AI Technical Summary
Conventional book cover machines are limited in their ability to produce diverse book covers efficiently due to the need for precise, complex setup and high-speed adhesive application, which is not feasible at reasonable costs, especially for small and very small runs with varying dimensions.
A device and method featuring a controllable applicator roller and a blank cylinder with a controlled gap, allowing for adhesive application without precise fitting dies, enabling flexible and efficient adhesive transfer to covers, and a transport system that tensions the covers over the applicator roller for uniform adhesive application.
Enables efficient and flexible adhesive application to various cover formats, reducing setup complexity and preventing unwanted adhesive transfer, thus enhancing production variability and quality.
