W. NEAL SERVICES LTD – Manufacturing Rollforming Machinery for over 30 years.
Rollformers create a ‘lock’ which is formed in one pass and a flange is inserted into the pocket. The edge is then hammered over either manually or with a WNS PITTSBURGH LOCK SEAM CLOSER / LOCKER (SC10) & (SC12) or with a WNS 18swg (1.2mm) 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 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.
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.
