Device and Method for Producing a Film Composite

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a device and method for producing a layered film composite (folienverbund) using a stack of films. The apparatus includes a receiving area for the film stack and an inductor, which is designed and positioned to induce a current in the film stack. This induced current selectively heats parts of the film stack to create the composite structure.

Use CasesContent extracted from patent full text and abstract with AI.

• Manufacturing multi-layered packaging films
• Automated production of laminated films for electronics or displays
• Production of battery separator films
• Creation of specialized protective or barrier materials
• Manufacturing of industrial or medical composite films

BenefitsContent extracted from patent full text and abstract with AI.

• Enables precise and selective heating of film layers
• Allows efficient and uniform lamination or bonding of film stacks
• Reduces processing time and potential thermal damage compared to bulk heating methods
• May improve product consistency and quality
• Facilitates automation of the film composite production process
