METHOD AND DEVICE FOR MAKING A CONTINUOUS STRIP OF A HIGHLY ADHESIVE PRODUCT PACKAGED IN A THERMOPLASTIC FILM

摘要

The invention relates to a method for making a continuous strip of a self-sealing product having a very low hardness and being very elastic and highly adhesive, the strip being intended for supplying a transformation machine, wherein the method comprises depositing a protective thermoplastic film at the surface of the strip and includes the following steps: extruding the strip of self-sealing product (P) having a first section (S0); at the outlet of the extrusion die (10), surrounding the entire perimeter of the strip with a thermoplastic film (20) by welding the film on itself; after depositing the film (20) around the strip, rolling the strip so it has a second section (S2) lower than the first section.
