Multi-Layer Laminate Splicing for Continuous High-Speed Reel Changes

The patent segments the multi-layered laminate into individual layers at the splice point, allowing each layer to be spliced independently. This is achieved by separating the layers longitudinally at the joint between old and new reels, enabling discrete handling and joining of each layer without requiring the entire multi-layer structure to be stationary simultaneously.

The patent applies preliminary action by pre-positioning the new reel adjacent to the old reel before splicing begins. The layers are separated and prepared for joining in advance, with splicing materials applied to outer surfaces before the actual joining occurs. This preparation allows the splicing process to proceed efficiently without requiring extended stationary periods.

The patent extracts the splicing operation from the main production line by performing it at a stationary splice point upstream. Individual layers are separated and spliced independently at this extracted location, allowing the main production line to continue operating with minimal interruption and reducing the need for large festoon buffers.

The patent prepares splicing materials and positions reels in advance at the splice point. Outer surfaces of layers are pre-coated with splicing materials before the actual joining occurs, allowing the splicing process to proceed quickly without requiring large buffers to maintain downstream production continuity.

The patent segments the splicing process into distinct stages: first joining outer surfaces with automated splicing materials, then separating and joining inner layers individually. This segmentation ensures both high-speed automated joining of outer surfaces and proper integration of inner layers, achieving complete layer integration without sacrificing speed.

The patent applies preliminary action by first joining the outer surfaces of the multi-layered laminate with splicing materials before separating and joining the inner layers. This preliminary outer surface joining provides structural stability that enables subsequent inner layer integration while maintaining high splicing speed throughout the process.

The patent implements self-service by designing the splicing system to automatically perform many splicing functions. Splicing materials are automatically applied to outer surfaces, layers are automatically separated and positioned, and the splicing process proceeds with minimal operator intervention. This automation reduces the operator's workload from fully occupied to supervisory level, freeing them for other tasks while maintaining high splicing frequency.

The system performs preliminary actions automatically: splicing materials are pre-applied to outer surfaces, layers are pre-separated and positioned, and splice points are pre-identified. This preliminary automation reduces the complexity and time required for manual splicing operations, allowing operators to manage multiple splicing events without being fully occupied at high speeds.
