In moving top platen machines, the loading area is also the working area. The ultrasonic tools move vertically in the tooling bridge to weld the work pieces.

Applications:

• Ultrasonic welding, ultrasonic roll seam welding, ultrasonic cutting, ultrasonic punching, ultrasonic riveting and ultrasonic embossing
• Thermoplastics
• Applications in all sectors

Characteristics and advantages:

• Different standardised designs of bridge welding machines, for example
• with crank drive
• with pneumatic drive
• Short travel times with sinusoidal kinematics as a result of crank motion
• Tools can only move vertically
• The loading station is the same as the working station
• Appropriate for ultrasonic surface welding
