The TRUMPF Seam Locker F 125-0 closes simple standing seams and angular standig seams on pre-fabricated sheetmetol assembly parts such as heating and air conditioning ducts or car body components, ( see Figure 2 ). The F 125-0 presses the joined open standing seams together and seals them by hammering.

High working speed, ( approximately 5 meters / minute ), and handy construction make the F 125-0 particularly suited for assembly applications. The free standing tool allows work to be performed even into corners. In addition the F 125-0 has a spring-loaded hammer to avoid tool damage when working various sheet thicknesses and uneven materials.

The distance between hammer and anvil can be easily adjusted. This distance can be as wide as 8 mm allowing sealing strips to be inserted.

• joins mild steel, stainless steel, aluminium and nonferrous metals
• fast and clean closing of prebent standing seams and angular standing seams handy, light-weight machine
• free standing tool closes seams even into corners
• spring-loaded hammer for working a variety of sheetmetal thicknesses
• precision adjustment of working between hammer and anvil overload protection
• change of hammer and anvil without the need for tools • also available as pneumatic version for application in dangerous areas

The Pittsburgh lock seam is the ideal seam connection for straight or curved sheetmetal parts with with pre-formed edges, ( see Figure 1 ), Pittsburgh lock seams provide smooth, aesthetic, and strong connections of superior stability without additional fastening elements. The TRUMPF Seam Locker F 140-0 closes the open Pittsburgh seam in an automatic silent rolling operation. The free-standing flanged edge is closed over the other prebent mating part, without damaging the surfaces.

This fast and safe machine locks straight and curved seams with a minimum radius of 300 mm. Time-consuming and noisy hammering operations are eliminated. Roller and clamping devices together with the automatic feed control of the machine guarantee consistent accuracy of seam, independent of guidance, and high quality of locked seams. As the TRUMPF Seam locker F 140-0 is a portable power tool, it has in many cases the edge over seldom used and therefore expensive stationary machines.

A special bonus is its on-site assembly capability. Ducts or bulky parts can be transported on piles and es practical single components.

• fast, tight closing of Pittsburgh lock seams
• handy, light-weight machine the continous roller principle enables vibration-free locking without hammering
• quiet in operation
• no tools needed for set up for various sheet thicknesses automatic feed without additional force required consistent, high seam quality for straight and curved applications
• economical seam locking on assembly site electronic speed controller

The TRUMPF Spot fastening machine is used for distortion-free, corrosion resistant joining of raw or crooted sheetmetal and is suitable for mild steel, stainless steel and nonferrous materials.

The TF 350-0 uses a novel forming process which simultaneously punches and forms the joint. The oartiolly cut top sheet projects into the bottom sheet which grips the projection, ( see picture ). There is no damage to protective coatings by this purely mechanical process.

This superior, forming and tight fastening technology offers economic and practical advantages. Preparation and finishing operations are eliminated as are the costs for fasteners such as screws and rivets. Cleanly and economically, the TF 350-0 provides long lasting, tight connections. The tool is quiet, requires little energy and is totally free of polluting waste byproducts.

This lightweight, reliable machine is designed to go right to the assembly site, thereby eliminating the need to move heavy, bulky workpieces. An innovative TRUMPF product, low maintenance and simple and safe operation complete the list of advantages.

• handy machine for portable and stationary applications fast, efficient pressure joining guarantees consistent joint quality
• long lasting connection of same or different materials
• form locked, corrosion resistant deep-drawing process, ( cold forming )
• no set-up or finishing work required
• aesthetic, strong connection
• economical and excellent portability
• minimal joint costs without additional costs for fasteners such as rivets or screws practical manoeuvrability, ( working also in upside-down position )
• long tool life
• swivel arms and fixed arms can be changed
• without any problems
• no need to set punch and die environmentally safe, clean operation
