Pittsburgh Seam Closing Machines

 
The Pittsburgh seam is the ideal seam joint on straight
or bent ducts made of pre-formed
pinned together border profiles.

Aesthetically pleasing and solid fittings are produced
without having to use additional fitting elements.
 
The seam locker F 300 i.e. F 301 will lock Pittsburgh
seams by a self acting almost silent roll / sliding process
without damaging the surfaces or metal coatings.

The integral feed ensures constant seam accuracy and
high quality of the seam lock.
 
Thicknesses to 1.5mm can be processed.
Trumpf manufacture a large range of Pittsburgh
closing and seaming machines.
