The LSM Fin longitudinal seal module stands for high quality, continuously manufactured sealing lines on bags (horizontal and vertical) and on chained bags. Easily exchangeable sealing tools allow for an individual and material-saving seal design.
LSM Fin longitudinal seal module
In the LMS Fin, the longitudinal seal is created on the basis of the continuous guidance of the films past the fixed installation tools. This means that the synchronization of rotating tools with the film feed is not necessary. The ultrasonic ensures minimal frictional forces and enables a consistent film movement. Depending on the requirements, various sealing blades are available for determining the seal design.
The generation of the sealing force is pneumatic and set electronically via a proportional control valve. This enables the rapid adjustment of the force during the process and for constant sealing results to be guaranteed – even with a varying production speed.
The LSM Fin is designed so that all the settings are easy to use and easily accessible. The anvil holder with sealing blade can be easily removed for cleaning – all of the settings are saved for the reassembly.
