Abstract
Longitudinal welding equipment in a machine for packaging products fed on a conveyor belt inside a continuous film of plastic material wrapped around the products with overlapping longitudinal side edges. The equipment comprises a longitudinal welding means positioned above the edges of the means for generating an oscillatory rotary-translational motion on a vertical plane. Furthermore, the equipment provides at least one pressure and accompanying belt a top of the products wrapped inside the film. The welding means and the pressure belt are operatively driven by the same central motor means which actuates said conveyor belt. The welding means is equipped with a means for temperature control operatively connected to the packaging speed.
