attachment is fitted with a tilting head to enable complete circles to be formed.
This machine is fitted with a quality gast air motor, pneumatic control circuit and emergency stop button. Ideal for use where electric circuits are not permitted such as on and off shore chemical and petroleum installations.
WNS Rollformers are manufactured with all steel side plates. The shafts, forming rolls, gears and guide fences are all hardened, and needle bearings are fitted throughout.
