Herrmann Ultrasonics incorporated a thermal sensor in the recently reworked LSM Fin module for continuous longitudinal seals and chained bags on VFFS and HFFS. The ThermoControl process control system monitors the temperature of the material during welding and adjusts the weld process in real time, to stay within the specified parameter window, with the processing of sensitive monomaterials becomes more controllable.
The longitudinal seal module LSM Fin delivers high sealing speeds thanks to its long exposure area and does not require synchronization with the film feed as would be the case with rotating solutions. When sealing at the fin, speeds of up to 120 m/min can be achieved. The anvil can be easily removed using a quick release system. Different contours are available and parallel seals are possible. The sealing blade is easy to replace, while the parameter settings are retained.
